currently the pgrep check does not allow any etcd process to exist
other than the one we intend to start in our scripts. All we need
to know is if the port is free. So let us use netstat to check
if anyone is using that port. We don't really need to know if there
is another instance of etcd is running or not.
Prior this change, etcd wasn't cleaned up on my machine that lead to
orphaned etcd process after the update-swagger-spec.sh failed.
This change also adds additional improvements:
- don't kill/wait/rm when argument is empty.
- use kube::util::trap_add.
third_party/etcd isn't guaranteed to be present, this was causing
the script to fail prior to printing out the error message about
version mismatch
fixes#41989
from etcd.sh split the start process into validate fucntion + start function so that the validate piece can be reused elsewhere. the up-cluster script has been changed to remove duplicate docker logic to the one used in buid-tools/common.sh and the validate etcd function is now used here.
moved docker daemon check function to util.sh and made function name changes and upstream changes.

Fix support for DNS in local-up-cluster.sh
[]()
The default appears to be gce now, so this tries to spawn a service in
gce... not the desired outcome for a local test setup.
We also need to sync the kubectl config in the script with the instructions for users, since if people don't test with DNS enabled, it bitrots (which this aims to fix).
To test manually, run something like
```
sudo KUBE_ENABLE_CLUSTER_DNS=true API_HOST_IP=0.0.0.0 ./hack/local-up-cluster.sh
```
The API_HOST_IP=0.0.0.0 is required, otherwise the master is not contactable by kubedns, and the dns pod will fail readychecking on the healthz pod.

Prevent SIGPIPE errors causing the version check line to fail
The way we use pipe in hack/lib/etcd.sh when processing the version command can lead to
141 failues on some systems. Using a prefix of tail can prevent this.
Fixes#38109
- Fix unbound variables in hack/local-up-cluster.sh
- explicitly set KUBERNETES_PROVIDER in local-up-cluster.
The default appears to be gce now, so this tries to spawn a service
in gce... not the desired outcome for a local test setup.
- Remove stale creation of kube-system: the kube-system namespace is
built in these days.
- Pickup third party etcd automatically.
- Retab hack/local-up-cluster.sh for consistency
- Update hack-local-up's internal credentials to match the user
instructions we give (which work).
- Note the CA root requirement in local-up-cluster
- Fix a dangling comment in local-up-cluster
To test manually, run something like:
```sudo KUBE_ENABLE_CLUSTER_DNS+true API_HOST_IP=0.0.0.0
./hack/local-up-cluster.sh```
The API_HOST_IP=0.0.0.0 is required otherwise kubedns cannot contact
the master and the dns pod will fail readychecking on the healthz
container.

Get install-etcd.sh to work on OSX
Check the platform before we download the etcd binary. On OSX, save
the zip file, unzip it and link the directory with the correct
name.
Fixes#26041
* Rewrite a bunch of the hack/ directory with modular reusable bash libraries.
* Have 'build/*' build on 'hack/*'. The stuff in build now just runs hack/* in a docker container.
* Use a docker data container to enable faster incremental builds.
* Standardize output to _output/{local,dockerized}/bin/OS/ARCH/*. This regularized placement makes cross compilation work.
* Move travis specific scripts under hack/travis
With new dockerized incremental builds, I can do a no-op `make quick-release` in ~30s. This is a significant improvement.
