Constants

const LayerAnnotation = "weave.works/layer"

LayerAnnotation specifies profile application order. Profiles are sorted by layer and those at a higher "layer" are only installed after lower layers have successfully installed and started.

const ProfileAnnotation = "weave.works/profile"

ProfileAnnotation is the annotation that Helm charts must have to indicate that they provide a Profile.

Variables

var Profiles = func(v *repo.ChartVersion) bool {
	return hasAnnotation(v.Metadata, ProfileAnnotation)
}

Profiles is a predicate for scanning charts with the ProfileAnnotation.

type ChartReference

type ChartReference struct {
	Chart   string
	Version string
}

ChartReference is a Helm chart reference

type HelmRepoManager interface {
	ListCharts(ctx context.Context, hr *sourcev1beta1.HelmRepository, pred ChartPredicate) ([]*pb.Profile, error)
	GetValuesFile(ctx context.Context, helmRepo *sourcev1beta1.HelmRepository, c *ChartReference, filename string) ([]byte, error)
}

type RepoManager

type RepoManager struct {
	client.Client
	CacheDir string
	// contains filtered or unexported fields
}
