Easy Kubernetes metrics and cluster management with K9s, Kubectx, and Kubens

Efficiently retrieving Kubernetes metrics is the beginning of cluster performance optimization. Cluster metrics such as logs and resources descriptions are crucial as they map the health of your cluster. There’s a Kubernetes tool called K9s that lets you access your Kubernetes cluster metrics swiftly using short keys. K9s prioritizes aesthetics and performance as it displays its contents and functions in an aesthetically pleasing UI.

A guide to static analysis in JavaScript and TypeScript

The demands of a tight production schedule can make it difficult to produce consistent, readable, and concise code in the lead-up to a manual code review. This often makes the process stressful — if not outright dreaded. Standard tests are a critical part of development that verify that our code produces the expected outputs. But great tests don’t always lead to good code.

Essential tips for automating DevOps workflows

Implemented well, automation can be a powerful tool for accelerating and scaling DevOps processes to keep your team building and shipping code quickly. But knowing what and how to automate DevOps workflows can be challenging; every organization’s DevOps practices are unique, and there’s no one “right” way to approach automation. Let’s look at a few tips for approaching DevOps workflow automation to help your team move faster.

Pre- and post-deployment testing methodologies for CI/CD

Your team has worked hard on a software product for months, and it’s finally ready to release to your users! But then the worst-case scenario happens: a wide release soon indicates that the software is plagued with bugs and performance issues, resulting in poor reviews and widespread user dissatisfaction.

Why it's important to upgrade your Mattermost Server

Upgrading your Mattermost server involves a bit of research, preparation, and downtime. The pressure to keep your Mattermost instance healthy and reduce downtime for a core system within your organization can be intimidating. Recently, we worked with a handful of customers who were experiencing issues upgrading from Mattermost v5.37 and v5.39 to v6.x. Unfortunately, migration scripts were required to make significant database changes, and there was an issue in product performance.

How to use GitHub Actions securely

GitHub is one of the most popular source control platforms available. It relies on Git concepts, and millions of developers use it. GitHub Actions embrace all aspects of what source control needs, such as branching, pull requests, feature flags, and versioning. It also integrates nicely into third-party continuous integration and continuous development (CI/CD) pipelines or deployment tools like Azure DevOps, Jenkins, GitLab, and Octopus Deploy.

Building a Custom Grafana Dashboard for Kubernetes Observability

Distributed systems open us up to myriad complexities due to their microservices architecture. There are always little problems that arise in the system. Therefore, engineering teams must be able to determine how to prioritize the challenges. Viewing logs and metrics of such systems enables engineers to know the shared state of the system components, thereby informing the decision-making on what challenge needs to be solved most immediately.
