Migration to GitHub Container Registry
In this release we have migrated all docker images published by AppsCode to the GitHub Container Registry (ghcr.io) from the Docker Hub. Going forward, we are going to publish docker images exclusively to ghcr.io . This will resolve any issues related to rate limiting by Docker Hub. You can find the images HERE .
One chart to Install KubeDB and Stash
We have created a new kubedb-one chart that includes both KubeDB and Stash. You can find the details HERE
on what is included in the chart. To use it, simply can run the following command:
helm upgrade -i kubedb appscode/kubedb-one \
--version v2023.04.10 \
--namespace kubedb --create-namespace \
--set-file global.license=/path/to/the/license.txt
Kafka
Monitoring using Prometheus & Grafana
KubeDB now offers support for monitoring Kafka clusters using Prometheus and Grafana dashboards. With the in-built JMX exporter, Kafka metrics can be easily exported to Prometheus via a service monitor, and Grafana dashboards can be created to visualize those metrics. KubeDB also provides a pre-built Grafana dashboard for Kafka metrics. For example, here’s a sample YAML for deploying a TLS-secured Kafka cluster with built-in monitoring support.
apiVersion: kubedb.com/v1alpha2
kind: Kafka
metadata:
name: kafka
namespace: demo
spec:
enableSSL: true
tls:

Here’s the KubeDB built Grafana Dashboard

Also, We have added support for Kafka version 3.3.2 & 3.4.0. From this release, Kafka docker images will be using OpenJDK-based Java version 11 instead of Java 8 as it has been deprecated since 3.0.0.

Bug Fix: When the database is created with the same name in multiple namespaces, multiple redis instances was trying to own a single clusterrole, this bug is fixed in this release. Now to grant redis instances access to sentinel instances, only one clusterrole is created without owner reference.
MySQL
Bug Fix: Earlier MySQL instance was used to create a cluster role for reading the mysqlversion from the mysql-coordinator. When the database is created with the same name in multiple namespaces, multiple MySQL instances try to own a single cluster role, this bug is fixed in this release. Now to grant MySQL coordinator access to mysqlversions, only one cluster role mysql-version-reader is created without owner reference.
