Error: Docker memcached connection refused

When connecting to a Memcached server operating within a Docker container, the error “Docker Memcached connection rejected” commonly occurs. Memcached is a popular in-memory caching solution that caches data in memory to increase web application speed.

Docker, on the other hand, is a platform that enables developers to package their apps and dependencies into a container that can operate across several platforms.

When attempting to connect to a Memcached server operating within a Docker container, the user may receive a “connection rejected” error. This error indicates that the client was unable to connect to the Memcached server because it was rejected.

Error: Docker memcached connection refused: Causes

This error might arise for a variety of reasons, including:

1. Inadequate configuration. If the Memcached server is not correctly configured, it may be unable to accept connections from clients outside the container.

   Check that the server is listening on the proper port and that the firewall rules permit inbound connections.
2. Docker containers have their own networking stack. This might pose problems when attempting to connect to a service operating within a container.

   Check that the container is operating and that it can be reached from the host system.
3. DNS issues. If the Memcached server is operating within a container and the client is running on the host system, DNS problems may prevent the client from determining the container’s hostname.

   Instead, use the IP address of the container.

To address the “Docker Memcached connection rejected” problem, the user should double-check the setup of both the Memcached server and the Docker container.

Also, the user should examine the logs of the Memcached server and the Docker container for any errors or warnings that may give additional insight into the problem.
