Do you get the same error if you create a machine directly using docker-machine create -d xhyve? In the past this has been an issue with either docker-machine or the xhyve driver, I'm not sure which, and it doesn't seem to affect everybody. It might be worth checking if there's a related issue open with either of those projects.

qkdreyer · 2019-03-18T16:46:37Z

Can I check if setting up DNS resolution, this will require sudo succeded ?

qkdreyer · 2019-03-18T16:50:35Z

I'm wondering why I'm not seeing

dinghy/cli/dinghy/http_proxy.rb

Lines 92 to 94 in 1a4270e

  # Generated by dinghy 

  nameserver #{machine.vm_ip} 

  port 19322

dinghy ssh cat /etc/resolv.conf
nameserver 192.168.64.1

codekitchen · 2019-03-18T19:33:17Z

Darn yeah, this is what I've seen a couple times before. I wish I knew what was causing it, or even whether it was docker-machine vs the xhyve driver.

That resolver file isn't installed on the VM, it is installed on the MacOS host in /etc/resolver/docker, this is why you can reach *.docker domains from your host machine (e.g. Safari) and not just from other Docker containers.

qkdreyer · 2019-03-19T08:51:57Z

Can't you think about anything you want me to test to find out where that problem is ?

codekitchen · 2019-03-19T19:34:54Z

I'm not in a great position to figure this one out, I'm afraid. It might be useful to test with Virtualbox, see if you get the same problem with docker-machine create -d virtualbox. That won't guarantee whether it's a problem with the specific driver vs docker-machine itself, but it could still be a useful data point.

Then I'd file an issue with either the docker-machine-driver-xhyve project or the docker-machine project, or look for an existing issue.

qkdreyer · 2019-03-20T15:34:58Z

Doing a macOS reboot handled the NFS issues (port 19091 was still used by a dead process, invisible using lsof, shown using netstat)

I was still having issues with DNS, which I solved by using 192.16.8.1.1 instead of 192.168.64.1 as resolver.

dinghy ssh nslookup docker.io                                                                                             ✔  10013  16:34:06
Server:    192.168.64.1
Address 1: 192.168.64.1

nslookup: can't resolve 'docker.io'
exit status 1

dinghy ssh "echo 'nameserver 192.168.1.1' | sudo tee /etc/resolv.conf"

dinghy ssh nslookup docker.io                                                                                             ✔  10016  16:34:30

I've just found out what the real DNS problem was.
I had already a local dnsmasq installed, which was not listening to docker interfaces.

After running these commands, no more DNS issues inside dinghy :

echo 'listen-address=127.0.0.1' >> /usr/local/etc/dnsmasq.conf
echo 'listen-address=192.168.64.1' >> /usr/local/etc/dnsmasq.conf
sudo brew services restart dnsmasq
