Functions

func AgentWithConfig

func AgentWithConfig(ctx context.Context, agentNamespace, controllerNamespace, agentScope string, cg *client.Getter, output io.Writer, tokenName string, opts *Options) error

AgentWithConfig writes the agent manifest to the given writer. It includes an updated agent token secret from the cluster. It finds or creates the agent config inside a configmap.

This is used when importing a cluster.

func GetCAFromConfig

func GetCAFromConfig(rawConfig clientcmdapi.Config) ([]byte, error)

func GetHostFromConfig

func GetHostFromConfig(rawConfig clientcmdapi.Config) (string, error)

func Manifest

func Manifest(namespace string, agentScope string, opts ManifestOptions) []runtime.Object

Manifest builds and returns a deployment manifest for the fleet-agent with a cluster role, two service accounts and a network policy

This is called by both, import and manageagent.
