Dify version

0.15.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

1. Configure envs to use external database, redis and storage (S3).
2. Remove all container's volume
3. Restart containers

✔️ Expected Behavior

I am hosting Dify on an EC2 instance using Docker Compose and deploying it via a Bitbucket pipeline. In my pipeline, I essentially remove all Dify-related files from the server, redeploy the application, stop the containers, and then start them again.

I've already externalized some environment variables to connect to an external database, S3 storage, and Redis. However, after each redeploy, when I try to perform a retrieval test through the front end, I encounter a "GraphQL schema not found" error. The issue resolves if I deactivate and reactivate the document, but this isn't ideal.

My question is: how can I make this process more reliable so that, even after a redeploy, the system continues to work with the existing data without issues? What might I be overlooking?

❌ Actual Behavior

Some graphql is not created when containers are restarted

Query was not successful! Unexpected status code: 422, with response body: {'error': [{'message': 'no graphql provider present, this is most likely because no schema is present. Import a schema first!'}]}.; Query was not successful! Unexpected status code: 422, with response body: {'error': [{'message': 'no graphql provider present, this is most likely because no schema is present. Import a schema first!'}]}.

I found a similar unsolved discussion titled "Self hosting problem after rebooting machine" on the Dify GitHub repository. You can view it here ^[1].

Regarding your issue, it seems that the GraphQL schema is not being retained across container restarts. To address this, ensure that your Docker volumes for the database and other services are correctly configured to persist data. Specifically, mark the database volume as external in your docker-compose.yaml file to prevent it from being removed during docker compose down operations ^[2].

Additionally, verify that your environment variables are correctly set to point to the external services and that these services are accessible and properly configured. This setup should help maintain the GraphQL schema and other data across redeployments.
