[Podman] Inter-container communication in pod

Hi, I have a situation in which I have React app in container, which is exposed to port 3000 to be able to access it from host and I also have another container for Express API server, which is listening on port 8000, but I don't want it to be accessible from host. Is it somehow possible to run these two containers simultaneously in one pod and have exposed only port 3000, so we can see the page? Thanks for a reply. Best regards, Dominik Matis
