                AWS Region Names
              
          
    Alternative naming schemes for AWS regions

Purpose

The intent is to define terse, standards-supported names for AWS regions.
Schemes


## kubectl-root-in-host-nopriv.pks.sh
#!/bin/sh
# Launch a Pod ab-using a hostPath mount to land on a Kubernetes node cluster as root
# without requiring `privileged: true`, in particular can abuse `DenyExecOnPrivileged`
# admission controller.
# Pod command in turn runs a privileged container using node's /var/run/docker.sock.
#
# Tweaked for PKS nodes, which run their docker stuff from different
# /var/vcap/... paths

    Problem

When scheduling actions to be carried out at a specific time there are a wealth of options. Each option suitable for a very different use case. The aim of this description is to present a use case with requirements and a solution to event scheduling.
Requirements


Scheduled events must be persisted
Events can be cancelled
Events can be rescheduled
Events are easily traceable
