## About
This will build a Docker image for [MariaDB](https://mariadb.org). A relational database forked from MySQL.
* Configuration tweaked to use all around settings for general usage - Can be changed
* Can use official Mysql/MariaDB environment variables (MYSQL_USER, MYSQL_PASSWORD, MYSQL_ROOT_PASSWORD)
* Allows for automatically creating multiple databases on container initialization and subsequent reboots
* Automatic Table/DB Upgrade support if MariaDB version has changed
* Includes MySQL Tuner inside image to optimize your configuration
* Logging with automatic rotation
* Zabbix Monitoring for metrics
Also has the capability of backing up embedded in the container based on the [tiredofit/dbbackup](https://github.com/tiredofit/docker-db-backup) image which includes the following features:
* dump to local filesystem
* Backup all databases
* choose to have an MD5?SHA sum after backup for verification
* delete old backups after specific amount of time
* choose compression type (none, gz, bz, xz,zstd)
* select how often to run a dump
* select when to start the first dump, whether time of day or relative to container start time

## Installation
### Build from Source
Clone this repository and build the image with `docker build (imagename) .`
### Prebuilt Images
Builds of the image are available on [Docker Hub](https://hub.docker.com/r/tiredofit/mariadb)
```bash
docker pull docker.io/tiredofdit/mariadb:(imagetag)
```
Builds of the image are also available on the [Github Container Registry](https://github.com/tiredofit/docker-mariadb/pkgs/container/docker-mariadb)
```
docker pull ghcr.io/tiredofit/docker-mariadb:(imagetag)
```
The following image tags are available along with their tagged release based on what's written in the [Changelog](CHANGELOG.md):
| Version | Container OS | Tag |
| --------- | ------------ | --------- |
| latest | Alpine | `:latest` |
| `10.11.x` | Alpine | `:10.11` |
| `10.10.x` | Alpine | `:10.10` |
| `10.9.x` | Alpine | `:10.9` |
| `10.8.x` | Alpine | `:10.8` |
| `10.6.x` | Alpine | `:10.6` |
| `10.5.x` | Alpine | `:10.5` |
#### Multi Architecture
Images are built primarily for `amd64` architecture, and may also include builds for `arm/v7`, `arm64` and others. These variants are all unsupported. Consider [sponsoring](https://github.com/sponsors/tiredofit) my work so that I can work with various hardware. To see if this image supports multiple architecures, type `docker manifest (image):(tag)`
## Configuration
### Quick Start
* The quickest way to get started is using [docker-compose](https://docs.docker.com/compose/). See the examples folder for a working [compose.yml](examples/compose.yml) that can be modified for development or production use.
* Set various [environment variables](#environment-variables) to understand the capabilities of this image.
* Map [persistent storage](#data-volumes) for access to configuration and data files for backup.
- Make [networking ports](#networking) available for public access if necessary
### Persistent Storage
The following directories are used for configuration and can be mapped for persistent storage.
| Directory | Description |
| ------------------- | -------------------------------------------------------------- |
| `/var/lib/mysql` | MySQL Data Directory |
| `/etc/mysql/conf.d` | Optional directory to put .cnf files for additional directives |
| `/backup` | Optional directory for backups |
### Environment Variables
#### Base Images used
This image relies on an [Alpine Linux](https://hub.docker.com/r/tiredofit/alpine) base image that relies on an [init system](https://github.com/just-containers/s6-overlay) for added capabilities. Outgoing SMTP capabilities are handlded via `msmtp`. Individual container performance monitoring is performed by [zabbix-agent](https://zabbix.org). Additional tools include: `bash`,`curl`,`less`,`logrotate`,`nano`,`vim`.
Be sure to view the following repositories to understand all the customizable options:
