- If trust_password is set, this module send a request for
authentication before sending any requests.
required: false
type: str
notes:
- Instances can be a container or a virtual machine, both of them must have unique name. If you attempt to create an instance
with a name that already existed in the users namespace the module will
simply return as "unchanged".
- There are two ways to run commands inside a container or virtual machine, using the command
module or using the ansible lxd connection plugin bundled in Ansible >=
2.1, the later requires python to be installed in the instance which can
be done with the command module.
- You can copy a file from the host to the instance
with the Ansible M(ansible.builtin.copy) and M(ansible.builtin.template) module
and the P(community.general.lxd#connection) connection plugin.
See the example below.
- You can copy a file in the created instance to the localhost
with C(command=lxc file pull instance_name/dir/filename filename).
See the first example below.
- linuxcontainers.org has phased out LXC/LXD support with March 2024
(U(https://discuss.linuxcontainers.org/t/important-notice-for-lxd-users-image-server/18479)).
Currently only Ubuntu is still providing images.
