Just Commons

Universal Just command recipes for container management across projects.

Overview

This repository contains reusable Just recipes for:

• Container operations: start, stop, restart, logs, shell, exec, status
• Registry authentication: login, logout, status checks for GitHub Container Registry
• Image operations: build, push, pull, tag, test, info, clean
• Database operations: PostgreSQL and MySQL database management

Usage

Add as a Git submodule to your project:

git submodule add git@github.com:shadoll/just-commons.git

Import in your justfile:

# Import universal commands
import 'just-commons/core.just'        # Core utilities
import 'just-commons/container.just'   # Container operations
import 'just-commons/registry.just'    # Registry authentication
import 'just-commons/images.just'      # Image operations

# Import database and volume commands (optional)
import 'just-commons/postgres.just'    # PostgreSQL operations
import 'just-commons/mysql.just'       # MySQL operations
import 'just-commons/volumes.just'     # Volume management

Files

Core Files

• core.just - Core utilities (_detect_runtime, _detect_compose, env-check)
• container.just - Universal container operations (start, stop, logs, shell, exec, status)
• registry.just - GitHub Container Registry authentication (registry-login, registry-logout, registry-check)
• images.just - Universal image operations (image-build, image-push, image-pull, image-tag, etc.)

Database Files (Optional)

• postgres.just - PostgreSQL operations (postgres-sql, postgres-check, postgres-list-databases, etc.)
• mysql.just - MySQL operations (mysql-sql, mysql-check, mysql-list-databases, etc.)

Volume Management (Optional)

• volumes.just - Volume operations (volumes-clean-all, volumes-remove, volumes-list, etc.)

Command Structure

• Container commands: No prefix (start, stop, logs, shell, exec, status, restart)
• All other commands: Prefixed by file type (image-, registry-, postgres-, mysql-)

Usage Examples

# Container operations (no prefix)
just start postgres
just logs postgres
just shell postgres

# Image operations (image- prefix)
just image-build postgres
just image-push postgres v1.0.0

# Registry operations (registry- prefix)
just registry-login
just registry-check

# Database operations (database- prefix)
just postgres-sql "SELECT version();"
just postgres-check
just mysql-sql "SELECT VERSION();"

# Volume operations (volumes- prefix)
just volumes-list "myproject_*"
just volumes-clean-all
just volumes-remove "old_volume"
