After freezing a container the processes inside it will not be serviced by the host CPU scheduler, although they will still take up memory. Freezing can come in handy when you want to stop a container momentarily (for a few seconds) but you don’t want to stop it altogether. Lxc-utopic RUNNING 10.0.3.157 - YES Freezing containers Freezing containers will stop (or 'freeze') the processes running inside a container. When we run lxc-ls -fancy after setting the autostart parameters, we see that the container is now set up to start automatically when the host boots: With these parameters, the container will start when the host server boots, then the host system will wait 5 seconds before starting any other containers. For example, we can set our lxc-utopic container to auto-start by adding the following lines to the /var/lib/lxc/lxc-utopic/config file: This is typically found in /var/lib/lxc//config. If you want a container to start at system boot, you can configure that behavior in each container's configuration file. In part 2, we discuss some additional features and nifty things you can do with LXC containers that will simplify their use and make them more flexible to suit your needs.Īuto-start a container By default a new container will not start if the host system is rebooted.

Introduction In part 1 of this series, we gave a brief overview on what LXC containers are, how to deploy, access and destroy them in Ubuntu 14.04 LTS. This article was written by Kent Baxley (Canonical Field Engineer) and Jose De la Rosa (Dell Linux Engineering).
