It can contain one or multiple containers (usually Docker containers), and these containers within a pod share resources like networking and storage. Containers in the same pod can communicate with each other using localhost, as they share the same network namespace. ...

Example use case Say you have developed a drawing or mindmap in Excalidraw. You can export this to SVG and then run the command to convert it to PDF. Very cool! ...
