Docker with docker-compose

Based on official docker, but with docker-compose tool (and few others, e.g. curl) installed inside.

Usage

When you want to keep CI builds identical to these on local developer machine, you probably will keep everything in docker-compose.yml, so the developer can easily do docker-compose build and docker-compose up without worrying about anything.

Then you want to use the same setup on CI environment. Here's how it could look like:

.gitlab-ci.yml:

my-build-job:
  image: docker22.bs.lan/docker/docker-compose:1.21.2
  script:
    - export DOCKER_IMAGE_NAME="docker22.bs.lan/blackswan/fe-project-name:v${CI_PIPELINE_ID}"
    - docker-compose build

And example docker-compose.yml might look like this:

version: '3'
services:
  fe-project-name:
#    image: docker22.bs.lan/blackswan/fe-project-name:v43
    image: ${DOCKER_IMAGE_NAME:-fe-project-name} # Use env set in CI - or fallback to default
    build:
      context: .
      dockerfile: scripts/docker/Dockerfile
    ports:
      - '4780:80' # export the app locally on :port
