Name: "delete",
|
|
Usage: "delete any resources held by the container often used with detached container",
|
|
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 runhcs list currently shows the
|
|
status of "ubuntu01" as "stopped" the following will delete resources held for
|
|
"ubuntu01" removing "ubuntu01" from the runhcs list of containers:
|
|
|
|
# runhcs delete ubuntu01`,
|
|
Flags: []cli.Flag{
|
|
cli.BoolFlag{
|
|
Name: "force, f",
|
|
Usage: "Forcibly deletes the container if it is still running (uses SIGKILL)",
|
|
},
|
|
},
|
|
Before: appargs.Validate(argID),
|
|
Action: func(context *cli.Context) error {
|
|
id := context.Args().First()
|
|
force := context.Bool("force")
