Frequently asked questions

What should I do to remove unnecessary Linux capabilities?

Remove any unnecessary Linux capabilities. This limits the potential damage if a container is compromised.

How can I prevent a container from binding to privileged ports using --cap-add NET_BIND_SERVICE?

How can I forbid privilege escalation within a container?

Use docker run --security-opt=no-new-privileges myapp:latest: This prevents processes inside the container from gaining elevated privileges.
