Using Invoker to run kubernetes locally for development

I use Invoker for running Kubernetes locally while developing Kubernetes. It is relatively simple setup and unlike ./hack/local-up-cluster.sh doesn't involve any magical bits that my tiny brain can't understand. It is basically all kubernetes components started and running individually.

You can use following instructions for running kubenetes locally. Just don't forget to change hostname (xaos.lan to match your hostname). Similarly change ip address used here - "192.168.1.71" to your machine's IP address and similarly location of etcd and kubernetes binaries.

  1. Install Invoker ~> gem install invoker

  2. Compile kube ~> cd kube_home; make

For a lot of distros the /etc/resolv.conf is autogenerated by NetworkManager or dhcp-client, in those cases usually
/etc/resolv.conf contains a warning like:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

Traditionally, the file /etc/resolv.conf was a static configuration file that rarely needed to be
