# CI/CD Component
|
|
|
|
The CI/CD Component has some inputs which configure defaults for Nix GitLab CI.
|
|
|
|
## `version`
|
|
|
|
- Type: `string`
|
|
|
|
Which version of the Nix CI image to use. Using a tag/version is recommended.
|
|
Will not do anything if a custom image is specified using `NIX_CI_IMAGE`.
|
|
|
|
## `cache_strategy`
|
|
|
|
- Type: `string`
|
|
- Default: `"auto"`
|
|
- Options: `auto` | `none` | `runner` | `cachix` | `attic`
|
|
|
|
Sets the default caching strategy.
|
|
|
|
- `auto`: dynamically selects the best strategy for every job based on env variables
|
|
- `none`: disables caching
|
|
- `runner`, `cachix` & `attic`: forces every job to use this strategy
|
|
|
|
Can be overridden by `NIX_CI_CACHE_STRATEGY`, see [Environment Variables](./environment_variables.md).
|
|
|
|
## `cache_files`
|
|
|
|
- Type: `array` (of strings)
|
|
- Default: `["flake.nix", "flake.lock"]`
|
|
|
|
Files to use as the cache key for the generated pipeline yaml.
|
|
If you use a file like `ci.nix` to define CI, add that here for example.
|
|
This makes sure that changes to your Nix CI configuration will invalidate the cache,
|
|
otherwise an old pipeline yaml might be used.
|
|
|
|
!!! warning
|
|
|
|
The value of this is used in `cache:key:files`, which currently only supports
|
|
a max of 2 entries. So use something like `["flake.*", "ci.nix"]` to match
|
|
`flake.lock`, `flake.nix` and `ci.nix`.
