func CreateContainer ¶

func CreateContainer(ctx context.Context, sandbox vc.VCSandbox, ociSpec specs.Spec, rootFs vc.RootFs, containerID, bundlePath string, disableOutput bool, disableGuestEmptyDir bool) (vc.Process, error)

CreateContainer create a container

func CreateRuntimeHooks ¶

func CreateRuntimeHooks(ctx context.Context, spec specs.Spec, cid, bundlePath string) error

func CreateSandbox ¶

func CreateSandbox(ctx context.Context, vci vc.VC, ociSpec specs.Spec, runtimeConfig oci.RuntimeConfig, rootFs vc.RootFs,
	containerID, bundlePath string, disableOutput, systemdCgroup bool) (_ vc.VCSandbox, _ vc.Process, err error)

CreateSandbox create a sandbox container

func EnterNetNS ¶

func EnterNetNS(networkID string, cb func() error) error

EnterNetNS is free from any call to a go routine, and it calls into runtime.LockOSThread(), meaning it won't be executed in a different thread than the one expected by the caller.

func FileExists ¶

func FileExists(path string) bool

FileExists test is a file exiting or not

func GetDefaultConfigFilePaths ¶

func GetDefaultConfigFilePaths() []string

GetDefaultConfigFilePaths returns a list of paths that will be considered as configuration files in priority order.

func GetDefaultHypervisorConfig ¶

func GetDefaultHypervisorConfig() vc.HypervisorConfig

func GetFileContents ¶

func GetFileContents(file string) (string, error)

GetFileContents return the file contents as a string.

func HandleFactory ¶

func HandleFactory(ctx context.Context, vci vc.VC, runtimeConfig *oci.RuntimeConfig)

HandleFactory set the factory

func IsBlockDevice ¶

func IsBlockDevice(filePath string) bool

IsBlockDevice returns true if the give path is a block device

func LoadConfiguration ¶

func LoadConfiguration(configPath string, ignoreLogging bool) (resolvedConfigPath string, config oci.RuntimeConfig, err error)

LoadConfiguration loads the configuration file and converts it into a runtime configuration.

If ignoreLogging is true, the system logger will not be initialised nor will this function make any log calls.

All paths are resolved fully meaning if this function does not return an error, all paths are valid at the time of the call.

func PostStartHooks ¶

func PostStartHooks(ctx context.Context, spec specs.Spec, cid, bundlePath string) error

PostStartHooks run the hooks just after start container

func PostStopHooks ¶

func PostStopHooks(ctx context.Context, spec specs.Spec, cid, bundlePath string) error

PostStopHooks run the hooks after stop container

func PreStartHooks ¶

func PreStartHooks(ctx context.Context, spec specs.Spec, cid, bundlePath string) error

PreStartHooks run the hooks before start container

func ResolvePath ¶

func ResolvePath(path string) (string, error)

ResolvePath returns the fully resolved and expanded value of the specified path.

func SetConfigOptions ¶

func SetConfigOptions(n, runtimeConfig, sysRuntimeConfig string)

SetConfigOptions will override some of the defaults settings.

func SetEphemeralStorageType ¶

func SetEphemeralStorageType(ociSpec specs.Spec, disableGuestEmptyDir bool) specs.Spec

SetEphemeralStorageType sets the mount type to 'ephemeral' if the mount source path is provisioned by k8s for ephemeral storage. For the given pod ephemeral volume is created only once backed by tmpfs inside the VM. For successive containers of the same pod the already existing volume is reused.

func SetKernelParams ¶

func SetKernelParams(runtimeConfig *oci.RuntimeConfig) error

SetKernelParams adds the user-specified kernel parameters (from the configuration file) to the defaults so that the former take priority.

func SetLogger ¶

func SetLogger(ctx context.Context, logger *logrus.Entry, level logrus.Level)

SetLogger sets the logger for the factory.

func SetupNetworkNamespace ¶

func SetupNetworkNamespace(config *vc.NetworkConfig) error

SetupNetworkNamespace create a network namespace

func VerifyContainerID ¶

func VerifyContainerID(id string) error

VerifyContainerID checks if the specified container ID (or sandbox ID) is valid.

func WriteFile ¶

func WriteFile(filePath string, data string, fileMode os.FileMode) error

WriteFile write data into specified file
