Types

type Config 

type Config struct {
	// Annotations are added to the pod spec of the deployed application.  This is
	// useful when using mutating webhook admission controllers to further process
	// pod events.
	Annotations map[string]string `hcl:"annotations,optional"`

	// Context specifies the kube context to use.
	Context string `hcl:"context,optional"`

	// The number of replicas of the service to maintain. If this number is maintained
	// outside waypoint, for instance by a pod autoscaler, do not set this variable.
	Count int32 `hcl:"replicas,optional"`

	// The name of the Kubernetes secret to use to pull the image stored
	// in the registry.
	// TODO This maybe should be required because the vast majority of deployments
	// will be against private images.
	ImageSecret string `hcl:"image_secret,optional"`

	// KubeconfigPath is the path to the kubeconfig file. If this is
	// blank then we default to the home directory.
	KubeconfigPath string `hcl:"kubeconfig,optional"`

	// A map of key vals to label the deployed Pod and Deployment with.
	Labels map[string]string `hcl:"labels,optional"`

	// Namespace is the Kubernetes namespace to target the deployment to.
	Namespace string `hcl:"namespace,optional"`

	// A full resource of options to define ports for your service running on the container
	// Defaults to port 3000.
	Ports []map[string]string `hcl:"ports,optional"`

	// If set, this is the HTTP path to request to test that the application
	// is up and running. Without this, we only test that a connection can be
	// made to the port.
	ProbePath string `hcl:"probe_path,optional"`

	// Optionally define various resources limits for kubernetes pod containers
	// such as memory and cpu.
	Resources map[string]string `hcl:"resources,optional"`

	// A path to a directory that will be created for the service to store
	// temporary data.
	ScratchSpace string `hcl:"scratch_path,optional"`

	// ServiceAccount is the name of the Kubernetes service account to apply to the
	// application deployment. This is useful to apply Kubernetes RBAC to the pod.
	ServiceAccount string `hcl:"service_account,optional"`

	// Port that your service is running on within the actual container.
	// Defaults to DefaultServicePort const.
	// NOTE: Ports and ServicePort cannot both be defined
	ServicePort uint `hcl:"service_port,optional"`

	// Environment variables that are meant to configure the application in a static
	// way. This might be control an image that has mulitple modes of operation,
	// selected via environment variable. Most configuration should use the waypoint
	// config commands.
	StaticEnvVars map[string]string `hcl:"static_environment,optional"`
}
