I understand what 'network_mode: host' does and that there's some underlying issues with Docker for Mac and this. But wondering if there is an answer that I haven't yet found. Basically I have 3 containers: A, B and C. Video format converter for windows 7. C depends on B and B on A. C is a React app so I need to be able to access it in my browser, I don't care so much about B & A being reachable by the host. What I've tried is: • Connecting all the containers to A's network ('network_mode: container:A' on B & C) • Creating a network and associating all of the containers with this network • Use 'network_mode:host' What I need is for A & B to be reachable by localhost to C due to how the project was created (and this is for work, not something I can just change w/o a bunch of pushback).

I can't exactly do the custom network thing unless I can associate all of the containers to the IP (which they don't use the same port), not sure how/if this is possible. But I do have a network created for this. So when I tried the first route it worked for the most part, but C has a secondary dependency on a redis image being running, which caused some issues.

Mac Some VPN software prevents access to local network resources. Samsung 500gb 970 evo nvme m2 for mac. Docker­ Machine setup creates a Virtualbox host-­only network, which is essentially a 'local network.' Docker for Mac makes whatever is running on port 80 in the container (in this case, nginx) available on port 80 of localhost. In this example, the host and container ports are the same. In this example, the host and container ports are the same.

A co-worker told me to use host networking mode, and it's worked almost completely flawlessly. I tried accessing it via localhost, IP of host, IP of Docker for Mac (which I've dug up as 192.168.65.1 or.2). Everything but the last has yielded immediate 'unable to reach host', where as if I use the IP for Docker for Mac it at least tries for a while before telling me operation timed out (via cURL call). I don't have a firewall going on and no VPN either right now. I'm not expecting to see glory but would at least be able to see some response from the container.
