type Opt ¶
type Opt func(info *SysInfo)
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
//
// Deprecated: netfilter module is now loaded on-demand and no longer during daemon startup, making this field obsolete. This field is always false and will be removed in the next release.
BridgeNFCallIPTablesDisabled bool
// Whether bridge-nf-call-ip6tables is supported or not
//
// Deprecated: netfilter module is now loaded on-demand and no longer during daemon startup, making this field obsolete. This field is always false and will be removed in the next release.
BridgeNFCallIP6TablesDisabled bool
// Whether the cgroup has the mountpoint of "devices" or not
CgroupDevicesEnabled bool
// Whether the cgroup is in unified mode (v2).
CgroupUnified bool
// Warnings contains a slice of warnings that occurred while collecting
// system information. These warnings are intended to be informational
// messages for the user, and can either be logged or returned to the
// client; they are not intended to be parsed / used for other purposes,
// and do not have a fixed format.
Warnings []string
// 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.
func (SysInfo) IsCpusetCpusAvailable ¶
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 ¶
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.
