Detailed information on the Memcached state store component

Setup a Memcached state store

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 will install 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:


Create a Dapr component

The next step is to create a Dapr component for Memcached.

Create the following YAML file named memcached.yaml:

kind: Component
  name: <NAME>
  namespace: <NAMESPACE>
  type: state.memcached
  version: v1
  - 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"

Apply the configuration

In Kubernetes

To apply the Memcached state store to Kubernetes, use the kubectl CLI:

kubectl apply -f memcached.yaml

Running locally

To run locally, create a components dir containing the YAML file and provide the path to the dapr run command with the flag --components-path.
