Hello all. I’m sure this is something extremely simple (likely involved directories or some Docker nuance) that I’m just not seeing. I’m trying to get the Go runtime to work alongside my Lua runtime and the server is starting but I’m finding some abnormal behavior that I don’t know how to resolve.
Below are the Dockerfile and docker-compose.yml files I’m using along with the output from my docker build command. The server is starting up with no errors however the Go module doesn’t run or initialize. Upon inspecting the container on first startup, there is no backend.so file in the modules folder where everything else is populated. If I shutdown the container the file shows in the container but none of the other files do. Is the mounting of the volume overwriting the file in the container? Is the file not being copied over until after the container runs? I’m at a bit of a loss
