We'll start by installing Ambassador Edge Stack into your cluster.
We recommend using Helm but there are other options below to choose from.
Now is a great time to enhance your Ambassador Edge Stack experience and take advantage of Ambassador Cloud's advanced capabilities.
Log in to Ambassador Cloud with GitHub, GitLab or Google and select your team account.
At the top, click Add Services then click Connection Instructions in the "Connect your installation" section.
Follow the prompts to name the cluster and click Generate a Cloud Token.
Follow the prompts to install the cloud token into your cluster.
When the token installation is completed, your services are listed in Ambassador Cloud.
Ambassador Edge Stack uses Kubernetes Custom Resource Definitions (CRDs) to declaratively define its desired state. The workflow you are going to build uses a simple demo app, a
Listener CRD, and a
Mapping CRD. The
Listener CRD tells Ambassador Edge Stack what port to listen on, and the
Mapping CRD tells Ambassador Edge Stack how to route incoming requests by host and URL path from the edge of your cluster to Kubernetes services.
Start by creating a
Listenerresource for HTTP on port 8080:
Apply the YAML for the "Quote" service.
Generate the YAML for a
Mappingto tell Ambassador Edge Stack to route all traffic inbound to the

In this step, we'll be using the Mapping Editor, which you can find in the service details view of your Ambassador Cloud connected installation. Open your browser to https://app.getambassador.io/cloud/services/quote/details and click on New Mapping.
Default options are automatically populated. Enable and configure the following settings, then click Generate Mapping:
Whether you decide to automatically push the change to Git for this newly create Mapping resource or not, the resulting Mapping should be similar to the example below.
Apply this YAML to your target cluster now.
Store the Ambassador Edge Stack load balancer IP address to a local environment variable. You will use this variable to test access to your service.
Test the configuration by accessing the service through the Ambassador Edge Stack load balancer:
