GitLab FI

GitLab Continuous Integration

GitLab Continuous Integration (CI) is used to automate some repository development tasks, most often for automated unit testing. For use with GitLab CI can be configure your own physical or virtual machine (see Stratus.FI virtualization ). In addition, a faculty machine can also be used gitlab-ci.fi.muni.cz .

Summary

Fakultní gitlab-ci.fi used official GitLab Runner with container insulation on duty Docker . After a new task has started (e.g. git push GitLab Runner asks Docker to create a new container from the image that is declared in the repository in the file .gitlab-ci.yml . The repository is cloned into the container and the tasks described in the file are started. When finished, the container is dropped and the result is returned to GitLab, which displays it in the CI / CD section.

Configuring the Project for gitlab-ci.fi.muni.cz

Read first introductory information for using GitLab CI / CD . Next you will need documentation .gitlab-ci.yml .

The docker is configured not to automatically install all required images, but to use only those locally available. This avoids over-installation of various versions of images that would quickly fill the disk capacity of the machine.

For a list of the images available for the GitLab CI faculty, see application of the Faculty Administration .

The image used is declared in .gitlab-ci.yml configuration as the key value image . The format is either REPOSITORY:TAG or REPOSITORY (the default tag is then used latest ). If no image is specified, it is used alpine:latest .

image: maven:latest

If possible, use images with a mark latest or at least the most general version (e.g. 3-jdk-8 place 3.5.0-jdk-8 ). In the case of image updates, older versions will be deleted if there is no free space on the disk.

The machine accepts tasks from repositories that have their own CI set gitlab-ci.fi tasks only from those projects that are marked with a mark shared-fi , which can be set as follows:

• in Settings → General → Permissions, enable the Pipelines option if it is not already enabled
• in settings .gitlab-ci.yml add a tag shared-fi to each goal, eg:

  build:
    tags:
      - shared-fi

In the faculty GitLab FI you can look into the project unix/ci-examples , where you will find CI configuration examples for simple projects.

Installing additional images

Ask to install additional images or versions at unix@fi.muni.cz , specifying what the image will be used for.

If you want to install your own or customized image, please also include the application Dockerfile and all the necessary files to build the image. Administrators build and install the image into Docker.
