And as such, you can use it as a replacement for generic tools like Docker and Podman. So that means that for basic container management and investigation, you don't need Docker and Podman, you just need crictl. To use it, you'll need to set a runtime-endpoint and an image-endpoint. The most convenient way to do so is by defining the /etc/crictl.yaml file on the nodes where you want to run crictl. In the course, git repository, I'm providing an example of this YAML file. Probably you want to fetch this YAML file so that you don't have to create it for yourself. All right, let me continue and let me show you some crictl. Here on the slide, you can see the commands that I'm going to run for you. So let me start with sudo crictl…
