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: Alwa...

Getting Docker Syntax In Gedit

I have been working with docker in the last days, and encounter the syntax issue with gedit. Just pure plain text. So make a small search and found an easy way for fixing this. I found Jasper J.F. van den Bosch repository in GitHub and found the solution for this simple problem. We need to download the docker.lang file, available here:  https://github.com/ilogue/docker.lang/blob/master/docker.lang After that, you go to the folder you save the file and do the following command. sudo mv docker.lang /usr/share/gtksourceview-3.0/language-specs/  If this doesn't work you can try the following: sudo mv docker.lang  ~/.local/share/gtksourceview-3.0/language-specs/ And that's all!

First of all, why should I used inventory if all over the internet they’re using the python scripts? Well, Ansible recommends it: Inventory plugins take advantage of the most recent updates to Ansible’s core code. We recommend plugins over scripts for dynamic inventory. You can write your own plugin to connect to additional dynamic inventory sources. https://docs.ansible.com/ansible/latest/user_guide/intro_dynamic_inventory.html The actual ansible guide is quite good, but there was a step that got me confused, probably my english isn’t so good and I didn’t understood it. We need to ena...
