H2O Wave

This chart deploys and executes a stateful set of H2O-Wave gateway servers using dedicated docker image.

The chart also deploys a headless service and a load balancer service enabling external access.

Containers

Init Container

Chart contains an initialization container for any extra steps.

Main Container

Main container of this chart is an executable based process, which runs actual service and typically has liveness probes enabled.

Configuration

Local Configuration

Chart contains:

• 1 x config map containing build/execution files mounted on /app/config

• 1 x environment config map that can be used to add environment variables

• 1 x secret that can be used to add secret files mounted on /app/secrets

• 1 x environment secret that can be used to add environment variables

Global Configuration

Chart containers also have access to:

• global-config: Mounted on /app/globalconfig including key-value pairs and extra lines to include in application.properties files

• global-config-env: A config map that can be used to add environment variables for all namespace deployments

• global-secrets: Mounted on /app/globalsecrets including key-secret pairs and extra lines to include in application.properties files

• global-secrets-env: A secret that can be used to add environment variables for all namespace deployments

• global-secrets-docker: Used as the imagePullSecrets secret
