Troubleshooting/Gotchas

• Problem: If you update the Gemfile and run ./go test, ./go shell or a similar command, you will see Could not find NEW_GEM_DEPENDENCY_NAME_HERE.
• Solution: Run ./go build to update your development docker image to include the new dependency.
• Problem: ./go start starts the development container, but it stops with exit code 1 after a few seconds. You check the logs and see a message like: A server is already running. Check /usr/src/app/tmp/pids/server.pid.
• Solution: Run ./go shell, cd /usr/src/app/tmp/pids, rm server.pid. Then exit the shell container and run ./go start again.
• Problem: You see an error message like ERROR: Service 'dev' failed to build: The command '/bin/sh -c useradd -ms /bin/bash $username' returned a non-zero code: 2 when running a command like ./go test or ./go start.
• Solution: Run ./go init before running any other ./go commands.
