Taking LXD Container Snapshots

One benefit Linux containers provide is the ability to quick spin up a number of containers. But from what are these containers based? LXD snapshots allow us to take point-in-time images of our containers and any work performed on these containers. In this lab, we take a preconfigured nginx-based web container and clone it to create the basis of a small web cluster.

    Launch and Review the New Container

    Launch the new container:

    lxc copy web01/1.0 web02
    lxc start web02
    

    View the IPv4 address of the container and attempt to access a website:

    lxc stop web02
    lxc delete web02
    lxc copy web01/1.1 web02
    lxc start web02
    

    Ensure nginx is working by running curl on the container's IP:

    lxc list
    curl \<ipv4\>
