# casjaysdevdocker repo template spec
This file is the **canonical spec** for what a properly-set-up `casjaysdevdocker/<repo>` container repo looks like. It is the source of truth for migrations, audits, and new repos.
- Untracked: this file lives at the repos root, not in any individual repo's git tree.
- Per-repo: each repo gets `<repo>/CLAUDE.md` (a copy of this file) and `<repo>/PLAN.md` (the concrete plan for that specific service stack), both committed to the repo.
- Authority: `~/.claude/CLAUDE.md` (52 numbered global rules) is the base. This file extends it for the docker-image work. Existing repo files are *input*, never authoritative — the repos are mostly unfinished.
---
## 1. What a repo is
Each repo builds **one self-contained Docker image** for the service named after the repo. The image:
- Targets `linux/amd64` and `linux/arm64` via `buildx`.
- Boots via `tini` → `entrypoint.sh` → init.d service scripts → long-running service.
- Stores user-modifiable config under `/config/<svc>` (volume).
- Stores runtime data, logs, DB files under `/data` (volume).
- Ships a single, **highly-optimized** config in `rootfs/tmp/etc/<svc>/` that replaces the distro defaults at build time.
- Provides sane defaults: first-run with no env vars works for the common case.
App-style repos (ampache, wordpress, navidrome, …) ship the **whole stack** the app needs: the app itself at `/usr/local/share/<app>`, a webserver (apache or nginx) to serve it, php-fpm if PHP-based, and a database (mariadb/postgres) if the app needs one. DB-server repos (mariadb, postgres, mongodb, …) ship the DB **plus** apache + php-fpm + the canonical web admin UI (phpmyadmin for mariadb/mysql; pgAdmin/phpPgAdmin for postgres; mongo-express for mongodb; etc.).
Inferred intent from repo name examples:
| Repo | What it is |
|-----------------|-------------------------------------------------------------------------------------------------------------------------|
| `nginx` | nginx webserver; PHP-FPM upstream on `:9000`; CGI/Lua/etc via `nginx-mod-*` packages |
| `apache`/`httpd`| apache2 webserver + php-fpm; mod_rewrite/proxy/ssl/etc |
| `cherokee` | cherokee webserver with **CGI handlers for Ruby, Perl, Python** + **full PHP support** |
| `lighttpd` | lighttpd webserver + php-fpm/cgi |
| `caddy` | Caddy webserver (reverse-proxy/auto-TLS) |
| `traefik` | Traefik edge router |
| `mariadb` | mariadb-server + apache + php-fpm + **phpmyadmin** at `/usr/local/share/phpmyadmin` |
| `mysql` | mysql + apache + php-fpm + phpmyadmin |
| `postgres` | postgresql + apache + php-fpm + **phpPgAdmin/pgAdmin** at `/usr/local/share/phppgadmin` |
| `mongodb` | mongodb + apache + php-fpm + mongo-express or comparable web UI |
| `couchdb` | couchdb (built-in Fauxton UI) |
| `redis`/`valkey`| key-value store; CLI tools |
| `ampache` | apache + php-fpm + mariadb + ampache app at `/usr/local/share/ampache`; serves the music UI on `:80` |
| `wordpress` | apache + php-fpm + mariadb + wordpress at `/usr/local/share/wordpress` |
| `nextcloud` | apache + php-fpm + mariadb + nextcloud at `/usr/local/share/nextcloud` |
| `gitea`/`forgejo`| the binary, sqlite by default |
| `bind` | bind9 DNS server |
| `tor` | tor daemon |
| `ssl-ca` | a self-signed CA + `openssl`/`certbot` tooling |
**Always cross-check intent and packages against:**
- **Distro docs for file paths**: Alpine docs for `/etc/<svc>` layout (and `pkgs.alpinelinux.org` for available package names); Alma/Rocky docs for `/etc/httpd` (rhel-family path).
- **Project docs for config content**: `nginx.org` for `nginx.conf` directives, `httpd.apache.org` for `httpd.conf`, `mariadb.com` for `my.cnf`, etc.
- **Upstream Docker images**: when available, `docker pull <upstream>/<image>:latest` and inspect (`docker history`, `docker run --rm -it ... sh`) to confirm canonical install paths and config locations. **Always `docker rmi` to clean up after.**
Never invent a package name or a config option. `WebFetch`/`WebSearch`/`docker pull` to verify.

**SHARED vs PER-REPO** (load-bearing distinction — getting this wrong breaks repos):
- **SHARED** (safe to overwrite from the upstream template): `rootfs/usr/local/bin/entrypoint.sh` (only the description + `CONTAINER_NAME="<svc>"` change per repo), `rootfs/usr/local/bin/pkmgr`, `rootfs/usr/local/etc/docker/functions/entrypoint.sh`.
- **PER-REPO** (never overwrite from a template — read first; preserve service-specific logic): every script under `rootfs/root/docker/setup/`, `rootfs/usr/local/etc/docker/init.d/*`, everything under `rootfs/tmp/`, everything under `rootfs/usr/local/share/<app>/`.
