## Docker Volumes
|
|
Advance section
|
|
|
|
|
|
Volumes provide the ability to connect specific filesystem paths of the container back to the host machine. If a directory or a file in the container is mounted, changes in that directory or file can also be seen on the host machine.we are going to use a mapping of a directory present on the host macine with the container path.
|

<Note>

|
|
|
To make changes to the `docker-compose.yaml` file you will need to download it from the release page [here](https://github.com/open-metadata/OpenMetadata/releases). The latest version is at the top of the page

volumes:

|
|
- ./docker-volume/dags:/opt/airflow/dags
|
|
- ./docker-volume/secrets:/tmp
|
|
...
|
|
```
|
|
|
|
Once these changes are done in the docker-compose.yml file It should look simlarly in the below format
|
|
|
|
```commandline
|
|
version: "3.9"
|
|
services:
|
|
mysql:
|
|
container_name: openmetadata_mysql
|
|
image: openmetadata/db:0.13.0
|
|
restart: always
|
|
environment:
|
|
MYSQL_ROOT_PASSWORD: password
|
|
expose:
|
|
- 3306
|
|
volumes:
|
|
- ./docker-volume/db:/var/lib/mysql
|
|
networks:
|
|
app_net:
|
|
ipv4_address: 172.16.240.10
|
|
ingestion:
|
|
container_name: openmetadata_ingestion
|
|
image: openmetadata/ingestion:0.13.0
|
|
depends_on:
|
|
- mysql
|
|
expose:
|
|
- 8080
|
|
ports:
|
|
- 8080:8080
|
|
networks:
|
|
- app_net
|
|
extra_hosts:
|
|
- "localhost:172.16.240.10"
|
|
- "localhost:172.16.240.11"
|
|
- "localhost:172.16.240.13"
|
|
volumes:
|
|
- ./docker-volume/dag_config:/opt/airflow/dag_generated_configs
|
|
- ./docker-volume/dags:/opt/airflow/dags
|
|
- ./docker-volume/secrets:/tmp
|
|
```
|
|
|
|
Once these changes are done, restart the container via:
|
|
|
|
```commandline
|
|
docker compose down && docker compose up -d
|
|
```
|
|
<Note>
|
|
If you are starting the OpenMetadata Docker containers using below command:
|
|
```command line
|
|
metadata docker --start
|
|
```
|
|
Then the docker volume directory will be created under the folder where the docker-compose file will be present.
