Issue related docker containers connectivity

Hi,

1. Check MySQL Container Status: Ensure that your MySQL container is up and running. You can use the docker ps command to list all running containers.

2)Verify MySQL Configuration: 

Check the MySQL configuration inside the container. Make sure the MySQL server is listening on the correct interface and port. You might need to expose the MySQL port from the container to the host machine if it's not already done.

Check Connection Parameters: Ensure that the connection parameters in your application or MySQL client are correctly configured to connect to the MySQL server running inside the Docker container. If you're trying to connect from another container, ensure that the containers are on the same Docker network.

3) Check for Container Network Configuration: Ensure that the containers are on the same Docker network, especially if you're trying to establish communication between different containers. Docker networks provide isolation by default, so containers connected to different networks won't be able to communicate directly.

4)Verify Docker Network Settings: 

Check the Docker network settings to ensure that there are no misconfigurations or conflicts. You can use commands like docker network ls and docker network inspect <network_name> to get more information about the Docker networks.

5)Inspect MySQL Container Logs:

Check the logs of the MySQL container to see if there are any errors or warnings that might indicate why the MySQL server is not accessible. You can use the docker logs <container_id> command to view the logs.

6)Check Firewall Rules:

Ensure that there are no firewall rules blocking the connection between the MySQL client and server. If you're running a firewall on your host machine or within Docker containers, make sure it allows traffic on the MySQL port (default is 3306).

7)Restart Docker Services: 

Sometimes, restarting Docker services or even the host machine can resolve networking issues related to Docker containers.
