Functions

func FindHelmReleaseContainers 

func FindHelmReleaseContainers(annotations map[string]string, values map[string]interface{},
	visit func(string, image.Ref, ImageSetter) error)

FindHelmReleaseContainers examines the Values from a HelmRelease (manifest, or cluster resource, or otherwise) and calls visit with each container name and image it finds, as well as procedure for changing the image value.

func Load 

func Load(base string, paths []string) (map[string]KubeManifest, error)

Load takes paths to directories or files, and creates an object set based on the file(s) therein. Resources are named according to the file content, rather than the file name of directory structure.

func ParseMultidoc 

func ParseMultidoc(multidoc []byte, source string) (map[string]KubeManifest, error)

ParseMultidoc takes a dump of config (a multidoc YAML) and constructs an object set from the resources represented therein.

func PoliciesFromAnnotations 

func PoliciesFromAnnotations(annotations map[string]string) policy.Set

Types

type Args 

type Args []string

type ContainerImageMap 

type ContainerImageMap struct {
	BasePath   string
	Registry   string
	Repository string
	Tag        string
}

ContainerImageMap holds the YAML dot notation paths to a container image.

func (ContainerImageMap) AllDefined 

func (c ContainerImageMap) AllDefined() bool

AllDefined returns if all image elements are defined.

func (ContainerImageMap) GetRegistry 

func (c ContainerImageMap) GetRegistry() string

func (ContainerImageMap) GetRepository 

func (c ContainerImageMap) GetRepository() string

func (ContainerImageMap) MapImageRef 

func (c ContainerImageMap) MapImageRef(image image.Ref) (map[string]string, bool)

MapImageRef maps the given imageRef to the dot notation paths ContainerImageMap holds. It needs at least an Repository to be able to compose the map, and takes the absence of the registry and/or tag paths into account to ensure all image elements (registry, repository, tag) are present in the returned map.

func (ContainerImageMap) RegistryRepository 

func (c ContainerImageMap) RegistryRepository() bool

RegistryRepository returns if the registry and repository are defined, but the tag is not.

func (ContainerImageMap) RepositoryOnly
