func DeleteEtcdCluster

func DeleteEtcdCluster(etcdCRCli etcdCRClient.Interface, v *api.VaultService) error

DeleteEtcdCluster deletes the etcd cluster for the given vault

func DeployEtcdCluster

func DeployEtcdCluster(etcdCRCli etcdCRClient.Interface, v *api.VaultService) error

DeployEtcdCluster creates an etcd cluster for the given vault's name via etcd operator and waits for all of its members to be ready.

func DeployVault

func DeployVault(kubecli kubernetes.Interface, v *api.VaultService) error

DeployVault deploys a vault service. DeployVault is a multi-steps process. It creates the deployment, the service and other related Kubernetes objects for Vault. Any intermediate step can fail.

func EtcdNameForVault

func EtcdNameForVault(name string) string

EtcdNameForVault returns the etcd cluster's name for the given vault's name

func EtcdPeerTLSSecretName

func EtcdPeerTLSSecretName(vaultName string) string

EtcdPeerTLSSecretName returns the name of etcd peer TLS secret for the given vault name

func EtcdServerTLSSecretName

func EtcdServerTLSSecretName(vaultName string) string
