Improve `file-service` Docker Compose File

[AnzhiZhang]

Proposed Changes

It might be good to improve the Docker Compose file for LakeFS in our file-service. To be specific:

1. Remove version. In the current version of Docker Compose, the version is obsolete. We are not including this in the single node installation compose file. See https://docs.docker.com/reference/compose-file/version-and-name/
2. Update container_name. Currently, we have minio, postgres, and lakefs as container names. However, this name is globally on a machine. We should give a namespace to avoid collisions and inconvenience. Similarly to what we did in the single node configuration, I propose texera-lakefs-minio and the others.
3. Give default volumes. Currently, minio and postgres data are persisted using auto-created Docker volumes, which will be a generated hash name. We have a comment in the Docker Compose file to help developers assign a physical location to persist them. We can set default volumes like minio_data to better persist data and prevent loss.

Changes for Developers to Apply

After this change, developers need to:

• Clone those auto-generated volumes to the new name.
• Recreate containers.

Here is a step-by-step guide:

1. Go to core/file-service/src/main/resources.
2. Stop and remove containers.

docker compose down

3. Merge main to your local branch.
4. Start containers.

docker compose up -d

5. Stop containers.

docker compose stop

6. Copy volumes. Replace two volume names only. New volume names are texera-lakefs_postgres_data and texera-lakefs_minio_data. The old volume name is generated volume name, it looks like 68bbd428f6a7331a964df929b1effa0837a14f451a5eeb18e0f96d6736471ed8.

docker run --rm \
  --volume ${OLD_VOLUME_NAME}:/source \
  --volume ${NEW_VOLUME_NAME}:/destination \
  ubuntu:latest \
  bash -c "echo 'copying volume ...'; cp -Rp /source/* /destination/"

Command from: https://stackoverflow.com/a/74953859/19420247

Note: If you are using Docker Desktop, you can use the "Clone" button in the volumes tab to simply complete this step.

7. Start containers.

docker compose up -d
