Dify version

0.14.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Start Dify v0.14.0 using Docker Compose.

✔️ Expected Behavior

Ports should not be exposed unnecessarily. If it is necessary to expose a port, users should be able to change the port number. Containers that are not required for production environments should not be started.

❌ Actual Behavior

The tidb container is started regardless of the profile, and port 4000 is exposed. If port 4000 is already in use, an error occurs.

dify/docker/docker-compose.yaml

Lines 496 to 504 in 7f095bd

	# The TiDB vector store.
	# For production use, please refer to https://github.com/pingcap/tidb-docker-compose
	tidb:
	image: pingcap/tidb:v8.4.0
	ports:
	- "4000:4000"
	command:
	- --store=unistore
	restart: always

This behavior was introduced by #11645.

Workarounds

Without modifying the docker-compose.yaml file, you can use the --scale option to prevent the tidb container from starting:

docker compose up -d --scale tidb=0

To prevent the tidb container from exposing port 4000 in the Docker Compose setup for Dify v0.14.0, you can modify the docker-compose.yaml file. Specifically, you should comment out or remove the line that maps port 4000 in the tidb service configuration:

tidb:
  image: pingcap/tidb:v8.4.0
  # Comment out or remove the following line to not expose port 4000
  # ports:
  #   - "4000:4000"
  command:
    - --store=unistore
  restart: always

By doing this, the tidb container will not expose port 4000 to the host, which should help avoid conflicts if port 4000 is already in use ^[1].

Additionally, if you want to prevent the tidb container from starting in certain profiles, you might need to adjust the Docker Compose setup to include profile-specific configurations. However, the current setup does not provide a specific profile to exclude tidb, so you may need to manually manage this by editing the docker-compose.yaml file or using environment variables to control which services are started.
