Overview

Package action contains the logic for each action that Helm can perform.

This is a library for calling top-level Helm actions like 'install', 'upgrade', or 'list'. Actions approximately match the command line invocations that the Helm client uses.

Index

Constants

View Source 
const ListAll = ListDeployed | ListUninstalled | ListUninstalling | ListPendingInstall | ListPendingRollback | ListPendingUpgrade | ListSuperseded | ListFailed

ListAll is a convenience for enabling all list filters

Variables

View Source 
var Timestamper = time.Now

Timestamper is a function capable of producing a timestamp.Timestamper.

By default, this is a time.Time function from the Helm time package. This can be overridden for testing though, so that timestamps are predictable.

View Source 
var ValidName = regexp.MustCompile(`^[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*$`)

ValidName is a regular expression for resource names.

DEPRECATED: This will be removed in Helm 4, and is no longer used here. See pkg/lint/rules.validateMetadataNameFunc for the replacement.

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

[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*

This follows the above regular expression (but requires a full string match, not partial).

The Kubernetes documentation is here, though it is not entirely correct: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

Types

type ChartPathOptions
