It wouldn't be quite as one click as Sven Co-op. First I would start with the https://developer.valvesoftware.com/wiki/Half-Life_Dedicated_Server which is SteamCMD 90 (I did not see this in the Dockers listed in Community Applications). Or maybe I am blind? Then you would need to find a source for ts-3-final-linux.tar.gz (the linux server files and the windows server files are the same IIRC) here is one I found https://www.moddb.com/downloads/the-specialists-v30-server-linux as it states on that page the size and md5 hash and they have been around a long long long time in the Half-Life mod community. Inside that tarball is a folder called "ts" it is as simple as putting that ts folder in the same directory as the executable and then adding "-game ts" to the launch parameters.

I looked up the games in SteamCMD and it is not listed there. Since I am familiar with, but a bit rusty after all these years, I can just install "Half Life Dedicated Server" or "Sven Co-op" and modify things from there since it is not obtainable from SteamCMD directly. I can make a tutorial or something so you can add it to the Docker List possibly?

I was just getting ready to install a VM for some HLDSes and thought "Hmm, I wonder if there is a Docker container for this" and was pleasantly surprised to see a Sven Co-op server, used to run a bunch many years ago and want to get back into it again. Since you have plenty of other HLDSes, any chance of adding a "The Specialists" mod? https://www.moddb.com/mods/the-specialists ts-3-final-linux.tar.gz is the file you would want.
