Repository source

You'll find the Operations repository at https://devcentral.nasqueron.org/source/operations/

If DevCentral isn't available, a mirror of the repository can be found at https://github.com/nasqueron/operations.

Workflow of contributions

We follow the general workflow is described at How to contribute code.

Before committing a change to the main branch, you can test a deployment on a server. In that case, merge in main immediately after the deployment as the repository is the source of truth for the server state.

Log what you do on #nasqueron-ops, so it will be included at https://infra.nasqueron.org/servers-log/

Code conventions

  • Python code: run `black` before committing
  • YAML: indent with two spaces, including list bullets
id:
  method:
    - somekey: value
    - otherkey: value

IDE configuration

Screenshot of correctly configured template languages

The states .sls file are Jinja2 templates producing YAML files, or "jinja2+yaml". If this case can't be handled by your IDE, it works best to use YAML syntax highlighting.

If you use PyCharm or IntelliJ IDEA Ultimate, you can configure this scheme:

  • Allow YAML files to be Jinja2 templates
    • Go to Settings > Languages & Frameworks > Template Languages
    • Select Jinja2 as template language
    • Add YAML in the list
  • Open SLS as YAML
