Memcached
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.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. Defaults to "1000ms" |
"1000ms" |
Setup Memcached
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
