Launching my first Linux Container

Hello- New to Docker hub tools and need some guidance. It seems I have several steps before I can deploy and configure my Docker Hub. I want to launch an IBM Filenet CPE 5.5.0 Linux Container on my Windows 10 Pro system(s). I have plenty of CPU, RAM and Disk space.

Are these the correct steps:

  1. SIgn up for docker and docker Hub
  2. DL the Windows Docker Desktop
  3. DL RHEL 7.4 ISO
  4. DL the IBM CPE 5.5.0 Container Image

Feels like I am missing something here before this all works properly.
