Functions

func AddCredentialsSecret added in v4.46.0 

func AddCredentialsSecret(comp InfoGetter, svc *runtime.ServiceRuntime, fieldList []string, allowDeletion bool, opts ...CredentialSecretOption) (string, error)

AddCredentialsSecret creates secrets and passwords for use with helm based services. This is to avoid issues with re-generating passwords if helm internal password generators are used. The function accepts a list of fields that should be populated with passwords. It returns the name of the secret resource, so it can be referenced later. The name of the inner secret object is the same as the resource name. Additionally it exposes the generated passwords as connection details, for easier retrieval.

func AddGenericSecret added in v4.73.0 

func AddGenericSecret(comp InfoGetter, svc *runtime.ServiceRuntime, suffix string, fieldList []string, allowDeletion bool, opts ...CredentialSecretOption) (string, error)

AddGenericSecret generates passwords the same way AddCredentialsSecret does. With the difference that the resource name can be chosen. This is helpful if multiple different random generated passwords are necessary.

func AddLoadbalancerNetpolicy added in v4.122.0
