🚀 Release 1.18.0-rc2 (2025-11-17)

🗒 NOTES

StackGres 1.18.0-rc2 is out! 🎊 🍾

Among other features this release will allow you to upgrade your clusters using a strategy and with a renewed rollout implementation that no longer relies on Jobs but is handled directly by the operator. You can still rely on SGDbOps to perform restarts, security upgrades and minor version upgrades operations or configure the clusters to preform them in an automatic fashion.

Another important change is the ability to set the version of your SGCluster or SGShardedCluster directly in the cluster resource. The final Postgres version (and the final extensions versions too) will no longer be changed by the operator, instead it will be set in the status and will be updated by the operator. This change will allow a much better integration with DevOps tools!

So, what you are waiting for! Upgrade now and have a look at the future of StackGres!

🆙 UPGRADE

To upgrade from a previous installation of the StackGres operator's helm chart you will have to upgrade the helm chart release.
For more detailed information please refer to our documentation.

To upgrade StackGres operator's (upgrade only works starting from 1.1 version or above) helm chart issue the following commands (replace namespace and release name if you used something different):

helm upgrade -n "stackgres" "stackgres-operator" https://stackgres.io/downloads/stackgres-k8s/stackgres/1.18.0-rc2/helm/stackgres-operator.tgz

IMPORTANT: This release is incompatible with previous alpha or beta versions. Upgrading from those versions will require uninstalling completely StackGres including all clusters and StackGres CRDs (those in stackgres.io group) first.

Thank you for all the issues created, ideas, and code contributions by the StackGres Community!
