Functions ¶

func AppContext ¶

func AppContext(context *cli.Context) (gocontext.Context, gocontext.CancelFunc)

AppContext returns the context for a command. Should only be called once per command, near the start.

This will ensure the namespace is picked up and set the timeout, if one is defined.

func ForwardAllSignals ¶

func ForwardAllSignals(ctx gocontext.Context, task killer) chan os.Signal

ForwardAllSignals forwards signals

func GetResolver ¶

func GetResolver(ctx gocontext.Context, clicontext *cli.Context) (remotes.Resolver, error)

GetResolver prepares the resolver from the environment and options

func LabelArgs ¶

func LabelArgs(labelStrings []string) map[string]string

LabelArgs returns a map of label key,value pairs

func NewClient ¶

func NewClient(context *cli.Context) (*containerd.Client, gocontext.Context, gocontext.CancelFunc, error)

NewClient returns a new containerd client

func ObjectWithLabelArgs ¶

func ObjectWithLabelArgs(clicontext *cli.Context) (string, map[string]string)

ObjectWithLabelArgs returns the first arg and a LabelArgs object

func ParseSignal ¶

func ParseSignal(rawSignal string) (syscall.Signal, error)

ParseSignal parses a given string into a syscall.Signal it checks that the signal exists in the platform-appropriate signalMap

func PrintAsJSON ¶

func PrintAsJSON(x interface{})
