Enum RootfsSource 

pub enum RootfsSource {
    Bind {
        path: PathBuf,
        follow_root_symlinks: bool,
    },
    Oci(OciRootfsSource),
    DiskImage {
        path: PathBuf,
        format: DiskImageFormat,
        fstype: Option<String>,
    },
}

Root filesystem source for a sandbox.

Variants

Bind

Use a host directory directly as the root filesystem.

Fields

path: PathBuf

Host path to bind mount.

follow_root_symlinks: bool

Whether to follow symlinks when resolving the host rootfs path.

Defaults to false: the path is resolved following no symlink in any component, matching the --mount protection, so a symlink at or under the rootfs path cannot redirect the mount. Set true to opt out when the host rootfs path legitimately traverses a symlink.

Oci(OciRootfsSource)

Use an OCI image reference with an EROFS lower and ext4 overlay upper.

DiskImage

Use a disk image file as the root filesystem via virtio-blk.

Fields

path: PathBuf

Path to the disk image file on the host.

format: DiskImageFormat

Disk image format.

fstype: Option<String>

Inner filesystem type (optional; auto-detected if absent).

Implementations

impl RootfsSource

pub fn oci(reference: impl Into<String>) -> Self

Create an OCI rootfs source from an image reference.

pub fn oci_reference(&self) -> Option<&str>

Return the OCI image reference if this is an OCI rootfs.

pub fn oci_root_disk(&self) -> Option<&RootDisk>

Return the configured root disk if this is an OCI rootfs.

pub fn oci_managed_root_disk_size_mib(&self) -> Option<u32>

Return the managed root disk size in MiB if this is an OCI rootfs with a managed (or unset, i.e. default-managed) root disk. Non-managed kinds return None.

Trait Implementations

impl Clone for RootfsSource

fn clone(&self) -> RootfsSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RootfsSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RootfsSource

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RootfsSource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for RootfsSource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
