How to create a recursive promise chain. Source http://jsbin.com/qotabib/edit?js,console
// A recursive function returning Promise<number>
function recurseToZero(n) {
console.log('B. Entering recursive function for [' + n + '].');
// Once we hit zero, bail out of the recursion. The key to recursion is that
// it stops at some point, and the callstack can be "rolled" back up.
if (n === 0) {
// We could just return 0 but we do return Promise.resolve to have a consistent return type
return Promise.resolve(0);
}
// Start a NEW PROMISE CHAIN that will become the continuation of the parent

Playing with kubectl output

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no
exec > /tmp/${PROJECT_NAME}_archive.log 2>&1
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
if [ "true" == ${ALREADYINVOKED:-false} ]
then
echo "RECURSION: Detected, stopping"
else
export ALREADYINVOKED="true"
