Git Question

Multiple Docker images in .gitlab-ci.yml

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?

Answer

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
