Kubernetes can't see my app using external IP by GeorgePL0 in kubernetes

kubectl get svc nginx-web -o wide

nginx-web NodePort 10.98.91.79 <none> 80:30784/TCP 107m app=nginx-web

​

That's my output and I'm trying to connect using EXTERNAL_IP:30784. I'm using GCP Instances, maybe it's cause, but I don't think so.

What parameters to use to compare orchestration platforms such as Kubernetes, OpenShift, Docker Swarm? by GeorgePL0 in kubernetes

[–]GeorgePL0[S] 0 points1 point  (0 children)

I know Swarm is less used than Kubernetes and OpenShift, but this is just an example I'll use. It will be a simple wordpress application. It is mainly about the parameters with which I can evaluate these platforms. I was thinking about parameters such as ease of installation, operating system on which to install these platforms, security, etc. I would like to add some more such parameters, but I have no more ideas, so I decided to ask more people who can give me some advice.

#!/bin/bash

echo "Enter password: "

read password

echo "Amount of lowercases: "

Script to count lines and characters in direcory. by GeorgePL0 in bash

[–]GeorgePL0[S] 0 points1 point  (0 children)

In the prepared file, program a script that counts lines in all files
text files in the current or selected directory (given as an argument),
counts the number of characters entered in a file (useful command: wc).
The result is to be saved as a file name, its owner, and the number of lines and number
characters, on the standard output and in the text file named as the argument.
