+# 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.
+
+## This Helm chart is deprecated
+
+Given the [`stable` deprecation timeline](https://github.com/helm/charts#deprecation-timeline), the Bitnami maintained MariaDB Helm chart is now located at [bitnami/charts](https://github.com/bitnami/charts/).
+
+The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the _bitnami_ repo and using it during the installation (`bitnami/<chart>` instead of `stable/<chart>`)
+
+```bash
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm install my-release bitnami/<chart>           # Helm 3
+$ helm install --name my-release bitnami/<chart>    # Helm 2
+```
+
+To update an exisiting _stable_ deployment with a chart hosted in the bitnami repository you can execute
+
+```bash
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm upgrade my-release bitnami/<chart>
+```
+
+Issues and PRs related to the chart itself will be redirected to `bitnami/charts` GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in [this issue](https://github.com/helm/charts/issues/20969) created as a common place for discussion.
+
+## TL;DR;
+
+```bash
+$ helm install my-release stable/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 2.11+ 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 stable/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 \
+    stable/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 stable/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
+```
+
+### 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](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 stable/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
+```

+This Helm chart is deprecated
+
+Given the `stable` deprecation timeline (https://github.com/helm/charts#deprecation-timeline), the Bitnami maintained Helm chart is now located at bitnami/charts (https://github.com/bitnami/charts/).
+
+The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the _bitnami_ repo and using it during the installation (`bitnami/<chart>` instead of `stable/<chart>`)
+
+```bash
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm install my-release bitnami/<chart>           # Helm 3
+$ helm install --name my-release bitnami/<chart>    # Helm 2
+```
+
+To update an exisiting _stable_ deployment with a chart hosted in the bitnami repository you can execute
+
+```bash
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm upgrade my-release bitnami/<chart>
+```
+
+Issues and PRs related to the chart itself will be redirected to `bitnami/charts` GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in this issue (https://github.com/helm/charts/issues/20969) created as a common place for discussion.
+
+Please be patient while the chart is being deployed
+
+Tip:
+
+  Watch the deployment status using the command: kubectl get pods -w --namespace {{ .Release.Namespace }} -l release={{ .Release.Name }}
+
+Services:
+
+  echo Master: {{ template "mariadb.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local:{{ .Values.service.port }}

+
+  Username: root
+  Password : $(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mariadb.secretName" . }} -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
+
+To connect to your database:
+
+  1. Run a pod that you can use as a client:
+
+      kubectl run {{ template "mariadb.fullname" . }}-client --rm --tty -i --restart='Never' --image  {{ template "mariadb.image" . }} --namespace {{ .Release.Namespace }} --command -- bash
+
+  2. To connect to master service (read/write):
+
+      mysql -h {{ template "mariadb.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local -uroot -p {{ .Values.db.name }}
+
+{{- if .Values.replication.enabled }}
+
+  3. To connect to slave service (read-only):
+
+      mysql -h {{ template "slave.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local -uroot -p {{ .Values.db.name }}
+{{- end }}
+
+To upgrade this helm chart:
+
+  1. Obtain the password as described on the 'Administrator credentials' section and set the 'rootUser.password' parameter as shown below:
+
+      ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mariadb.secretName" . }} -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
+      helm upgrade {{ .Release.Name }} stable/mariadb --set rootUser.password=$ROOT_PASSWORD

+# ⚠️ Repo Archive Notice
+
+As of Nov 13, 2020, charts in this repo will no longer be updated.
+For more information, see the Helm Charts [Deprecation and Archive Notice](https://github.com/helm/charts#%EF%B8%8F-deprecation-and-archive-notice), and [Update](https://helm.sh/blog/charts-repo-deprecation/).
+
+# MySQL
+
+[MySQL](https://MySQL.org) is one of the most popular database servers in the world. Notable users include Wikipedia, Facebook and Google.
+
+## DEPRECATION NOTICE
+
+This chart is deprecated and no longer supported.
+
+## Introduction
+
+This chart bootstraps a single node MySQL deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes 1.10+ with Beta APIs enabled
+- PV provisioner support in the underlying infrastructure
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+$ helm install --name my-release stable/mysql
+```
+
+The command deploys MySQL on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+By default a random password will be generated for the root user. If you'd like to set your own password change the mysqlRootPassword
+in the values.yaml.
+
+You can retrieve your root password by running the following command. Make sure to replace [YOUR_RELEASE_NAME]:
+
+    printf $(printf '\%o' `kubectl get secret [YOUR_RELEASE_NAME]-mysql -o jsonpath="{.data.mysql-root-password[*]}"`)
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```bash
+$ helm delete --purge my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release completely.
+
+## Configuration
+
+The following table lists the configurable parameters of the MySQL chart and their default values.