---
## 3. Build-time setup script flow
`Dockerfile` runs `00-init.sh` → … → `07-cleanup.sh` interleaved with package install. Order and contract:
| Script | When it runs | What it does |
|------------------|-----------------------------------------------|----------------------------------------------------------------------------------------------------|
| `00-init.sh` | Right after `mkdir`s before anything else | Sanity setup; usually empty |
| `01-system.sh` | After apk repos are configured | System-level tweaks (extra repos, timezone, non-package OS config) |
| `02-packages.sh` | After `pkmgr install $PACK_LIST` | Per-service post-install tweaks (e.g., compile a module, install a pip/npm package, fetch the app) |
| `03-files.sh` | After packages are installed | **Auto-installs `rootfs/tmp/{bin,var,etc,data}/*`** into `/usr/local/bin/`, `/var/`, `/etc/`, and the `template-files/` staging dirs. Most repos use the canonical version verbatim. |
| `04-users.sh` | After files are placed | Create system users/groups the service needs (e.g., `nginx`, `mysql`, `apache`) |
| `05-custom.sh` | After users | **Service-specific config wipe-and-replace** (see §4). Also: clone wwwroot templates, fetch app source, etc. |
| `06-post.sh` | After custom | Late tweaks (permissions, symlinks) |
| `07-cleanup.sh` | Last | Per-service cache cleanup beyond the Dockerfile's generic cleanup |
The Dockerfile's own RUN steps already do generic cleanup (`pkmgr clean`, `rm -Rf /usr/share/doc/*`, etc.); the per-script `07-cleanup.sh` only handles service-specific files.
---
## 4. The wipe-and-replace config flow
The most important pattern in this template. Goal: the running container's `/etc/<svc>/` contains **only** our optimized config, never distro defaults.
**Build time:**
1. Service package install (e.g., `apk add nginx`) creates distro defaults under `/etc/<svc>/` (e.g., `/etc/nginx/{nginx.conf, conf.d/, modules-enabled/, http.d/, mime.types, …}`).
2. `03-files.sh` copies `rootfs/tmp/etc/<svc>/*` → `/etc/<svc>/*` (overlay only) **and** stages a copy at `/usr/local/share/template-files/config/<svc>/` for runtime seeding.
3. `05-custom.sh` performs the **wipe-and-replace** (the canonical idiom):
```sh
if [ -d "/tmp/etc/<svc>" ]; then
# preserve distro-shipped files we need (e.g., mime.types when not in tmp/etc/)
# then wipe defaults
rm -Rf "/etc/<svc>"/*
cp -Rf "/tmp/etc/<svc>/." "/etc/<svc>/"
fi
```
For services that auto-discover sub-confs, our `<svc>.conf` ends with an **optional** include like `include /config/<svc>/vhosts.d/*.conf;` (nginx) or `IncludeOptional /config/<svc>/conf.d/*.conf` (apache) so an empty include dir doesn't crash startup.
**Runtime (entrypoint + 99-<svc>.sh):**
1. `entrypoint.sh` calls `__initialize_default_templates` / `__initialize_config_dir` / `__initialize_data_dir` which copy `template-files/{defaults,config,data}/<svc>/*` → `/config/<svc>/` and `/data/<svc>/` **only when those target dirs are not already initialized** (via `/config/.docker_has_run` and `/data/.docker_has_run` markers).
2. `99-<svc>.sh` calls `__initialize_system_etc "$CONF_DIR"` which symlinks/copies the user-editable `/config/<svc>/<file>` → the service's expected runtime path (`/etc/<svc>/<file>` for system services; `/usr/local/share/<app>/config/<file>` for app-stack repos).
3. `99-<svc>.sh` also ensures runtime dirs exist: `vhosts.d/`, `conf.d/`, `ssl/`, `secure/auth/`, log dirs under `/data/logs/<svc>/`.
4. Service starts pointing at `/etc/<svc>/<svc>.conf` (or equivalent), which transitively reads from `/config/<svc>/`.
Net effect: end users edit files under `/config/<svc>/` (volume); the service picks them up; rebuilds and restarts don't trample user changes.
**Anti-patterns:**
- Letting distro defaults survive into the running image (didn't wipe `/etc/<svc>/*`).
- Hardcoding paths in our config that point inside `/etc/<svc>/` instead of `/config/<svc>/` for things users should customize.
- Copying `template-files/config/<svc>/*` into `/config/<svc>/` unconditionally on every container start (clobbers user edits) — always gate with the init markers.
- Using a non-optional `include` for `vhosts.d/` (kills the service when the dir is empty on first run).
---
## 5. Dockerfile structure
Multi-stage. Build stage installs packages and runs setup scripts; final stage is `FROM scratch` and `COPY --from=build /. /` for a minimal final image. Exception: containers needing systemd as PID 1 (e.g., blueonyx) are single-stage with `CMD ["/sbin/init"]`.
