Using Knative

In this lab, we are going to:

  • Activate Knative
  • Create a Knative service with manifest (using ArgoCD)

Activate Knative​

Go to the Apps section under Platform in the side menu and Drag and Drop Knative from the Disabled apps to the Enabled apps and Deploy Changes

Create a Knative service with manifest (using ArgoCD)​

  1. Open the Gitea app
  2. In Gitea (click Explore in the top menu) you will see a repo created by Otomi for each team, called otomi/team-demo-argocd
  3. Go to the repo and create a new file called hello-ksvc.yaml and copy/paste the following YAML manifest:
apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: hello-ksvc
spec:
  template:
    metadata:
      annotations:
        autoscaling.knative.dev/minScale: '1'
        policy.otomi.io/ignore-sidecar: container-limits,psp-allowed-users
    spec:
      containers:
        - image: harbor.<your-ip>.nip.io/team-demo/hello-world:demo
          securityContext:
            runAsUser: 1001
  1. Open the ArgoCD app
  2. In ArgoCD, click on the team-demo application

You can now see that the Knative service is created.

  1. Optionally you can now expose this service by creating a Service in Otomi.
