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...

Not an Ubuntu Topic, but a Humanity Towards Others

Hi, I'm completely sorry to publish this article in the Ubuntu planet, as it's not related to any Ubuntu Topic.

I'm writing to you, requesting your help for one friend, coworker, Laura Cano. She has been indirectly involved in our Ubuntu Honduras Team. (She did the proof reading of our English articles).

She is currently fighting Acute Lymphoblastic Leukemia for the second time. In order to recover she needs a bone marrow transplant. Unfortunately, this procedure is not done in Honduras. Meaning she would have to go abroad to get the transplant done as well as looking for a donor, getting the proper medical examinations, and other expenses. She cannot afford any of these because she is still recovering economically from the first episode.

If you will like to help Laura please feel free to do so: https://www.gofundme.com/laura-cano-medical-fund or sharing this link to your friends will be of great help!

As I mention at the beginning, this is not an Ubuntu Topic, but as the meaning of Ubuntu is Humanity Toward Others, we can help any way to this cause.

Thanks
Diego

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!

Ansible using plugins for dynamic inventories

This is a small post about how to use inventory plugins in Ansible. If you are looking the script way I recommend to read this article: http://gloriasilveira.com/setting-up-ansible-for-aws-with-dynamic-inventory-ec2.html It explains really good this or you can watch this video: https://www.youtube.com/watch?v=LnbqO1kTPqE&t=6s But if you’re looking to use inventory this article can help you. 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...
