note
The upgrade feature means that KubeBlocks supports minor version upgrades for a database engine. For example, you can upgrade PostgreSQL from v12.14 to v12.15.
Use addons
Use the index to install an addon
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, add addons first by index.
The official index repo is KubeBlocks index. The code of all addons is maintained in the KubeBlocks addon repo.
View the index.
kbcli creates an index named
kubeblocksby default and you can check whether this index is created by runningkbcli addon index list.kbcli addon index list
>
INDEX URL
kubeblocks https://github.com/apecloud/block-index.gitIf 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(Optional) Search whether the addon exists in the index.
kbcli addon search mariadb
>
ADDON VERSION INDEX
mariadb 0.7.0 kubeblocksInstall the addon.
If there are multiple index sources and versions for an addon, you can specify them by adding flags. The system installs the latest version in the
kubeblocksindex by default.kbcli addon install mariadb --index kubeblocks --version 0.7.0What's next
After the addon is installed, you can list and enable it.
List addons
To list supported addons, run kbcli addon list command.
Enable/Disable addons
To manually enable or disable addons, follow the steps below.
Steps:
To enable an addon, use
kbcli addon enable.Example
kbcli addon enable snapshot-controllerTo disable an addon, use
kbcli addon disable.List the addons again to check whether it is enabled.