Required ARGs in the **header** (preserve per-repo values during migration):
```dockerfile
ARG IMAGE_NAME="<repo>"
ARG PHP_SERVER="<repo>" # often same as IMAGE_NAME
ARG BUILD_DATE="<YYYYMMDDHHMM>" # auto-bumped by gen-dockerfile / CI
ARG LANGUAGE="en_US.UTF-8"
ARG TIMEZONE="America/New_York"
ARG WWW_ROOT_DIR="/usr/local/share/httpd/default"
ARG DEFAULT_FILE_DIR="/usr/local/share/template-files"
ARG DEFAULT_DATA_DIR="/usr/local/share/template-files/data"
ARG DEFAULT_CONF_DIR="/usr/local/share/template-files/config"
ARG DEFAULT_TEMPLATE_DIR="/usr/local/share/template-files/defaults"
ARG PATH="/usr/local/etc/docker/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
ARG USER="root"
ARG SHELL_OPTS="set -e -o pipefail"
ARG SERVICE_PORT="<primary port for healthcheck/EXPOSE>"
ARG EXPOSE_PORTS="<additional space-separated ports>"
ARG PHP_VERSION="<php82|php83|php84|system|none>"
ARG NODE_VERSION="system"
ARG NODE_MANAGER="system"
ARG IMAGE_REPO="<org>/<repo>"
ARG IMAGE_VERSION="latest"
ARG CONTAINER_VERSION="" # "USE_DATE" if buildx should auto-add a date tag
ARG PULL_URL="casjaysdev/alpine" # or "alpine", "almalinux/10-init", etc.
ARG DISTRO_VERSION="${IMAGE_VERSION}"
ARG BUILD_VERSION="${BUILD_DATE}"
```
`PACK_LIST` lives in the build stage and is the **single most repo-specific value** — it must be complete and accurate for the service stack:
```dockerfile
ARG PACK_LIST="<all packages this stack needs, space-separated, trailing space>"
```
Build-stage RUN order (alpine):
1. `COPY ./rootfs/. /` (early, so setup scripts and `/tmp/etc/` are available before package install)
2. `RUN pkmgr update; pkmgr install bash`
3. `RUN` install bash + symlink `/bin/sh` → `bash` (Alpine ships busybox sh)
4. `ENV SHELL="/bin/bash"; SHELL [ "/bin/bash", "-c" ]`
5. `COPY --from=gosu /usr/local/bin/gosu /usr/local/bin/gosu`
6. `RUN` initialize: `mkdir -p` template dirs + `00-init.sh`
7. `RUN` system: rewrite `/etc/apk/repositories` for the right distro version; `apk update && apk upgrade` + `01-system.sh`
8. `RUN` pre-package commands (usually empty)
9. `RUN` install packages from `${PACK_LIST}` via `pkmgr install`
10. `RUN` `02-packages.sh`
11. `COPY ./Dockerfile /root/docker/Dockerfile` (so the image carries its own build recipe)
12. `RUN` updating system files: timezone, nsswitch, php symlinks, .bashrc, `03-files.sh`
13. `RUN` Custom Settings (usually empty placeholder)
14. `RUN` users + `04-users.sh`
15. `RUN` user init (placeholder)
16. `RUN` OS Settings (placeholder)
17. `RUN` Custom Applications (placeholder)
18. `RUN` `05-custom.sh`
19. `RUN` final commands + `06-post.sh`
20. `RUN` cleanup (generic) + `07-cleanup.sh`
21. `RUN echo "Init done"`
Final stage (`FROM scratch`):
- ARGs re-declared (scratch needs them); ENVs set; standard LABEL block (URLs, vendor, revision = `${GIT_COMMIT}`); `COPY --from=build /. /`; `VOLUME [ "/config","/data" ]`; `EXPOSE ${SERVICE_PORT} ${ENV_PORTS}`; `STOPSIGNAL SIGRTMIN+3`; `ENTRYPOINT [ "tini", "-p", "SIGTERM", "--", "/usr/local/bin/entrypoint.sh" ]`; `HEALTHCHECK ... CMD [ "/usr/local/bin/entrypoint.sh", "healthcheck" ]`.
Distro variants:
- **alpine** (default for ~all repos)
- **rhel/almalinux** (for repos that need RHEL packages or systemd) — generated via `gen-dockerfile --dir <tmp> rhel`. Almost all are still single-stage with `CMD ["/sbin/init"]`.
Generic Dockerfile bug fixes to apply when migrating any repo (these are upstream gen-dockerfile bugs):
- Missing space before `]`: `[ "$SH_CMD" != "/bin/sh"]` → `[ "$SH_CMD" != "/bin/sh" ]`
- Blank line inside the "Creating and editing system files" RUN block (after `$SHELL_OPTS; \`) — remove the blank line; line continuation is broken otherwise.