+
+Some of the parameters above map to the env variables defined in the [MySQL DockerHub image](https://hub.docker.com/_/mysql/).
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install --name my-release \
+  --set mysqlRootPassword=secretpassword,mysqlUser=my-user,mysqlPassword=my-password,mysqlDatabase=my-database \
+    stable/mysql
+```
+
+The above command sets the MySQL `root` account password to `secretpassword`. Additionally it creates a standard database user named `my-user`, with the password `my-password`, who has access to 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 --name my-release -f values.yaml stable/mysql
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Persistence
+
+The [MySQL](https://hub.docker.com/_/mysql/) image stores the MySQL data and configurations at the `/var/lib/mysql` path of the container.
+
+By default a PersistentVolumeClaim is created and mounted into that directory. In order to disable this functionality
+you can change the values.yaml to disable persistence and use an emptyDir instead.
+
+> *"An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever."*
+
+**Notice**: You may need to increase the value of `livenessProbe.initialDelaySeconds` when enabling persistence by using PersistentVolumeClaim from PersistentVolume with varying properties. Since its IO performance has impact on the database initialization performance. The default limit for database initialization is `60` seconds (`livenessProbe.initialDelaySeconds` + `livenessProbe.periodSeconds` * `livenessProbe.failureThreshold`). Once such initialization process takes more time than this limit, kubelet will restart the database container, which will interrupt database initialization then causing persisent data in an unusable state.
+
+## Custom MySQL configuration files
+
+The [MySQL](https://hub.docker.com/_/mysql/) image accepts custom configuration files at the path `/etc/mysql/conf.d`. If you want to use a customized MySQL configuration, you can create your alternative configuration files by passing the file contents on the `configurationFiles` attribute. Note that according to the MySQL documentation only files ending with `.cnf` are loaded.
+
+```yaml
+configurationFiles:
+  mysql.cnf: |-
+    [mysqld]
+    skip-host-cache
+    skip-name-resolve
+    sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
+  mysql_custom.cnf: |-
+    [mysqld]
+```
+
+## MySQL initialization files
+
+The [MySQL](https://hub.docker.com/_/mysql/) image accepts *.sh, *.sql and *.sql.gz files at the path `/docker-entrypoint-initdb.d`.
+These files are being run exactly once for container initialization and ignored on following container restarts.
+If you want to use initialization scripts, you can create initialization files by passing the file contents on the `initializationFiles` attribute.
+
+
+```yaml
+initializationFiles:
+  first-db.sql: |-

+## SSL
+
+This chart supports configuring MySQL to use [encrypted connections](https://dev.mysql.com/doc/refman/5.7/en/encrypted-connections.html) with TLS/SSL certificates provided by the user. This is accomplished by storing the required Certificate Authority file, the server public key certificate, and the server private key as a Kubernetes secret. The SSL options for this chart support the following use cases:
+
+* Manage certificate secrets with helm
+* Manage certificate secrets outside of helm
+
+## Manage certificate secrets with helm
+
+Include your certificate data in the `ssl.certificates` section. For example:
+
+```
+ssl:
+  enabled: false
+  secret: mysql-ssl-certs
+  certificates:
+  - name: mysql-ssl-certs
+    ca: |-
+      -----BEGIN CERTIFICATE-----
+      ...
+      -----END CERTIFICATE-----
+    cert: |-
+      -----BEGIN CERTIFICATE-----
+      ...
+      -----END CERTIFICATE-----
+    key: |-
+      -----BEGIN RSA PRIVATE KEY-----
+      ...
+      -----END RSA PRIVATE KEY-----
+```
+
+> **Note**: Make sure your certificate data has the correct formatting in the values file.
+
+## Manage certificate secrets outside of helm
+
+1. Ensure the certificate secret exist before installation of this chart.
+2. Set the name of the certificate secret in `ssl.secret`.
+3. Make sure there are no entries underneath `ssl.certificates`.
+
+To manually create the certificate secret from local files you can execute:
+```
+kubectl create secret generic mysql-ssl-certs \
+  --from-file=ca.pem=./ssl/certificate-authority.pem \
+  --from-file=server-cert.pem=./ssl/server-public-key.pem \
+  --from-file=server-key.pem=./ssl/server-private-key.pem
+```
+> **Note**: `ca.pem`, `server-cert.pem`, and `server-key.pem` **must** be used as the key names in this generic secret.
+
+If you are using a certificate your configurationFiles must include the three ssl lines under [mysqld]
+
+```
+[mysqld]
+    ssl-ca=/ssl/ca.pem
+    ssl-cert=/ssl/server-cert.pem
+    ssl-key=/ssl/server-key.pem
+```
