Can I share a network between 2 rootless instances?

Hello,

I have a machine with some users, all are rootless. Example:

  • user1 container1 HAproxy
  • user2 container2 Nginx

How can I create a network for both containers. Rootless isolates networks, but I need HAproxy communicate with backend Nginx.

How can I share a network between 2 rootless instances?

Thank you
