Multiple Docker images in .gitlab-ci.yml

Question

Here is my problem setup with GitLab and its integrated CI service. I have a current GitLab 8.1. and a gitlabci-multi-runner (0.6.2) with Docker support. After extending the ubuntu:precise image to include git and build-essentials (now named precise:base) I got the following .gitlab-ci.yml running:

image: precise:base
before_script:
   - apt-get install --yes cmake libmatio-dev libblas-dev libsqlite3-dev libcurl4-openssl-dev
   - apt-get install --yes libarchive-dev liblzma-dev

build:
  script:
    - mkdir build/
    - cd build
    - cmake -D CMAKE_BUILD_TYPE=Debug ../
    - make

Now my question is how to include more jobs on different images? Because I need to check if the code compiles (and later on works) on different operating systems like Ubuntu Precise, Ubuntu Trusty, CentOS 6, CentOS 7. To reduce the work I think the best way is to provide different Docker images as base.

Now the questions is how must the .gitlab-ci.yml look like to support this?

have a look to extend keyword https://docs.gitlab.com/ee/ci/yaml/#extends — Ruggero Turra, Jul 09 '21 at 16:09

You can define the image to use per job.

For instance:

before_script:
   - apt-get install --yes cmake libmatio-dev libblas-dev libsqlite3-dev libcurl4-openssl-dev
   - apt-get install --yes libarchive-dev liblzma-dev

build:precise:
  image: precise:base
  script:
    - mkdir build/
    - cd build
    - cmake -D CMAKE_BUILD_TYPE=Debug ../
    - make

build:trusty:
  image: trusty:base
  script:
    - mkdir build/
    - cd build
    - cmake -D CMAKE_BUILD_TYPE=Debug ../
    - make

is there a way to define two images per job? I need a gradle:jdk11 image as well as a mysql image for a particular testing job – Hemil Feb 29 '20 at 12:10
@Hemil did you get a way to use 2 images ? – bucky barns May 31 '21 at 13:15
@buckybarns there is a way to use services in gitlab. So I can use one image for jdk add specify a service for mysql. Unfortunately, I have abandoned that project but you can find resources on how to add services in gitlab – Hemil Jun 01 '21 at 15:46
@Hemil i used a custom gitlab runner instead. Since I had a lot of configurations to be added on gitlab runner. – bucky barns Jun 02 '21 at 11:32

Your can use Anchors to make the .gitlab-ci.yml more clearly. (But this need GitLab 8.6 and GitLab Runner v1.1.1.)

Like this:

before_script:
   - apt-get install --yes cmake libmatio-dev libblas-dev libsqlite3-dev libcurl4-openssl-dev
   - apt-get install --yes libarchive-dev liblzma-dev

.build_template: &build_definition
  script:
    - mkdir build/
    - cd build
    - cmake -D CMAKE_BUILD_TYPE=Debug ../
    - make

build:precise:
  image: precise:base
  <<: *build_definition

build:trusty:
  image: trusty:base
  <<: *build_definition

Thank you for this answer, this is exactly what I'm searching for. Awesome! — codegorilla, May 05 '22 at 11:40
