Ambassador Edge Stack quick start

1. Installation

We'll start by installing Ambassador Edge Stack into your cluster.

We recommend using Helm but there are other options below to choose from.

2. Routing traffic from the edge

Like any other Kubernetes object, Custom Resource Definitions (CRDs) are used to declaratively define Ambassador Edge Stack’s desired state. The workflow you are going to build uses a simple demo app and the Mapping CRD, which is the core resource that you will use with Ambassador Edge Stack. It lets you route requests by host and URL path from the edge of your cluster to Kubernetes services.

1. First, apply the YAML for the “Quote of the Moment" service.

   The Service and Deployment are created in your default namespace. You can use kubectl get services,deployments quote to see their status.

2. Copy the configuration below and save it to a file called quote-backend.yaml so that you can create a Mapping on your cluster. This Mapping tells Ambassador Edge Stack to route all traffic inbound to the /backend/ path to the quote Service.

3. Apply the configuration to the cluster:

   With our Mapping created, now we need to access it!

4. Store the Ambassador Edge Stack load balancer IP address to a local environment variable. You will use this variable to test accessing your service.

5. Test the configuration by accessing the service through the Ambassador Edge Stack load balancer:

   curl -Lk https://$AMBASSADOR_LB_ENDPOINT/backend/

3. Connect your cluster to Ambassador Cloud

The Service Catalog is a web-based interface that lists all of your cluster's Services. You can view, add, and update metadata associated with each Service, such as the owner, version control repository, and associated Slack channel.

1. Log in to Ambassador Cloud with your preferred identity provider.

2. At the top, click Add Services then click Connection Instructions in the Edge Stack installation section.

3. Follow the prompts to name the cluster and click Generate a Cloud Token.

4. Follow the prompts to install the cloud token into your cluster.

5. When the token installation completes, refresh the Service Catalog page.
