Debug a Google Cloud VM Machine
Can't access app deployed with docker and google cloud First, test to see if your service works at all. To do this, from the VM itself, run: wget http://localhost: 32768 or curl http://localhost: 32768 If that works, that means the service is operating properly, so let's move further with the debugging. There may be two firewalls that are blocking external access to your docker process: the VM's OS firewall Google Compute Engine firewall You can see if you're affected by the first issue by accessing the URL from the VM itself and from another VM on the same GCE network (use the VM name in the URL, not the external IP): wget http://[vm-name]: 32768 To fix the first issue, you would have to either open up the single port (recommended): iptables -I INPUT -p tcp -s 0.0 .0 .0 / 0 --dport 32768 -j ACCEPT or disable firewall entirely, e.g., by stopping iptables (not recommended). If, after fixing this, you can access the URL from another host on the same GCE network, bu...
