It's common when working with Kubernetes that we perform several queries to our cluster objects such as nodes, deployments, builds, pods and we don't always get the set of information we need, exposed by default via kubeclt get, having to resort in these cases to search the entire object bringing information beyond what is desired.
In the video below, we take a closer look at Spring Boot on how to change the default context path using the Java command. Let's get started!
Recently, while working on a project where we were using Python, I realized how easy the Java package mechanism makes it, to organize and reuse common classes and functions.
Due to my Java hangover, I organized the common classes and functions in a directory hierarchy like com.<company>.<project>.util. The util package contained a few classes for UUID creation as well as classes for date and time manipulation. After placing the files in the above-mentioned directory, I started developing the application as a micro-service. I placed the micro-service code in the directory com.<company>.<project>.<service>. While trying to use the date and time classes in the micro-service, I used the syntax from com.<company>.<project>.util.mydatetime import MyDateTime.
UFW, short for Uncomplicated Firewall, is basically a simplified firewall mechanism that is implemented upon IPtables itself, making it much easier to configure UFW than to configure IPtables. Therefore, it can be said that UFW is technically a program for managing a netfilter firewall which aims to provide an easy to use interface for the user.
Consider a situation where protocols like ssh, ftp, etc., which if left open for everyone and anyone to connect, might result in a massive security breach by the attackers or malicious users. Hence, this originated the need for a firewall. Firewall is useful to us in a way, that it allows us the remote access to the system but in a limited fashion. A simple example would be, firewall can allow certain ports to be left open to only a few IP addresses to limit security breach and also allowing connections to only a trusted device.
Git is one of the most important parts of the developer’s day-to-day work. So learning Git is a must for a newbie developer. In this article, you are going to learn the eight most important basic Git commands.
Below, I have listed down all the eight commands. Then, we will have a look at them one by one.
When it comes to locating files or directories on your system, the find command on Linux is unparalleled. It's simple to use, yet has a lot of different options that allow you to fine-tune your search for files.
Read on to see examples of how you can wield this command to find anything on your system. Every file is only a few keystrokes away once you know how to use the find command in Linux.
In this tutorial, we will cover the cURL command in Linux. Follow along as we guide you through the functions of this powerful utility with examples to help you understand everything it's capable of.
You can think of Linux runlevels as different "modes" that the operating system runs in. Each of these modes, or runlevels, has its own list of processes and services that are either turned on or off. From the time Linux boots up, it's always in some runlevel.
This runlevel may change as you continue to use your computer, depending on what kind of services the operating system needs access to.
The basic step when committing to open source projects is to fork the project. Then the process is easy you create your branch and you make a pull request. However, from time to time, you need to adjust your branch based on the latest changes.

This is how you sync your fork to the original one.
Today, we would like to introduce you to Trackman, the open-source, execute-commands-as-a-workflow tool. In this post, we take a closer look at what it is, why we need it, and how to best implement the tool. Let's get started.

Trackman is a command-line tool and Go library that runs multiple commands in a workflow. It supports parallel steps, step dependencies, async steps, and success checkers.
Today, I will show some more advanced Git operations using Visual Studio, without using the Git command line tool. This is the second part of the "Git Operation With Visual Studio" series. Please read the first article here. In the previous article, we have seen Git basic operations like creating repository and branch, cloning, commit, push changes, and more. Now, in this article, I will explain how to merge the branches and resolve the conflicts if any.
Update the local repository/branch to get changes from other members who have already made changes and merged. To update the code to keep it synced with others, there are three operations that come into the picture.
