List of Common Debugging

  • Cannot use VM on windows 10 and Docker at the same time
  • Cannot VPN into network and use Docker (nginex crashes) when working remotely
    • This seems to be related to the network drives?
    • If docker is running and then I vpn into the network, the computer detects no network drives
    • After running 'docker-compose down' and restating docker, the network drives appear
  • Cannot execute 'docker exec' command in git bash
  • If you are using DockerToolbox rather than Docker for Windows on Windows, see rm-docker-toolbox-setup

Delete yarn.lock file and node_modules and run

docker-compose up

again.

This time it should build. If not, or if this results in changes to your yarn.lock file, simply run

git checkout frontend/yarn.lock

to checkout the old version and then it should work again.