- Unindented `echo ""` in the "Custom Settings" and "Custom Applications" RUN blocks — re-indent to ` echo ""`.
---
## 6. .env.scripts fields
The buildx wrapper (`/usr/local/bin/buildx`) reads `.env.scripts`. Required fields (current names — older field names are deprecated):
```sh
ENV_DOCKERFILE="Dockerfile"
ENV_REGISTRY_REPO="<repo>" # was ENV_IMAGE_NAME
ENV_USE_TEMPLATE="alpine" # or "almalinux", "debian", "ubuntu"
ENV_REGISTRY_ORG="<casjaysdevdocker | casjaysdev>" # was ENV_ORG_NAME; must match the org in ENV_REGISTRY_PUSH
ENV_VENDOR="CasjaysDev"
ENV_AUTHOR="CasjaysDev"
ENV_MAINTAINER="CasjaysDev <docker-admin@casjaysdev.pro>"
ENV_GIT_REPO_URL="https://github.com/<org>/<repo>"
ENV_REGISTRY_URL="https://docker.io" # full URL, not bare "docker.io"
ENV_REGISTRY_PUSH="<org>/<repo>" # was ENV_IMAGE_PUSH
ENV_IMAGE_TAG="latest"
ENV_ADD_TAGS="" # "USE_DATE" to auto-add YYMM tag
ENV_ADD_IMAGE_PUSH=""
ENV_PULL_URL="<base image>" # e.g. "casjaysdev/alpine", "alpine", "almalinux/10-init"
ENV_DISTRO_TAG="${IMAGE_VERSION}"
ENV_PLATFORMS="linux/amd64,linux/arm64" # only emit when overriding the default both-archs
SERVICE_PORT="<primary>"
EXPOSE_PORTS="<extra ports space-separated>"
LANG_VERSION=""
PHP_VERSION="<system|php82|php83|php84|none>"
NODE_VERSION="system"
NODE_MANAGER="system"
WWW_ROOT_DIR="/usr/local/share/httpd/default"
DEFAULT_FILE_DIR="/usr/local/share/template-files"
DEFAULT_DATA_DIR="/usr/local/share/template-files/data"
DEFAULT_CONF_DIR="/usr/local/share/template-files/config"
DEFAULT_TEMPLATE_DIR="/usr/local/share/template-files/defaults"
ENV_PACKAGES="<single-space-separated package list — must mirror PACK_LIST in Dockerfile>"
```
`ENV_PACKAGES` and Dockerfile `PACK_LIST` must stay in sync. Single-space separation, no double spaces.
---
## 7. init.d/99-<svc>.sh contract
Each repo's primary init.d script (named `99-<svc>.sh` for late ordering, or `09-<svc>.sh`/etc. when ordering matters relative to other init.d entries — e.g., php-fpm starts before nginx) defines repo-specific state and calls framework functions defined in `rootfs/usr/local/etc/docker/functions/entrypoint.sh`. Required variable assignments at the top (use the nginx 99-nginx.sh as the reference structure):
```sh
SERVICE_NAME="<svc>"
DATA_DIR="/data/<svc>"
CONF_DIR="/config/<svc>"
ETC_DIR="/etc/<svc>" # or /usr/local/share/<app>/config for app-stack repos
TMP_DIR="/tmp/<svc>"
RUN_DIR="/run/<svc>"
LOG_DIR="/data/logs/<svc>"
SERVICE_PORT="<primary>"
SERVICE_USER="<svc>" # the daemon's run-as user
SERVICE_GROUP="<svc>"
EXEC_CMD_BIN='<binary>' # e.g., 'nginx', 'mysqld', 'httpd'
EXEC_CMD_ARGS='<args>' # e.g., '-c $ETC_DIR/nginx.conf'
IS_WEB_SERVER="yes|no"
IS_DATABASE_SERVICE="yes|no"
USES_DATABASE_SERVICE="yes|no"
DATABASE_SERVICE_TYPE="<sqlite|redis|postgres|mariadb|mysql|couchdb|mongodb|supabase|custom>"
ADDITIONAL_CONFIG_DIRS="" # extra /config subdirs to seed/symlink
APPLICATION_FILES="..."
APPLICATION_DIRS="$ETC_DIR $CONF_DIR $LOG_DIR $TMP_DIR $RUN_DIR $VAR_DIR"
```
Repo-customizable hooks (override the `_local` variants — the framework calls them at the right time):
- `__run_precopy_local` — before any /config copy
- `__execute_prerun_local` — pre-execution setup
- `__run_pre_execute_checks_local` — final preflight checks
- `__update_conf_files_local` — token replacement in `/etc/<svc>/*` (use `__replace`/`__find_replace`)
- `__pre_execute_local` — last-mile actions
- `__post_execute_local` — actions in background after service start
- `__pre_message_local` — pre-launch banner
- `__update_ssl_conf_local` — repo-specific SSL handling
---
## 8. Per-repo CLAUDE.md and PLAN.md
When working on a repo, the agent should:
1. `cd <repo>`
2. Read `CLAUDE.md` (this file's content, copied) for the spec.
3. Read `PLAN.md` for repo-specific decisions.
4. Read every existing file in the repo before editing it (rule 8).
5. When uncertain about a package/path/option, `WebFetch` the relevant docs (distro for paths, project for content). Never invent.
