Install MariaDB Addon for Stash
Stash uses Function-Task
model to backup databases. This Function-Task
model enables Stash to extend its capability via addons. In order to backup MariaDB databases, you have to install MariaDB addon (stash-mariadb
) for Stash. This addon creates necessary Function
and Task
definitions to backup/restore MariaDB database.
You can install the addon either as a helm chart or you can create only the YAMLs of the respective resources.
Using Helm 3
Run the following script to install stash-mariadb
addon as a Helm chart using Helm 3.
curl -fsSL https://github.com/stashed/catalog/raw/v2021.03.08/deploy/helm3.sh | bash -s -- --catalog=stash-mariadb
Using Helm 2
Run the following script to install stash-mariadb
addon as a Helm chart using Helm 2.
curl -fsSL https://github.com/stashed/catalog/raw/v2021.03.08/deploy/helm2.sh | bash -s -- --catalog=stash-mariadb
Using YAML
Run the following script to install stash-mariadb
addon as Kubernetes YAMLs.
curl -fsSL https://github.com/stashed/catalog/raw/v2021.03.08/deploy/script.sh | bash -s -- --catalog=stash-mariadb
The above script uses Helm 3 for rendering the charts to generate the YAMLs.
Verify Installation
After installation is completed, this addon will create mariadb-backup-*
and mariadb-restore-*
Functions and Tasks for all supported MariaDB versions. To verify, run the following command:
$ kubectl get functions.stash.appscode.com
NAME AGE
mariadb-backup-10.5.8 25s
mariadb-restore-10.5.8 25s
pvc-backup 3m14s
pvc-restore 3m14s
update-status 3m14s
Also, verify that the Task
have been created.
$ kubectl get tasks.stash.appscode.com
NAME AGE
mariadb-backup-10.5.8 101s
mariadb-restore-10.5.8 101s
pvc-backup 4m30s
pvc-restore 4m30s
Now, Stash is ready to backup MariaDB databases.

In order to install Function
and Task
only for a specific MariaDB version, use --version
flag to specify the desired database version.
