(v3.0.0-rc7) Argo-server deployment readiness prob httpGet uses http scheme instead of https

[farrajota]

Summary

When testing the new v3.0.0-rc7 version, the argo-server deployment pod initialization does not complete. The pod's readiness prob times out because it is fetching from the HTTP scheme instead of HTTPS.

Fix: Edit the argo server deployment

$ kubectl -n argo edit deployments.apps argo-server

...
    spec:
      containers:
      - args:
        - server
        image: argoproj/argocli:v3.0.0-rc7
        imagePullPolicy: IfNotPresent
        name: argo-server
        ports:
        - containerPort: 2746
          name: web
          protocol: TCP
        readinessProbe:
          failureThreshold: 3
          httpGet:
            path: /
            port: 2746
            scheme: HTTPS  # <- Change this from HTTP
