Creating a docker container outside of Kasm

[ZuluPilgrim]

I have installed a stand alone Kasm server following https://www.kasmweb.com/docs/latest/install/single_server_install.html#installation-guide.

I am wanting to create a docker container for some other project that I am looking at but when I try and bring it up using docker compose up -d

I get

myadmin@kasm-01:~/docker/stirling-pdf$ sudo docker compose up -d && docker compose logs -f
[+] Running 1/1
 ⠿ Container stirling-pdf-stirling-pdf-1  Started                                                                                                                                                                                       8.3s

I have tried adding myadmin to the docker group but this did not help sudo usermod -aG docker myadmin

Is there another group that I need to add myadmin to?

Actually I just checked and the container is working just fine. So my questions are:

1. What does the above mean?
2. Do I need to worry about it?
3. How would I address it if I wanted to?

Once I logged off and on again, it seemed to be fine.
