cri-tools: crictl images can not find local image loaded by podman

Just take a look at the following commands and the result:

# podman images localhost/vanlos/vanlos-builder:latest
REPOSITORY                                                 TAG        IMAGE ID       CREATED       SIZE
localhost/vanlos/vanlos-builder   latest     efe2b0dfd8b8   6 days ago    601 MB
# podman images vanlos/vanlos-builder:latest
REPOSITORY                                                 TAG        IMAGE ID       CREATED       SIZE
localhost/vanlos/vanlos-builder   latest     efe2b0dfd8b8   6 days ago    601 MB
# crictl images localhost/vanlos/vanlos-builder:latest
REPOSITORY                                                 TAG        IMAGE ID       CREATED       SIZE
localhost/vanlos/vanlos-builder   latest     efe2b0dfd8b8   6 days ago    601 MB
# crictl images vanlos/vanlos-builder:latest
IMAGE               TAG                 IMAGE ID            SIZE

crictl images will not find local image without the prefix of ‘localhost/’, then it will make k8s always try to pull image to start a pod, but the image is locally.

My OS is CentOS 7.5, and cri utils infomations are as following:

# crictl version
Version:  0.1.0
RuntimeName:  cri-o
RuntimeVersion:  1.11.10
RuntimeApiVersion:  v1alpha1
# rpm -qa | grep cri-tools
cri-tools-1.11.1-1.rhaos3.11.gitedabfb5.el7.x86_64.rpm
# rpm -qa | grep cri-o
cri-o-1.11.10-1.rhaos3.11.git42c86f0.el7.x86_64.rpm

it seems that podman loaded the image at $HOME/.local/share/containers/storage/overlay/

Yep you have to run podman as root, otherwise it will choose the local storage 😃

Awesome! 👍

And here you get “Sascha’s tip of the day”: You can load the image via

sudo podman -i image.tar

too! 😇

@vanloswang, I suspect that cri-o and podman are configured to use different directories for storing images. You can check that in the corresponding configs (i.e., /etc/crio/crio.conf and /etc/containers/storage.conf). It’s also important to execute podman as root since rootless images are stored somewhere else.
