func FuseoverlayfsSupported

func FuseoverlayfsSupported(root string) error

func OverlaySupported

func OverlaySupported(root string) error

func PreloadImages

func PreloadImages(ctx context.Context, cfg *config.Node) error

PreloadImages reads the contents of the agent images directory, and attempts to import into containerd any files found there. Supported compressed types are decompressed, and any .txt files are processed as a list of images that should be pre-pulled from remote registries. If configured, imported images are retagged as being pulled from additional registries.

func Run

func Run(ctx context.Context, cfg *config.Node) error

Run configures and starts containerd as a child process. Once it is up, images are preloaded or pulled from files found in the agent images directory.

func SetupContainerdConfig

func SetupContainerdConfig(cfg *config.Node) error

SetupContainerdConfig generates the containerd.toml, using a template combined with various runtime configurations and registry mirror settings provided by the administrator.
