DP-9370 - use cc-service-bot to manage Semaphore project

[cchristous]

Background

Currently, some existing Semaphore projects were created manually via the Semaphore UI.
cc-service-bot is a tool for managing Semaphore projects via code (amongst other things).
Refer to the user guide for more information.
The DevProd team is migrating all Semaphore projects, which are not currently managed by cc-service-bot, to be managed by cc-service-bot.

• Service YAML file, service.yml

Rationales for argument values

The configuration here was selected based upon the settings of the existing Semaphore project. This configuration matches the existing project where possible. If desired, you can change the configuration to match your team's other repos. It was decided that it was more likely that you would like to maintain the existing settings for a project than conform to other projects you may own. It was impossible to have a one size fits all approach that would work for the migration tooling because different teams want different things.

• lang and lang_version are set to unknown because they are required by cc-service-bot. However, they are not used in this use case. They would only be used if you had pipeline_enable: true (or omitted it). In that case, these arguments would be passed to sem-version in the .semaphore/semaphore.yml file.
• git.enable is set to true because it results in the generated Semaphore project configuration to be committed to the repo under .semaphore/project.yml. Whether this is enabled or not, the same project gets generated. Additionally, it implies to auto-commit changes rather than leaving them stashed for engineers to commit manually. This basically separates the various plugins' updates into logical commits instead of lumping them together into a single commit to parse. Docs:

  • https://github.com/confluentinc/cc-service-bot/blob/master/plugin_git.py#L4
• pipeline_enable is set to false because if it is set to true, then cc-service-bot will modify the .semaphore/semaphore.yml file to match the standard implementation. Since the existing project was implemented manually, it is assumed that this differs from the cc-service-bot design, and we wouldn't want to overwrite it.
• triggers is set based upon your existing project's settings. The default behavior for the cc-service-bot is ['branches', 'tags', 'pull_requests']. If that is what you would like for this project, then you should delete the triggers parameter.
• branches is set based upon your existing project's settings. The default behavior for the cc-service-bot is ['master', 'main', '/^v\\d+\\.\\d+\\.x$/']. If that is what you would like for this project, then you should delete the branches parameter. Note that [] means workflows are triggered for all branches.
