Upgrade KubeBlocks
With the release of KubeBlocks v0.8.0, Addons are decoupled from KubeBlocks and some Addons are not installed by default. If you want to use these Addons, install Addons first by index. Or if you uninstalled some Addons, you can follow the steps in this tutorial to install them again.
This tutorial takes elasticsearch as an example. You can replace elasticsearch with the Addon you need.
The official index repo is KubeBlocks index. Addons are maintained in the KubeBlocks Addon repo.
Make sure the major version of Addons and KubeBlocks are the same.
For example, you can install an Addon v0.9.0 with KubeBlocks v0.9.2, but using mismatched major versions, such as an Addon v0.8.0 with KubeBlocks v0.9.2, may lead to errors.
(Optional) Add the KubeBlocks repo. If you install KubeBlocks with Helm, just run helm repo update
.
helm repo add kubeblocks https://apecloud.github.io/helm-charts
helm repo update
View the Addon versions.
helm search repo kubeblocks/elasticsearch --devel --versions
Install the Addon (take elasticsearch as example). Specify a version with --version
.
helm install kb-addon-es kubeblocks/elasticsearch --namespace kb-system --create-namespace --version <VERSION>
Verify whether this Addon is installed.
The STATUS is deployed
and this Addon is installed successfully.
helm list -A
>
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
...
kb-addon-es kb-system 1 2024-11-27 10:04:59.730127 +0800 CST deployed elasticsearch-0.9.0 8.8.2
(Optional) You can run the command below to uninstall the Addon.
If you have created a related cluster, delete the cluster first.
helm uninstall kb-addon-es --namespace kb-system
View the index.
kbcli creates an index named kubeblocks
by default and you can check whether this index is created by running kbcli addon index list
.
kbcli addon index list
>
INDEX URL
kubeblocks https://github.com/apecloud/block-index.git
If the list is empty or you want to add your index, you can add the index manually by using kbcli addon index add <index-name> <source>
. For example,
kbcli addon index add kubeblocks https://github.com/apecloud/block-index.git
If you are not sure whether the kubeblocks index is the latest version, you can update it.
kbcli addon index update kubeblocks
(Optional) Search whether the Addon exists in the index.
kbcli addon search elasticsearch
>
ADDON VERSION INDEX
elasticsearch 0.7.0 kubeblocks
elasticsearch 0.7.1 kubeblocks
elasticsearch 0.7.2 kubeblocks
elasticsearch 0.8.0 kubeblocks
elasticsearch 0.9.0 kubeblocks
Install the Addon.
If there are multiple index sources and versions for an Addon, you can specify an index by --index
and a version by --version
. The system installs the latest version in the kubeblocks
index by default.
kbcli addon install elasticsearch --index kubeblocks --version <VERSION>
Verify whether this Addon is installed.
The STATUS is Enabled
and this Addon is installed successfully.
kbcli addon list
>
NAME VERSION PROVIDER STATUS AUTO-INSTALL
elasticsearch 0.9.0 apecloud Enabled true
(Optional) You can run the command below to disable the Addon.
If you have created a related cluster, delete the cluster first.
kbcli addon disable elasticsearch
Or you can run the command below to uninstall the Addon.
kbcli addon uninstall elasticsearch
kbcli supports enable/disable an Addon. You can enable/disable Addons according to your need.
Moreover, when installing KubeBlocks by kbcli, some Addons are installed but remain disabled by default, with their status shown as Disabled
. You can enable them by kbcli. For example,
kbcli addon enable qdrant
kbcli addon disable qdrant
After enabling/disabling an Addon, check the Addon list to verify whether the Addon's status changes as required.
