Overview ¶
Package features provides the JSON structure that is printed by `runc features` (since runc v1.1.0). The types in this package are experimental and subject to change.

const ( // AnnotationRuncVersion represents the version of runc, e.g., "1.2.3", "1.2.3+dev", "1.2.3-rc.4.", "1.2.3-rc.4+dev". // Third party implementations such as crun and runsc MAY use this annotation to report the most compatible runc version, // however, parsing this annotation value is discouraged. AnnotationRuncVersion = "org.opencontainers.runc.version" // AnnotationRuncCommit corresponds to the output of `git describe --dirty --long --always` in the runc repo. // Third party implementations such as crun and runsc SHOULD NOT use this annotation, as their repo is different from the runc repo. // Parsing this annotation value is discouraged. AnnotationRuncCommit = "org.opencontainers.runc.commit" // AnnotationRuncCheckpointEnabled is set to "true" if CRIU-based checkpointing is supported. // Unrelated to whether the host supports CRIU or not. // Always set to "true" in the current version of runc. // This is defined as an annotation because checkpointing is a runc-specific feature that is not defined in the OCI Runtime Spec. // Third party implementations such as crun and runsc MAY use this annotation. AnnotationRuncCheckpointEnabled = "org.opencontainers.runc.checkpoint.enabled" // AnnotationLibseccompVersion is the version of libseccomp, e.g., "2.5.1". // Note that the runtime MAY support seccomp even when this annotation is not present.

Types ¶
type Apparmor ¶
type Apparmor struct {
// Enabled is true if AppArmor support is compiled in.
// Unrelated to whether the host supports AppArmor or not.
// Nil value means "unknown", not "false".
// Always true in the current version of runc.
Enabled *bool `json:"enabled,omitempty"`
}
Apparmor represents the "apparmor" field.
type Cgroup ¶
type Cgroup struct {
// V1 represents whether Cgroup v1 support is compiled in.
// Unrelated to whether the host uses cgroup v1 or not.
// Nil value means "unknown", not "false".
// Always true in the current version of runc.
V1 *bool `json:"v1,omitempty"`
// V2 represents whether Cgroup v2 support is compiled in.
// Unrelated to whether the host uses cgroup v2 or not.
// Nil value means "unknown", not "false".
// Always true in the current version of runc.
V2 *bool `json:"v2,omitempty"`
// Systemd represents whether systemd-cgroup support is compiled in.
// Unrelated to whether the host uses systemd or not.
// Nil value means "unknown", not "false".
// Always true in the current version of runc.
Systemd *bool `json:"systemd,omitempty"`
// SystemdUser represents whether user-scoped systemd-cgroup support is compiled in.
// Unrelated to whether the host uses systemd or not.
// Nil value means "unknown", not "false".
// Always true in the current version of runc.
SystemdUser *bool `json:"systemdUser,omitempty"`
}
Cgroup represents the "cgroup" field.
type Features ¶
type Features struct {
// OCIVersionMin is the minimum OCI Runtime Spec version recognized by the runtime, e.g., "1.0.0".
OCIVersionMin string `json:"ociVersionMin,omitempty"`
// OCIVersionMax is the maximum OCI Runtime Spec version recognized by the runtime, e.g., "1.0.2-dev".
OCIVersionMax string `json:"ociVersionMax,omitempty"`
// Hooks is the list of the recognized hook names, e.g., "createRuntime".
// Nil value means "unknown", not "no support for any hook".
Hooks []string `json:"hooks,omitempty"`
// MountOptions is the list of the recognized mount options, e.g., "ro".
// Nil value means "unknown", not "no support for any mount option".
// This list does not contain filesystem-specific options passed to mount(2) syscall as (const void *).
MountOptions []string `json:"mountOptions,omitempty"`
// Linux is specific to Linux.
Linux *Linux `json:"linux,omitempty"`
// Annotations contains implementation-specific annotation strings,
// such as the implementation version, and third-party extensions.
Annotations map[string]string `json:"annotations,omitempty"`
}
Features represents the supported features of the runtime.
type Linux ¶
type Linux struct {
// Namespaces is the list of the recognized namespaces, e.g., "mount".
// Nil value means "unknown", not "no support for any namespace".
Namespaces []string `json:"namespaces,omitempty"`

// Nil value means "unknown", not "false".
Enabled *bool `json:"enabled,omitempty"`
// Actions is the list of the recognized actions, e.g., "SCMP_ACT_NOTIFY".
// Nil value means "unknown", not "no support for any action".
Actions []string `json:"actions,omitempty"`
// Operators is the list of the recognized actions, e.g., "SCMP_CMP_NE".
// Nil value means "unknown", not "no support for any operator".
Operators []string `json:"operators,omitempty"`
// Operators is the list of the recognized archs, e.g., "SCMP_ARCH_X86_64".
// Nil value means "unknown", not "no support for any arch".
Archs []string `json:"archs,omitempty"`
}
Seccomp represents the "seccomp" field.
type Selinux ¶
type Selinux struct {
// Enabled is true if SELinux support is compiled in.
// Unrelated to whether the host supports SELinux or not.
// Nil value means "unknown", not "false".
// Always true in the current version of runc.
Enabled *bool `json:"enabled,omitempty"`
}
Selinux represents the "selinux" field.
