func ContainerConfig

func ContainerConfig(ocispec specs.Spec, bundlePath, cid, console string, detach bool) (vc.ContainerConfig, error)

ContainerConfig converts an OCI compatible runtime configuration file to a virtcontainers container configuration structure.

func ContainerType

func ContainerType(spec specs.Spec) (vc.ContainerType, error)

ContainerType returns the type of container and if the container type was found from CRI servers annotations.

func EnvVars

func EnvVars(envs []string) ([]types.EnvVar, error)

EnvVars converts an OCI process environment variables slice into a virtcontainers EnvVar slice.

func GetContainerType

func GetContainerType(annotations map[string]string) (vc.ContainerType, error)

GetContainerType determines which type of container matches the annotations table provided.

func GetOCIConfig

func GetOCIConfig(status vc.ContainerStatus) (specs.Spec, error)

GetOCIConfig returns an OCI spec configuration from the annotation stored into the container status.

func GetSandboxConfigPath

func GetSandboxConfigPath(annotations map[string]string) string

func SandboxConfig

func SandboxConfig(ocispec specs.Spec, runtime RuntimeConfig, bundlePath, cid, console string, detach, systemdCgroup bool) (vc.SandboxConfig, error)

SandboxConfig converts an OCI compatible runtime configuration file to a virtcontainers sandbox configuration structure.

func SandboxID

func SandboxID(spec specs.Spec) (string, error)

SandboxID determines the sandbox ID related to an OCI configuration. This function is expected to be called only when the container type is "PodContainer".

func SetLogger

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

SetLogger sets the logger for oci package.

func StateToOCIState

func StateToOCIState(state types.StateString) string

StateToOCIState translates a virtcontainers container state into an OCI one.

func StatusToOCIState

func StatusToOCIState(status vc.ContainerStatus) specs.State

StatusToOCIState translates a virtcontainers container status into an OCI state.


type FactoryConfig

type FactoryConfig struct {
	// Template enables VM templating support in VM factory.
	Template bool

	// TemplatePath specifies the path of template.
	TemplatePath string

	// VMCacheNumber specifies the the number of caches of VMCache.
	VMCacheNumber uint

	// VMCacheEndpoint specifies the endpoint of transport VM from the VM cache server to runtime.
	VMCacheEndpoint string

FactoryConfig is a structure to set the VM factory configuration.

type RuntimeConfig

type RuntimeConfig struct {
	HypervisorType   vc.HypervisorType
	HypervisorConfig vc.HypervisorConfig

	NetmonConfig vc.NetmonConfig

	AgentType   vc.AgentType
	AgentConfig interface{}

	//the container network interface
	InterNetworkModel vc.NetInterworkingModel
	FactoryConfig     FactoryConfig
	Debug             bool
	Trace             bool

	DisableNewNetNs bool

	//Determines kata processes are managed only in sandbox cgroup
	SandboxCgroupOnly bool

	//Experimental features enabled
	Experimental []exp.Feature

RuntimeConfig aggregates all runtime specific settings

func (*RuntimeConfig) AddKernelParam

func (config *RuntimeConfig) AddKernelParam(p vc.Param) error

AddKernelParam allows the addition of new kernel parameters to an existing hypervisor configuration stored inside the current runtime configuration.
