Install Service Catalog

The Open Service Broker API provides a standard RESTful interface for provisioning services from a provided catalog, such as Astra DB databases.

The Astra DB Service Broker supports only Kubernetes v1.13 and later.

Prerequisites

Running Kubernetes cluster you can access via command line
Helm package manager for Kubernetes
Service Catalog command-line interface
DataStax Astra DB account with service account credentials

Procedure

For each Kubernetes cluster, install the service catalog:

helm repo add service-catalog https://kubernetes-sigs.github.io/service-catalog
helm repo update
helm install catalog service-catalog/catalog --namespace catalog --create-namespace

Create a Kubernetes secret with the service account information from Astra DB:

kubectl create secret generic astra-creds \
 --from-literal=username=unused \
 --from-literal=password=`echo '<creds>'| base64 -w 0

Replace the <service_account_credentials> with the snippet of JSON from your Astra DB service account. For example:

{
  "clientId":"<clientId>",
  "clientName":"<clientName>",
  "clientSecret":"<clientSecret>"
}

svcat register astra \
  --url https://broker.astra.datastax.com/ \
  --basic-secret astra-creds

The Service Catalog automatically queries for available services on Astra DB and displays the available plan options:

svcat marketplace

returns:

NAME    NAMESPACE       CLASS                   DESCRIPTION
+-----------+-----------+----------------+------------------------------------+
A10       default     astra-database   6 vCPU, 24GB DRAM, 20GB
                                    Storage
A20       default     astra-database   12 vCPU, 48GB DRAM, 40GB
                                    Storage
...

This result shows only a portion of the available Astra DB tiers from the Service Catalog.
