The error message 'docker memcached not working' can be caused by a variety of factors. Firstly, if the Docker image doesn't have the Memcached package installed or if the container isn't set up with proper configurations for Memcached, then this error can occur. Secondly, if there is an issue with the network configuration or if the port used by Memcached is unavailable, then the container will fail to start, and the error message will appear.
Another possible cause of this error is a conflict with other applications running on the same host. For instance, if another service is already using the port specified for Memcached, it won't work, and you'll see this error message. Similarly, if the system's resources are constrained, such as insufficient memory, CPU, or disk space, Memcached may not be able to start, leading to the error.
To resolve the 'docker memcached not working' error, start by checking your Dockerfile or docker-compose.yml file to ensure there aren't any issues with the container's configuration. Make sure that the Memcached package is correctly installed and that the container's network configuration is set up correctly. You can also try to use a different port to see if the problem persists.
If the configuration looks fine, check if the port specified for Memcached is already in use by another service. You can do this by running the
netstat command and looking for any conflicts. If the port is occupied, you may need to stop the service using it, or assign a different port number for Memcached.
Lastly, if the above steps don't work, consider increasing the system's resources available to your container, such as RAM or disk space. Additionally, you can try updating your Memcached version or checking the system logs for more information about what's causing the error.
