* git\_branch | string

  Default: master

  The git branch to check out.
* git\_depth | int

  Default: 1

  Cloning depth, to truncate commit history to the specified number of commits. Zero means no truncating.
* git\_repo | string

  URL to repo to clone and sync against.
* git\_rev | string

  Default: HEAD

  The git revision (tag or hash) to check out
* git\_ssh\_key | string

  An optional SSH private key to use when cloning the repository.
  WARNING: This will expose your private key as cleartext in the Juju config. Use the
  "git\_ssh\_key\_secret" config option instead.
* git\_ssh\_key\_secret | string

  An optional SSH private key to use when cloning the repository.
  This option takes priority over "git\_ssh\_key" if both are set.
  The value must be a Juju secret ID, which references a Juju secret, containing the private SSH key. The format for the input is:

  + secret://<secret-id>/<key>

  This requires the admin to create a Juju secret. The secret must:

  + exist in the same model as the cos-configuration charm
  + have a key named <key> with the value of the private SSH key

  Make sure to "grant-secret" this secret to the cos-configuration charm.
* grafana\_dashboards\_path | string

  Default: grafana\_dashboards

  Relative path in repo to grafana dashboards.
* known\_hosts\_config | string

  Default: github.com ssh-rsa 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

  Contents for the SSH known\_hosts file used when cloning via SSH. Each line should follow the standard known\_hosts format (e.g. "hostname algorithm base64-key"). The remote extracted from git\_repo must appear in this value, otherwise the charm will block.
  The default includes public host keys for github.com and git.launchpad.net. To add another host (e.g. gitlab.com), run "ssh-keyscan gitlab.com" and append the output lines to this value.
* loki\_alert\_rules\_path | string

  Default: loki\_alert\_rules

  Relative path in repo to loki rules.
* prometheus\_alert\_rules\_path | string

  Default: prometheus\_alert\_rules

  Relative path in repo to prometheus rules.

  Default: slos

  Relative path in repo to SLO (Service Level Objective) files for sloth.
