const UVMContainerID = "00000000-0000-0000-0000-000000000000"
UVMContainerID is the ContainerID that will be sent on any prot.MessageBase for V2 where the specific message is targeted at the UVM itself.

Functions ¶
func GetOrAddNetworkNamespace ¶ added in v0.10.0
func GetOrAddNetworkNamespace(id string) *namespace
GetOrAddNetworkNamespace returns the namespace found by `id` or creates a new one and assigns `id.
Types ¶
type Container ¶
type Container struct {
// contains filtered or unexported fields
}
func (*Container) ExecProcess ¶
func (*Container) GetAllProcessPids ¶
GetAllProcessPids returns all process pids in the container namespace.
func (*Container) GetProcess ¶
GetProcess returns the Process with the matching 'pid'. If the 'pid' does not exit returns error.
func (*Container) GetStats ¶
GetStats returns the cgroup metrics for the container. Works with both cgroup v1 and v2 systems.
func (*Container) InitProcess ¶ added in v0.10.0
InitProcess returns the container's init process
func (*Container) Wait ¶
func (c *Container) Wait() prot.NotificationType
Wait waits for the container's init process to exit.
type Host ¶
type Host struct {
// contains filtered or unexported fields
}
Host is the structure tracking all UVM host state including all containers and processes.
func NewHost ¶
func NewHost(rtime runtime.Runtime, vsock transport.Transport, initialEnforcer securitypolicy.SecurityPolicyEnforcer, logWriter io.Writer) *Host
func (*Host) AddContainer ¶ added in v0.10.0
func (*Host) CreateContainer ¶
func (*Host) ExecProcess ¶ added in v0.10.0
func (h *Host) ExecProcess(ctx context.Context, containerID string, params prot.ProcessParameters, conSettings stdio.ConnectionSettings) (_ int, err error)
func (*Host) GetCreatedContainer ¶ added in v0.10.0
func (*Host) GetProperties ¶ added in v0.10.0
func (h *Host) GetProperties(ctx context.Context, containerID string, query prot.PropertyQuery) (*prot.PropertiesV2, error)
func (*Host) HasSecurityPolicy ¶
Returns whether this host has a security policy set, i.e. if it's running confidential containers.
func (*Host) ModifySettings ¶
func (h *Host) ModifySettings(ctx context.Context, containerID string, req *guestrequest.ModificationRequest) error
func (*Host) RemoveContainer ¶
func (*Host) SecurityOptions ¶
func (h *Host) SecurityOptions() *securitypolicy.SecurityOptions
func (*Host) SecurityPolicyEnforcer ¶ added in v0.10.0
func (h *Host) SecurityPolicyEnforcer() securitypolicy.SecurityPolicyEnforcer
func (*Host) Shutdown ¶
func (*Host) Shutdown()
Shutdown terminates this UVM. This is a destructive call and will destroy all state that has not been cleaned before calling this function.
func (*Host) ShutdownContainer ¶ added in v0.10.0
Called to shutdown a container
func (*Host) SignalContainerProcess ¶ added in v0.10.0
type Process ¶
type Process interface {
// Kill sends `signal` to the process.
//
// If the process has already exited returns `gcserr.HrErrNotFound` by contract.
Kill(ctx context.Context, signal syscall.Signal) error
// Pid returns the process id of the process.
Pid() int
// ResizeConsole resizes the tty to `height`x`width` for the process.
ResizeConsole(ctx context.Context, height, width uint16) error
// Wait returns a channel that can be used to wait for the process to exit
// and gather the exit code. The second channel must be signaled from the
// caller when the caller has completed its use of this call to Wait.
Wait() (<-chan int, chan<- bool)
}
