func Register Uses

func Register(plugins *admission.Plugins)

Register registers a plugin

func TokenVolumeSource Uses

func TokenVolumeSource() *api.ProjectedVolumeSource

type Plugin Uses

type Plugin struct {

    // LimitSecretReferences rejects pods that reference secrets their service accounts do not reference
    LimitSecretReferences bool
    // RequireAPIToken determines whether pod creation attempts are rejected if no API token exists for the pod's service account
    RequireAPIToken bool
    // MountServiceAccountToken creates Volume and VolumeMounts for the first referenced ServiceAccountToken for the pod's service account
    MountServiceAccountToken bool
    // contains filtered or unexported fields

Plugin contains the client used by the admission controller

func NewServiceAccount Uses

func NewServiceAccount() *Plugin

NewServiceAccount returns an admission.Interface implementation which limits admission of Pod CREATE requests based on the pod's ServiceAccount: 1. If the pod does not specify a ServiceAccount, it sets the pod's ServiceAccount to "default" 2. It ensures the ServiceAccount referenced by the pod exists 3. If LimitSecretReferences is true, it rejects the pod if the pod references Secret objects which the pod's ServiceAccount does not reference 4. If the pod does not contain any ImagePullSecrets, the ImagePullSecrets of the service account are added. 5. If MountServiceAccountToken is true, it adds a VolumeMount with the pod's ServiceAccount's api token secret to containers
