Types

type Config

type Config struct {

	// InitContainers - inject one or more initContainers into the pod spec.
	InitContainers []corev1.Container

	// Containers - inject one or more containers into the pod spec.
	Containers []corev1.Container

	// ExistingContainerConfig - configuration for injecting into the pre-existing containers.
	ExistingContainerConfig
}

Config is the struct used to parse injection config items for Simple Sidecar. The InitContainers, Containers, Volumes, and EnvVars fields are arrays of Kubernetes objects that will be added to the pod spec.

type ExistingContainerConfig

type ExistingContainerConfig struct {
	// Volumes - inject one or more volumes into pre-existing pod specs.
	Volumes []corev1.Volume

	// EnvVars - inject one or more environment variables into pre-existing pod specs.
	EnvVars []corev1.EnvVar

	// VolumeMounts - inject one or more volume mounts into pre-existing pod specs.
	// BEFORE sidecar injection.
	VolumeMounts []corev1.VolumeMount
}

ExistingContainerConfig provides configuration for injecting into the pre-existing containers. This is useful for utilizing the functionality of injected containers

type MultiConfig

type MultiConfig map[string]Config

MultiConfig is a map of Config objects. This allows for multiple named configurations to be loaded from a single configuration file. The name of the configuration is the key, it is used to determine which configuration to use when injecting sidecars.

func LoadConfig

func LoadConfig(configFile string) (cfg MultiConfig, err error)

LoadConfig loads the configuration from the specified file and returns a MultiConfig object.

func NewWebhookServer

func NewWebhookServer(cfg *WebhookServerConfig) *WebhookServer

NewWebhookServer creates a new WebhookServer object with the specified configuration.

func (*WebhookServer) Serve

func (whs *WebhookServer) Serve(w http.ResponseWriter, r *http.Request)

func (*WebhookServer) Start

func (whs *WebhookServer) Start() error

func (*WebhookServer) Stop

func (whs *WebhookServer) Stop()

type WebhookServerConfig

type WebhookServerConfig struct {
	Port           int
	CertPEM        string
	KeyPEM         string
	SidecarConfigs MultiConfig
	InfoLogger     *log.Logger
	ErrorLogger    *log.Logger
	WarnLogger     *log.Logger
}
