When any non-global-flag parameter appears on the command line make sure there's a "command" even in the 'start' (run) case to ensure its not ambiguous as to what the arg is. For example, w/o this fix its not clear if runc foo means 'foo' is the name of a config file or an unknown command. Or worse, you can't name a config file the same a ANY command, even future (yet to be created) commands. We should fix this now before we ship 1.0 and are forced to support this ambiguous case for a long time. Signed-off-by: Doug Davis <dug@us.ibm.com>

|
|
|
|
runc is a command line client for running applications packaged according to
|
|
the Open Container Format (OCF) and is a compliant implementation of the
|
|
Open Container Initiative specification.
|
|
|
|
runc integrates well with existing process supervisors to provide a production
|
|
container runtime environment for applications. It can be used with your
|
|
existing process monitoring tools and the container will be spawned as a
|
|
direct child of the process supervisor.
|
|
|
|
After creating a spec for your root filesystem with runc, you can execute a
|
|
container in your shell by running:
|
|
|
|
cd /mycontainer
|
|
runc start
|
|
|
|
or
|
|
cd /mycontainer
|
|
runc start [ spec-file ]
|
|
|
|
If not specified, the default value for the 'spec-file' is 'config.json'. `
