PodTemplateSpec

The Kubernetes PodTemplateSpec defines how pods should run. You can customize everything you need to in your deployment using this resource.

For more information see the PodTemplateSpec documentation.

A PodTemplateSpec can be provided on both GatewayConfiguration and DataPlane resources.

When using the GatewayConfiguration resource, the ControlPlane and DataPlane resources are configured independently.

• ControlPlane pods take their configuration from the spec.controlPlaneOptions.deployment.podTemplateSpec field.
• DataPlane pods take their configuration from the spec.dataPlaneOptions.deployment.podTemplateSpec field.

When using the DataPlane resource directly, you specify spec.deployment.podTemplateSpec.

Here are some examples for the most common use of PodTemplateSpec:

• Customize the DataPlane image
• Deploy a sidecar container

In addition, you can also customize:

• Volume mounts
• Node affinity / anti-affinity
• Service account used to run the Pod

If you need additional information about customizing your deployment, raise an issue in Kong/gateway-operator.
