OneChart generates a KubernetesIngress resource for the Nginx ingress controller with the following settings:

image:
  repository: my-app
  tag: 1.0.0

ingress:
  annotations:
    kubernetes.io/ingress.class: nginx
  host: chart-example.local

Check the Kubernetes manifest:

cat << EOF > values.yaml
image:
  repository: my-app
  tag: 1.0.0

ingress:
  annotations:
    kubernetes.io/ingress.class: nginx
  host: my-app.mycompany.com
EOF

helm template my-app onechart/onechart -f values.yaml

The Nginx ingress controller must be set up in your cluster for this setting to work. For other ingress controllers, please use the matching annotation.

HTTPS

To reference a TLS secret use the tlsEnabled field. The deployment will point to a secret named: tls-$.Release.Name

cat << EOF > values.yaml
image:
  repository: my-app
  tag: 1.0.0

ingress:
  annotations:
    kubernetes.io/ingress.class: nginx
  host: my-app.mycompany.com
  tlsEnabled: true
EOF

helm template my-app onechart/onechart -f values.yaml

HTTPS - Let's Encrypt

If your cluster has Cert Manager running, you should add Cert Manager's annotation to have automated cert provisioning.

# values.yaml
image:
  repository: my-app
  tag: 1.0.0

ingress:
  annotations:
    kubernetes.io/ingress.class: nginx
+   cert-manager.io/cluster-issuer: letsencrypt
  host: my-app.mycompany.com
  tlsEnabled: true

Listening on multiple domains

cat << EOF > values.yaml
image:
  repository: my-app
  tag: 1.0.0

ingresses:
  - host: one.mycompany.com
    annotations:
      kubernetes.io/ingress.class: nginx
    tlsEnabled: true
  - host: two.mycompany.com
    annotations:
      kubernetes.io/ingress.class: nginx
    tlsEnabled: true
EOF

helm template my-app onechart/onechart -f values.yaml
