* Set theme jekyll-theme-tactile

* Create CNAME

* link to how to change size of video memory

Closes #1.

* Update mechanism to enable cgroup memory

See: raspberrypi/linux@ba742b5

* why not both?

I found the elimination of cgroup_enable=memory actually broke my raspbian kubernetes setup. putting both worked with my testing after reboot.

* Adding PR template

* Move TASK [Pass bridged IPv4 traffic to iptables' chains] after TASK [kubeadm : Run Docker Install Script]

* Changed networking from weave to flannel. Added version control for docker-ce, kubeadm, kubelet, kubectl, kubernetes images and flannel.

* Added cleanup playbook that removes kubernetes, all images, docker-ce, kubeadm, kubelet, kubectl and performs a reboot.

* Cleaning Up/Organizing/Adding Functionality

- Incorporate changes from #34
- Changing soon to be deprecated Ansible syntaxes
- Adding a backup option for /root/.kube/config

This version matching appears to be working as desired on three Raspberry Pi 3B+

The inventory file is breaking up my six node stack into two clusters. This will enable easier development.

* Lock docker version to currently installed version when it is installed (#44)

* Ignore failing deletion of swap (#46)

- Due to using hypriot, which doesn't have dphys-swapfile installed by
default, the current deletion process fails.  Adding `ignore_errors`
fixes this.

* reduce gpu memory (#48)

* update dashboard url (#47)

* K8S patch and other clean up items (#51)

* updated ansible configs to no longer use control paths as this failed on ubuntu 16.04 when deploying

* 50 - updated k8s version to latest release, updated docker, using flannel master currently as this is the only version that worked out of the box with k8s 1.13.1 - jh

* moved python apt dependency below apt-get update to allow for new installations to update cache prior installing, fixed reboot with logic from cleanup.yml

* removed apt-get update from kubeadm main since this is in common main and added environment var to stop apt from being angry - jh

* flannel at master now supports arm and amd64 k8s labels, as such we don't need to deal with this anymore.

* more updates for 1.14, removed gpu check since it's not longer working on my pi's and failing with a nonzero exit code.

* Altered apt syntax

Packages specified as an array in pkg rather than in with_items resolves "Invoking 'apt' only once while using a loop via squash_actions is deprecated" warning

* update_cache added

Resolves "No package matching 'kubelet' is available" error

* Brings develop in line with master and resolves the conflict. (#60)
