Functions

func AddManagementKubeconfigFlags

func AddManagementKubeconfigFlags(kubeconfig, kubecontext *string, flags *pflag.FlagSet)

Set kubeconfig path and context flags for the management cluster.

func AddMeshctlConfigFlags

func AddMeshctlConfigFlags(meshctlConfigPath *string, flags *pflag.FlagSet)

Set the meshctl config file path

func AddOutputFlag

func AddOutputFlag(cmd *cobra.Command, format *string)

augment the input cobra command with a flag specifying the output format, also add pre-run validation that the format string is valid

func BuildClient

func BuildClient(kubeConfigPath, kubeContext string) (client.Client, error)

func BuildClientConfigAndClientset

func BuildClientConfigAndClientset(kubeconfig, kubeContext string) (clientcmd.ClientConfig, *kubernetes.Clientset, error)

BuildClientConfigAndClientset creates a rest.Config and AppsClientset from the given kubeconfig path and Context.

func BuildClientset

func BuildClientset(kubeConfigPath, kubeContext string) (*kubernetes.Clientset, error)

func DefaultMeshctlConfigFilePath

func DefaultMeshctlConfigFilePath() (string, error)

return the default meshctl config filepath

func EnsureNamespace

func EnsureNamespace(ctx context.Context, kubeClient client.Client, namespace string) error

func GetGlooMeshVersion

func GetGlooMeshVersion(ctx context.Context, kubeConfigPath, kubeContext, namespace string) (string, error)

func MarshalProtoWithFormat

func MarshalProtoWithFormat(msg proto.Message, format string) (string, error)

marshal a proto message with the given format

func PortForwardFromDeployment

func PortForwardFromDeployment(
	ctx context.Context,
	kubeConfig string,
	kubeContext string,
	deployName string,
	deployNamespace string,
	localPort string,
	remotePort string,
) (string, error)

Open a port-forward against the specified deployment. Returns the local port. If localPort is unspecified, a free port will be chosen at random. Canceling the context will stop the port-forward.

func PortForwardFromPod

func PortForwardFromPod(
	ctx context.Context,
	kubeConfig string,
	kubeContext string,
	podName string,
	podNamespace string,
	localPort string,
	remotePort string,
) (string, error)

Open a port forward against the specified pod. Returns the stop channel and the local port. If localPort is unspecified, a free port will be chosen at random. Close the port forward by closing the returned channel.

func RunShell

func RunShell(c string, writer io.Writer)

func UpdateMeshctlConfigWithDeregistrationInfo

func UpdateMeshctlConfigWithDeregistrationInfo(mgmtKubeConfigPath, mgmtKubecontext,
	remoteClusterName, remoteKubeConfigPath string) error

func UpdateMeshctlConfigWithInstallInfo

func UpdateMeshctlConfigWithInstallInfo(mgmtKubeConfig, mgmtKubecontext string) error

update the default meschtl config file with install info

func UpdateMeshctlConfigWithRegistrationInfo

func UpdateMeshctlConfigWithRegistrationInfo(mgmtKubeConfigPath, mgmtKubecontext,
	remoteClusterName, remoteKubeConfigPath, remoteKubecontext string) error

update the default meschtl config file with registration info

func WriteConfigToFile

func WriteConfigToFile(config MeshctlConfig, meshctlConfigPath string) error

func Zip

func Zip(fs afero.Fs, dir string, file string) error
