Minikube is software that allows users to run a Kubernetes cluster of just a single node. It is rather fast to set up and makes for a perfect testing environment for developers to see how their containerized application will run on Kubernetes. It is not meant for production, but rather to test applications and deployment settings to see how they fare before sending them to a production environment.
How to use helm package manager for Kubernetes
Helm is the package manager for Kubernetes, akin to
apt on Debian and Ubuntu, or the pip package manager for Python. It allows administrators to install and manage applications in their Kubernetes cluster with ease. In this tutorial, we will explore how to use the Helm package manager for Kubernetes on a Linux system.
How to Install Kubernetes on All Linux Distros
Kubernetes is container orchestration software that allows us to deploy, manage, and scale containerized applications across any number of node systems. It is a powerful and open source technology which makes it far more efficient to run applications at scale, and supersedes the traditional way of running applications directly on the operating system or in a virtual machine. A Kubernetes cluster also introduces self healing, load balancing, and a way to manage hundreds or thousands of containerized application from a single command prompt.
How to use disk quota on Linux with examples
Implementing a disk quota will prevent users or groups from using too much storage space on a Linux system. This is very useful on systems such as file servers that allow many users to connect and store data, as it ensures that no particular user can utilize an unexpected amount of storage and interrupt storage or processes on the server by making it run out of disk space. Linux administrators should always put a quota on the maximum storage usage for users, as well as other user environment limits like max number of processes and open files.
Linux: Install Java
Many developers and programmers choose to use a Linux system as their work environment because of its stability, speed, and ease of use. To get started with programming Java, or to simply run Java applications or applets on Linux, you will need to install the appropriate Java software package. Although this is pretty easy to do, the instructions will vary depending on a user’s Linux distribution, what version of Java they wish to use, and whether they need the JDK (Java Development Kit) or just the JRE (Java Runtime Environment).
Linux: Setup Mail server
Setting up a mail server on a Linux system is useful for hosting email for a domain name, or even just to have local email capabilities. Local email in itself is a convenient feature on a machine used by many users, and even if there is no such traffic, many services dump their reports and messages into e-mails, which is delivered to the root user locally, so the sysadmin will be notified on any events of interest when they log in and switches to root user.
Setup FTP server on Linux
FTP, which stands for “File Transfer Protocol,” is a useful way for transferring files between a client and a server. Depending on the permissions granted to a user, they can traverse directories on the server, download the files to their local computer, and also upload files from their computer to the server. Usually, servers are kept secure by only allowing users with accounts to login via FTP, but it is also possible to configure anonymous authorization, which allows anyone to connect to the server to download and/or upload files.
List of Git GUI applications for Linux
Git is normally used from the command line, but users interacting with lots of repositories on a regular basis may find it easier to use a GUI based application for Git. A GUI based Git application can provide visual representation of Git repositories, which makes them easier to make sense of. Many apps also have user friendly interfaces that are easy to use as opposed to memorizing a bunch of Git commands.
How to install tar.gz file on Linux
.tar.gz file format is a tar archive that has been compressed with gunzip compression. These archives are designed to be opened on Linux systems and can contain any type of files within them. Sometimes, software comes packaged in a
.tar.gz file, and users can extract its contents in order to install what is inside.
How to install RPM package on Ubuntu Linux
Software installation packages for Linux systems will sometimes come in the form of an RPM file. These are files intended for installation on RHEL-based Linux distributions like Red Hat Enterprise Linux, Fedora, CentOS, etc. On Ubuntu, the equivalent packages are DEB files. However, it is possible to convert RPM files to DEB and install them on Ubuntu Linux.
How to install Yum on Linux
Yum is a package manager for Linux systems that rose to prominence for being the default package management system for Red Hat Enterprise Linux and its derivative distributions for many years. It has since been replaced by dnf package manager, which is a fork of yum that has been developed to be faster, more efficient, and have better documentation. Modern Linux distros only use yum as a compatibility layer for dnf, in order to accomodate legacy Bash scripts and old commands.
How to install Brew on Linux
Homebrew (or just “Brew”) is a package manager that is well known as the go-to package management tool for MacOS, but it also works on Linux systems. It has been providing Apple users with a means of installing Linux packages on their devices for many years now, and the development has since expanded it into a tool for Linux as well. Homebrew is free and open source, and its big catalog of installable software has made it an attractive supplement to built in package managers such as apt and dnf on some systems.
