Functions ¶
func New ¶
func New(ic *plugin.InitContext) (interface{}, error)
New returns a configured runtime
Types ¶
type Config ¶
type Config struct {
// Shim is a path or name of binary implementing the Shim GRPC API
Shim string `toml:"shim"`
// Runtime is a path or name of an OCI runtime used by the shim
Runtime string `toml:"runtime"`
// RuntimeRoot is the path that shall be used by the OCI runtime for its data
RuntimeRoot string `toml:"runtime_root"`
// NoShim calls runc directly from within the pkg
NoShim bool `toml:"no_shim"`
// Debug enable debug on the shim
ShimDebug bool `toml:"shim_debug"`
// ShimNoMountNS prevents the runtime from putting shims into their own mount namespace.
//
// Putting the shim in its own mount namespace ensure that any mounts made
// by it in order to get the task rootfs ready will be undone regardless
// on how the shim dies.
//
// NOTE: This should only be used in kernel older than 3.18 to avoid shims
// from causing a DoS in their parent namespace due to having a copy of
// mounts previously there which would prevent unlink, rename and remove
// operations on those mountpoints.
ShimNoMountNS bool `toml:"shim_no_newns"`
}
Config options for the runtime
