interface tap1 does not exist #6

Closed murtyjones closed 2 years ago

Hi -

I cloned this repository down in an attempt to install it. Unfortunately, it errors out at this point:

Bridge tap into docker network
Assign the network gateway IP to the tap interface
**ifconfig: interface tap1 does not exist**

Has anyone fixed this previously?

macOS Sierra (10.12.6) Docker version:

Does /dev/tap1 exist on your system? If not try visiting and installing tuntaposx following their instructions and then try again.

Do you always see the message "Install tuntap kernel extension" when running install.sh? This suggests that the tuntaposx driver is either not installed, or not being recognised as a character device (read on).

Is /dev/tap1 correctly identified as a character device? Test this by running: test -c /dev/tap1; echo $?, you're hoping for a 0. If you see something else but /dev/tap1 exists, try:

  1. Remove this line from install.sh
  2. Run install.sh again (failure expected)
  3. Restart Docker via the tray
  4. Run install.sh again (hopefully success)

Hey, thanks for the quick reply.

Looks like /dev1/tap1 exists/ and is identified as a character device.

Could you try doing just steps 3 and 4 and see if that helps? It's possible docker did not activate the tap1 interface or that you missed the restart docker prompt on your inital run of install.sh.
