# lxc_create
Create and configure LXContainers defined in inventory
## Requirements
- Ansible:
- Collection `community.general` for LXC modules
- Python:
- Bindings for LXC
- External plugins:
- `lxc_ssh` connection plugin from https://github.com/andreasscherbaum/ansible-lxc-ssh/
## Role Variables
- Required
- `ssh_keys`: List of SSH keys for root
- Optional
- `list_of_lxc_hosts`: unset default is `groups.lxc_host` (inventory group "lxc_hosts")
- `root_password`: unset, default is `root`
- `service_username`: unset, if defined user will be created
- `service_password`: unset, default is same as `service_username`
- `service_ssh_keys`: unset, default is same as `ssh_keys` (for root)
## Dependencies
- Host must be prepared for LXContainers
## Example Playbook
- hosts:
- lxc_containers
roles:
- lxc_create
## License
AGPL3.0-or-later
