Can't run Docker container about glot-run

[prasmussen]

You can pass the environment variables to docker run.
Here is a slightliy modified bash script i have used in the past to start the container:

docker run \
  -p 8090:8090 \
  --detach \
  --restart always \
  --env API_ENVIRONMENT="production" \
  --env API_HTTP_LISTEN_IP="0.0.0.0" \
  --env API_HTTP_LISTEN_PORT="8090" \
  --env DATA_PATH="/home/app/data/" \
  --env LOG_PATH="/home/app/log/" \
  --env BASE_URL="https://run.glot.io" \
  --env ADMIN_TOKEN="secret" \
  --env DOCKER_API_URL="http://10.0.0.127" \
  --env DOCKER_RUN_TIMEOUT="15" \
  --env MAX_OUTPUT_SIZE="100000" \
  --volume /containers/glot-run/data:/home/app/data \
  --volume /containers/glot-run/log:/home/app/log \
  glotrun

@prasmussen Thanks, but I'm still not able to get it working. When I make a POST to /languages/python/latest with data {"files": [{"name": "main.py", "content": "print(42)"}]}, and the Authorization: Token usertoken. I no longer get the auth failed error, but I get a HTTP 500 error after aboutt 8 seconds.

This is the stack trace in the docker logs.

it seems to be some sort of problem in spawning the docker container to run the program?

[prasmussen]

Yes, it seems like container_create process times out. Make sure that that the glotrun container is able to access the docker api. Try doing curl $DOCKER_API_URL/version from inside the container. This should return the docker version. (Probably need to install curl first)

[arxenix]

I got it working. I did have the languages registered. The problem was that I was using the incorrect docker API URL (I just copied the example one)

[prasmussen]

Seems like the API_HTTP_LISTEN_PORT variable is not set correctly.

[arxenix]

Yeah, I just realized that. I'm not sure how to set it correctly though. I know its not an issue with your project but could you help me out?

[arxenix]

Thank you so much for the help! It seems to be working now. Thanks for open sourcing this great project

[arxenix]

@prasmussen sorry, 1 last question! I tried sending a curl POST request to it, but I get an invalid token error even though I have the header Authorization: Token secret, and I set the env variable ADMIN_TOKEN to secret. Do I need to hash it or something?

[prasmussen]

Note the admin token only works for the the /admin endpoints, to create a normal user you can use the following query:

curl -sv -H "Authorization: Token secret" -H 'Content-type: application/json' -X POST -d '{"token": "af4c0a23-7b42-4207-b61c-1430c9637056"}' http://localhost:8090/admin/users

@bobacadodl did you register the language in glot-run? Did you download the python container in your docker daemon?

Check #9 for some scripts to download and register all languages 😉
