# MariaDB
[MariaDB](https://mariadb.org) is one of the most popular database servers in the world. It’s made by the original developers of MySQL and guaranteed to stay open source. Notable users include Wikipedia, Facebook and Google.
MariaDB is developed as open source software and as a relational database it provides an SQL interface for accessing data. The latest versions of MariaDB also include GIS and JSON features.
## TL;DR
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/mariadb
```
## Introduction
This chart bootstraps a [MariaDB](https://github.com/bitnami/bitnami-docker-mariadb) replication cluster deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the [BKPR](https://kubeprod.io/).
## Prerequisites
- Kubernetes 1.12+
- Helm 2.12+ or Helm 3.0-beta3+
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```bash
$ helm install my-release bitnami/mariadb
```
The command deploys MariaDB on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```bash
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
## Parameters
The following table lists the configurable parameters of the MariaDB chart and their default values.

The above parameters map to the env variables defined in [bitnami/mariadb](http://github.com/bitnami/bitnami-docker-mariadb). For more information please refer to the [bitnami/mariadb](http://github.com/bitnami/bitnami-docker-mariadb) image documentation.
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```bash
$ helm install my-release \
--set rootUser.password=secretpassword,db.user=app_database \
bitnami/mariadb
```
The above command sets the MariaDB `root` account password to `secretpassword`. Additionally it creates a database named `my_database`.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```bash
$ helm install my-release -f values.yaml bitnami/mariadb
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Production configuration
This chart includes a `values-production.yaml` file where you can find some parameters oriented to production configuration in comparison to the regular `values.yaml`. You can use this file instead of the default one.
- Force users to specify a password and mount secrets as volumes instead of using environment variables:
```diff
- rootUser.forcePassword: false
- rootUser.injectSecretsAsVolume: false
+ rootUser.forcePassword: true
+ rootUser.injectSecretsAsVolume: true
- db.forcePassword: false
- db.injectSecretsAsVolume: false
+ db.forcePassword: true
+ db.injectSecretsAsVolume: true
- replication.forcePassword: false
- replication.injectSecretsAsVolume: false
+ replication.forcePassword: true
+ replication.injectSecretsAsVolume: true
```
- Desired number of slave replicas:
```diff
- slave.replicas: 1
+ slave.replicas: 2
```
- Start a side-car prometheus exporter:
```diff
- metrics.enabled: false
+ metrics.enabled: true
```
### Change MariaDB version
To modify the MariaDB version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/mariadb/tags/) using the `image.tag` parameter. For example, `image.tag=X.Y.Z`. This approach is also applicable to other images like exporters.
### Initialize a fresh instance
The [Bitnami MariaDB](https://github.com/bitnami/bitnami-docker-mariadb) image allows you to use your custom scripts to initialize a fresh instance. In order to execute the scripts, they must be located inside the chart folder `files/docker-entrypoint-initdb.d` so they can be consumed as a ConfigMap.
Alternatively, you can specify custom scripts using the `initdbScripts` parameter as dict.
In addition to these options, you can also set an external ConfigMap with all the initialization scripts. This is done by setting the `initdbScriptsConfigMap` parameter. Note that this will override the two previous options.
The allowed extensions are `.sh`, `.sql` and `.sql.gz`.
### Extra Init Containers
The feature allows for specifying a template string for a initContainer in the master/slave pod. Usecases include situations when you need some pre-run setup. For example, in IKS (IBM Cloud Kubernetes Service), non-root users do not have write permission on the volume mount path for NFS-powered file storage. So, you could use a initcontainer to `chown` the mount. See a example below, where we add an initContainer on the master pod that reports to an external resource that the db is going to starting.
`values.yaml`
```yaml
master:
extraInitContainers: |
- name: initcontainer
image: bitnami/minideb:buster
command: ["/bin/sh", "-c"]
args:
- install_packages curl && curl http://api-service.local/db/starting;
```
## Persistence
The [Bitnami MariaDB](https://github.com/bitnami/bitnami-docker-mariadb) image stores the MariaDB data and configurations at the `/bitnami/mariadb` path of the container.
The chart mounts a [Persistent Volume](https://kubernetes.io/docs/user-guide/persistent-volumes/) volume at this location. The volume is created using dynamic volume provisioning, by default. An existing PersistentVolumeClaim can be defined.
### Adjust permissions of persistent volume mountpoint
As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
You can enable this initContainer by setting `volumePermissions.enabled` to `true`.
## Upgrading
It's necessary to set the `rootUser.password` parameter when upgrading for readiness/liveness probes to work properly. When you install this chart for the first time, some notes will be displayed providing the credentials you must use under the 'Administrator credentials' section. Please note down the password and run the command below to upgrade your chart:
```bash
$ helm upgrade my-release bitnami/mariadb --set rootUser.password=[ROOT_PASSWORD]
```
| Note: you need to substitute the placeholder _[ROOT_PASSWORD]_ with the value obtained in the installation notes.
### To 7.0.0
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In https://github.com/helm/charts/pull/17308 the `apiVersion` of the statefulset resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.
This major version bump signifies this change.
### To 6.0.0
MariaDB version was updated from 10.1 to 10.3, there are no changes in the chart itself. According to the official documentation, upgrading from 10.1 should be painless. However, there are some things that have changed which could affect an upgrade:
- [Incompatible changes upgrading from MariaDB 10.1 to MariaDB 10.2](https://mariadb.com/kb/en/library/upgrading-from-mariadb-101-to-mariadb-102//#incompatible-changes-between-101-and-102)
- [Incompatible changes upgrading from MariaDB 10.2 to MariaDB 10.3](https://mariadb.com/kb/en/library/upgrading-from-mariadb-102-to-mariadb-103/#incompatible-changes-between-102-and-103)
### To 5.0.0
Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 5.0.0. The following example assumes that the release name is mariadb:
```console
$ kubectl delete statefulset opencart-mariadb --cascade=false
```
