PodmanClient

bootc_lib::podman_client

Struct PodmanClient 

Source 
pub(crate) struct PodmanClient {
    service_child: Child,
    socket_path: String,
    sysroot: Dir,
    storage_root: Dir,
    run_root: Dir,
}
Expand description

Manages a transient podman service, providing HTTP access to the native libpod API via a Unix socket.

Fields§

§service_child: Child§socket_path: String

Filesystem path to the socket.

§sysroot: Dir

Stored for subprocess fallback when the image transport is not supported by the libpod HTTP API (which only handles docker:).

§storage_root: Dir§run_root: Dir

Implementations§

Source§

impl PodmanClient

Source

pub(crate) async fn connect( sysroot: &Dir, storage_root: &Dir, run_root: &Dir, ) -> Result<Self>

Start a transient podman system service pointing at the given storage root and connect to it.

Registry auth is configured via REGISTRY_AUTH_FILE on the podman service process, using the same bootc/ostree auth as existing podman CLI invocations.

Source

pub(crate) async fn pull_with_progress(&self, image: &str) -> Result<()>

Pull a container image with streaming progress display.

Uses the native podman libpod API (/libpod/images/pull) which provides real download progress (bytes transferred) on podman 5.9+ (see containers/podman#28224). On older podman, status messages (“Copying blob …”, “Writing manifest …”) are shown as a spinner.

The libpod HTTP API only supports the docker: transport. When the image reference uses a different transport (oci:, dir:, containers-storage:, etc.) we fall back to invoking podman pull as a subprocess with the same storage and auth configuration.

Registry authentication is handled by the podman service process via REGISTRY_AUTH_FILE, configured at connect() time.

Source

async fn pull_via_api(&self, image: &str) -> Result<()>

Pull using the libpod HTTP API (docker transport only).

Source

async fn pull_via_subprocess(&self, image: &str) -> Result<()>

Fallback: pull via podman pull subprocess for non-docker transports.

The libpod HTTP API only supports docker: transport, so transports like oci:, dir:, containers-storage:, etc. are handled by shelling out to podman pull with the same storage and auth configuration used by the API service.
