memcached-advanced

Memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load. The Memcached Advanced Helm chart automates deployment and configuration of Memcached in Kubernetes clusters using Minimus images with hardened security and production-grade configuration.

Prerequisites

A subscription to the Minimus images included in the chart
A running Kubernetes cluster (v1.21 or higher is recommended)
kubectl installed and configured
Helm v3.8 or higher for OCI support (Installation instructions)
Cluster Admin privileges

Try It Out

In this example we will deploy Memcached on a Kubernetes cluster using the Minimus Memcached Advanced Helm chart. Memcached will be configured as a high-performance in-memory cache out of the box.

Step 1: Start Cluster

If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions

Step 2: Create Namespace

Create a namespace:

kubectl create ns memcached-advanced

Step 3: Deploy the Helm Chart

Deploy the Minimus Helm chart:

helm install my-memcached-advanced oci://helm.mini.dev/memcached-advanced \
  --version 8.6.2 \
  -n memcached-advanced \
  --wait

If you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using -f values.yaml:

helm install my-memcached-advanced oci://helm.mini.dev/memcached-advanced \
  --version 8.6.2 \
  -f values.yaml \
  -n memcached-advanced \
  --wait

Step 4: Verify Memcached Advanced is Running

Check that the Memcached pods are running:

kubectl get pods -n memcached-advanced -l app.kubernetes.io/name=memcached

You should see output similar to:

NAME                          READY   STATUS    RESTARTS   AGE
my-memcached-advanced-0       1/1     Running   0          2m

Step 5: Test Memcached Connection

Forward the Memcached port to your local machine:

kubectl port-forward svc/my-memcached-advanced 11211:11211 -n memcached-advanced

In another terminal, test SET and GET operations:

printf "set testkey 0 0 5\r\nhello\r\n" | nc -w 2 localhost 11211

You should see:

STORED

Retrieve the value:

printf "get testkey\r\n" | nc -w 2 localhost 11211

You should see:

VALUE testkey 0 5
hello
END

Step 6: Clean Up

Uninstall the chart and delete the namespace to remove all resources:

helm uninstall my-memcached-advanced -n memcached-advanced
kubectl delete namespace memcached-advanced
