# How to configure GRAVITY and Docker containers
GRAVITY builds are available on [Docker Hub](https://hub.docker.com/?namespace=gravityglobaldev "https://hub.docker.com/?namespace=gravityglobaldev") as private repositories. Please contact us to get your Access Token.
Helm Charts are available on request.
There are three version available:
- [Test/POC-Version](https://hub.docker.com/repository/docker/gravityglobaldev/gravity "https://hub.docker.com/repository/docker/gravityglobaldev/gravity") with GRAVITY application server & MariaDB on combined in one container
- [MariaDB-Version](https://hub.docker.com/repository/docker/gravityglobaldev/gravity-server "https://hub.docker.com/repository/docker/gravityglobaldev/gravity-server") of the GRAVITY application server
- [Oracle DB-Version](https://hub.docker.com/repository/docker/gravityglobaldev/gravity-server-oracle "https://hub.docker.com/repository/docker/gravityglobaldev/gravity-server-oracle") of the GRAVITY application server
- [PostgreSQL DB-Version](https://hub.docker.com/repository/docker/gravityglobaldev/gravity-server-postgres "https://hub.docker.com/repository/docker/gravityglobaldev/gravity-server-postgres") of the GRAVITY application server
> [!Info]
> There is an empty [MariaDB in a Docker Container](https://hub.docker.com/repository/docker/gravityglobaldev/gravity-db "https://hub.docker.com/repository/docker/gravityglobaldev/gravity-db") on the Docker Hub. That container can be used with the MariaDB-Version of GRAVITY.
> [!Info]
> To import private certificates; mount the “/ca-certificates” folder with *.pem file(s) to the deployed container.
## Usage with Docker Compose
1. Install [Docker Engine](https://docs.docker.com/engine/install/ "https://docs.docker.com/engine/install/")
2. Install [Docker Compose](https://docs.docker.com/compose/install/ "https://docs.docker.com/compose/install/")
3. Login to Docker Hub, at the password prompt, enter the personal Access Token provided.
`docker login -u gravityglobal`
4. Create docker-compose.yml
5. Start the container: docker-compose up -d
General template of docker-compose.yml
```

- SPRING_DATASOURCE_USERNAME=%DB_USERNAME%
- SPRING_DATASOURCE_PASSWORD=%DB_PASSWORD%
ports:
- "8080:8080"
restart: 'always'
```
Example of docker-compose.yml (Oracle version)
