Troubleshooting

Common Issues

SeaTunnel Web Starts Without Shared Connectors

Ensure the shared-connectors volume is correctly mounted and populated:

bash

Copy code

docker exec -it seatunnel_web ls /shared-connectors

MySQL Connection Issues

Verify the MYSQL_HOST and MYSQL_PORT variables in the docker-compose.yml file match the MySQL container's IP and port.

Cache Issues

If updates are not reflected, clear Docker caches:

bash

Copy code

docker-compose down docker-compose build --no-cache

File Permissions

Ensure the entrypoint.sh script is executable:

bash

Copy code

chmod +x seatunnel-web/entrypoint.sh
