Functions

func AddHelmRepoIfMissing added in v1.3.1110 

func AddHelmRepoIfMissing(helmURL, repoName, username, password string, helmer Helmer,
	vaultClient vault.Client) (string, error)

AddHelmRepoIfMissing will add the helm repo if there is no helm repo with that url present. It will generate the repoName from the url (using the host name) if the repoName is empty. The repo name may have a suffix added in order to prevent name collisions, and is returned for this reason. The username and password will be stored in vault for the URL (if vault is enabled).
