This works well for me, and I hope it will for you too...

Focus on the new community version of LMS version 8 and above
First you need to find a container image for LMS. There are several ways to do this, and here is one:
Start Container Station from App Center and click +Create Container.
In the search bar, type Logitech and hit return
You should see 4 repositories along the top of the list:
Recommended, Local, IoT and Docker Hub
The search function will stop at the first hit going from left to right.
So if you already have a container package downloaded locally whose name contains the word "logitech", it will find it and stop the search.
To search in the other repositories, you have to click on the "Docker Hub". That should give you a long list of packages to choose from - all with names that contain the word "Logitech". Which package to choose, is up to you, but I recommend using the lmscommunity/logitechmediaserver:8.3.0 or higher.
Once you have chosen which package you want to install, click on install. In the create container window, you can change the name of the package you are about to install along with a few other parameters. Select Advnced Settings and add the following Environment Variables:
LC_ALL C.UTF-8
TZ Asia/Singapore (or whatever is correct for your location)
You will find the syntax for every other place on earth here: https://en.wikipedia.org/wiki/List_of_t ... time_zones.
In order for Logitech Media Server (LMS) to be able to retrieve data from, and pass data to, the outside of the container, you must mount Shared folders for it to use. Most likely your music collection is stored outside the container (it's not a good idea to store media files inside containers as they will vanish when (if) you remove or delete the container.)
Also, you need to consider how you want port mapping to be handled. By default, Container station will configure the container network in bridge mode (NAT) with an internal network in the 10.x.x.x range while your NAS probably is connected to a 192.168.x.x network. The default LMS ports (9000, 9090 and 3483) are mapped into random port numbers which change every time you start and stop the container (which means also every time you reboot your NAS). This is not very practical - for obvious reasons. [Edit: this can be controlled from the Network Advanced Setting section of CS)]
An easier alternative is to configure the containers in host mode. That way, the container becomes part of the NAS network and no port mapping takes place. Of course there are disadvantages with this also. The container suddenly becomes less isolated and vulnerable to external problems. This is a security issue you have to consider.
Click on the "Advanced Setting" and then in the menu on the left side click on Network. Then change the NAT field to host.
Then move down to the Shared Folder section. In this section, make the following settings:
Everything in column #2 in this table is from my own setup. You need to select the host path shares that you wish to make available to the container. You will only be able to select shares already established in the NAS (QTS), so unless you have already done so - you must terminate and share you music folder first (using File Station) along with any other folders you wish to use (Playlists, state etc.)
If your Music library has a lot of subfolders (several thousands), then it may take a while before the setup page becomes responsive - and you can finally click on "create".
Now the package is downloaded from the repository and the container is created. This can take a while depending on your internet connection speed. These packages are often several hundred megabytes in size. Just be patient. You can follow the progress in the console window and by clicking on the background task icon (the inbox icon in the upper right corner of the window).
Once installation is completed, Logitech Media Server is started and it takes some time before it gets setup properly and the URL becomes visible in the container window. You cannot access LMS until the URL comes alive. Ones the URL shows up, it should be clickable as an active link that will take you to a new tab in your browser and open the default LMS Web GUI.
From here on, the rest is up to you.
I am successfully running not only LMS in a container, but also Plex and Madsonic, all using the same Music library. For obvious reasons, it doesn't make much sense to run Kodi (XBMC) in a container as Kodi is not a server, and the main purpose of Kodi is to shine on you living room TV. I haven't found a way to make the HDMI i/f available to a container. I guess that's why QNAP released Linux Station and HD Station (?)
