Component format

To setup Memcached state store create a component of type state.memcached. See [this guide]({{< ref "howto-get-save-state.md#step-1-setup-a-state-store" >}}) 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: "1000"

{{% alert title="Warning" color="warning" %}} The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}). {{% /alert %}}

Spec metadata fields

Field	Required	Details	Example
hosts	Y	Comma delimited endpoints	"memcached.default.svc.cluster.local:11211"
maxIdleConnections	N	The max number of idle connections. Defaults to "2"	"3"
timeout	N	The timeout for the calls in milliseconds. Defaults to "1000"	"1000"

Setup Memcached

{{< tabs "Self-Hosted" "Kubernetes" >}}

{{% codetab %}} You can run Memcached locally using Docker:

docker run --name my-memcache -d memcached

You can then interact with the server using localhost:11211. {{% /codetab %}}

{{% codetab %}} 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 {{% /codetab %}}

{{< /tabs >}}
