如何在无根 podman 中发布用户定义网络中的端口？

Question

I'm trying to publish ports to host from the container, but it does not work when the container is being run with the user defined network. See below:

$ podman network create samplenet
$ podman network ls              
NAME       VERSION  PLUGINS
samplenet  0.4.0    bridge,portmap,firewall,tuning,dnsname
$ podman run -dt --name test --network=samplenet --rm --publish 8080:80 nginx
$ podman port -l   
80/tcp -> 0.0.0.0:8080
$ curl localhost:8080
curl: (56) Recv failure: Connection reset by peer

I've noticed that network mode for containers without network specified is slirp4netns , but when I specify a network it is changed to: bridge .

How can I expose ports from the container and connect it to the user-defined network in rootless mode?

That's a bug in podman 3.0.1. Fixed in 3.1.0.
