scylla

Scylla

The following is a minimal Cassandra configuration to connect to an external instance.

# apiVersion: astarte.astarte-platform.org/v2alpha1
# ...
spec:
  # ...
  cassandra:
    connection:
      # Replace the connection details with those used by the target instance
      nodes:
        - host: "my-external-cassandra.db.svc.cluster.local"
          port: 9042
      # Create a secret in the cluster and reference it here
      credentialsSecret:
        name: astarte-cassandra-credentials
        usernameKey: username
        passwordKey: password

rabbitmq

RabbitMQ

The following is a minimal RabbitMQ configuration to connect to an external instance.

# apiVersion: astarte.astarte-platform.org/v2alpha1
# ...
spec:
  # ...
  rabbitmq:
    connection:
      # Edit with the connection details in use
      host: "rabbitmq.rabbitmq.svc.cluster.local"
      port: 5672
      # Reference the secret containing login information
      credentialsSecret:
        name: "rabbitmq-connection-secret"
        usernameKey: "username"
        passwordKey: "password"
    managementConnection:
      # Edit with the management connection details in use
      host: "rabbitmq.rabbitmq.svc.cluster.local"
      port: 80

astarte-components

Astarte Components

The following example shows how to merge the api and backend configurations for the housekeeping component into the new, unified structure.

v1alpha3-old

v1alpha3 (Old)

# apiVersion: astarte.astarte-platform.org/v1alpha3
# ...
spec:
  # ...
  components:
    housekeeping:
      api:
        replicas: 1
        disableAuthentication: true
        resources:
          requests:
            cpu: 100m
            memory: 128Mi
          limits:
            cpu: 200m
            memory: 256Mi
      backend:
        replicas: 2
        resources:
          requests:
            cpu: 200m
            memory: 256Mi
          limits:
            cpu: 400m
            memory: 512Mi

v2alpha1-new

v2alpha1 (New)

For the new version, the settings must be combined. Some fields like replicas and resources existed in both old objects, so an appropriate, consolidated set of values must be selected for the new, single service.

# apiVersion: astarte.astarte-platform.org/v2alpha1
# ...
spec:
  # ...
  components:
    housekeeping:
      # Choose the appropriate replica count for the unified service.
      # In this example the backend's replica count is kept.
      replicas: 2
      # The 'disableAuthentication' field from the old 'api' object is moved here.
      disableAuthentication: true
      # Define a single, appropriate set of resources for the unified service.
      resources:
        requests:
          cpu: 200m
          memory: 256Mi
        limits:
          cpu: 400m
          memory: 512Mi
