Install the Kong Mesh Example Application

To install Styra on Kong Mesh, copy and paste the installation commands from Systems > Settings > Install from your Kong Mesh System into your terminal. You can install Kong Mesh with or without SLP. If you install Kong Mesh with SLP, a new AuthService points to the OPA patches OPA sidecar container along with its configuration to connect to Styra DAS through Styra Local Plane (SLP).

The Styra Local Plane provides detailed information on SLP.

The Kong Mesh Quick Start provides the link to install the sample application. It consists of the following components that should now run in your minikube. All resources are suffixed by the SYSTEM ID to mark them as unique.

  • example-app: A simple HTTP web server that allows employees of a hypothetical organization to obtain salary details at the path /finance/salary. It also exposes a path /hr/dashboard that is only accessible by employees who are part of HR. Functionally, it is a simple echo server that returns a HTTP 200 response with a plain or text body which contains a success or error message.

  • client-load: A simple shell script that generates pre-configured HTTP GET requests to simulate the API request being made to the edge-stack and to test the behavior of the deployed policy. It generates data to visualize the impact of the configured ingress and egress policies.

  • slp (optional): The Styra Local Plane (SLP) is a service that acts as an intermediary between the OPAs and Styra DAS. OPAs are configured to retrieve bundles from SLP rather than directly from Styra DAS. This increases availability as SLP fetches bundles from Styra DAS and persists them to disk. Policies are still available to new or restarted OPAs even if Styra DAS is unavailable.

  • Each application has a Kong Mesh proxy and OPA as sidecar container.

When you run the Kong Mesh example application, the OPA sidecars access the policy from the Styra DAS tenant and start enforcing it. This process takes few minutes to complete.
