Setup Memcached
Locally
You can run Memcached locally using Docker:
docker run --name my-memcache -d memcached
You can then interact with the server using localhost:11211
.
Kubernetes
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:
memcached.default.svc.cluster.local:11211
Create a Dapr component
The next step is to create a Dapr component for Memcached.
Create the following YAML file named memcached.yaml
:
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
name: <NAME>
namespace: <NAMESPACE>
spec:
type: state.memcached
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"
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here
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
.
