Docker CLI is used to access #202110201636 REST API. It could be done within a local host or from a remote client. Run docker run -H={ip-addr}:{port} if you are accessing a Docker host remotely.

For example, although as appeared the PID for the containers viewed from Docker CLI are always started from 1, if we viewed it from the main operating system’s perspective, the PID might be totally different. The operating system treats that as a regular task just like other processes, but since those tasks are in Docker’s namespace, it cannot see others’ resources and will not be seen from them as well.
