The code starts an app on a node instance running Alpine 3.13 with a production environment set. First, it installs git, openssh, and npm. Next, it copies the app's package.json, yarn.lock, and ./ files to the root of the instance and sets the environment variables NODE_ENV and WORKDIR toProduction. Finally, it builds the app using yarn.
