How can I use GitLab runner to ensure effective CI/CD operations?

Here is the example given in order to ensure effective CI/CD operations by using the “GitLab runner” or “gitlab-ci.yml” file. Here is the structure following:-

Stages:

  - test

  - build

  - deploy

# Define jobs for each stage

Test:

  Stage: test

  Script:

# Your testing commands here

Build:

  Stage: build

  Script:

# Your build commands here

  Artifacts:

    Paths:

# Define build artifacts to be stored

Deploy:

  Stage: deploy

  Script:

# Your deployment commands here

  Only:

Master # Example: deploy only on the master branch

GitLab Runner Configuration

Multiple Runners:- You can install and register to the multiple GitLab runners. 

Runner tags:- Assign the tags to the runners. It should be based on their capabilities.

Runner registration:- Register the each runner by using the command

“GitLab- runner register – name  -- url  -- registration-token  -- tag-list “, ”

Run the configuration file by using:-

[[runners]]

  Name = “Runner1”

  url = https://gitlab.com/

  token = “your_token”

  executor = “shell”

  [runners.custom_build_dir]

  [runners.cache]

    [runners.cache.s3]

    [runners.cache.gcs]

  [runners.docker]

    Tls_verify = false

    Image = “alpine”

    Privileged = false

    Disable_entrypoint_overwrite = false

    Oom_kill_disable = false

    Disable_cache = false

    Volumes = [“/cache”]

    Shm_size = 0

Parallel execution:- You can set up the parallel execution of the job by using:-

Test:

  Stage: test

  Script:

# Your testing commands here

Parallel: 5 # Example: Run 5 jobs in parallel By combining all these YAML files and Gitlab runners you can easily optimize your CI/CD pipeline to handle branches.
