Set up memcached with a metric exporter on Amazon EKS and Kubernetes

memcached is an open-source memory object caching system. For more information, see What is Memcached?.

If you are running memcached on a cluster with the Fargate launch type, you need to set up a Fargate profile before doing the steps in this procedure. To set up the profile, enter the following command. Replace MyCluster with the name of your cluster.

eksctl create fargateprofile --cluster MyCluster \
--namespace memcached-sample --name memcached-sample
