Minimserver 2 docker on synology : license file has zero length

[simoncn]

This error message hasn't killed any license activations.

On Synology, you can activate a native MinimServer instance and any number of Docker instances, all sharing the same license activation. To make this license sharing work, the native instance creates a file named minimserver-starter.license and the Docker instances read this file as part of the license sharing scheme.

For some reason (perhaps your problems with Java 8), the native MinimServer instance didn't create the minimserver-starter.license file correctly (it has zero length instead of the correct length of 129 bytes). You will need to fix this problem before you can run any Docker instances.

To fix this problem, you need to install and start the native MinimServer package for Synology. This should automatically create a file named minimserver-starter.license in the MinimServer/appData folder and this file should have a length of 129 bytes. You can check for this using File Station. When this file has been created correctly, you can stop the native MinimServer instance using Package Center. If you now start a Docker instance, it should run without errors. You don't need to do anything with puid or pgid.

There is no need to have the native MinimServer instance running after the minimserver-starter.license file has been created correctly.
