Cannot access randomly selected port

kaskavalci commented 2 years ago

When a container is started without host port, it is not accessible via lima.

$ docker run -d -p 80 nginx:alpine
aece04c330bd262ab2ab6b07bb8f30f41b5ce96aab2339ae743689ae093ccd88
$ docker ps

It seems even though they are started with a specific host port, when that port was used before, it is still not available.

$ docker run -d -p 49200:80 nginx:alpine

With rootful docker or rootless docker?

Could you provide the output of docker info (or just Lima yaml) and Lima version?

I am using examples/docker so it seems it is rootless. I am using lima 0.8.0. Below is the docker info information.
