Trying to install Mattermost on Plesk

Thank you for the reply, though it’s very interesting that it’s a ChatGPT situation, so I’m glad to get an answer, be it in an unconventional way.

I did look at Mattermost Docker Installation Guide link which you provided. I have a question:

  1. In order to use Docker, which I have never done before, is this something that I must install first on my server or am I to install it on MacOS on my laptop and run it from there to communicate install into my server? The Install Docker choices are MacOS, Windows, Ubuntu, and Fedora so it looks like I’m to install it on a computer, not my server? My Plesk server is running CentOS Linux 7.9.2009. It’s unclear to me where I would be running Docker from to accomplish this.
