Game JS Compilation in Docker Image failed. #27

Closed jrstarke closed 6 years ago

jrstarke commented 6 years ago

When running the docker image, if you attempt to start a game, the browser appears blank. Looking at the browser console, there is the following exception:

I'm not able to replicate this, can you specify what docker image you're running?

As an aside, webpack compilation should not be happening inside the docker image if you are pulling from docker hub, are you building the image locally?

Dkendal commented 6 years ago

To clarify a bit: the docker image is not intended for developing the elixir project itself, as it produces a full production release, it is intended to be run locally to develop competition snakes against. Perhaps that wasn’t clear in the documentation.

If you wish to develop against a development build of the server then I would recommend checking out https://github.com/battle-snake/battle_snake#compiling-from-source

Docker output should look like:

 > docker run -it -P --add-host="localhost:192.168.0.137" battlesnake/battle_snake:latest

Strange that you're not able to replicate this. I can replicate it perfectly.

I get the JavaScript Console error mentioned above by running docker run -it -p 3000:3000 battlesnake/battle_snake, creating a new came, and passing it one of my previous snakes (which is still live), then clicking Show.

Further, if I run docker run -it -p 3000:3000 battlesnake/battle_snake cat /root/prod/lib/bs/priv/static/js/game-76287735d82777240a5dd816d6e6bd40.js | grep "Compilation" you can see that the Error message mentioned above is actually compiled into the JS in the Docker image.

Hope that helps.
