Functions

func LoadPodManifest

func LoadPodManifest(root string) (*schema.PodManifest, error)

LoadPodManifest loads a Pod Manifest.

Types

type Pod

type Pod struct {
	RuntimePod        // embedded runtime parameters
	Root       string // root directory where the pod will be located
	UUID       types.UUID
	Manifest   *schema.PodManifest
	Images     map[string]*schema.ImageManifest
	UidRange   user.UidRange
}

Pod encapsulates a PodManifest and ImageManifests

func LoadPod

func LoadPod(root string, uuid *types.UUID, rp *RuntimePod) (*Pod, error)

LoadPod loads a Pod Manifest (as prepared by stage0), the runtime data, and its associated Application Manifests, under $root/stage1/opt/stage1/$apphash

func (*Pod) AppNameToImageName

func (p *Pod) AppNameToImageName(appName types.ACName) types.ACIdentifier

AppNameToImageName takes the name of an app in the Pod and returns the name of the app's image. The mapping between these two is populated when a Pod is loaded (using LoadPod).

func (*Pod) SaveRuntime

func (p *Pod) SaveRuntime() error

SaveRuntime persists just the runtime state. This should be called when the pod is started.

type RuntimePod

type RuntimePod struct {
	MetadataServiceURL string         `json:"MetadataServiceURL"`
	PrivateUsers       string         `json:"PrivateUsers"`
	MDSToken           string         `json:"MDSToken"`
	Hostname           string         `json:"Hostname"`
	Debug              bool           `json:"Debug"`
	Mutable            bool           `json:"Mutable"`
	ResolvConfMode     string         `json:"ResolvConfMode"`
	EtcHostsMode       string         `json:"EtcHostsMode"`
	NetList            common.NetList `json:"NetList"`
	Interactive        bool           `json:"Interactive"`
	InsecureOptions    struct {
		DisablePaths        bool `json:"DisablePaths"`
		DisableCapabilities bool `json:"DisableCapabilities"`
		DisableSeccomp      bool `json:"DisableSeccomp"`
	} `json:"InsecureOptions"`
	IPCMode string `json:"IPCMode"`
}

RuntimePod stores internal state we'd like access to. There is no interface, and noone outside the stage1 should access it. If you find yourself needing one of these members outside of the stage1, then it should be set as an annotation on the pod. This includes things like insecure options and the mds token - they are provided during init but needed for `app add`.
