Errors

Functions

func FromEnv 

func FromEnv(ctx context.Context, cfg *Config) error

FromEnv initializes the provided configuration object with values obtained from environment variables. If an environment variable is set for a property that's already initialized, the environment variable's value takes precedence.

func FromEnvToGC 

func FromEnvToGC(ctx context.Context, cfg *Config) error

FromEnvToGC initializes the provided configuration object with values obtained from environment variables. If an environment variable is set for a property that's already initialized, the environment variable's value takes precedence.

func GetClusterFlavor 

func GetClusterFlavor(ctx context.Context) (cnstypes.CnsClusterFlavor, error)

GetClusterFlavor returns the cluster flavor based on the env variable set in the driver deployment file.

func GetSupervisorNamespace 

func GetSupervisorNamespace(ctx context.Context) (string, error)

GetSupervisorNamespace returns the supervisor namespace in which this guest cluster is deployed.
