Greg Althaus 3f0c13af8a Make kubelet_load_modules always present but false.
Update code and docs for that assumption.
2017-02-09 10:25:44 -06:00
Greg Althaus fcd78eb1f7 Due to the nsenter and other reworks, it appears that
kubelet lost the ability to load kernel modules.  This
puts that back by adding the lib/modules mount to kubelet.

The new variable kubelet_load_modules can be set to true
to enable this item.  It is OFF by default.

Matthew Mosesohn 3c713a3f53 Fix upgrade for all daemonset type resources
Daemonsets cannot be simply upgraded through a single API call,
regardless of any kubectl documentation. The resource must be
purged and then recreated in order to make any changes.

Alexander Block 89e570493a Also add the system nameservers to upstream servers in dnsmasq
Also make no-resolv unconditional again. Otherwise, we may end up in
a resolver loop. The resolver loop was the cause for the piling up
parallel queries.

Artem Panchenko 1418fb394b Explicitly set config path for DNSMasq
When DNSMasq is configured to read its settings
from a folder ('-7' or '--conf-dir' option) it only
checks that the directory exists and doesn't fail if
it's empty. It could lead to a situation when DNSMasq
is running and handles requests, but not properly
configured, so some of queries can't be resolved.

Aleksandr Didenko f05aaeb329 Fix calico-rr peering with k8s masters
Calico-rr is broken for deployments with separate k8s-master and
k8s-node roles. In order to fix it we should peer k8s-cluster
nodes with calico-rr, not just k8s-node. The same for peering
with routers.

Sergii Golovatiuk 61d05dea58 Allow to specify number of concurrent DNS queries
ndots creates overhead as every pod creates 5 concurrent connections
that are forwarded to sky dns. Under some circumstances dnsmasq may
prevent forwarding traffic with "Maximum number of concurrent DNS
queries reached" in the logs.

This patch allows to configure the number of concurrent forwarded DNS
queries "dns-forward-max" as well as "cache-size" leaving the default
values as they were before.

Greg Althaus 6c69da1573 This PR adds/or modifies a few tasks to allow for the playbook to
be run by limit on each node without regard for order.

The changes make sure that all of the directories needed to do
certificate management are on the master[0] or etcd[0] node regardless
of when the playbook gets run on each node.  This allows for separate
ansible playbook runs in parallel that don't have to be synchronized.

Greg Althaus 95bf380d07 If the inventory name of the host exceeds 63 characters,
the openssl tools will fail to create signing requests because
the CN is too long.  This is mainly a problem when FQDNs are used
in the inventory file.

THis will truncate the hostname for the CN field only at the
first dot.  This should handle the issue for most cases.
