Support to use crictl

[cmoulliard]

Request

On a linux machine where docker is not installed but containerd we can list/access the images using the tool crictl which is not supported by dive. Would it be possible to support it ?

crictl command

[snowdrop@h01-121 ~]$ sudo crictl images
WARN[0000] image connect using default endpoints: [unix:///var/run/dockershim.sock unix:///run/containerd/containerd.sock unix:///run/crio/crio.sock]. As the default settings are now deprecated, you should set the endpoint instead.

Letting you know also CRI-O images are not supported yet (ie: not built using docker/containerd/podman). Using SUDO or not.

Maybe a reference to the container runtime would help ?

Storage driver: overlayfs Runtime: crun CGroup driver: systemd

Using containers with following runtime endpoint: unix://var/run/crio/crio.sock

22:31 nuno-aj-aniceto ~/project-manager-api (git: main)
$ >> crictl images | grep project-manager
localhost/project-manager-api                              latest                     1576f79c52ad2       347MB

22:32 nuno-aj-aniceto ~/project-manager-api (git: main)
$ >> sudo dive localhost/project-manager-api
Image Source: docker://localhost/project-manager-api
Fetching image... (this can take a while for large images)

Notice: works with the flag "--source podman", the command works (as sudo as podman runs in rootless).

sudo dive --source podman localhost/project-manager-api
