Subject: [PATCH] [sosnode] Don't create a container if we're in a container
|
|
|
8f0bb7 |
|
|
|
8f0bb7 |
If sos-collector is being launched from a container on a containerized
|
|
|
8f0bb7 |
host, we could potentially attempt to create a nested container.
|
|
|
8f0bb7 |
|
|
|
8f0bb7 |
This change means we treat a sos-collector run that is already in a
|
|
|
8f0bb7 |
container as a "normal" host and don't attempt the containerized bits.
