How about that touch bar

How about that touch bar?. That's a rhetorical question, because Apple doesn't care about your answer. They basically engineer to some ideal, then tell testers "use this until you change your mind about it." The design is set, the only point of the test is to discover how long it takes for people to accept it. "Hey here's an ipod with no buttons, how long did it take for you to forget what a scroll wheel was like?" Best believe I hate this touch bar. But Apple knows how long it will take before I stop hating it so they don't care. Well. Guess what. I found the hole in the loop. You can't get a person used to something they don't use.

Speaking of brain washing. How bout the singularity. Touch bar is just the start. I guarantee everything is conforming to the ipad mini. Phone getting bigger, laptops getting smaller. Less and less buttons more and more glass. All the testers kicking and screaming with their top secret unrelea

Life & times of an AKS disk mount
  1. PV Disk is created. Unattached to any vm
  2. Pod is created

NixOS kubernetes and iptables

tldr; try this: sudo iptables -D INPUT -j nixos-fw

Nix firewall chain drops connections from the kubedns Pod's attempt to contact api server.

This results in timeouts:

Installing Docker-CE on RHEL 7.4

Please notice that while Docker-CE is not supported for RHEL, if you still want to install it the RedHat 'extras' channel is as of version 17.06 a prerequisite that provides the container-selinux package. @NBardelot

# get docker ce
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum makecache fast

# install container-selinux
