Dear StackOverflow community!
I am trying to run the https://github.com/GoogleCloudPlatform/microservices-demo locally on minikube, so I am following their development guide: https://github.com/GoogleCloudPlatform/microservices-demo/blob/master/docs/development-guide.md
After I successfully set up minikube (using virtualbox driver, but I tried also hyperkit, however the results were the same) and execute skaffold run, after some time it will end up with following error:
Building [shippingservice]...

The error message suggest that DNS does not work. I tried to add 8.8.8.8 to /etc/resolv.conf on a minikube VM, but it did not help. I've noticed that after I re-run skaffold run and it fails again, the content /etc/resolv.conf returns to its original state containing 10.0.2.3 as the only DNS entry. Reaching the outside internet and pinging 8.8.8.8 form within the minikube VM works.
Could you point me to a direction how can possible I fix the problem and learn on how the DNS inside minikube/kubernetes works? I've heard that problems with DNS inside Kubernetes cluster are frequent problems you run into.
Thanks for your answers!
Best regards, Richard
Tried it with docker driver, i.e. minikube start --driver=docker, and it works. Thanks Brian!
