Hello, @chloroplast47! I'm here to help you with any bugs, questions, or contributions you have for the repository. Let's work together to solve this issue.

To resolve the issue with your docker-db-1 container, which cannot be started successfully and always restarts, you can follow these steps:

Check Container Logs: First, inspect the logs of the docker-db-1 container to identify the root cause of the issue. You can do this by running:
```
docker logs docker-db-1
```
Verify Environment Variables: Ensure that the environment variables in your .env file are correctly set, especially those related to the database configuration. The required variables are:
```
DB_USERNAME=postgres
DB_PASSWORD=difyai123456
DB_DATABASE=dify
DB_HOST=db
DB_PORT=5432
```
Check Resource Allocation: Make sure that your Docker virtual machine (VM) has sufficient resources allocated. For macOS, it should have a minimum of 2 virtual CPUs (vCPUs) and 8 GB of initial memory.
Restart the Container: If the issue persists, try restarting the container:
```
docker compose restart db
```
Recreate the Container: If restarting does not help, you may need to recreate the container:
```
docker compose down
docker compose up -d
```

Upgrade Dify: Ensure you are using the latest version of Dify by upgrading it:

cd dify/docker
git pull origin main
docker compose down
docker compose pull
docker compose up -d

Check WSL2 Configuration (if on Windows): If you are using Windows, ensure that WSL2 is properly configured as Dify's docker deployment recommends using WSL2. Follow these steps:
- Install WSL2 by running the following command in an elevated CMD:
```
wsl --install
```
- Install Docker Desktop and ensure the Use WSL 2 instead of Hyper-V option is checked during installation.
- Verify that WSL2 and Docker are running correctly:
```
wsl -l --verbose
```

By following these steps, you should be able to identify and resolve the issue with your docker-db-1 container ^[1]^[2]^[3].
