This manager parses [Flux](https://fluxcd.io/) YAML manifests and supports:
|
|
|
|
1. [`HelmRelease`](https://fluxcd.io/docs/components/helm/helmreleases/) resources
|
|
1. [`GitRepository`](https://fluxcd.io/flux/components/source/gitrepositories/) resources
|
|
1. [`OCIRepository`](https://fluxcd.io/flux/components/source/ocirepositories/) resources
|
|
1. Flux [system](https://fluxcd.io/docs/installation) manifests
|
|
|
|
### HelmRelease support
|
|
|
|
Extracts `helm` dependencies from `HelmRelease` resources.
|
|
|
|
The `flux` manager extracts `helm` dependencies for `HelmRelease` resources linked to `HelmRepository` or `GitRepository` sources.
|
|
Renovate supports OCI `HelmRepository` sources, those with `type: oci`.
|
|
Renovate will then extract the `docker` dependencies for the referenced `HelmRelease` resources.
|
|
|
|
In addition, for the `flux` manager to properly link `HelmRelease` and `HelmRepository` resources, _both_ of the following conditions must be met:
|
|
|
|
1. The `HelmRelease` resource must either have its `metadata.namespace` property set or its `spec.chart.spec.sourceRef.namespace` property set
|
|
2. The referenced `HelmRepository` resource must have its `metadata.namespace` property set
|
|
|
|
Namespaces will not be inferred from the context (e.g. from the parent `Kustomization`).
|
|
|
|
Renovate updates `HelmRelease` resources coming from `GitRepository` by updating the `GitRepository` resource.
|
|
|
|
### GitRepository support
|
|
|
|
Renovate can update `git` references from `GitRepository` resources.
|
|
|
|
The `flux` manager only updates `GitRepository` fields that have a `tag` or `commit` key.
|
|
|
|
### Kustomization support
|
|
|
|
Renovate can update `image`[^1] references from `Kustomization` resources.
|
|
|
|
### OCIRepository support
|
|
|
|
Renovate can update `oci` references from `OCIRepository` resources.
|
|
|
|
The `flux` manager only updates `OCIRepository` fields that have a `digest` or `tag` key.
|
|
If `tag` _and_ `digest` exist then `digest` takes precedence.
|
|
|
|
### Flux system manifests support
|
|
|
|
Renovate supports updating Flux system manifests generated during [Flux installation](https://fluxcd.io/docs/installation/#customize-flux-manifests).
|
|
System manifests are identified via being named `gotk-components.y(a)ml` and containing comment headers as generated by `flux bootstrap`.
|
|
|
|
<!-- prettier-ignore -->
|
|
!!! warning
|
|
Renovate cannot identify the use of custom bootstrap flags, such as `--cluster-domain`.
|
|
In such a scenario Renovate's PR will overwrite these values with the Flux defaults.
|
|
See [issue #13952 on GitHub](https://github.com/renovatebot/renovate/issues/13952) for more information.
|
|
|
|
Updating system manifests requires that either:
|
|
|
|
1. The `flux` tool is pre-installed, or
|
|
1. You run a Docker image based on [containerbase](https://github.com/containerbase), such as the official Renovate images, and have `binarySource=install` configured
|
|
|
|
### Default fileMatch
|
|
|
|
By default, the `flux` manager only matches `**/gotk-components.y(a)ml`.
|
|
So it only checks system manifest files generated by the `flux bootstrap` command.
|
|
|
|
This is because there is no commonly accepted file/directory naming convention for Flux manifests and we don't want to check every single `*.yaml` file in repositories just in case some of them have Flux definitions.
|
|
|
|
If most `.yaml` files in your repository are Flux manifests, then you could add this to your config:
|
|
|
|
```json
|
|
{
|
|
"flux": {
|
|
"fileMatch": ["\\.yaml$"]
|
|
}
|
|
}
|
|
```
|
|
|
|
If instead you have all your Flux manifests inside a `flux/` directory, you would add this:
|
|
|
|
```json
|
|
{
|
|
"flux": {
|
|
"fileMatch": ["flux/.+\\.yaml$"]
|
|
}
|
|
}
|
|
```
|
|
|
|
### Versioning
|
|
|
|
If you need to change the versioning format, read the [versioning](../../versioning/index.md) documentation to learn more.
