Hi there

What determines if docker is mapped like this

127.0.0.1:32899->80/tcp, 127.0.0.1:32898->8443/tcp

or like this


e55609449eec varnish:7.3.1 "/usr/local/bin/dock…" 11 days ago Up 12 hours 0

it seems to select these at random?

127.0.0.1:32899->80/tcp, 127.0.0.1:32898->8443/tcp

v

0.0.0.0:32781->80/tcp, :::32771->80/tcp, 0.0.0.0:32779->8443/tcp, :::32770->8443/tcp

Despite all the settings in the container being identical
