Exposing Web Apps & Ingress

Berkelium uses the Traefik / NGINX Ingress Controller paired with Cert-Manager to provide automated Let’s Encrypt / Lab SSL certificates for research web services.

Example: Ingress Resource

To expose a Dash, Streamlit, or web application under *.berkelium.lbl.gov:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: synch-viewer-ingress
  namespace: sci-myproject
  annotations:
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
    traefik.ingress.kubernetes.io/router.entrypoints: "websecure"
spec:
  rules:
    - host: viewer-als.berkelium.lbl.gov
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: viewer-service
                port:
                  number: 8080
  tls:
    - hosts:
        - viewer-als.berkelium.lbl.gov
      secretName: viewer-als-tls-cert

Once applied, DNS and TLS certificate provisioning completes in less than 60 seconds.
