# Embark for Docker ## Updating versions * Open `Dockerfile` * On the `ENV` directive, update necessary versions. An exception to this is the NodeJS version, which needs to be updated in the `FROM` directive instead. ## Building Building requires Docker to be installed on your local machine. To build, run: ``` $ script/build ``` ## Releasing Releasing requires that you're authenticated to Docker Hub. To do so, run: ``` $ docker login ``` After, or if you're already authenticated, run: ``` $ script/build --release ```