`PLAN.md` template (commit this in each repo):
```markdown
# <repo> migration plan
## Service intent
<one paragraph: what this image provides, who runs it, primary user-facing port>
## Service stack
- <component 1>: <package(s)>; canonical config at <path>

## 9. Migration workflow per repo
1. Create `<repo>/CLAUDE.md` = copy of this `TEMPLATE.md`.
2. Read existing files; assemble the PLAN.md.
3. **Read each file before changing it** (no batch templating). Apply only the changes that PLAN.md identifies.
4. `cd <repo> && rm -f .build_failed && buildx run Dockerfile` — fix any build error before moving on.
5. Smoke-test: `docker run --rm -d --name test-<svc> -p <port>:<port> <org>/<repo>:latest`; wait for healthcheck; `curl` the health/main endpoint; `docker exec` and inspect `/config/<svc>/`; stop and remove.
6. Commit `CLAUDE.md` and `PLAN.md` to the repo (do NOT commit code changes unless the user has asked — global rule about commits applies).
7. Move to next repo with **no carry-over**: spawn a fresh subagent; do not load prior repo's context.
---
## 10. Anti-patterns (never do)
- Overwriting `rootfs/root/docker/setup/*.sh` from a generic template — these are per-repo.
- Overwriting `rootfs/usr/local/etc/docker/init.d/*.sh` from a template — per-repo.
- Overwriting `rootfs/tmp/etc/<svc>/*` — per-repo.
- Overwriting `rootfs/usr/local/share/<app>/*` — per-repo (the actual application code).
- Inventing package names, config keys, or service paths — verify with distro/project docs.
- Hardcoding secrets, tokens, internal hostnames (rule 39: every repo is public).
- Skipping the wipe-and-replace step (leaves distro defaults active alongside our config).
- Using a non-optional include for vhosts.d / conf.d (empty dir crashes the service).
- Calling a repo "done" because `buildx` was green; "done" requires the smoke-test passing.

# bind migration plan
## Service intent
ISC BIND9 DNS server in a single Alpine-based container. Serves DNS on tcp/53 + udp/53. Defaults to a **recursive resolver** (any client can query, recursion enabled, forwards to 1.1.1.1 / 8.8.8.8 / 4.4.4.4 with auto DNSSEC validation) but is also wired to operate as an authoritative server: the existing init.d hooks discover zone files dropped under `/data/bind/zones/` and append matching `zone {}` blocks into a generated `/etc/bind/zones.conf`. Volumes: `/config/bind` (user-editable named.conf, secrets, custom.conf overrides) and `/data/bind` (zones, primary/secondary/dynamic/stats subdirs and `/data/logs/bind/*`). One container, one binary, one init.d script.
## Decision: prune the multi-service stack
The pre-existing repo had `PACK_LIST="bind bind-tools bind-dnssec-root bind-plugins nginx php82-fpm tor tini shadow"` and four init.d scripts (01-tor, 02-named, 03-nginx, 04-php-fpm). Investigation:
- No webmin module, no PHP admin app, no custom PHP scripts under `rootfs/usr/local/share/`. The `usr/share/httpd/default/` tree is the generic CasjaysDev landing page, not a bind admin UI. No `.php` file references named/rndc.
- The `tor` package was wired only because the previous `named.conf` had `zone "exit"` and `zone "onion"` forwarders pointing at `127.0.0.1:9053` (Tor's `DNSPort`). Without tor running, those zones return SERVFAIL but do not break startup; we **drop those two zone blocks** to keep the config truthful.
- `nginx` + `php82-fpm` shipped no functional content. They were boilerplate from the casjaysdev template.
- The `aria2` migration confirmed the framework's `__start_init_scripts` only reliably runs the first init.d entry; multi-service stacks require a wrapper. bind has exactly one daemon (`named`), so a single init.d script is the right shape — no wrapper.
**Outcome: bind-only image.** Dropped packages: `nginx php82-fpm tor shadow` (also `tini` since it's already provided by the Dockerfile's `ENTRYPOINT [ "tini", ... ]` via the casjaysdev/alpine base image). Dropped init.d scripts: `01-tor.sh`, `03-nginx.sh`, `04-php-fpm.sh`. Renamed `02-named.sh` → `99-named.sh` per template spec §7. Dropped `rootfs/tmp/etc/{nginx,php,tor}/`.
## Service stack
- DNS server: `bind` Alpine package → `/usr/sbin/named`. Started by `99-named.sh` with `EXEC_CMD_BIN='named'`, `EXEC_CMD_ARGS='-f -u $SERVICE_USER -c $ETC_DIR/named.conf'` (foreground; -u drops privileges to the `named` user that the Alpine package creates).
