ensure-kube-token is not needed anymore because
the token passed in kube-env.
In the up case it is set, in the push case it is an empty string
but not used.
Allow unset KUBELET_TOKEN (for push case).
Fix comment.
- Configure the apiserver to listen securely on 443 instead of 6443.
- Configure the kubelet to connect to 443 instead of 6443.
- Update documentation to refer to bearer tokens instead of basic auth.
Generates the new token on AWS, GCE, Vagrant.
Renames instance metadata from "kube-token" to "kubelet-token".
(Is this okay for GKE?)
Having separate tokens for kubelet and kube-proxy permits
using principle of least privilege, makes it easy to
rate limit the clients separately, allows annotation
of apiserver logs with the client identity at a finer grain
than just source-ip.
* Fixes an issue where salt-minion would actually come up after reboot
(upstart is horrible obnoxious)
* Caches .deb downloads
* Handles PD remount on reboot correctly
* Notes a future optimization
Fixes#5666
This is needed when we upgrade (and useful when you're trying to
change the startup script for reboots).
Along the way: allow add-instance-metadata[-from-file] to take a
variable number of KVs.
Address #6075: Shoot the master VM while saving the master-pd. This
takes a couple of minor changes to configure-vm.sh, some of which also
would be necessary for reboot. In particular, I changed it so that the
kube-token instance metadata is no longer required after inception;
instead, we mount the master-pd and see if we've already created the
known tokens file before blocking on the instance metadata.
Also partially addresses #6099 in bash by refactoring the kube-push
path.
These secrets will be used in subsequent PRs by:
scheduler, controller-manager, monitoring services,
logging services, and skydns.
Each of these services will then be able to stop using kubernetes-ro
or host networking.
It looks like api_servers finally won this battle. Kill off the
last remaining places passing it, but allow the kubelet Salt to
accept apiservers for a period of time.
(This was bothering my OCD.)
