Additional Information

[mbianchidev]

CloudNativePG is one of the projects that I follow closely in the landscape for many different reasons.

• First and foremost it's the demonstration that running Stateful workloads on Kubernetes is more than possible and it's quite easy.
• It's an amazing community that welcomes all the cool and different DB vendors and individual contributors alike
• It attracted quite a lot of buzz when they decided to open their applications for the mentorship program, even with my mentees
• Maintainers are super helpful in answering questions both on Slack and at events in person, where they are more than present and across the globe
• Some of the same maintainers also contribute and collaborate with SIG Storage in Kubernetes

For these reasons I cannot be happier to vouch for what would be their well deserved Incubation level in the CNCF Landscape.

I'm excited to support CloudNativePG's application for incubation status. I was fortunate to work with CNPG during my time at Tembo, where we built our platform on top of it, and it proved to be an excellent foundation. The project's quality, stability, and the team's responsiveness were consistently impressive.

Since CNPG joined the Sandbox in January 2025, it's been great to see the project's continued growth and maturation. The comprehensive governance improvements, expanded adopter base, and strong technical foundation they've built make them a solid candidate for incubation. Congratulations to @gbartolini and the entire team on reaching this milestone!

We use CNPG for all of our on prem kubernetes clusters and I am very happy with it and the support provided.

[jpetazzo]

10 years ago, running databases on Kubernetes was not recommended, and you would definitely get weird looks from your fellow SREs if you did it.

5 years ago, running databases on Kubernetes was challenging, but the Kubernetes storage ecosystem was blooming (with the stabilization of the CSI, database operators...) so it was definitely possible, and a viable option, especially for folks running large numbers of database clusters.

Today, running a database on Kubernetes is a totally normal thing to do, and operators like CNPG make it easy for developers (not even DBAs!) to deploy production-grade PostgreSQL databases on regular Kubernetes clusters. With a YAML manifest that fits on a 80x25 screen, we get a PG cluster with multiple replicas, automated failover, automated switchover during node maintenance, backups (giving us easy access to features like Point-In-Time-Recovery), and even the ability to provision database clones in mere seconds thanks to the integration with CSI volume snapshots. Along with Prometheus exporters and Grafana dashboards showing us replication status and tons of other metrics that we didn't have on our previous managed PG provider.

I cannot use enough words to express how grateful I am for the work of the CNPG authors and maintainers for giving us that amazing open source software, and I wholeheartedly support their application for incubation status with the CNCF! 🫶🏻

Thanks to CNPG, I've migrated all my databases to Postgres. I use it in all my local and cloud K8s clusters.

The stability, reliability, and production readiness are unmatched. Thanks to CNPG, databases in K8s are finally what they should be - cloud-native!

A must-have in the CNCF portfolio! I without a doubt support their application for incubation status at CNCF! ❤️
