type Opt ¶
type Opt func(*opts)
Opt for New().
func WithCgroup2GroupPath ¶
WithCgroup2GroupPath specifies the cgroup v2 group path to inspect availability of the controllers.
WithCgroup2GroupPath is expected to be used for rootless mode with systemd driver.
e.g. g = "/user.slice/user-1000.slice/user@1000.service"
type SysInfo ¶
type SysInfo struct {
// Whether the kernel supports AppArmor or not
AppArmor bool
// Whether the kernel supports Seccomp or not
Seccomp bool
// Whether the kernel supports cgroup namespaces or not
CgroupNamespaces 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
// Whether the cgroup is in unified mode (v2).
CgroupUnified bool
// contains filtered or unexported fields
}
SysInfo stores information about which features a kernel supports. TODO Windows: Factor out platform specific capabilities.
func New ¶
New returns a new SysInfo, using the filesystem to detect which features the kernel supports. If `quiet` is `false` warnings are printed in logs whenever an error occurs or misconfigurations are present.
func (SysInfo) IsCpusetCpusAvailable ¶ added in v1.9.0
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 ¶ added in v1.9.0
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.
