package restart

import "github.com/containerd/containerd/runtime/restart"

Package restart enables containers to have labels added and monitored to keep the container's task running if it is killed.

Setting the StatusLabel on a container instructs the restart monitor to keep that container's task in a specific status. Setting the LogPathLabel on a container will setup the task's IO to be redirected to a log file when running a task within the restart manager.

The restart labels can be cleared off of a container using the WithNoRestarts Opt.

The restart monitor has one option in the containerd config under the [plugins.restart] section. `interval = "10s" sets the reconcile interval that the restart monitor checks for task state and reconciles the desired status for that task.
