Upgrade from KubeBlocks v0.7Upgrade from KubeBlocks v0.6

In this tutorial, you will learn how to upgrade to KubeBlocks v0.8.

Execute helm - n kb- system list | grep kubeblocks or kbcli version to check the current KubeBlocks version you are running, and then upgrade it.

KubeBlocks v0.8 streamlines the default installed engines and separates the addons from KubeBlocks operators to KubeBlocks- Addons repo, such as greptime, influxdb, neon, oracle- mysql, orioledb, tdengine, mariadb, nebula, risingwave, starrocks, tidb, and zookeeper. To avoid deleting addon resources that are already in use during the upgrade, execute the following commands:

helm - n kb- system list | grep kubeblocks

helm repo add kubeblocks https://apecloud.github.io/helm- chartshelm repo update kubeblockshelm - n kb- system upgrade kubeblocks kubeblocks/kubeblocks - - version {VERSION} - - set keepAddons=true

Replace {VERSION} with your current KubeBlocks version, such as 0.7.2.

Execute the following command to ensure that the addon annotations contain "helm.sh/resource- policy": "keep".

kubectl get addon - o json | jq '.items[] | {name: .metadata.name, annotations: .metadata.annotations}

To reduce the size of Helm chart, KubeBlocks v0.8 removes CRD from the Helm chart. Before upgrading, you need to install CRD.

kubectl replace - f https://github.com/apecloud/kubeblocks/releases/download/v0.8.1/kubeblocks crds.yaml

helm - n kb- system upgrade kubeblocks kubeblocks - - version 0.8.1 - - set dataProtection.image.

To avoid affecting existing database clusters, when upgrading to KubeBlocks v0.8, the versions of already- installed addons will not be upgraded by default. If you want to upgrade the addons to the versions built into KubeBlocks v0.8, execute the following command. Note that this may restart existing clusters and affect availability. Please proceed with caution.

helm - n kb- system upgrade kubeblocks kubeblocks /kubeblocks - - version 0.8.1 - - set upgradeAddons=true

If you are currently running KubeBlocks v0.6, please upgrade to v0.7.2 first.

curl - fsSL https://kubeblocks.io/installer/install_cli.sh | bash - s 0.7.2
