"""This tool can be used to set up a base container for test. For example,
|
||
|
|
python lxc.py -s -p /tmp/container
|
||
|
|
This command will download and setup base container in directory /tmp/container.
|
||
|
|
After that command finishes, you can run lxc command to work with the base
|
||
|
|
container, e.g.,
|
||
|
|
lxc-start -P /tmp/container -n base -d
|
||
|
|
lxc-attach -P /tmp/container -n base
