Server setup on Windows Server 2016: we need help

Good Morning,

I have tried to follow this tutorial, but I feel I am missing a lot of information from this procedure. I am very new to using docker.

I also get an error of: ERROR: client version 1.21 is too old. Minimum supported API version is 1.24, please upgrade your client to a newer version

–I get this running docker-compose up

I am trying to follow this tutorial for a nested virtual environment held at Azure.

VM: Window Server 2016
Docker Desktop is install:
Docker version 19.03.5, build 2ee0c57608

I am just confused, I get errors when switching from Windows Container to Linux from the task bar…

Where do I download Mongodb? I put the docker-compose.yml file under resources, how do I start the RocketChat server.

Please help!
