Reduce CI test matrix
2016-11-30 10:43:43 +01:00
Bogdan Dobrelya a2331fec55 Reduce CI test matrix
Reduce the test cases from 15 to 9, bearing in mind that:
* Disable weave/coreos gate unless its deployment fixed
* If debian/centos7 fails with net plugin X, ubuntu-xenial/rhel-7 will
  likely fail as well
* Canal also covers the flannel plugin deployment, but keep at least one
  of the flannel plugin deployment, unless it's superseded and removed.
* Keep at least one of each OS/plugin family to be tested in the separate
  nodes layout
* Keep at least one of each OS family to be tested against each of the
  plugin types in default nodes layout
* Rebalance GCE regions for instances, replace asia to eu/us as they
  are the longest running jobs.

2016-11-28 15:26:30 +01:00
Bogdan Dobrelya b7692fad09 Add advanced net check for DNS K8s app
* Add an option to deploy K8s app to test e2e network connectivity
  and cluster DNS resolve via Kubedns for nethost/simple pods
  (defaults to false).
* Parametrize existing k8s apps templates with kube_namespace and
  kube_config_dir instead of hardcode.
* For CoreOS, ensure nameservers from inventory to be put in the
  first place to allow hostnet pods connectivity via short names
  or FQDN and hostnet agents to pass as well, if netchecker
  deployed.

Bogdan Dobrelya aa447585c4 Fix download dnsmasq image dependency on docker
When download_run_once with download_localhost is used, docker is
expected to be running on the delegate localhost. That may be not
the case for a non localhost delegate, which is the kube-master
otherwise. Then the dnsmasq role, had it been invoked early before
deployment starts, would fail because of the missing docker dependency.

* Fix that dependency on docker and do not pre download dnsmasq image
  for the dnsmasq role, if download_localhost is disabled.
* Remove become: false for docker CLI invocation because that's not
  the common pattern to allow users access docker CLI w/o sudo.
* Fix opt bin path hack for localhost delegate to ignore errors when
  it fails with "sudo password required" otherwise.
* Describe download_run_once with download_localhost use case in docs
  as well.

2016-11-24 10:42:38 +01:00
Bogdan Dobrelya d208896c46 Ensure /etc/resolv.conf content for CoreOS
Use cloud-init config to replace /etc/resolv.conf with the
content for kubelet to properly configure hostnet pods.

Do not use systemd-resolved yet, see
https://coreos.com/os/docs/latest/configuring-dns.html
"Only nss-aware applications can take advantage of the
systemd-resolved cache. Notably, this means that statically
linked Go programs and programs running within Docker/rkt
will use /etc/resolv.conf only, and will not use the
systemd-resolve cache."

Bogdan Dobrelya d890d2f277 Fix nginx container download for download_run_once mode
W/o this patch, the "Download containers" task may be skipped
when running on the delegate node due to wrong "when" confition.
Then it fails to upload nginx image to the nodes as well.

Fix download nginx dependency so it always can be pushed to
nodes when download_run_once is enabled.

Aleksandr Didenko db03f17486 Set defaults for ansible_ssh_user
When setting permission for containers download/upload dir we're
using `ansible_ssh_user`. But if playbook is executed without
user being explicitly set `ansible_ssh_user` may be undefined.
In such situations dir ownership will default to `ansible_user_id`

Closes: #644

Bogdan Dobrelya dff78f616e Allow pre-downloaded images to be used effectively
According to http://kubernetes.io/docs/user-guide/images/ :
By default, the kubelet will try to pull each image from the
specified registry. However, if the imagePullPolicy property
of the container is set to IfNotPresent or Never, then a local\
image is used (preferentially or exclusively, respectively).

Use IfNotPresent value to allow images prepared by the download
role dependencies to be effectively used by kubelet without pull
errors resulting apps to stay blocked in PullBackOff/Error state
even when there are images on the localhost exist.

Dan Bode cb84b93930 Decouple etcd/k8s-cluster roles in ec2 terraform
Currently, the terraform script in contrib
adds etcd role as a child of k8s-cluster in
its generated inventory file.

This is problematic when the etcd role is
deployed on separate nodes from the k8s master
and nodes. In this case, this leads to failures
of the k8s node since the PKI certs required for
that role have not been propogated.

Dan Bode ff675d40f9 Ensure that etcd health checks always pass
in the etcd handler, the reload etcd action
was called after ansible waits for etcd to be
up, this means that the health checks which are
called immediately after fail (resulting in the etcd
role always failing and never finishing)

This patch changes the order to move the 'wait for etcd
up' resource after the 'reload etcd resource', ensuring that
the service is up before the health check is called.

* For Travis CI, enable docker images caching and run Travis
  workers with sudo enabled as a dependency
* For Travis CI, deploy with download_localhost and download_run_once
  enabled to shourten dev path drastically.
* Add compression for saved container images. Defaults to 'best'.

Aleksandr Didenko 3e687bbe9a Fix download_run_once for containers
Add one more step (task) to containers download/upload sequence -
copy saved .tar containers to ansible host (delegate_to: localhost).

Then upload images to target nodes. It uses synchronize module so
if ansible host (localhost) is the same host as kube-master[0] then
new task causes no issues and the copy to localhost process is
basically skipped.
