We don't call klog.InitFlags yet, because that will cause a flag
redefinition error until we get everyone to stop using glog. That
will happen when we update to k8s 1.13.
We introduced some new heuristics in #3941 that meant we would access
private DNS names via the ELB's name, just as we do with gossip names.
But it's also possible to set up a VPN or DirectConnect and access a
private HostedZone directly, and in this case we don't want to use the
ELB DNS Name. We recognize this case because the ELB can be set to
Internal (and probably should be, for minimal attack surface!)
We'll probably have to introduce a field for this, but hopefully this
heuristic is sufficient to unblock the release.
Creating the keypair.yaml file if it does not exist.
If the Keypair is not found kops creates a new keyset file. We are
setting the Keyset Task Format to 'Keypair', which denotes that we do
not have a keypair.yaml file.
This commit enables upgrading from kops 1.8 -> 1.9 while upgrading an
existing cluster. Clusters built with kops 1.8 do not have the keypair
file, and these code changes allow the creation of that file.
