DKER-EE-002090 - Docker Enterprise exec commands must not be used with the user option.

Information

Do not docker exec with --user option.

Using --user option in docker exec executes the command within the container as that user. Do not run docker exec with the --user option , especially when running containers with dropped capabilities or with enhanced restrictions. For example, suppose the container is running as tomcat user (or any other non-root user), it would be possible to run a command through docker exec as rootwith --user=root option.

By default, docker exec command runs without --user option.

Solution

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

Do not use --user option in docker exec command.

A reference for the docker exec command can be found at https://docs.docker.com/engine/reference/commandline/exec/.
