Network bridge on host

[elao]

After reading all the related forum threads, i still don’t get it: do docker mac beta is supposed to set a docker0 bridge interface on the osx host, like it does on linux, so that containers are directly available from host via their local network ip ?

Or this bridge is only set/available on the alpine vm itself ?

Currently the only way to access containers is by exposing a port.
See https://beta.docker.com/docs/mac/getting-started/#step-3-explore-the-application-and-run-examples. There is no docker0 on the Mac.

Then how can I access VPN? Can you please guide me?

This feature request is related to the following topic:

Support tap interface for direct container access (incl. multi-host)

+1 on this feature I thought this was a hyperkit limitation but it turned out to be a configuration ability issue (or lack there of) reference here: https://github.com/docker/hyperkit/issues/45 Though it would be ideal that docker comes with tap interfaces installed similar to VirtualBox and VMWare. Worst case scenario we should be able to extend the feature set of Moby if the feature is available via third party software (brew install tuntap).

When a container configured for network_mode: host in docker-compose, for example, I can’t expose ports as usually adviced. What else can I do?

For those who haven’t yet got a working solution for this, I have created a shim workaround for this issue in this project. It behaves the exact same as the hvint0 interface on Windows

@strayerror @michaelhenkel @dimitrasz I just pushed up my version of the shim installer here https://github.com/AlmirKadric-Published/docker-tuntap-osx. I chose not to contribute to your shim installer @strayerror as my version works a little differently in terms of the architecture as it doesn’t bring up a docker network (this pollutes the iptables with forward blocking) which results in having to keep your containers on that networks subnet. Instead it creates a full bridge allowing you to cr…

Honestly the fact this issue hasn’t been fixed is ridiculous so I plan to make some waves with this package. Request to update docs here:

Please up-vote and comment your support so that this issue gets the attention it deserves
