KubeDB Upgrade Manual

This tutorial will show you how to upgrade KubeDB from previous version to 0.11.0.

Before You Begin

At first, you need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using kind.

Now, install KubeDB 0.9.0 cli on your workstation and KubeDB operator in your cluster following the steps here.

Previous operator

In this tutorial we are using helm to install kubedb 0.9.0 release. But, user can install kubedb operator from script too.

$ helm repo add appscode https://charts.appscode.com/stable/
$ helm repo update

# Step 1: Install kubedb operator chart
$ helm install appscode/kubedb --name kubedb-operator --version 0.9.0 \
  --namespace kube-system

# Step 2: wait until crds are registered
$ kubectl get crds -l app=kubedb -w
NAME                               AGE

# Step 3(a): Install KubeDB catalog of database versions
$ helm install appscode/kubedb-catalog --name kubedb-catalog --version 0.9.0 \
  --namespace kube-system

# Step 3(b): Or, if previously installed, upgrade KubeDB catalog of database versions
$ helm upgrade kubedb-catalog appscode/kubedb-catalog --version 0.9.0 \
  --namespace kube-system

$ helm ls
NAME           	REVISION	UPDATED                 	STATUS  	CHART               	APP VERSION	NAMESPACE
kubedb-catalog 	1       	Fri Feb  8 11:21:34 2019	DEPLOYED	kubedb-catalog-0.9.0	0.9.0      	kube-system
kubedb-operator	1       	Fri Feb  8 11:18:46 2019	DEPLOYED	kubedb-0.9.0        	0.9.0      	kube-system

Upgrade kubedb-operator

For helm, upgrade command works fine.

$ helm upgrade --install kubedb-operator appscode/kubedb --version 0.11.0 --namespace kube-system
$ helm upgrade --install kubedb-catalog appscode/kubedb-catalog --version 0.11.0 --namespace kube-system

$ helm ls
NAME           	REVISION	UPDATED                 	STATUS  	CHART               	APP VERSION	NAMESPACE
kubedb-catalog 	2       	Fri Feb  8 12:12:45 2019	DEPLOYED	kubedb-catalog-0.11.0	0.11.0      	kube-system
kubedb-operator	2       	Fri Feb  8 12:11:57 2019	DEPLOYED	kubedb-0.11.0        	0.11.0      	kube-system

Upgrade CRD objects

Note that, if any server becomes stale for using deprecated PgBouncerVersion, upgrading to a non-deprecated PgBouncerVersion will solve the issue as kubedb-operator will update the Statefulsets too.
