This Apache Pulsar Helm Chart release contains several important new features, bug fixes, and some potential breaking changes. Most importantly, it ships with Apache Pulsar 2.10.2, by default.
- Switch from custom deployment of Prometheus and Grafana to using the kube-prometheus-stack. This change includes enabling
PodMonitorsby default for the Broker, Bookkeeper, Zookeeper, Autorecovery, and Proxy pods, as well as deploying the related CRDs by default. If this will be a problem, here is documentation to disable the CRD deployment. Additionally, the Grafana Dashboards that were previously deployed will no longer ship with this Helm Chart. Here is documentation on available alternatives. Here is the related PR #299.
- When upgrading from any previous version of the helm chart, there are a few things to consider. First, this is the first release of the Helm Chart that packages a 2.10 docker image as the default version of Apache Pulsar. Notably, that docker image is run as a non root user, by default. As a result, you may have issues with Zookeeper and Bookkeeper file system permissions. If so, you may need to use the following in your initial values file. See https://github.com/apache/pulsar-helm-chart#upgrading-to-apache-pulsar-2100-and-above-or-helm-chart-version-300-and-above for more instructions.

- When upgrading to the kube-prometheus-stack, the helm chart will not install the CRDs by default. You can install those following these instructions: https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack#from-40x-to-41x.
