Docker Image Mirror

This repository (loftwah/buildkit) mirrors Docker images to the GitHub Container Registry (GHCR) with precision and reliability, giving you fast access to key tools. Two workflows keep everything up to date:

• Daily Mirror: Syncs latest tags every day for buildkit, ruby, nginx, and node, with an option to manually sync a specific version.
• All Versions Mirror: Manually fetches the latest versions plus two recent stable ones for all four images with a single click.

Here's what gets mirrored:

• moby/buildkit → ghcr.io/loftwah/buildkit/buildkit
• ruby → ghcr.io/loftwah/buildkit/ruby
• nginx → ghcr.io/loftwah/buildkit/nginx
• node → ghcr.io/loftwah/buildkit/node

Pulling the Images

You'll need Docker installed (download it from docker.com if you don't have it). Open a terminal and use these commands to pull the latest versions, which are always available after the daily run:

docker pull ghcr.io/loftwah/buildkit/buildkit:latest  # BuildKit
docker pull ghcr.io/loftwah/buildkit/ruby:latest      # Ruby
docker pull ghcr.io/loftwah/buildkit/nginx:latest     # Nginx
docker pull ghcr.io/loftwah/buildkit/node:latest      # Node.js

Specific Versions

• Daily Workflow: Automatically mirrors latest tags daily. For a specific version (e.g., ruby:3.3.0), use the manual trigger option below.
• All Versions Workflow: Pulls the latest version plus two prior stable ones when triggered manually. As of March 2024, typical versions might include:
  • BuildKit: v0.13.0 (latest), v0.12.5, v0.12.0
  • Ruby: 3.3.0 (latest), 3.2.3, 3.2.2
  • Nginx: 1.25.4 (latest), 1.24.0, 1.23.4
  • Node: 21.7.1 (latest), 20.11.1, 18.19.1

To pull a specific version:

docker pull ghcr.io/loftwah/buildkit/ruby:3.3.0

If you get a "manifest unknown" error, it hasn't been mirrored yet—run the appropriate workflow first.

Using the Images

Here's how to use them after pulling:

BuildKit

For building Docker images efficiently. Start it:

docker run -d --name buildkitd --privileged ghcr.io/loftwah/buildkit/buildkit:latest

Then build a project:

docker buildx create --use --name mybuilder --driver remote tcp://localhost:1234
docker buildx build -t myimage:latest .

Ruby

For running Ruby applications. Start it:

docker run -it ghcr.io/loftwah/buildkit/ruby:latest bash

Inside, run:

ruby -e 'puts "Ruby is ready to roll!"'

Nginx

For hosting a web server. Start it:

docker run -d -p 80:80 ghcr.io/loftwah/buildkit/nginx:latest

Open http://localhost in your browser to see Nginx in action.

Node.js

For JavaScript development. Start it:

docker run -it ghcr.io/loftwah/buildkit/node:latest bash

Inside, run:

node -e 'console.log("Node.js is up and running");'

Workflows

Daily Mirror (mirror-images.yml)

• Runs: Automatically every day at midnight UTC (12:00 AM universal time).
• Purpose: Keeps latest tags up to date for all images.
• Manual Override: Can sync a specific image version via workflow dispatch.

All Versions Mirror (mirror-all-images.yml)

• Runs: Manually triggered only.
• Purpose: Syncs latest version plus two prior stable versions for each image.
• Note: Use this when you need specific version tags.
