Understanding Liveness, Readiness and Startup Probes in Kubernetes

 This is a small article about understanding the liveness, readiness and startup in kubernetes.  There's good explanation in the kubernetes documentation: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/ This video also explains well the process: https://www.youtube.com/watch?v=aTlQBofihJQ But I wanted to understand it in a practical way. So I have this demo: https://github.com/DiegoTc/guest-book-js-docker/tree/Running-App-Version-1 It's a simple application running on a kubernetes cluster. https://github.com/DiegoTc/guest-book-js-docker/blob/Running-App-Version-1/argo/deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: chat-ui spec: replicas: 1 revisionHistoryLimit: 3 selector: matchLabels: app: chat-ui template: metadata: labels: app: chat-ui spec: containers: - image: diegotc/guestbook:20230803-064434 imagePullPolicy: Always nam

Calc comes with a rich set of builtin mathematical and programmatic functions. If you want to install calc you can use th

Este 13 de Agosto del 2016 de mala suerte no ha tenido nada. Después de llevar una clase toda una mañana sobre manejar los conflictos en proyectos ágiles, sentarme y pasar a papel una idea que ya días estaba en la cabeza, la clasificación a semifinales de la selección olímpica me puse a pensar que nosotros los hondureños no somos personas ganadoras. Son pocos o nulos los triunfos a nivel internacional que tenemos, en deporte, ciencia, arte, etc. Pero hay algo que todo catracho tiene.
