format-disks used to run with non-strict bash semantics, but this changed in
1.2 as we now merge it into the GCE script, so pipefail and errexit are both
set.
However, the way we list the ephemeral disks, by piping to grep, would cause an
exit code of 2 if there were no ephemeral disks.
Tolerate failure here by add `|| true`. The metadata service call is unlikely
to fail, so we continue to ignore that possibility.
Otherwise we risk services coming up on the master before the backing
volume is ready.
If we then see the master-pd is already mounted, don't try to remount
it.
Issue #21155
If the ephemeral volume is present and mounted, don't try to reinitialize
them.
Don't block the boot if the ephemeral volume is corrupt / missing -
this enables us to cope with a stop/start & presumably also corruption.
In this case, we'll reformat the ephemeral storage.
Fix#21157
This is so we have the same behaviour as on GCE.
This also lets us change the bootstrap script or the config, which is
nice. Instance data is immutable on AWS once it is booted.
Fix#21150
Remove a comment that disabled the redirection of output destined for
`/etc/salt/minion.d/grains.conf`. Must have been a commented added to
debug the generation of the line, to view it on `STDOUT`.
Addresses #15968
This patch removes KUBE_ENABLE_EXPERIMENTAL_API and similar calls in
favor of specifying desired features in KUBE_RUNTIME_CONFIG. Changes
have also been made to e2e scripts to re-enable using
KUBE_RUNTIME_CONFIG rather than EXPERIMENTAL_API env vars.
This also introduces KUBE_ENABLE_DAEMONSETS and KUBE_ENABLE_DEPLOYMENTS.

When KUBE_E2E_STORAGE_TEST_ENVIRONMENT is set to 'true', kube-up.sh script
will:
- Install the right packages for all storage volumes.
- Use devicemapper as docker storage backend. 'aufs', the default one on
Debian, does not support extended attibutes required by Ceph RBD and Gluster
server containers.
Tested on GCE and Vagrant, e2e tests for storage volumes passes without any
additional configuration.
Fixes AWS ubuntu deployment due to extra-$(uname) vs extra-virtual
package being installed. See issue #14162

We need this for some tests; not all the options are fully plumbed in,
but should enable experimental/v1alpha1, as needed for jobs tests.
In particular, ENABLE_NODE_AUTOSCALER is not yet actually implemented.
OpenContrail is an open-source based networking software which provides virtualization support for the cloud.
This change-set adds ability to install and provision opencontrail software for networking in kubernetes based cloud environment.
There are basically 3 components
o kube-network-manager -- plugin between contrail components and kubernets components
o provision_master.sh -- OpenContrail software installer and provisioner in master node
o provision_minion.sh -- OpenContrail software installer and provisioner in minion node(s)
These are driven via salt configuration files
One can provision opencontrail by just setting "export NETWORK_PROVIDER=opencontrail"
Optionally, OPENCONTRAIL_TAG, and OPENCONTRAIL_KUBERNETES_TAG can be used to
specify opencontrail and contrail-kubernetes software versions to install and provision.
Public-IP Subnet provided by contrail can be configured via OPENCONTRAIL_PUBLIC_SUBNET
environment variable
At this moment, plan is to add support for aws, gce and vagrant based platforms

We were splitting the aufs storage into docker & kubernetes areas, but
the kubernetes area was filling up very quickly because empty volumes
went on there, and I had originally not sized it big enough for that.
Instead, create one volume for both so they can share space freely. We
can't do this for devicemapper, but that configuration seems to be
deprecated by Docker anyway.
GCE does this in its per-provider scripts; this does the same for AWS and lets
other providers do the same; I believe kube2sky requires 10.0.0.1 as a SAN.
If we're going to have a persistent disk on /mnt/master-pd, it seems risky
sometimes to have /mnt be a mounted volume.
A new consistent approach: we mount volumes under /mnt/<name>.
For parity with GCE, we really want to support aufs.
But we previously supported btrfs, so we want to expose that.
Most of the work here is required for aufs, and we let advanced users choose
devicemapper/btrfs if they have a setup that works for those configurations.
