VRS mono headless inside Docker

[testthevrs]

Hello,

I followed the Linux install instructions, dockerized it, VRS runs and works -nogui. Webserver works, everything. However, If I pass -createAdmin:admin -password:password so I can configure, it crashes.

....

[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeInitializationException: The type initializer for 'System.Windows.Forms.XplatUI' threw an exception. ---> System.ArgumentNullException: Could not open display (X-Server required. Check your DISPLAY environment variable)

It's trying to open a window. Happens with both the current and preview. Since it's headless with no X11, obviously crashes and exits.

Is there documentation on the Configuration.xml?

Hello

Did you get this sorted please? As I would love to put it into a docker.

Cheers

No, and deeper testing showed the code is terribly inefficient. SQLite disk i/o is atrocious. Needs to be activated with :memory

No response from Dev or Community.

Hi all,

I have a working Docker image running on arm32v7 (Raspberry Pi 3 Model B). It is not perfect but it is currently working and I aim to improve it for my own uses.

Please see:

ps. There is a dev branch with a container 1/3 the size (105Mb vs 306Mb) I am working on.
