How to add a profile to a container in LXC

Did you know that a profile is a set of configuration options that can be applied to one or more containers in LXC?

In fact, profiles are used to define settings like network configuration, storage devices, kernel parameters, and so on. Furthermore, profiles help us apply the same configuration settings to multiple containers, thereby saving us time and simplifying management.

Let’s take a look at how we can add a profile to an existing container, with the “lxc profile apply” command.

1. First, we have to list the available profiles with the following command:

   lxc profile list

   The above command displays a list of all the profiles that are currently defined on our system.
2. Next, we have to run the following command to create a new profile called “newprofile”:

   lxc profile create newprofile

   Remember to replace “newprofile” with any name we prefer.
3. Then, we have to define the settings for the new profile by running this command:

   lxc profile edit newprofile

   Remember to specify settings like network configuration, storage devices, kernel parameters, and so on.
4. Finally, it is time to apply the profile to the container with the following command:

   lxc profile apply newprofile containername

   Remember to replace newprofile and containername with the name of the new profile and the container we want to apply this profile to respectively.

After the above steps, the new configuration settings will come into play the next time you start the container.

Furthermore, we can also add a profile to a container when we create the container using the “lxc launch” command.

For instance:

lxc launch imagename containername --profile profilename

This will create a new container called “containername” based on the “imagename” image, and apply the “profilename” profile to the container.
