The value cannot be determined properly via local facts, so
checking k8s api is the most reliable way to look up what hostname
is used when using a cloudprovider.
This follows pull request #1677, adding the cgroup-driver
autodetection also for kubeadm way of deploying.
Info about this and the possibility to override is added to the docs.
Red Hat family platforms run docker daemon with `--exec-opt
native.cgroupdriver=systemd`. When kubespray tried to start kubelet
service, it failed with:
Error: failed to run Kubelet: failed to create kubelet: misconfiguration: kubelet cgroup driver: "cgroupfs" is different from docker cgroup driver: "systemd"
Setting kubelet's cgroup driver to the correct value for the platform
fixes this issue. The code utilizes autodetection of docker's cgroup
driver, as different RPMs for the same distro may vary in that regard.
New files: /etc/kubernetes/admin.conf
/root/.kube/config
$GITDIR/artifacts/{kubectl,admin.conf}
Optional method to download kubectl and admin.conf if
kubeconfig_lcoalhost is set to true (default false)
* kubeadm support
* move k8s master to a subtask
* disable k8s secrets when using kubeadm
* fix etcd cert serial var
* move simple auth users to master role
* make a kubeadm-specific env file for kubelet
* add non-ha CI job
* change ci boolean vars to json format
* fixup
* Update create-gce.yml
* Update create-gce.yml
* Update create-gce.yml
* Fix netchecker update side effect
kubectl apply should only be used on resources created
with kubectl apply. To workaround this, we should apply
the old manifest before upgrading it.
* Update 030_check-network.yml
* Add option for fact cache expiry
By adding the `fact_caching_timeout` we avoid having really stale/invalid data ending up in there.
Leaving commented out by default, for backwards compatibility, but nice to have there.
* Enabled cache-expiry by default
Set to 2 hours and modified comment to reflect change
* Add comment line and documentation for bastion host usage
* Take out unneeded sudo parm
* Remove blank lines
* revert changes
* take out disabling of strict host checking
This sets br_netfilter and net.bridge.bridge-nf-call-iptables sysctl from a single play before kube-proxy is first ran instead of from the flannel and weave network_plugin roles after kube-proxy is started
the uploads.yml playbook was broken with checksum mismatch errors in
various kubespray commits, for example, 3bfad5ca73
which updated the version from 3.0.6 to 3.0.17 without updating the
corresponding checksums.
