The chart also deploys 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 npm based process, which executes 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
