Fix Recommendation

This fix only applies to the use of Docker Engine - Enterprise on a Linux host operating system.

Do not start a container with --ipc=host argument.

For example, do not start a container as below:

docker run --interactive --tty --ipc=host centos /bin/bash

Check Contents

This check only applies to the use of Docker Engine - Enterprise on a Linux host operating system.

Ensure the host's IPC namespace is not shared.

via CLI:

Linux: As a Docker EE Admin, execute the following command using a UCP client bundle:

docker ps --all | grep -iv "ucp\|kube\|dtr" | awk '{print $1}' | xargs docker inspect --format '{{ .Id }}: IpcMode={{ .HostConfig.IpcMode }}'

If IpcMode="shareable", then the host's IPC namespace is shared and this is a finding.
