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.
Running containerized WordPress in a Kubernetes cluster is a fantastic way to make sure that your website can horizontally scale with increased traffic demands. In this tutorial, we will see how to deploy a WordPress website in a Kubernetes cluster on a Linux system. We will be using the easy method, which is via the helm package manager for Kubernetes. Afterwards, it is simple enough to customize the install to fit your needs.
The kubectl command is the primary way of interacting with your Kubernetes cluster. It is safe to say that Linux administrators will be using the command on a constant basis when they are in charge of a Kubernetes environment. However, due to the sheer amount of command options available, it can be intimidating for newcomers and tricky to learn. Even longtime users may forget a command every once in a while and that is why we have created this tutorial full of kubectl command examples.
Kubernetes is open source software that allows us to manage containerized applications across node systems. When it comes to managing a Kubernetes cluster, one of the most important aspects of administration is to keep constant tabs on the logs. These logs give us valuable information about the performance and overall health of our Kubernetes cluster. In this tutorial, we will see how to manage and troubleshooting Kubernetes logs on a Linux system.
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.
The kubectl command is how administrators interact with and manage a Kubernetes cluster on a Linux system. It is an essential command line tool that works with all Kubernetes cluster envrionments like Amazon Web Services, Google Cloud Platform, or a cluster on your own hardware (e.g., kubeadm). Managing Kubernetes clusters at scale can be a challenge at first, but mastering the kubectl command will make it much easier.
Kubernetes gives system administrators the means to manage containerized applications. To get started, we need to deploy an application inside of our Kubernetes cluster. From there, Kubernetes will manage many aspects of our application, plus give us tools to interact with it as needed. In this tutorial, we will go through the step by step instructions to deploy an application in Kubernetes on a Linux system.
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.
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.
Python is a popular programming language used in a wide range of applications, from data analysis and scientific computing to web development and artificial intelligence. Bash is a powerful scripting language used primarily in Unix and Linux environments for automating tasks and running commands. By combining the two languages, developers can create powerful scripts that can automate complex tasks and workflows. In this article, we’ll explore various techniques for running Python scripts with bash, including passing arguments, activating virtual environments, and running scripts in the background. We’ll also provide examples of real-world scripts that demonstrate these techniques in action.
The Linux operating system gives us many ways to measure the performance of our computer, including individual components such as the hard drive. There are multiple tools for the job, and it is also possible to use built in tools and create our own test to measure real results. In this tutorial, we will see how to use a Bash script to test the transfer speed of a hard drive on a Linux system. We will also learn about some other tools which can supplement our Bash script and give us and give us additional data points when it comes to the transfer speed of our hard drive, including read and write speed.
MX Linux has quickly risen in popularity in recent years and is one of the most trending Linux distributions currently. Since most Linux users are very familiar with Ubuntu Linux already, it is common to use it as a base for comparison to other distros like MX Linux. Knowing how these two distributions stack up and compare to each other can lead users to a reliable conclusion about which one would be the best for their preferences and workflow.
