Auto Deploy CI template v1 will is deprecated going forward.
 
     Since the v1 and v2 versions are not backward-compatible, your project might encounter an unexpected failure if you already have a deployed application. Follow the [upgrade guide](https://docs.gitlab.com/ee/topics/autodevops/upgrading_auto_deploy_dependencies.html#upgrade-guide) to upgrade your environments. You can also start using the latest template today by following the [early adoption guide](https://docs.gitlab.com/ee/topics/autodevops/upgrading_auto_deploy_dependencies.html#early-adopters).
