Upgrade KubeBlocks
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.
Set keepAddons.
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:
Check the current KubeBlocks version.
helm -n kb-system list | grep kubeblocks
Set the value of keepAddons as true.
helm repo add kubeblocks https://apecloud.github.io/helm-charts
helm repo update kubeblocks
helm -n kb-system upgrade kubeblocks kubeblocks/kubeblocks --version \{VERSION\} --set keepAddons=true
Replace {VERSION} with your current KubeBlocks version, such as 0.7.2.
Check addons.
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}'
Install CRD.
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
Upgrade KubeBlocks.
helm -n kb-system upgrade kubeblocks kubeblocks/kubeblocks --version 0.8.1 --set dataProtection.image.datasafed.tag=0.1.0
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
Download kbcli v0.8.
curl -fsSL https://kubeblocks.io/installer/install_cli.sh | bash -s 0.8.1
Upgrade KubeBlocks.
kbcli kb upgrade --version 0.8.1 --set dataProtection.image.datasafed.tag=0.1.0
kbcli will automatically add the annotation "helm.sh/resource-policy": "keep"
to ensure that existing addons are not deleted during the upgrade.
If you are currently running KubeBlocks v0.6, please upgrade to v0.7.2 first.
Download kbcli v0.7.2.
curl -fsSL https://kubeblocks.io/installer/install_cli.sh | bash -s 0.7.2
Upgrade to KubeBlocks v0.7.2.
kbcli kb upgrade --version 0.7.2
