var deleteCommand = cli.Command{

Name: "delete",
|
|
Usage: "delete any resources held by the container often used with detached containers",
|
|
ArgsUsage: `<container-id>
|
|
|
|
Where "<container-id>" is the name for the instance of the container.

|
EXAMPLE:
|
|
For example, if the container id is "ubuntu01" and runc list currently shows the
|
|
status of "ubuntu01" as "destroyed" the following will delete resources held for
|
|
"ubuntu01" removing "ubuntu01" from the runc list of containers:
|
|
|
|
# runc delete ubuntu01`,
|
|
Action: func(context *cli.Context) error {
|
|
container, err := getContainer(context)
|
|
if err != nil {
|
|
if lerr, ok := err.(libcontainer.Error); ok && lerr.Code() == libcontainer.ContainerNotExists {
|
|
// if there was an aborted start or something of the sort then the container's directory could exist but
|
|
// libcontainer does not see it because the state.json file inside that directory was never created.
