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 --pid=host argument.

For example, do not start a container as below:

docker run --interactive --tty --pid=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 process 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 }}: PidMode={{ .HostConfig.PidMode }}'

If PidMode = "host", it means the host PID namespace is shared with the container and this is a finding.
