Lab Prerequisites

Prerequisites

1. Make sure App Platform is installed with DNS. See here. Not needed when using the LKE automatic installation.

2. Sign in with a user that has the platform-administrator role

3. Enable Prometheus on the platform level.

4. Enable additional Apps on the platform level to support the following labs:

Lab	App

Trigger builds	Harbor
Manually Push images to Harbor	Harbor
Scan running containers for vulnerabilities	Prometheus, Grafana, Trivy Operator
View container logs	Loki, Grafana
Tracing with Open Telemetry	Loki, Otel, Tempo
Create a RabbitMQ cluster	RabbitMQ

info

For the Tracing with Open Telemetry Lab, tracing needs to be configured in the Istio and Nginx Ingress apps.

5. Create a Team called labs with Dashboards and Alerts enabled. See here how to create Teams.

6. Create a user and make this user a member of the labs Team. In the labs we'll be using the user labs-user@labs.com. See here how to create users and assign them to Teams.

info

The App Platform will automatically create an organization for each Team in Gitea. Only members of the Team are added to the Owners group of this organization. It is possible to go through the labs using the (default) platform-admin user account that was created during the installation of the App Platform. When using the platform-admin user, then make sure to add your account to the Owners group of the Team's organization in Gitea. Follow the instruction for adding the platform-admin user to the Owners group of a Team's organization in Gitea here

6. Add the Kube API to the Cluster Settings. Select the platform view and click on Settings in the left menu. Then click on Cluster. When using LKE: You can find the Kube API URL in the Summary of your LKE cluster. Here it is called the Kubernetes API Endpoint. You can remove :443 at the end.
