# MySQL
|
|
|
|
DataHub GMS uses MySQL as the storage infrastructure.
|
|
[Official MySQL Docker image](https://hub.docker.com/_/mysql) found in Docker Hub is used without
|
|
any modification.
|
|
|
|
## Run Docker container
|
|
Below command will start the MySQL container.
|
|
```
|
|
cd docker/mysql && docker-compose pull && docker-compose up
|
|
```
|
|
|
|
An initialization script [init.sql](init.sql) is provided to container. This script initializes `metadata-aspect` table
|
|
which is basically the Key-Value store of the DataHub GMS.
|
|
|
|
To connect to MySQL container, you can type below command:
|
|
```
|
|
docker exec -it mysql mysql -u datahub -pdatahub datahub
|
|
```
|
|
|
|
## Container configuration
|
|
### External Port
|
|
If you need to configure default configurations for your container such as the exposed port, you will do that in
|
|
`docker-compose.yml` file. Refer to this [link](https://docs.docker.com/compose/compose-file/#ports) to understand
|
|
how to change your exposed port settings.
|
|
```
|
|
ports:
|
|
- '3306:3306'
|
|
```
|
|
|
|
### Docker Network
|
|
All Docker containers for DataHub are supposed to be on the same Docker network which is `datahub_network`.
|
|
If you change this, you will need to change this for all other Docker containers as well.
|
|
```
|
|
networks:
|
|
default:
|
|
name: datahub_network
|
|
``` |