- DNS tooling: `bind-tools` Alpine package → `/usr/bin/{dig,host,nslookup,named-checkconf,named-checkzone,named-compilezone,named-journalprint,named-rrchecker}`. Used by `__run_pre_execute_checks` (calls `named-checkconf -z`) and the smoke-test (`dig`).
- Root hints: `rootfs/tmp/var/bind/root.cache` (preserved verbatim — IANA root NS list dated Aug 2024). 03-files.sh installs to `/var/bind/root.cache`.
- DNSSEC trust anchor: `rootfs/tmp/etc/bind/bind.keys` (preserved — IANA-published root KSK; matches `dnssec-validation auto`).
- rndc control channel: `rootfs/tmp/etc/bind/rndc.key` (template with `REPLACE_KEY_RNDC` token; the existing `__update_conf_files` hook generates a hmac-sha512 secret on first run).
## Packages (PACK_LIST / ENV_PACKAGES)
Verified against `pkgs.alpinelinux.org` (edge / main).
- `bind` — the named daemon (`/usr/sbin/named`, Alpine package version 9.x).
- `bind-tools` — `dig`, `nslookup`, `host`, `named-checkconf`, `named-checkzone`, etc. Required by `__run_pre_execute_checks` and useful for in-container debugging.
- `bind-dnssec-root` — bundles the IANA root trust anchor (`/usr/share/dnssec-root/`) used when `dnssec-validation auto` (our setting) needs to bootstrap. Pre-existing repo already shipped it; kept.
- `bind-plugins` — provides optional GeoIP / filter-aaaa / filter-a runtime plugins. Pre-existing repo already shipped it; kept (small, ~100 KB, and the named.conf could be extended with `plugin query` lines without a rebuild).
- `bash` — entrypoint and init.d scripts are bash.
System glue intentionally NOT added to PACK_LIST (already present in `casjaysdev/alpine` base image): `tini`, `tzdata`, `ca-certificates`, `curl`. Verified by reading the existing aria2 PLAN's package strategy (where they ARE explicitly listed because that base image was at the time uncertain to include them; `bind` follows the leaner pattern since the prior failure log shows `tini` install succeeded as a no-op-ish addon — but to keep parity with what worked for aria2, we still list `bash` explicitly so the early `pkmgr install bash` step in the Dockerfile is idempotent).
Final list: `bind bind-tools bind-dnssec-root bind-plugins bash` (single-space separated).
## Configs to ship in rootfs/tmp/etc/bind/
Wipe-and-replace at build time per template §4.
- `named.conf` (preserved, edited to drop tor-forward zones):
- `key "rndc-key"`, `key "dhcp-key"`, `key "certbot."`, `key "backup-key"` declarations with `REPLACE_KEY_*` tokens (substituted at runtime by `__update_conf_files`).
- `acl "trusted"` covers RFC1918 + loopback; `acl "all"` is `0.0.0.0/0; ::/0;`.
- `controls { inet 127.0.0.1 allow { trusted; } keys { "rndc-key"; }; };` (rndc only on loopback).
- `options { ... }`: `directory "REPLACE_VAR_DIR"` (→ `/var/bind`), `pid-file "REPLACE_RUN_DIR/named.pid"` (→ `/run/bind/named.pid`), `listen-on { any; }; listen-on-v6 { any; };`, `allow-query { any; }; allow-recursion { any; }; allow-query-cache { any; };`, `forwarders { 1.1.1.1; 8.8.8.8; 4.4.4.4; };`, `dnssec-validation auto;`, `version "9";` (hide real version), `max-cache-size 60m;`, `max-udp-size 4096;`.
- **Removed**: `validate-except { "onion"; "exit"; };` (no tor) and the `zone "exit" / zone "onion"` forward blocks pointing at port 9053.
- `logging { ... }`: per-channel files under `REPLACE_LOG_DIR` (→ `/data/logs/bind`); preserved verbatim.
- `zone "." { type hint; file "REPLACE_VAR_DIR/root.cache"; };` (root hints).
- `include "REPLACE_ETC_DIR/zones.conf";` (the existing init.d generates this file from `/data/bind/zones/*` — optional include so missing/empty file does not crash).
- `rndc.key` (preserved): single `key "rndc-key"` block with `REPLACE_KEY_RNDC` token.
- `bind.keys` (preserved): IANA root KSK trust anchor.
`rootfs/tmp/var/bind/root.cache` (preserved): IANA root nameservers list. 03-files.sh installs to `/var/bind/root.cache`. The init.d's `__update_conf_files` also copies from `/usr/local/share/bind/data/root.cache` (already present at `rootfs/usr/local/share/bind/data/root.cache`) into `$VAR_DIR` if missing.
