Couchbase

Detailed information on the Couchbase state store component

Component format

To setup Couchbase state store create a component of type state.couchbase. 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.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.

Spec metadata fields

Field	Required	Details	Example
couchbaseURL	Y	The URL of the Couchbase server	`"http://localhost:8091"`
username	Y	The username for the database	`"user"`
password	Y	The password for access	`"password"`
bucketName	Y	The bucket name to write to	`"bucket"`

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
