Hi! New here wanted to get up and running quickly so …
FatDog64-810 (Puppy Linux)
Single mountpoint ‘gotcha’ overcome by edit of /etc/docker/daemon.json:
{
“graph”:"/mnt/sda1/docker"
}
… am actually up and running but with the warnings listed below.
I am so new to this that genuinely, I have not a clue what I’m doing … help!
What I want:
… how do I go about that?
Other info below:

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
