Note: Docker requires absolute paths for binding mounts, so in this example we use `pwd` for printing the absolute path of the working directory, i.e. the `app` directory, instead of typing it manually - `node:12-alpine` - the image to use. Note that this is the base image for our app from the Dockerfile - `sh -c "yarn install && yarn run dev"` - the command. We're starting a shell using `sh` (alpine doesn't have `bash`) and running `yarn install` to install _all_ dependencies and then running `yarn run dev`. If we look in the `package.json`,
