I use this tool all the time. Mainly for running various LLM cli tools and whatnot. No way will I install those tools on my host OS due to my unfounded paranoia.
Container still has a few warts. Mainly, Container and mDNSResponder on macOS do not always play nicely together. If you use a VPN that binds to port 53, you will also have a bad time. Container-to-Container name resolution is also hit or miss.
However, none of these issues have prevented me from accomplishing what I need. Though, I can see where friction may arise between some corporate network environments and Container.
