This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.
Replaces use of --api-servers with --kubeconfig in Kubelet args across
the turnup scripts. In many cases this involves generating a kubeconfig
file for the Kubelet and placing it in the correct location on the node.
Local cluster creation using get-kube-local.sh is never finished.
The get-kube-local.sh monitors running_count of pods such as etcd,
master and kube-proxy, but these pods are created under the namespace
kube-system. Therefore kubectl can't find these pods then cluster
creation isn't completed.
The get-kube-local.sh should monitor created pods with option
"--namespace=kube-system".
Fix#42517
- default the release to the value of latest_release instead of
the string 'latest_release'
- use curl -O when retrieving kubectl to write output to disk instead
of to the screen
