+# [`mariadb-agent`](https://github.com/mariadb/mariadb)
+
+## Prerequisites
+
+- Kubernetes 1.19+
+- Helm 3.2.0+
+
+## Preflight checklist
+
+## How to add repo
+
+Add the repo to your local helm client.
+
+```sh
+helm repo add mika https://irfanhakim-as.github.io/charts
+```
+
+Update the repo to retrieve the latest versions of the packages.
+
+```sh
+helm repo update
+```
+
+## How to install
+
+### Prepare MariaDB host
+
+Install [`bitnami/mariadb`](https://github.com/bitnami/charts/tree/main/bitnami/mariadb). This step can be skipped if you have an existing MariaDB server.
+
+### Prepare chart values
+
+Copy `values.yaml` from the chart you would like to install. Refer to the [Configurations](#configurations) section for more information.
+
+```sh
+cp mika/mariadb-agent/values.yaml .
+```
+
+Edit `values.yaml` with the appropriate values. Refer to the [Configurations](#Configurations) section for available options.
+
+```sh
+nano values.yaml
+```
+
+### Perform installation
+
+Install the desired chart. Replace `$release_name` and `$namespace` accordingly.
+
+```sh
+helm install $release_name mika/mariadb-agent --namespace $namespace --create-namespace --values values.yaml --wait
+```
+
+Verify that your chart has been installed. Replace `$namespace` and `$release_name` accordingly.
+
+```sh
+helm ls --namespace $namespace | grep "$release_name"
+```
+
+## How to upgrade
+
+After making any necessary changes to the `values.yaml` file, upgrade the desired chart. Replace `$release_name` and `$namespace` accordingly.
+
+```sh
+helm upgrade $release_name mika/mariadb-agent --namespace $namespace --values values.yaml --wait
+```
+
+## How to uninstall
+
+Uninstall the desired chart. Replace `$release_name` and `$namespace` accordingly.
+
+```sh
+helm uninstall $release_name --namespace $namespace --wait
+```
+
+## Configurations
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| image.mariadb.pullPolicy | string | `""` | The policy that determines when Kubernetes should pull the MariaDB container image. Default: `"IfNotPresent"`. |
+| image.mariadb.registry | string | `""` | The registry where the MariaDB container image is hosted. Default: `"docker.io"`. |
+| image.mariadb.repository | string | `""` | The name of the repository that contains the MariaDB container image used. Default: `"bitnami/mariadb"`. |
+| image.mariadb.tag | string | `""` | The tag that specifies the version of the MariaDB container image used. Default: `Chart appVersion`. |
+| mariadb.databases | list | `[]` | Database configurations array. Elements: `.name`, `.user`, `.password`, `.create`, `.drop`, `.custom_command`. |
+| mariadb.host | string | `""` | The hostname or IP address of the MariaDB database server. |
+| mariadb.root.password | string | `""` | The password associated with the MariaDB database server root user. |
+| mariadb.root.user | string | `""` | The username or user account for accessing the MariaDB database server as root. Default: `"root"`. |
