From 756ecd5400c7a8806890753d4f9fbb2b39eba192 Mon Sep 17 00:00:00 2001 From: Radostin Stoyanov Date: Tue, 12 Apr 2022 18:46:32 +0100 Subject: Add support for checkpoint image This is an enhancement proposal for the checkpoint / restore feature of Podman that enables container migration across multiple systems with standard image distribution infrastructure. A new option `--create-image ` has been added to the `podman container checkpoint` command. This option tells Podman to create a container image. This is a standard image with a single layer, tar archive, that that contains all checkpoint files. This is similar to the current approach with checkpoint `--export`/`--import`. This image can be pushed to a container registry and pulled on a different system. It can also be exported locally with `podman image save` and inspected with `podman inspect`. Inspecting the image would display additional information about the host and the versions of Podman, criu, crun/runc, kernel, etc. `podman container restore` has also been extended to support image name or ID as input.
