Helm Chart Configuration Reference

You can use the Palette Helm Chart to install Palette in a multi-node Kubernetes cluster in your production environment. The Helm chart allows you to customize values in the values.yaml file. This reference lists and describes parameters available in the values.yaml file from the Helm Chart for your installation. To learn how to install Palette using the Helm Chart, refer to the Palette Helm install guide.

Required Parameters

The following parameters are required for a successful installation of Palette.

Parameters	Description	Type
config.env.rootDomain	Used to configure the domain for the Palette installation. We recommend you create a CNAME DNS record that supports multiple subdomains. You can achieve this using a wild card prefix, *.palette.abc.com. Review the Environment parameters to learn more.	String

Speak with your support representative before enabling this option.

Parameters	Description	Type	Default value
nats.enabled	Specifies whether to enable the deployment of a NATS load balancer.	Boolean	true
nats.internal	Specifies whether to deploy a load balancer or use the host network. If this value is set to true, then the remaining NATS parameters are ignored.	Boolean	true
nats.natsUrl	The NATS URL. This can be a comma separated list of <dns_name:port> mappings for the NATS load balancer service. For example, "message1.dev.spectrocloud.com:4222,message2.dev.spectrocloud.com:4222". This parameter is mandatory if nats.internal is set to false. If nats.internal is set to true, you can leave this parameter empty.	String	""

gRPC

gRPC is used for communication between Palette components. You can enable the deployment of an additional load balancer for gRPC.

Speak with your support representative before enabling this option. Dual support for NATS and gRPC is available.

If you want to use an external gRPC endpoint, you must provide a domain name for the gRPC endpoint and a valid x509 certificate. Additionally, you must provide a custom domain name for the endpoint. A CNAME DNS record must point to the IP address of the gRPC load balancer. For example, if your Palette domain name is palette.example.com, you could create a CNAME DNS record for grpc.palette.example.com that points to the IP address of the load balancer dedicated to gRPC.
