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.

⚙️ Configuration

Volumes

Path	Purpose
/config	Runtime configuration (auto-generated on first start)
/data	Gist repositories, SQLite database, logs, and index

Ports

Port	Protocol	Purpose
80	HTTP	Web UI and HTTP Git clone/pull
7823	TCP	Built-in SSH server for Git push/pull

Environment variables

Variable	Default	Description
TZ	America/New_York	Container timezone
HOSTNAME	casjaysdev-opengist	Sets the external-url in opengist config
SERVER_NAME / FULL_DOMAIN_NAME	—	Override hostname for external URL
OPENGIST_APPNAME_ENABLED	yes	Set to no to disable the service
OPENGIST_ROOT_USER_NAME	—	Initial admin username
OPENGIST_ROOT_PASS_WORD	—	Initial admin password
OPENGIST_USER_NAME	—	Initial normal user name
OPENGIST_USER_PASS_WORD	—	Initial normal user password
DEBUGGER	—	Set to on to enable shell-level debug tracing

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 buildx support
• 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.
