Found while build-testing the freshly regenerated image in a temp data/config dir: opengist served REPLACE_HOSTNAME literally in every generated URL, and http.git-enabled routes redirected to bogus paths, because __update_conf_files() was patching a config file ($ETC_DIR/opengist.yaml) that doesn't exist -- the shipped config is named config.yaml. Also normalized the substituted value: opengist's external-url must be a full URL (scheme+host), not a bare hostname, or it breaks absolute-URL/redirect generation; ssh.external-domain must stay a bare domain, so it now gets its own REPLACE_SSH_HOSTNAME token instead of reusing the schemed value. Verified via: docker build, then a container run against a scratch temp dir with data/config volumes -- health check reports healthy, config.yaml shows the correct external-url/ssh.external-domain, and /-/all, /-/login, /-/register all return 200 with real opengist HTML. - rootfs/usr/local/etc/docker/init.d/00-opengist.sh: __update_conf_files now targets $ETC_DIR/config.yaml (was opengist.yaml, a nonexistent file), prefixes sysname with http:// when no scheme is present for external-url, and replaces ssh.external-domain via a separate REPLACE_SSH_HOSTNAME token using the unschemed hostname - rootfs/tmp/etc/opengist/config.yaml: ssh.external-domain placeholder changed from REPLACE_HOSTNAME to REPLACE_SSH_HOSTNAME
opengist
A containerized OpenGist — a self-hosted pastebin powered by Git. Create, share, and fork code snippets with full Git history, HTTP clone, SSH push/pull, and OAuth2 login via GitHub, GitLab, Gitea, or OpenID Connect. Built on Alpine Linux with SQLite storage and no external database required.
📦 Install
Via dockermgr (recommended)
sudo bash -c "$(curl -q -LSsf "https://github.com/systemmgr/installer/raw/main/install.sh")"
sudo systemmgr --config && sudo systemmgr install scripts
dockermgr update opengist

HOSTNAME |
casjaysdev-opengist |
Sets the external-url in opengist config |
SERVER_NAME / FULL_DOMAIN_NAME |
— | Override hostname for external URL |

Runtime config overrides
Place a shell script at /config/env/opengist.sh inside the container (or mount it as a file) to override any variable at runtime without rebuilding the image. A template is written on first start.
OAuth2
After first start, edit /config/opengist/config.yaml to add OAuth2 credentials:
github.client-key: <your-key>
github.secret: <your-secret>
gitlab.client-key: <your-key>
gitlab.secret: <your-secret>
gitlab.url: https://gitlab.com/
gitea.client-key: <your-key>
gitea.secret: <your-secret>
gitea.url: https://your-gitea-instance/
oidc.client-key: <your-key>
oidc.secret: <your-secret>
oidc.discovery-url: https://auth.example.com/.well-known/openid-configuration
OAuth2 callback URLs must follow the pattern:
http://<opengist-url>/oauth/<github|gitlab|gitea|openid-connect>/callback
🛠️ Development
Prerequisites
- Docker with
buildxsupport git
Get source
git clone "https://github.com/casjaysdevdocker/opengist" \
"$HOME/Projects/github/casjaysdevdocker/opengist"
cd "$HOME/Projects/github/casjaysdevdocker/opengist"
Or via dockermgr:
dockermgr download src casjaysdevdocker/opengist
Build the image
buildx
The build downloads the latest OpenGist release binary from GitHub at build time and bundles it into the image.
