Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

func NewClient 

func NewClient(ctx context.Context, cfg *Configuration) (c *Client, err error)

func (*Client) AddCompletedLayers 

func (c *Client) AddCompletedLayers(compressedLayerDigest string)

func (*Client) Close 

func (c *Client) Close()

func (*Client) FindBaseImage 

func (c *Client) FindBaseImage(ctr *containerd.Client, base, ref string) (img containerd.Image, err error)

FindBaseImage find the closest available image for the requested image, if user appointed an image, then this function will be used for confirming the appointed image is available in the local storage

func (*Client) GetFilesystemPath 

func (c *Client) GetFilesystemPath(cd string) string

func (*Client) GetFilesystemRoot 

func (c *Client) GetFilesystemRoot() string

func (*Client) GetMountingPoint 

func (c *Client) GetMountingPoint(ssId string) string

func (*Client) InitCLIServer 

func (c *Client) InitCLIServer() (err error)

-----------------------------------------------------------------------------

func (*Client) InitSnapshotter 

func (c *Client) InitSnapshotter() (err error)

InitSnapshotter initializes the snapshotter service

func (*Client) LoadImage 

func (c *Client) LoadImage(ctr *containerd.Client, manifest digest.Digest) (manager *Manager, err error)

LoadImage loads image manifest from content store to the memory, if it is in memory, return manager directly.

This method should not use any snapshotter methods to avoid recursive lock. This method is similar to PullImage, but it only uses content store.

func (*Client) Mount 

func (c *Client) Mount(ld digest.Digest, ssId string, sn *snapshots.Info) (mnt string, err error)

Mount returns the mountpoint for the given snapshot - md: manifest digest - ld: uncompressed layer digest - ssId: snapshot id

func (*Client) Notify added in v0.2.1 

func (c *Client) Notify(proxyCfg string, reference name.Reference, insecure bool) error

func (*Client) Ping added in v0.2.1 

func (c *Client) Ping(proxyCfg string) (int64, string, string, error)

func (*Client) PrepareManager added in v0.2.1 

func (c *Client) PrepareManager(namespace string, manifest digest.Digest) error

func (*Client) PullImage 

func (c *Client) PullImage(
	ctr *containerd.Client, base containerd.Image,
	ref, platform, proxyCfg string, ready *chan PullFinishedMessage,
)

PullImage pulls an image from a registry and stores it in the content store it also stores the manager in memory. In case there exists another manager in memory, it removes it and re-pull the image

func (*Client) ScanExistingFilesystems added in v0.2.3 

func (c *Client) ScanExistingFilesystems()

----------------------------------------------------------------------------- ScanExistingFilesystems scans place where the extracted file content is stored in case the file system has not extracted fully (without the `complete.json` file), we will remove the directory.

func (*Client) StartCLIServer 

func (c *Client) StartCLIServer()

func (*Client) StartSnapshotter 

func (c *Client) StartSnapshotter()

StartSnapshotter starts the snapshotter service, should be run in a goroutine

func (*Client) Unmount 

func (c *Client) Unmount(cd, sn string) error

func (*Client) UploadTraces 

func (c *Client) UploadTraces(proxyCfg string, tc *fs.TraceCollection) error

type Configuration 

type Configuration struct {
	LogLevel string `json:"log_level"`
	ClientId string `json:"id"`

	// path to database
	Metadata string `json:"metadata"`

	// socket address
	Socket     string `json:"socket"`
	DaemonType string `json:"daemon_type"`
	Daemon     string `json:"daemon"`
	Containerd string `json:"containerd"`
	Namespace  string `json:"default_namespace"`
	TracesDir  string `json:"traces_dir"`

	// registry + proxy
	DefaultProxy   string `json:"default_proxy"`
	FileSystemRoot string `json:"fs_root"`

	Proxies map[string]*ProxyConfig `json:"configs"`
}

func LoadConfig 

func LoadConfig(cfgPath string) (c *Configuration, p string, n bool, error error)

func NewConfig 

func NewConfig() *Configuration

func (*Configuration) SaveConfig 

func (c *Configuration) SaveConfig() error

type Manager 

type Manager struct {
	receive.DeltaBundle
	// contains filtered or unexported fields
}

Manager should be unmarshalled from a json file and then Populate() should be called to populate other fields

func (*Manager) CreateSnapshots 

func (m *Manager) CreateSnapshots(c *Client) (chainIds []digest.Digest, err error)

CreateSnapshots for chainIds should unlock the managerMapLock before calling CreateSnapshot

func (*Manager) Extract 

func (m *Manager) Extract(r *io.ReadCloser) (err error)

func (*Manager) GetPathBySerial added in v0.2.1 

func (m *Manager) GetPathBySerial(serial int64) string

func (*Manager) GetPathByStack added in v0.2.1 

func (m *Manager) GetPathByStack(stack int64) string

func (*Manager) Init 

func (m *Manager) Init(ctr *containerd.Client, client *Client, ctx context.Context, cfg *Configuration, ready bool,
	manifest *v1.Manifest, imageConfig *v1.Image, manifestDigest digest.Digest)

Init populates the manager with the necessary information and data structures. Use json.Unmarshal to unmarshal the json file from data storage into a Manager struct.

  • ready: if set to false, we will then use Extract() to get the content of the file
  • cfg: configuration of the client
  • image, manifest, imageConfig: information about the image (maybe we don't need this)

do not change any outside state, only the manager itself
