  The build process includes multiple stages:
  
  * The `build` command applies options and includes custom providers to create an optimized image.
  * The files generated by the `build` stage are copied into a new image.
  * In this runner image, the specific run configuration is applied. That configuration contains a keystore, the environment-specific hostname configuration, and database configuration.
  * In the entrypoint, the `kc.sh` enables access to all the distribution sub-commands.
  
  This example uses a multi-staged build to demonstrate the build and run steps.  However, you can also build a single-staged docker image by removing the following two lines:
  
  [source, dockerfile]
  ----
  FROM quay.io/keycloak/keycloak:latest
  COPY --from=builder /opt/keycloak/ /opt/keycloak/
