Our remedy system looks like:

Detect permanent node problems and set Node Conditions using the Node Problem Detector.
Configure Draino to cordon and drain nodes when they exhibit the NPD's KernelDeadlock condition, or a variant of KernelDeadlock we call VolumeTaskHung.
Let the Cluster Autoscaler scale down underutilised nodes, including the nodes Draino has drained.

Note: Draino will log nothing, and export no metrics until it actually drains a node.

Once the Descheduler supports descheduling pods based on taints, Draino could be replaced by the Descheduler running in combination with the scheduler's TaintNodesByCondition functionality. See kubernetes-sigs/descheduler#131

Post Google Sheets form entries to Slack

By using Google Form's script editor, you can call Slack webhooks when form submissions are made. You can use this script to do things like creating a live feedback form for taking questions from an audience or notifying your team when someone signs up for an event.

Setup

First, be sure you're collecting the email address in the form:

React component ui kits that are popular NPM Charts

Install Golang (skip if already done)

If you don't have golang installed, you need to do that and export GOPATH

if [[ ! $(go version 2>/dev/null) ]]
then
  brew install go --cross-compile-common
fi

export GOPATH=${GOPATH:-$HOME/go}
mkdir -p "$GOPATH"

A Webhook, in simple terms, is a user-defined HTTP callback. It is a mechanism for the system to notify you about an event. In our case, we need to send messages to a particular channel in slack. Slack calls in Incoming Webhook. It is a mechanism to send messages to your Slack Channel from external sources. These external sources could be any application or service that is capable of sending a JSON payload over HTTP into a Slack Channel. Each Channel will be identified by a unique Incoming Webhook URL to which you can post the message from outside. This configuration is done via the Integrations for your channel.

Steps to create a incoming webhook in Slack:

Naviagte to the Incoming Webhook URL. Click the hyper link incoming webhook integration below the heading Incoming Webhooks.
You will be asked to enter your team URL, followed by your slack credentials.
Once you have completed the above step, you will see the wizard kind of webpage to
