Smaine Kahlouch d6f206b5fd Merge pull request #561 from kubespray/rsync_certs
Use tar+register instead of copy/slurp for distributing tokens and certs
2016-10-27 10:52:41 +02:00
Matthew Mosesohn c7b00caeaa Use tar+register instead of copy/slurp for distributing tokens and certs
Related bug: https://github.com/ansible/ansible/issues/15405

Uses tar and register because synchronize module cannot sudo on the
remote side correctly and copy is too slow.

This patch dramatically cuts down the number of tasks to process
for cert synchronization.

Chad Swenson a5137affeb Hostname alias fixes
Change the kubelet --hostname-override flag to use the ansible_hostname variable which should be more consistent with the value required by cloud providers

Add ansible_hostname alias to /etc/hosts when it is different from inventory_hostname to overcome node name limitations see https://github.com/kubernetes/kubernetes/issues/22770

Artem Roma 3919d666c1 Add possibility to enable network policy via Calico network controller
The requirements for network policy feature are described here [1]. In
order to enable it, appropriate configuration must be provided to the CNI
plug in and Calico policy controller must be set up. Beside that
corresponding extensions needed to be enabled in k8s API.

Now to turn on the feature user can define `enable_network_policy`
customization variable for Ansible.

Bogdan Dobrelya 5fd43b7cf0 Allow subdomains of dns_domain and fix kubelet restarts
* Add a var for ndots (default 5) and put it hosts' /etc/resolv.conf.
* Poke kube dns container image to v1.7
* In order to apply changes to kubelet, notify it to
be restarted on changes made to /etc/resolv.conf. Ignore errors as the kubelet
may yet to be present up to the moment of the notification being processed.
* Remove unnecessary kubelet restart for master role as the node role ensures
it is up and running. Notify master static pods waiters for apiserver,
scheduler, controller-manager instead.

Bogdan Dobrelya 82ee60fe8b Make dnsmasq daemon set optional
Change additional dnsmasq opts:
- Adjust caching size and TTL
- Disable resolve conf to not create loops
- Change dnsPolicy to default (similarly to kubedns's dnsmasq). The
  ClusterFirst should not be used to not create loops
- Disable negative NXDOMAIN replies to be cached
- Make its very installation as optional step (enabled by default).
  If you don't want more than 3 DNS servers, including 1 for K8s, disable
  it.
- Add docs and a drawing to clarify DNS setup.
- Fix stdout logs for dnsmasq/kubedns app configs
- Add missed notifies to resolvconf -u handler
- Fix idempotency of resolvconf head file changes
