wernight / docker-beroux-builder

Docker + docker-compose + kubectl to build and deploy projects on Kubernetes

Supported tags and respective Dockerfile links

• latest latest stable release
• 1, 1.8, 1.8.0 (or similar) are like latest but for a specific version of Kubernetes (kubectl).

Beroux-Builder

Bundle with almost minimal set of utilities to build Docker images and deploy them on Kubernetes:

• docker
• docker-compose
• kubectl
• envsubst

Also automatically creates a kubectl context using the service account if it detects there is one.

Usage

You should provide a Docker daemon either:

• Link a docker host pointing to docker:dind, or
• Mount host Docker socket /var/run/docker.sock, or
• Set DOCKER_HOST to where this container can reach a Docker daemon.

Example for GitLab CI

For example you can run GitLab CI with a .gitlab-ci.yml like:

build:
  stage: build
  image: wernight/beroux-builder
  services:
    - docker:dind
  before_script:
    - docker info
    - docker-compose version
    - docker login -u _json_key -p "$DOCKER_REGISTRY_TOKEN" https://eu.gcr.io
    - kubectl cluster-info
  script:
    - docker-compose build --pull
    - docker push my-repo/my-image
    - cat kubernetes.yml | envsubst | kubectl apply -f -

For this to work, you need:

• gitlab-ci-multi-runner set up in Docker mode with:
  • Environment variable DOCKER_REGISTRY_TOKEN set to access your Docker Registry (if private).
  • Kubernetes service account mounted (/var/run/secrets/kubernetes.io/serviceaccount/).
