Functions ¶
func APIEnvVarsToMap ¶
V1EnvVarsToMap constructs a map of environment name to value from a slice of env vars.
func AddToEnvList ¶
Add an entry to the list of environment variables. Also removes duplicate entries, only keeping the last one.
func EnvironToAPIEnvVar ¶
func ExpandContainerCommandOnlyStatic ¶
func ExpandContainerCommandOnlyStatic(containerCommand []string, envs []api.EnvVar) (command []string)
ExpandContainerCommandOnlyStatic substitutes only static environment variable values from the container environment definitions. This does *not* include valueFrom substitutions. TODO: callers should use ExpandContainerCommandAndArgs with a fully resolved list of environment.
func GetNameFromString ¶
func GetNamespaceFromString ¶
func LookupUser ¶
func ParseImageSpec ¶
Most registry URLs don't have a leading scheme (e.g. http://). This means that we can't use url.Parse to find the host name from the image's path. We'll use some heuristics to get the server and image path.
func SetOOMScore ¶
We disable the OOM Killer for Itzo in the itzo startup script but we want to reenable it for user processes that itzo spawns
func SplitNamespaceAndName ¶
func WithNamespace ¶
Types ¶
type FakeUserLookup ¶
