Memcached

Detailed information on the Memcached state store component

Component format

To setup Memcached state store create a component of type state.memcached. See this guide on how to create and apply a state store configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
spec:
  type: state.memcached
  version: v1
  metadata:
  - name: hosts
    value: <REPLACE-WITH-COMMA-DELIMITED-ENDPOINTS> # Required. Example: "memcached.default.svc.cluster.local:11211"
  - name: maxIdleConnections
    value: <REPLACE-WITH-MAX-IDLE-CONNECTIONS> # Optional. default: "2"
  - name: timeout
    value: <REPLACE-WITH-TIMEOUT> # Optional. default: "1000ms"

Warning

The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.

Setup Memcached

• Self-Hosted
• Kubernetes

You can run Memcached locally using Docker:

docker run --name my-memcache -d memcached

You can then interact with the server using localhost:11211.

The easiest way to install Memcached on Kubernetes is by using the Helm chart:

helm install memcached stable/memcached

This installs Memcached into the default namespace. To interact with Memcached, find the service with: kubectl get svc memcached.

For example, if installing using the example above, the Memcached host address would be:

memcached.default.svc.cluster.local:11211
