Couchbase

Detailed information on the Couchbase state store component

Create a Couchbase state store

• Self-Hosted
• Kubernetes

You can run Couchbase locally using Docker:

docker run -d --name db -p 8091-8094:8091-8094 -p 11210:11210 couchbase

You can then interact with the server using localhost:8091 and start the server setup.

The easiest way to install Couchbase on Kubernetes is by using the Helm chart:

helm repo add couchbase https://couchbase-partners.github.io/helm-charts/
helm install couchbase/couchbase-operator
helm install couchbase/couchbase-cluster

Create a Dapr component

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

Create the following YAML file named couchbase.yaml:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: state.couchbase
  version: v1
  metadata:
  - name: couchbaseURL
    value: <REPLACE-WITH-URL> # Required. Example: "http://localhost:8091"
  - name: username
    value: <REPLACE-WITH-USERNAME> # Required.
  - name: password
    value: <REPLACE-WITH-PASSWORD> # Required.
  - name: bucketName
    value: <REPLACE-WITH-BUCKET> # Required.

Warning

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 Couchbase state store to Kubernetes, use the kubectl CLI:

kubectl apply -f couchbase.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.
