How does Docker isolate container processes from the host OS?

Answer
Docker uses namespaces and cgroups. Frame the concept in practical terms so you can explain it during interview discussion.
Docker isolates processes using Linux namespaces and cgroups, which create separate spaces for processes and manage their resource usage. This isolation means that a Java application running in a Docker container won't interfere with the host system's processes or resources, providing secure and predictable execution. For example, running `docker run openjdk` ensures the Java process is isolated from the host.
