Docker Cache Buildkite Plugin

A Buildkite plugin that lets you cache the contents of docker volumes.

⚠️ Requires an in-development version of the docker-compose buildkite plugin ⚠️

Example

docker-compose.yml:

version: "3.8"
services:
  rails:
    build: .
    volumes:
      - bundler-data:/usr/local/bundle

volumes:
  bundler-data:

pipeline.yml:

steps:
  - command: bundle install
    plugins:
      - docker-cache#v1.0.0:
          s3_bucket: my-cache-bucket
          keys:
            - v1-bundler-cache-{{ arch }}-{{ checksum "Gemfile.lock" }}
            - v1-bundler-cache-{{ arch }}
          save: true
          volumes:
            - bundler-data

      - docker-compose#v3.7.0:
          run: app

  - command: rspec spec
    plugins:
      - docker-cache#v1.0.0:
          s3_bucket: my-cache-bucket
          keys:

            - v1-bundler-cache-{{ arch }}
          volumes:
            - bundler-data