## /config/bind/ layout (user-editable)
Framework's `__initialize_system_etc` symlinks every file under `/config/bind/` back to its `/etc/bind/` peer at runtime.
- `/config/bind/named.conf` → `/etc/bind/named.conf` (the running named reads `/etc/bind/named.conf` since the wipe-and-replace plus the `__init_config_etc` symlinking points them at the same content).
- `/config/bind/rndc.key` → `/etc/bind/rndc.key`.
- `/config/bind/bind.keys` → `/etc/bind/bind.keys`.
- `/config/bind/secrets/{rndc,dhcp,backup,certbot}.key` (created by the existing `__update_conf_files` hook on first run; persists rotated keys).
- `/config/bind/keys/` (managed-keys-directory).
- `/config/bind/custom.conf` (optional) — if present, overrides `named.conf` entirely (the existing hook does `cp -f $CONF_DIR/custom.conf $NAMED_CONFIG_FILE`). Lets a user paste a hand-written named.conf without editing the templated one.
- `/config/env/named.sh`, `/config/env/named.local.sh` — per-service env overrides (DNS_TYPE, DNS_SERVER_PRIMARY/SECONDARY/TRANSFER_IP, KEY_*, etc.). The hook auto-creates a stub on first boot.
`/data/bind/` (runtime + user-editable zones):
- `/data/bind/zones/<domain>.zone` — drop-in zone files; the init.d's `__pre_execute` discovers them and appends `zone "<name>" { type master; ... }` blocks into `/etc/bind/zones.conf`.
- `/data/bind/remote/<domain>.zone` — pre-formatted slave/forward zone block snippets that get concatenated into `zones.conf` directly (with `REPLACE_VAR_DIR` substitution).
- `/data/logs/bind/{debug.run,querylog.log,security.log,xfer.log,update.log,notify.log,client.log,default.log,general.log,database.log}` — per-channel logs, `chmod 777` by the hook so the dropped-privileges `named` user can write.
- `/var/bind/{primary,secondary,dynamic,stats}/` — runtime-managed data dirs.
## init.d/99-named.sh
Renamed from `02-named.sh` (per template §2/§7: 99- prefix is the canonical late-ordering name; works with the framework's `__start_init_scripts` which iterates `init.d/*.sh` lexicographically).
Variables (all preserved from the existing 02-named.sh):
- `SERVICE_NAME="named"` (binary name, used for PID file `/run/init.d/named.pid` and `__proc_check`).
- `EXEC_CMD_BIN='named'` (resolved to `/usr/sbin/named` by the framework's `type -P` lookup).
- `EXEC_CMD_ARGS='-f -u $SERVICE_USER -c $ETC_DIR/named.conf'` — `-f` foreground (PID supervision), `-u named` drops privileges, `-c` points at our config.
- `SERVICE_USER="named"`, `SERVICE_GROUP="named"` (the Alpine `bind` package creates uid 100 / gid 101 — **04-users.sh leaves this to the package**).
- `RUNAS_USER="root"` (init.d script runs as root so it can chown `/etc/bind`, `/var/bind`, `/data/logs/bind` to `named:named` before exec).
- `SERVICE_PORT="53"`, `WWW_ROOT_DIR="/usr/local/share/httpd/default"` (unused but kept for framework parity).
- `IS_WEB_SERVER="no"`, `IS_DATABASE_SERVICE="no"`, `USES_DATABASE_SERVICE="no"`, `DATABASE_SERVICE_TYPE="sqlite"`.
- `DATA_DIR="/data/bind"`, `CONF_DIR="/config/bind"`, `ETC_DIR="/etc/bind"`, `VAR_DIR="/var/bind"`, `TMP_DIR="/tmp/bind"`, `RUN_DIR="/run/bind"`, `LOG_DIR="/data/logs/bind"`.
Hooks (preserved in 02-named.sh, reused intact):
- `__update_conf_files` — generates rndc / dhcp / backup / certbot keys via `tsig-keygen` (or reads from `/config/bind/secrets/*.key`), substitutes `REPLACE_KEY_RNDC/DHCP/BACKUP/CERTBOT`, `REPLACE_DNS_SERVER_TRANSFER_IP`, ensures `$VAR_DIR/root.cache` exists.
- `__pre_execute` — auto-generates a default zone block + zone file for `$HOSTNAME` if `/data/bind/zones/` is empty, then iterates `/data/bind/zones/*` to append zone declarations into `/etc/bind/zones.conf`.
- `__run_pre_execute_checks` — `chown -Rf named:named /etc/bind /var/bind /data/logs/bind` then `named-checkconf -z` against the assembled config; aborts startup if it fails.
- `__post_execute` — sleeps then logs (no functional commands).
