To learn more about Docker build-time variables, see the [docker build documentation](/engine/reference/commandline/build/#set-build-time-variables-build-arg).
#### Two-phase build
If your build process requires a component that is not a dependency for your application, you can use a pre-build hook (refers to the `hooks/pre_build` file) to collect and compile required components. In the example below, the hook uses a Docker container to compile a Golang binary that is required before the build.
```bash
#!/bin/bash
echo "=> Building the binary"
docker run --privileged \
-v $(pwd):/src \
-v /var/run/docker.sock:/var/run/docker.sock \
centurylink/golang-builder
```
#### Push to multiple repos
By default the build process pushes the image only to the repository where the build settings are configured. If you need to push the same image to multiple repositories, you can set up a `post_push` hook to add additional tags and push to more repositories.
