Thank you for reporting.

@davimacedo Do you have any suggestion for this Docker related issue?

[davimacedo]

Can you try to run the container with the following command?

docker run --name my-parse-server -v cloud-code-vol:/parse-server/cloud -v config-vol:/parse-server/config -p 1337:1337 --link my-mongo:mongo -d parse-server --appId APPLICATION_ID --masterKey MASTER_KEY --databaseURI mongodb://mongo/test --cloud /parse-server/cloud/main.js

@davimacedo Yes it work. Thank you very much. I think you should update the Documentation for Docker regarding this problem or add default value for cloud parameter.
