How to do docker build image from dockerfile on Kubernetes 1.20

Question

Kubernetes 1.20 moved from docker to CRI-O as container runtime. I have a scenario where my Jenkins run on kubernetes and does docker build my dockerfile .But the build breaks as docker daemon is not available now. I tried using Kaniko to build image but the downfall was once image is built i have no chance to scan the image before pushing to container registry. Once the image is built i have to push it immediately. How can i scan it before pushing to registry.

Current process:

1. Jenkins runs on Kubernetes.
2. Pulls code and does the docker build and tag it.
3. Once docker build is successful will a scan the image for vulnerabilities.
4. Once scan passes we push to the container registry.

With Kaniko i can do till step 2 later image goes away I am not able to find the image locally but i can push directly. And pull it and do scan. Any suggestions or alternatives so i can use my old dockerfiles build,scan and push without major changes

You can take a look at podman, is like run docker but without the need of a daemon.
