Reducing load on kube-apiserver
In this release, KubeDB operator has been updated to cache access to Secrets. In case of sidecars, we have passed the secrets via environment variable. This will significantly reduce load on kube-apiserver.
Add enableServiceLinks to db podSpec
Kubernetes exports an environment variable for every single service in the same namespace into every pod by default. This ends up being huge on large shared dev clusters. It appears to slow pod startup by a lot for things like elasticsearch, kafka, zookeeper. Now, you can disable injecting these environment variables by setting enableServiceLinks: false in the PodTemplate spec.
Memory leak fixes in Provisioner
A memory leak in the KubeDB Provisioner component was reported which will result to operator restart every 4-5 days. We have found a fixed a Go routine leak issue in the health checker. If the issue persists, please let us know.
ProxySQL Improvements
In this release, we have changed the ProxySQL api such that spec.mode is not required any more. It will be auto-detected by the operator. Also, ProxySQL will run using non-root proxysql user (uid 999 for debian based images and 998 for centos based images) by default in this release.
Postgres
We have added the PostgreSQL versions 15.3, 14.8, 13.11, 12.15, and 11.20 in this release.
Elasticsearch
We have added the Elasticsearch versions 8.6.2 and 8.8.0 in this release.
Auto acquire License in case of expired licenses
Previously KubeDB operator will only auto acquire license via license-proxyserver if no license file is provided. Now, KubeDB operator will also try to auto acquire license if the license file has expired.
KubeDB Gateway
We have released KubeDB Gatway v0.0.1 based on Kubernetes Gateway API . This offers a Envoy based Gateway that can be to expose databases running on one cluster to another Kubernetes cluster. The helm chart can be found here . You can see a demo here . Please reach out, if you are interested in trying it.
