Variables

View Source 
var ListDefaultLimit int64 = 512

ListDefaultLimit is the default limit for number of items returned in a list.

View Source 
var ValidName = regexp.MustCompile("^(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])+$")

ValidName is a regular expression for names.

According to the Kubernetes help text, the regular expression it uses is: 

(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?

We modified that. First, we added start and end delimiters. Second, we changed the final ? to + to require that the pattern match at least once. This modification prevents an empty string from matching.

Functions

func DefaultServerOpts 

func DefaultServerOpts() []grpc.ServerOption

DefaultServerOpts returns the set of default grpc ServerOption's that Tiller requires.

func DeleteRelease 

func DeleteRelease(rel *release.Release, vs chartutil.VersionSet, kubeClient environment.KubeClient) (kept string, errs []error)

DeleteRelease is a helper that allows Rudder to delete a release without exposing most of Tiller inner functions

func GetAllVersionSet 

func GetAllVersionSet(client discovery.ServerResourcesInterface) (chartutil.VersionSet, error)

GetAllVersionSet retrieves a set of available k8s API versions and objects

This is a different function from GetVersionSet because the signature changed. To keep compatibility through the public functions this needed to be a new function.GetAllVersionSet TODO(mattfarina): In Helm v3 merge with GetVersionSet

func GetVersionSet 

func GetVersionSet(client discovery.ServerGroupsInterface) (chartutil.VersionSet, error)

GetVersionSet retrieves a set of available k8s API versions

func NewServer 

func NewServer(opts ...grpc.ServerOption) *grpc.Server

NewServer creates a new grpc server.
