Upgrade Kubernetes Operator for Apache Cassandra and related resources in Kubernetes
Follow the steps in this topic to upgrade the Kubernetes Operator for Apache Cassandra and related resources in Kubernetes.
Kubernetes Operator for Apache Cassandra upgrades
To upgrade an existing Cassandra or DSE cluster in Kubernetes from a prior Kubernetes Operator for Apache Cassandra release to v1.7.1, apply the latest Kubernetes Operator for Apache Cassandra YAML manifest.
During the upgrade, Kubernetes Operator for Apache Cassandra preserves previously defined values such as the namespace (example: cass-operator), the resource type (example: cassdc), and the datacenter name (example: dc1), plus other default or customized settings specified in the prior release’s YAML manifest.
To apply the latest Kubernetes Operator for Apache Cassandra YAML manifest – on a local machine where you have already established a connection with a Kubernetes project and cluster – use a kubectl command.
For example:
kubectl apply -n cass-operator -f https://raw.githubusercontent.com/k8ssandra/cass-operator/v1.7.1/docs/user/cass-operator-manifests.yaml
Kubernetes Operator for Apache Cassandra returns a summary about the updates.
Sample Output:
