Cleanup k8s script noise with a verbosity concept
Fixes https://github.com/kubernetes/kubernetes/issues/30109
The KUBE_VERBOSE environment variable sets the verbosity level to
use. Log messages can specify a verbosity by setting the V
variable. e.g.
V=2 kube::log::info foo bar
Would only print "foo bar" if $KUBE_VERBOSE >= 2.
Examples:
Default verbosity (1 for make commands):
```
$ make kubelet

AWS/GCE: Rework use of master name
* Add a pillar for `hostname` (because even if there's a good Salt function for it, I don't trust it to return the short hostname)
* Move `INITIAL_ETCD_CLUSTER` to just the GCE turn-up
* Remove `master_name`, which isn't needed
The KUBE_VERBOSE environment variable sets the verbosity level to
use. Log messages can specify a verbosity by setting the V
variable. e.g.
V=2 kube::log::info foo bar
Would only print "foo bar" if $KUBE_VERBOSE >= 2.

In cluster scripts correct gcloud list arg from '--zone' to '--zones'
I started getting these messages when doing `kube-up` and similar operations:
WARNING: Abbreviated flag [--zone] will be disabled in release 132.0.0, use the full name [--zones].
This PR corrects the flag where used.
Note there are many uses of `--zone` on commands like `gcloud instances describe` which are still correct - those commands do not accept multiple zones.

GKE test-build-release: Actually do the build.
Multiple devs (myself included!) have experienced frustration with the fact that if `KUBERNETES_PROVIDER=gke` then `hack/e2e.go --build` doesn't actually do a build.
Are we actually relying on this behavior anywhere?

[Garbage Collector] add e2e tests again
#27151 is reverted because gke didn't start correctly after it's merged (https://github.com/kubernetes/kubernetes/pull/27151#issuecomment-233030686).
The possible problem is the `unbound variable`, which is fixed in the second commit of this PR. However, I cannot verify if the PR will fail the gke suite since I don't have the environment to run that suite.

cluster/images/hyperkube: re-add hyperkube busybox style symlinks
Originally symlinks were added with a `--make-symlinks` command discussed in https://github.com/kubernetes/kubernetes/issues/24510 and implemented in https://github.com/kubernetes/kubernetes/pull/24511.
It was backed out in https://github.com/kubernetes/kubernetes/pull/25693 because go binaries don't run in qemu and this breaks cross-building the Dockerfile for arm. In this case, due to running `hyperkube --make-symlinks`.
Lets just add the symlinks manually until the upstream bug is fixed (qemu).

Bump exechealthz image
With the new image at least if we observe an exec container taking more ram than it should (like the oom situation, which shouldn't happen today because of the increased limits), we can kubectl exec and check the pprof endpoints.

Add load balancer in front of apiserver in HA master setup
The first commit is just https://github.com/kubernetes/kubernetes/pull/29201 and has been already LGTMed.
Second commit has some small fixes:
1. Precompute REGION variable in config
2. Add timeout for waiting for loadbalancer
3. Fix kube-down so that it doesn't delete some resources if there are still masters/nodes in other zones
Second commit also fixes bug in https://github.com/kubernetes/kubernetes/pull/29201 where variable `REGION` was unset in `kube-down` when deleting master IP. The bug caused leaking of IP addresses.

resolves#20971 by using the options provided by ssh.
Native ssh compression has existed for years, and the server is free to disregard the setting, so this should be safe.
With things like the kube binaries I see about a 2x speed increase.

kube-up: install new Docker pre-requisite (libltdl7) when not in image
Docker now has a dependency on libltdl7; we have to specify it manually
if we are installing docker using dpkg (vs using apt-get or similar,
which would pull it in automatically)
Fixes#28644
This allows us to start building real dependencies into Makefile.
Leave old hack/* scripts in place but advise to use 'make'. There are a few
rules that call things like 'go run' or 'build/*' that I left as-is for now.

Check existence of kubernetes dir for get-kube.sh
[]()
There are a lot of references to https://get.k8s.io/ over the internet.
Most of such references do not describe KUBERNETES_SKIP_DOWNLOAD env variable
and newbies can get into a situation described below:
- execute `wget -q -O - https://get.k8s.io | bash`
- receive a failure due too missed packages or some configs
- fix the issue
- try again `wget -q -O - https://get.k8s.io | bash`
In this case, get-kube.sh will not check that kubernetes directory already
exist and repeat download again.
Lets make get-kube.sh more user-friendly and check existence of kubernetes dir

Enhance kubedns pod health checks to cover kubedns container
The existing health check hits port 53, the dnsmasq container, with the same domain name every time. Since dnsmasq looks up and caches results from the kubedns container, running on port 10053, the health check is not covering the kubedns container after the first query (and once every TTL expiration).
This PR enhances the health check to directly hit port 10053 (kubedns) in addition to port 53.

Substitute federation_domain_map parameter with its value in node bootstrap scripts.
This PR also removes the substitution code we added to the build scripts.
**Release Note**
```release-note
If you use one of the kube-dns replication controller manifest in `cluster/saltbase/salt/kube-dns`, i.e. `cluster/saltbase/salt/kube-dns/{skydns-rc.yaml.base,skydns-rc.yaml.in}`, either substitute one of `__PILLAR__FEDERATIONS__DOMAIN__MAP__` or `{{ pillar['federations_domain_map'] }}` with the corresponding federation name to domain name value or remove them if you do not support cluster federation at this time. If you plan to substitute the parameter with its value, here is an example for `{{ pillar['federations_domain_map'] }`
pillar['federations_domain_map'] = "- --federations=myfederation=federation.test"
where `myfederation` is the name of the federation and `federation.test` is the domain name registered for the federation.
```

Enable setting up Kubernetes cluster in Ubuntu on Azure
Implement basic cloud provider functionality to deploy Kubernetes on
Azure. SaltStack is used to deploy Kubernetes on top of Ubuntu
virtual machines. OpenVpn provides network connectivity. For
kubelet authentication, we use basic authentication (username and
password). The scripts use the legacy Azure Service Management APIs.
We have set up a nightly test job in our Jenkins server for federated
testing to run the e2e test suite on Azure. With the cloud provider
scripts in this commit, 14 e2e test cases pass in this environment.
We plan to implement additional Azure functionality to support more
test cases.

Tracked addition of federation, sed support in kube DNS
[]()
The kube DNS app recently gained support for federation (whatever that
is), including a new Salt parameter. This broke the deployAddons.sh script for cluster ubuntu. The DNS app also gained alternate
templates, intended to be friendly to `sed`. Fortunately, those do
not demand a federation parameter.
This PR fixes up the ` cluster/ubuntu/deployAddons.sh` script to track those changes, by switching to the `sed`-friendly templates.

mount instanceid file from config drive when using openstack cloud provider
fix https://github.com/kubernetes/kubernetes/issues/23191, the instanceid file is read however we do not mount it as a volume, and it would cause the cloud provider contacts the metadata server, in some cases, the metadata server is not able to serve, then the cloud provider would fail to initialize, we should avoid that.
