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
Hi
Long time ago I haven't write in my blog.
The reason of this post is the fallowing. Last one I update mysql package. Mysteriously is stop working and getting a very nice error.
I report it as a bug. When I check the status, I saw it was a duplicate bug, and still no answer. So I decide to use askubuntu.com. I have never use askubuntu.com, only staroverflow, but just for searching never asking a question and never answering one question.
So at the end, I got my answer.
The solution goes the fallowing way
It was import to to the autoremove and autoclean, because I was having trouble with mysql package.
Want to read the complete answer.
Probably you will wonder, who cares if you solve a problem in askubuntu.com? Well I am just sharing how useful is the ubuntu community. And how they can help you. Many people prefer to stop using an application after one problem, instead of asking for help. If you are like that, you can give a chance to all the help ubuntu provides.
