Basic Webapp Chart

This chart creates the necessary resources to deploy a basic, load-balanced web application.

To configure this chart, pass the --set key=value argument to helm install or helm upgrade.

Parameter	Description	Default
letsencrypt.server	The url of the Let's Encrypt server to use	https://acme-staging-v02.api.letsencrypt.org/directory (Set this to https://acme-v02.api.letsencrypt.org/directory for production)
letsencrypt.email	The email address that will receive Let's Encrypt notification emails	[email protected]
postgresql.enabled	Whether or not to install a PostgreSQL instance	false

Dependencies

This chart creates few resources of its own, as the main purpose of this chart is to bootstrap these dependencies onto a cluster:

• cert-manager: Automatically issues and renews TLS certificates
• nginx-ingress: Bootstraps the Nginx Ingress controller, which is used to proxy ingress traffic to services within the cluster
• postgresql: Conditionally installs a PostgreSQL instance

Note: To configure these charts, simply prepend the name of the chart when using the --set argument. For example, to set the defaultBackend.enabled value for the Nginx Ingress controller, use the key nginx-ingress.defaultBackend.enabled.

Google Cloud

When installing on a GKE cluster, a Load Balancer and external IP address will be automatically provisioned for the Nginx Ingress controller. Make sure to switch the IP address from "ephemeral" to "static". This is the IP address to add to your DNS records if you are pointing a domain name to this cluster.
