A periscopic view into pending Kubernetes pods

by React

Ekkremis

Optomize your Kubernetes pod lifecycle. Built with React Typescript with Electron/Node.js runtime.

Introduction

Some Kubernetes pods can’t be scheduled and get stuck in a pending phase of the pod lifecycle.

The status of pending pods has to be manually queried to proceed with resolving them, which slows down the deployment workflow.

This repository contains the code for Ekkremis: a prometheus-based alertmanager to resolve kubernetes pods pending issues. Ekkremis leverages prometheus data scraping and reports back when issues interfere with scheduling along with tailored solutions. Additionally, Ekkremis has an optional lifecycle dashboard where DevOps engineers will find a consolidated view of pod metrics by state. Solutions provided by Ekkremis (greek for pending) increases Kubernetes deployment efficiency by providing updates on pending and other unhealthy pods to get them up and running faster.

Requirements

  • Prometheus (can run demo without)
  • npm (web view only)
  • yarn (web or electron app)

Features

A few of the things you can do with Ekkremis:

  • Reduce manual queries to find unhealthy or pending pods
  • Receive alerts by email or slack when your pods are stuck in pending
  • Implement tailored solutions suggested by Ekkremis to get your pods up and running

Optional Ekkremis Lifecycle Dashboard.

Lots of great screenshots coming!

Alerts Setup

Dashboard Build Process

Initial Setup

  • Clone or download the repo
  • npm install to install dependencies

If running Ekkremis on Web App

  • npm run build to create a build folder

If running Ekkremis on Electron App

  • install yarn if you don’t already have it (required for the following steps)
  • npm run postinstall to install electron-specific dependencies
  • npm run electron:build to build the Electron app for current platform and current architecture using default target

Once running the app

  • Add your prometheus metrics endpoint for Kubernetes pods to the metrics input (Ekkremis defaults to http://localhost:9090)
  • Navigate between pod status metric displays through the navigation bar on the left
  • Gain more information about individual unhealthy or pending pods by selecting the ‘error’ and ‘charts’ buttons
  • Implement solutions suggested in Ekkremis for pending pods

Running the DEMO with Mock Data

  • Add this mock promethus endpoint to the metrics input
