Chapter III

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 (*DO6_CICD*).

Part 2. Building

Write a stage for **CI** to build applications from the *C2_SimpleBashUtils* 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*.
