|
// It ensures that a container can be started when the daemon was improperly
|
|
// shutdown when the daemon is brought back up.
|
|
//
|
|
// The regression is due to improper error handling preventing a container from
|
|
// being restored and as such have the resources cleaned up.

|
|
// To test this, we need to kill dockerd, then kill both the containerd-shim and
|
|
// the container process, then start dockerd back up and attempt to start the
|
|
// container again.
