Fixing Windows Redis-Client Connection Issues to Docker Server

If you're using Windows 10 and trying to connect to a Redis container running on Docker, you may have encountered a frustrating connection error. Specifically, you might see a message that reads: "Could not connect to Redis at 192.168.99.1:6379: Unknown error." This problem can arise due to several factors, particularly the way the Docker container is configured and the ports that are being used.

In this guide, we will explore why this connection error occurs and provide a straightforward solution to help you connect your Redis client to a Redis Docker container seamlessly.

Understanding the Error

The error message indicates that the Redis client is unable to connect to the specified IP address and port. Several factors might cause this issue, such as:

The Redis container is not running or is not exposed to the correct port.

A firewall or network setting is blocking the connection.

The Redis service within the container is not configured properly.

Solution to Connect Redis Client to Docker

To resolve the connection issue, follow these steps carefully to ensure a smooth connection between your Redis client and the Redis Docker container.

Step 1: Start Redis Container with Correct Port Mapping

Instead of using the default Redis port (6379) without proper exposure, you should bind the Redis service to a different port on your host machine. This can be achieved by using the following command in your terminal:

Explanation:

-p 7000:6379: This command maps the host's port 7000 to the container's port 6379. By connecting to port 7000, you will be able to access the Redis service from your host machine.

-d redis redis-server: This keeps the Redis server running in detached mode and uses the default Redis image.

Step 2: Connect via the Redis Client

With the Redis container running on the correct port, you can now connect to it using the redis-cli command. The correct command to enter into your terminal is:

Breaking Down the Command:

-h 192.168.99.1: Specifies the IP address of your virtual machine (VM) running Docker, allowing the Redis client to know where to connect.

-p 7000: Specifies the port where the Redis server is exposed on the host.

Resolving Firewall or Network Issues

If you are still facing issues after following the above steps, check to ensure that your firewall or network settings are not blocking the connection to the Redis server. You may need to adjust your firewall settings to allow traffic through these ports.

Common Steps Include:

Checking your Windows Firewall settings.

Ensuring any additional security software is configured to allow Docker connections.

Conclusion

By following the outlined solution to correctly start the Redis container and connect via the appropriate ports, you should be able to overcome the connection issues between your Windows Redis client and your Docker server. Troubleshoot any remaining network or firewall issues if necessary, and your setup should work smoothly.