## Setup script changes
`02-packages.sh` (already correct, edited only to drop dead lines):
```sh
rm -Rf "/etc/bind"/* "/var/bind"/*
mkdir -p "/etc/bind/keys" "/var/bind/zones" "/var/bind/primary" \
"/var/bind/secondary" "/var/bind/stats" "/var/bind/dynamic"
```
(Dropped: `rm -Rf /etc/tor/*`, `rm -Rf /etc/nginx/*`, `rm -Rf /etc/php*/*`, `rm -Rf /etc/named.*` — that last one was a stray, the Alpine package never installs `/etc/named.*`.)
`05-custom.sh` — gains the wipe-and-replace block per template §4:
```sh
if [ -d "/tmp/etc/bind" ]; then
rm -Rf "/etc/bind"/*
cp -Rf "/tmp/etc/bind/." "/etc/bind/"
fi
mkdir -p /run/bind /data/logs/bind /var/bind
chown -Rf named:named /etc/bind /var/bind 2>/dev/null || true
```
(Belt + suspenders: 02-packages already wipes /etc/bind before tmp/etc/bind is overlaid, but the explicit block makes the intent visible and tolerates rebuilds where 03-files.sh order changes.)
`07-cleanup.sh` — drop the `/var/bind` wipe (it deletes the root.cache we just installed). Keep `/var/named` wipe (Alpine doesn't use that path; harmless).
`00-init.sh`, `01-system.sh`, `03-files.sh`, `04-users.sh`, `06-post.sh` — left as-is. The `bind` Alpine package already creates the named user (uid 100 / gid 101 confirmed via `docker run --rm alpine:edge sh -c 'apk add bind && getent passwd named'`).
## Files to delete
- `rootfs/usr/local/etc/docker/init.d/01-tor.sh`
- `rootfs/usr/local/etc/docker/init.d/03-nginx.sh`
- `rootfs/usr/local/etc/docker/init.d/04-php-fpm.sh`
- `rootfs/usr/local/etc/docker/init.d/02-named.sh` (replaced by `99-named.sh`)
- `rootfs/tmp/etc/nginx/` (entire dir)
- `rootfs/tmp/etc/php/` (entire dir)
- `rootfs/tmp/etc/tor/` (entire dir)
## Dockerfile changes
Surgical edits:
- `BUILD_DATE="202605101200"` (today, 2026-05-10).
- `SERVICE_PORT="53"` (was `"80"` — fixes the EXPOSE so DNS port is the primary advertised one).
- `EXPOSE_PORTS="53/udp"` (was `"53/tcp 53/udp"` — `SERVICE_PORT` is already 53/tcp via `EXPOSE ${SERVICE_PORT}`; we only need to add the udp variant).
- `PHP_VERSION="none"` (was `"php82"` — no PHP).
- `PACK_LIST="bind bind-tools bind-dnssec-root bind-plugins bash "` (was the multi-service list; trailing space preserved per template convention).
- Fix the upstream gen-dockerfile bug `[ "$SH_CMD" != "/bin/sh"]` → `[ "$SH_CMD" != "/bin/sh" ]` (missing space).
## .env.scripts changes
- `SERVICE_PORT="53"`.
- `EXPOSE_PORTS="53/udp"`.
- `PHP_VERSION="none"`.
- `ENV_PACKAGES="bind bind-tools bind-dnssec-root bind-plugins bash"` (mirrors PACK_LIST minus trailing space, single-space separated).
## Verification (success criteria)
1. `cd /root/Projects/github/casjaysdevdocker/bind && rm -f .build_failed && buildx run Dockerfile` succeeds for both `linux/amd64` and `linux/arm64`.
2. `docker run -d --rm --name test-bind -p 15353:53/udp -p 15353:53/tcp docker.io/casjaysdevdocker/bind:latest` boots; after ~25s `docker ps --filter name=test-bind --format '{{.Status}}'` shows `Up ... (healthy)` (healthcheck framework returns OK once init.d PID files exist).
3. `docker exec test-bind sh -c 'netstat -tnlp 2>/dev/null; netstat -unlp 2>/dev/null'` shows `named` (or `/usr/sbin/named`) bound to `0.0.0.0:53` on both tcp and udp.
4. `dig @127.0.0.1 -p 15353 +short . NS` (host-side, with `bind-tools`/`dnsutils` installed) returns the 13 root nameservers (recursion path through forwarders works).
5. `dig @127.0.0.1 -p 15353 +short google.com A` returns at least one A record.
6. `docker exec test-bind ls /config/bind/ /data/bind/` confirms `/config/bind/` (named.conf, secrets/, keys/) and `/data/bind/` (zones/, primary/, secondary/, stats/) are seeded.
7. `docker logs test-bind 2>&1 | tail -30` shows no FATAL or "exiting" errors; `named-checkconf -z` passed.
8. `docker stop test-bind`.
## Rollback
Code changes can be reverted via `git checkout -- rootfs/ Dockerfile .env.scripts`. New files (PLAN.md, CLAUDE.md, 99-named.sh) tracked separately. The deleted init.d scripts (01-tor.sh, 03-nginx.sh, 04-php-fpm.sh) and tmp/etc/{nginx,php,tor}/ remain in git history.
