Part 1. Setting up the gitlab-runner

Start Ubuntu Server 22.04 LTS virtual machine.

Download and install gitlab-runner on the virtual machine.

Run gitlab-runner and register it for use in the current project (DO6CICD).

Part 2. Building

Write a stage for CI to build applications from the C2SimpleBashUtils project.

In the gitlab-ci.yml file, add a stage to start the building via makefile from the C2 project.

Save post-build files (artifacts) to a random directory with a 30-day retention period.

Part 3. Codestyle test

Write a stage for CI that runs a codestyle script (clang-format).

If the codefile didn't pass, "fail" the pipeline.

In the pipeline, display the output of the clang-format utility.

Part 4. Integration tests

Write a stage for CI that runs your integration tests from the same project.

Run this stage automatically only if the build and codestyle test passes successfully.

If tests didn't pass, "fail" the pipeline.

In the pipeline, display the output of the succeeded / failed integration tests.

Part 5. Deployment stage

Start the second virtual machine Ubuntu Server 22.04 LTS.

Write a stage for CD that "deploys" the project on another virtual machine.

Run this stage manually, if all the previous stages have passed successfully.

Write a bash script which copies the files received after the building (artifacts) into the /usr/local/bin directory of the second virtual machine using ssh and scp.

In the gitlab-ci.yml file, add a stage to run the script you have written.

In case of an error, fail the pipeline.

Save dumps of virtual machine images.

Part 6. Bonus. Notifications

Set up notifications of successful/unsuccessful pipeline execution via bot named "[your nickname] DO6 CI/CD" in Telegram.
