Hi, question from a sysadmin / network engineer. Why localhost with port forwarding? Why not native mechanism like routing and mdns? I’ve gave Docker and other container managers which do networking the same way a try a few times and I always found the network unnecessarily complicated. Eventually I came across OrbStack which uses the aforementioned mechanisms. Every container gets an IP address in the local bridge and responds to mdsns queries. This plays especially well in “compose” scenario when services on containers can all use original port numbers. And containers can be accessed with hostnames, so there won’t be conflict between port numbers especially if I run multiple composed stacks.
