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 to all, this is a small issue I had the last days. Use a calculator in the terminal. I have been working and sometimes need to do an arithmetic operation so I decided to open calc (Ubuntu Calculator Default). But I was wondering, there has to be a way to use a calculator in the CLI. So after some search in the engine I found this question in Ask Ubuntu and tried several options.
I will only write about the best solution I found for my needs. In the question, you can find several solutions and probably you will find a different solution that will be best for you.

CALC (Arbitrary precision calculator)
Calc is an arbitrary precision arithmetic system that uses a C-like language. Calc is useful as a calculator, an algorithm prototyper and as a mathematical research tool. More importantly, calc provides one with a machine independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions.
If you want to install calc you can use the following command:
sudo apt-get install apcalc

ResponderEliminarYes, I saw it as an option, but using echo and then pipe, didn't like it to much.
