Service and Logging#

We've created the subcommand k0s install to allow users to easily install k0s as a service, and define its logging.

This is an alpha state feature.

Caveats#

This command is strictly a helper command. It is not meant to provide a fully-automated solution, since you can run k0s in multiple, very different ways.
It configures your service set-up as either a worker or a server, and will have different tasks, depending on the role you pick.
Supported services: OpenRC & Systemd

This is the default mode of operation. When a server role is picked, the installer will do the following:

Create user accounts for the different components (see https://github.com/k0sproject/k0s/blob/main/pkg/apis/v1beta1/system.go#L6)
Create a service file (OpenRC/Systemd) and redirects logging to /var/log/k0s.log.
If the --debug flag is used, it will also pass this flag along to the service file.
enable-worker (single-node) setup is not supported. If you would like to run your service in that way, a possible solution would be to run cmd install as worker, and edit the startup command by hand.

A worker cannot run with any other user, other than root, so no special users will be created.
The service file will include the --token-file flag, with a value that needs to be manually changed.
If the --debug flag is used, it will also pass this flag along to the service file.
