kubectl -n argocd get applications -o wide
kubectl -n default get deploy,svc,pods -l app.kubernetes.io/name=pulse

Expect Applications kpack and pulse Synced / Healthy, and Pulse pods Running.

If the image rebuilt but pods still use a stale digest (eval uses the mutable :main tag):

kubectl rollout restart deployment/pulse -n default

Open Pulse

LoadBalancer hostname:

kubectl -n default get svc pulse -o jsonpath='{.status.loadBalancer.ingress[0].hostname}{"\n"}'

Open that hostname in a browser (HTTP on port 80), or port-forward:

kubectl -n default port-forward svc/pulse 8080:80

Then open http://localhost:8080 — status cards and the monitors table:
