Upgrade Pulsar Helm release

Before upgrading your Pulsar installation, you need to check the change log corresponding to the specific release you want to upgrade to and look for any release notes that might pertain to the new Pulsar helm chart version.

We also recommend that you need to provide all values using the helm upgrade --set key=value syntax or the -f values.yml instead of using --reuse-values, because some of the current values might be deprecated.


You can retrieve your previous --set arguments cleanly, with helm get values <release-name>. If you direct this into a file (helm get values <release-name> > pulsar.yml), you can safely pass this file through -f, namely helm upgrade <release-name> apache/pulsar -f pulsar.yaml. This safely replaces the behavior of --reuse-values.


To upgrade Apache Pulsar to a newer version, follow these steps:

  1. Check the change log for the specific version you would like to upgrade to.

  2. Go through deployment documentation step by step.

  3. Extract your previous --set arguments with the following command.

    helm get values <release-name> > pulsar.yaml

  4. Decide all the values you need to set.

  5. Perform the upgrade, with all --set arguments extracted in step 4.

    helm upgrade <release-name> apache/pulsar \
    --version <new version> \
    -f pulsar.yaml \
    --set ...
