Docker Containers from Dockerhub with TrueNAS Scale

Happy Monday, everyone.
Today i thought about coming back to some server stuff and showing how to add docker containers that aren't part of the TrueCharts list to our TrueNAS Scale server. It's super easy, but when I first tried the ports gave me issues so figured could help someone skip over this trouble shooting step in the future.
Something I forgot to mention was that I did update to 22.12.4.2 but docker stopped working so reverted back to 22.12.2 for this video. Not sure why the update didn't work but reverting was easy to do and docker started working right away again.
Let me know what you think. This should work for any docker container that uses a port to access a GUI (not pipeline containers that we might try in the future for bioinformatics pipelines, those are a bit different). Containers like Shiny servers, WebODM, etc. Pretty cool!

Thanks for the great walk-through.

[@Finnick5]

Thanks ! You solved my problem 🙏

RIP Truecharts

[@alexsoupir]

Sadly agree. iX killed the ability to run docker in some update and will introduce again in the next version, and in the mean time can't use True charts either. No easy way until this fall - wanted a custom image but can't without some jailmaker which I think I read the developer is no longer going to work on? Need to read more but really unfortunate.

[@MustKilLL]

@alexsoupir yeah dev is done. I'm sure what's next. im running docker rn, but its not the same true charts was great!

thanks!

Awesome!! that helps a lot, by any chance could you please do a tutorial in how to deploy a docker container running windows in True NAS due to my CPU does not support KVM extensions, I think there are many guys looking in how to do it, Thanks!!!!!!

[@alexsoupir]

Going to have to look and see if there is an easy way. Current version of TrueNAS doesn't work with custom docker images or docker compose - they are going to add it in a version closer to the end of this year. At that time I could try. Found this: github.com/dockur/windows which, if familiar with setting environmental variables in TrueNAS I think could be worked through.

Hey, this isn´t working on my TrueNAS Scale?! When I go to the "Apps" tab, there is no "Installed Applications", "Available Applications", "Manage Catalogs" and "Manage Docker Images" to chose. It looks different. When I go to Apps, there is just "Installed" at the top and "Applications" below. On the right upper corner is a blue "Discover Apps" button, which opens the lib, but here is also nothing with docker.. Was there a GUI upgrade? Was this option removed? Do I have to set something differently in TrueNAS? Isn´t pulling a Docker Image and starting it from the Apps no longer possible? Thank you in advance! :)

I don't have the most updated version of TrueNAS because, for me, they broke Docker in v23 the way I was using it in v22. The version I had that worked I think was 22.12.2, and have seen others on Reddit say in recent versions things have been breaking everywhere (most recently there's a RAM leak/release failure??). I haven't updated to v23 or even v24 because of the constant issues I see others have online in combination with the docker containers no longer working. Even tried to use docker in the terminal on TrueNAS v23 and it still threw out errors. Very frustrating. In other posts too, it looks like they're trying to move away from docker in favor of docker-compose, but i'm not familiar with docker compose (another reason i'm sticking with the old version of the OS). Unpopular opinion, but seems like a constantly changing, using users as the test case, operating system that is only friendly to people who like to solve problems constantly. They also seem to be at ends with TrueCharts for whatever reason. If you want, you can try to install the old v22 here: www.truenas.com/docs/softwarereleases/ see if that allows you to install containers and start apps. If so, then it's definitely something iX has been doing with TrueNAS. I have nothing super security focused so staying a few versions behind until they figure out their issues is no problem to me. Don't like the idea of having to constantly fix things once they are working. (sorry for the minor rant)

@@alexsoupir thank you very much for the detailed explanation! I started all this 1 week ago, so Im totaly new to all of this networking stuff and yes its a veeeerrry wide and often frustrating field to me so far... I even thought about switching to unraid, since a friend of mine is constantly talking about how perfekt it is...but 250 bucks for the unlimited update version is a lot! Even more than my hardware :D

[@alexsoupir]

@@Pyrocraker haha I'm with you on the unraid thing. If it was free I'd probably switch too. Been thinking about playing with Ubuntu server since docker is really the thing I currently rely on the most but it's hard to choose one way or another. Once you find one that works for you, then can stick with it. Hard to initially find it though. Like I mentioned maybe an older version of truenas is the way to go. Find your fit and the ride it along.

Hey @alexsoupir, I made a video on using docker compose on TrueNAS with Sandboxes and Jailmaker. Jailmaker

[@InformaticFreakTutorials]

They moved the interface from "Launch Docker Image" to "Discover Apps" > "Custom App".
