Functions ¶

func NumCPU ¶

func NumCPU() int

NumCPU returns the number of CPUs

Types ¶

type SysInfo ¶

type SysInfo struct {
	// Whether the kernel supports AppArmor or not
	AppArmor bool
	// Whether the kernel supports Seccomp or not
	Seccomp bool

	// Whether IPv4 forwarding is supported or not, if this was disabled, networking will not work
	IPv4ForwardingDisabled bool

	// Whether bridge-nf-call-iptables is supported or not
	BridgeNFCallIPTablesDisabled bool

	// Whether bridge-nf-call-ip6tables is supported or not
	BridgeNFCallIP6TablesDisabled bool

	// Whether the cgroup has the mountpoint of "devices" or not
	CgroupDevicesEnabled bool
	// contains filtered or unexported fields
}

SysInfo stores information about which features a kernel supports. TODO Windows: Factor out platform specific capabilities.

func New ¶

func New(quiet bool) *SysInfo

New returns an empty SysInfo for non linux nor solaris for now.

func (SysInfo) IsCpusetCpusAvailable ¶

func (c SysInfo) IsCpusetCpusAvailable(provided string) (bool, error)

IsCpusetCpusAvailable returns `true` if the provided string set is contained in cgroup's cpuset.cpus set, `false` otherwise. If error is not nil a parsing error occurred.

func (SysInfo) IsCpusetMemsAvailable ¶

func (c SysInfo) IsCpusetMemsAvailable(provided string) (bool, error)

IsCpusetMemsAvailable returns `true` if the provided string set is contained in cgroup's cpuset.mems set, `false` otherwise. If error is not nil a parsing error occurred.
