Kubernetes Submit Queue de0643106c Merge pull request #57756 from mborsz/exec-manifest
Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>.

Add 'exec' in all saltbase manifests using '/bin/sh -c'.

Right now, if docker sends SIGTERM, /bin/sh doesn't pass it to
underlying process, which breaks graceful process shutdown.

Changing '/bin/sh -c CMD > /var/log/FILE.log' pattern to '/bin/sh -c
exec CMD > /var/log/FILE.log' still allows to redirect output to log
file, but also passes all signals to CMD process.

SaltStack configuration

This is the root of the SaltStack configuration for Kubernetes. A high level overview for the Kubernetes SaltStack configuration can be found in the docs tree.

This SaltStack configuration currently applies to default configurations for Debian-on-GCE, Fedora-on-Vagrant, Ubuntu-on-AWS and Ubuntu-on-Azure. (That doesn't mean it can't be made to apply to an arbitrary configuration, but those are only the in-tree OS/IaaS combinations supported today.) As you peruse the configuration, these are shorthanded as gce, vagrant, aws, azure-legacy in grains.cloud; the documentation in this tree uses this same shorthand for convenience.
