memcached-operator provides a single Service endpoint that memcached client applications can connect to to make use of the memcached cluster. It provides this via a memcached proxy which is automatically updated whenever memcached instances are added or removed from the cluster.
memcached-operator supports sharded and replicated pools of servers as well as combinations of both strategies.
See the documentation for more information.
Project status: alpha
memcached-operator is still under active development and has not been extensively tested yet. Use at your own risk. Backward-compatibility is not supported for alpha releases.
memcached-operator relies on subresources for CRDs which is in 1.10+
You can install the memcached-operator using the included helm chart. Check out the git repository and run this in the root directory.
$ helm install --name memcached-operator charts/memcached-operator
The easiest way to create a memcached cluster is using the memcached helm chart:
$ helm install --name sharded stable/memcached
You can then create a memcached proxy to connect to the cluster.
apiVersion: ianlewis.org/v1alpha1 kind: MemcachedProxy metadata: name: sharded-example spec: rules: type: "sharded" service: name: "sharded-memcached" port: 11211
$ kubectl apply -f docs/sharded-example.yaml
You can then access your memcached cluster via the
sharded-memcachedservice. Check the documentation for more information.
You can remove the memcached-operator by deleting the helm release.
$ helm delete --purge memcached-operator
