docker
GitLab provides service called dind
BUT! No docker-compose built-in!
Custom-Image for docker-compose
Registry for passing images through stages
GitLab provides a docker registry
FROM jonaskello/docker-and-compose:17.03.0-1.11.2
RUN apk add --update make
custom image for docker-compose
image: registry.gitlab.com/tradebyte/build-image:latest
services:
- docker:dind
stages:
- build
- test
before_script:
- docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
build:
stage: build
script:
- docker-compose build py
- docker-compose push py
- docker images
lint:
stage: test
script:
- docker-compose pull py
- docker images
- make lint
passing image via gitlab registry
cross dependencies
GitLab provides Secret Keys in CI settings
GitLab provides Deploy-Keys to read a repository
Configure Deploy-Key in dependency
Configure Secrets in dependent project(s)
configure deploy-key in dependency
configure secrets in dependent projects
Single button deployment
Again Secrets in GitLab CI
Own repository for deployment, checked out on live
Our basic workflow with gitlab ci
$ git push origin feature/dvocc17...
