I'm attempting to get RabbitMQ up and running inside a Windows container but without a whole lot of luck. I've copied into the container the installation directories for RabbitMQ and Erlang but when I attempt to run erl.exe I'm told that beam.smp.dll is not able to be loaded.
PS C:\Program Files\erl8.2\bin> .\erl.exe
Unable to load emulator DLL
(C:\Program Files\erl8.2\erts-8.2\bin\beam.smp.dll)
Running the same command on the same installation directory on the host machine works just fine. I've checked that the file exists and that the checksums match. My bet is that there is some subtile difference in how the container loads the file and how the host loads the file. I'm just not sure where to even start looking.
Here is my Dockerfile which works. I can connect to RabbitMQ and the logs show it is running correctly, and I can login to the management UI using the guest/guest login from my host using IP/hostname of container.
