CLI tool for fetching images for containerd

Author: Sravya Bandari

Date: January 20, 2024

Audience: Everyone

Environmental details: Self-hosted (KOTS) 9.6+ versions 

Summary: 

From version 9.6 of Jama, we have moved from docker to the containerd service on the application side. This document outlines the utility and documents for listing and removing images.

Solution:
We can use the crictl utility (will work for both Docker and ContainerD). Many commands used for docker are transferrable. E.g. docker ps becomes crictl ps

Some example commands:

sudo crictl images - for listings the images

sudo crictl rmi <image-name>:<tag> - for removing the image
