Instance Method Details

#customize(key, value) ⇒ Object

Customize the container by calling ‘lxc-start` with the given configuration overrides.

For example, if you want to set the memory limit, you can use it like: config.customize ‘cgroup.memory.limit_in_bytes’, ‘400M’

When ‘lxc-start`ing the container, vagrant-lxc will pass in “-s lxc.cgroup.memory.limit_in_bytes=400M” to it.

Parameters:

  • key (String) —

    Configuration key to override

  • value (String) —

    Configuration value to override
