This is to work around #1856 which can occur when kubelet
hostname and resolvable hostname (or cloud instance name)
do not match.

Eventually 2.3 support will be dropped, so this is
a temporary change.

Now adding unjoined members to existing etcd cluster
occurs one at a time so that the cluster does not
lose quorum.

* Refactor downloads to use download role directly

Also disable fact delegation so download delegate works acros OSes.

* clean up bools and ansible_os_family conditionals

Fixes #1129

* Update main.yml

Needs to set up resolv.conf before updating Yum cache otherwise no name resolution available (resolv.conf empty).

* Update main.yml

Removing trailing spaces

When downloading containers or files, use boolean
as a default value.

* Add possibility to insert more ip adresses in certificates

* Add newline at end of files

* Move supp ip parameters to k8s-cluster group file

* Add supplementary addresses in kubeadm master role

* Improve openssl indexes

This will allow running Kubespray when the user who runs it doesn't
have write permissions to the Kubespray dir, at least when not using
bastion.

Change KUBE_LOGGING to KUBE_LOGTOSTDERR, when installing kubelet
as host type.

* don't try to install this rpm on fedora atomic

* add docker 1.13.1 for fedora

* built-in docker unit file is sufficient, as tested on both fedora and centos atomic

Portmap allow to use hostPort with CNI plugins. Should fix #1675

* Disable basic and token auth by default

* Add recommended security params

* allow basic auth to fail in tests

* Enable TLS authentication for kubelet

* Restart kubelet on update in deployment-type host on update

* Update install_host.yml

* Update install_host.yml

* Update install_host.yml

* Change file used to check kubeadm upgrade method

Test for ca.crt instead of admin.conf because admin.conf
is created during normal deployment.

* more fixes for upgrade

In 1.8, the Node authorization mode should be listed first to
allow kubelet to access secrets. This seems to only impact
environments with cloudprovider enabled.

* Changre raw execution to use yum module

Changed raw exection to use yum module provided by Ansible.

* Replace ansible_ssh_* by ansible_*

Ansible 2.0 has deprecated the “ssh” from ansible_ssh_user, ansible_ssh_host, and ansible_ssh_port to become ansible_user, ansible_host, and ansible_port. If you are using a version of Ansible prior to 2.0, you should continue using the older style variables (ansible_ssh_*). These shorter variables are ignored, without warning, in older versions of Ansible.

I am not sure about the broader impact of this change. But I have seen on the requirements the version required is ansible>=2.4.0.

* add istio addon

* add addons to a ci job

This role only support Red Hat type distros and is not maintained
or used by many users. It should be removed because it creates
feature disparity between supported OSes and is not maintained.

This reverts commit 4209f1cb.

* Security fixes for etcd

* Use certs when querying etcd

* Clear admin kubeconfig when rotating certs

* Update main.yml

* Rename dns_server to dnsmasq_dns_server so that it includes role prefix
as the var name is generic and conflicts when integrating with existing ansible automation.
*  Enable selinux state to be configurable with new var preinstall_selinux_state
