We are excited to announce the release of version 2.0 🎉 , a major update that brings significant new features to the postgresql_cluster project:

• This release introduces the capability to deploy PostgreSQL clusters across various cloud providers, including AWS, GCP, Azure, DigitalOcean, and Hetzner Cloud.
• Additionally, we’ve developed a User Interface (UI) - PostgreSQL Cluster Console, designed to streamline the deployment process, making it easier than ever to set up your clusters.

With this release, postgresql_cluster will automatically configure the following:

1. A virtual machine (with a dedicated data disk), with all cluster components installed and configured.
2. A cloud load balancer to serve as the entry point for database connections.
3. A storage bucket, and configured backups using pgBackRest.

🙏 A special thanks to @gslabs-dev for his contribution, @Rainbrand for developing the UI, and @ngurban for the API development.

✨Inspiration: We drew inspiration from the designs of Google Cloud Console, Aiven for PostgreSQL, and Postgres.AI, which greatly influenced our approach.

🔭 Looking ahead, we are planning to enhance the PostgreSQL Cluster Console with features that will enable you to manage your PostgreSQL clusters directly through the UI. If you’re interested in supporting the continued development of this feature, please consider becoming a sponsor.
