install ansible

$ sudo apt install -y virtualenv build-essential python-dev libffi-dev libssl-dev $ mkdir env01 $ cd env01/ $ virtualenv venv $ source venv/bin/activate $ pip install git+https://github.com/ansible/ansible $ ansible --version ansible 2.4.0

ansible.cfg

$ cat ansible.cfg [defaults] inventory = hosts

hosts

$ cat hosts [mycontainer] f-cent01 ansible_connection=lxd f-cent02 ansible_connection=lxd

two containers are running

$ lxc list f- -cn4 +----------+--------------------+ |   NAME   |        IPV4        | +----------+--------------------+ | f-cent01 | 10.0.105.33 (eth0) | +----------+--------------------+ | f-cent02 | 10.0.105.89 (eth0) | +----------+--------------------+

run playbook

$ ansible-playbook restart.yml

- delete a container

$ cat delete_container.yml --- - hosts: localhost  connection: local  tasks:    - name: delete a container      lxd_container:        name: f-cent02        state: absent

- create containers

$ cat create-container.yml --- - hosts: localhost  connection: local  tasks:    - name: Create a started container      lxd_container:        name: my-container01        state: started   source:        type: image        mode: pull        server: https://images.linuxcontainers.org        protocol: lxd        alias: centos/7/amd64        profiles: ["default"]        wait_for_ipv4_addresses: true        timeout: 600

$ ansible-playbook create-container.yml

$ lxc list my-container01 +----------------+---------+------+------+------------+-----------+ |      NAME      |  STATE  | IPV4 | IPV6 |    TYPE    | SNAPSHOTS | +----------------+---------+------+------+------------+-----------+ | my-container01 | RUNNING |      |      | PERSISTENT | 0         | +----------------+---------+------+------+------------+-----------+

- create a container and install some packages via yum

$ ansible-playbook create-container-install.yml

$ lxc exec f-test01 -- ls /tmp/ hosts
