Ansible LXD Provisioning | About

Containerization has changed the way we deploy and manage applications.

Ansible, combined with LXD, offers a solution for container provisioning.

Today, we will take a look at how to provision LXD containers using Ansible

1. To begin with, we have to install Ansible on our control machine. We can use package managers like apt, yum, or brew, depending on our OS.

   # Example for Ubuntu/Debian
sudo apt-get install ansible

2. Then, we have to install the Python package on our Ansible control machine:

   pip install pylxd
3. Now, make sure LXD is installed on the machine where we plan to provision containers. We can use the package manager specific to our Linux distribution to install LXD:

   
# Example for Ubuntu/Debian
sudo apt-get install lxd

   Additionally, we have to configure LXD like setting up a storage pool, configuring networks, and initializing LXD.
4. At this point, we have to make sure the Ansible control machine has access to the LXD daemon. This involves configuring LXD to listen on a network interface and setting up a client certificate:

   # Example: Configure LXD to listen on the network
sudo lxc config set core.https_address "[::]:8443"

5. Now it is time to create Ansible playbooks and roles to define tasks for LXD provisioning. Tasks can include creating containers, configuring container properties, installing software, and managing container state.

   For example, here is a playbook (provision_lxd_container.yml):

   ---
- name: Provision LXD Container
hosts: localhost
gather_facts: false
tasks:
- name: Ensure LXD container exists
lxd_container:
name: my-container
state: started
- name: Install packages in the LXD container
ansible.builtin.package:
name: "{{ item }}"
state: present
with_items:
- nginx
- git

6. Now, run the playbook to provision the LXD container:

   ansible-playbook provision_lxd_container.yml
7. Finally, we have to verify the LXD container:

   sudo lxc list
