The Underscore Field in Go Structs: Beyond Enforcing Named Initialization

Thu, 30 Jul 2026 09:00:00 -0500

Introduction

The underscore character (_) in Go serves several well-known purposes: ignoring unwanted return values, importing packages solely for their side effects, and as a blank identifier in various contexts. However, there’s a lesser-known use case: adding an underscore field to a struct. This pattern deserves closer examination as it offers more benefits than simply enforcing named initialization.

Understanding the Underscore Field Pattern

Let’s start by examining the pattern in question:

The Importance of Sequential Kubernetes Version Upgrades

Fri, 25 Oct 2024 14:30:00 -0500

Upgrading Kubernetes clusters requires careful planning. While skipping versions (e.g., going from 1.28 to 1.30) may seem tempting, it can introduce unexpected issues. This post explains why sequential upgrades (1.28 → 1.29 → 1.30) are essential and offers tips for safe upgrade paths.

Why Sequential Upgrades Matter

Kubernetes releases new minor versions approximately every three months, and each version contains new features, bug fixes, and deprecations. Skipping versions may create:

Top 4 Kubernetes Anti-Patterns

Many teams fall into anti-patterns that can negatively impact scalability, security, and reliability. In this post, we’ll explore the top 4 Kubernetes anti-patterns, how they can harm your environment, and best practices to avoid them.

Avoiding Namespace Confusion in Kubernetes Deployments

Wed, 21 Aug 2024 02:00:00 -0500

Kubernetes namespaces logically group objects together, providing a degree of isolation in your cluster. Creating a namespace for each team, app, and environment prevents name collisions and simplifies the management experience.

When using namespaces, remember to specify the target namespace for each of your objects and kubectl commands. Otherwise, the default namespace will be used. This can be a debugging headache if objects don’t appear where you expected them.

Set the metadata.namespace field on all your namespaced objects so they’re added to the correct namespace:

yaml
apiVersion: v1
kind: Pod
metadata:
 name: demo-pod
 namespace: demo-app
spec:
 # ...

Include the -n or --namespace flag with your kubectl commands to scope an operation to a namespace:

bash
# Get the Pods in the demo-app namespace
$ kubectl get pods -n demo-app

This flag is also supported by Kubernetes ecosystem tools such as Helm. For a simpler namespace-switching experience, try kubens to quickly change namespaces and persist your selection between consecutive commands.

Why Broken Pod Affinity/Anti-Affinity Rules Can Disrupt Your Kubernetes Deployments

Tue, 20 Aug 2024 21:00:00 -0500

Pod affinity and anti-affinity rules allow you to instruct Kubernetes which Node is the best match for new Pods. Rules can be conditioned on Node-level characteristics such as labels, or characteristics of the other Pods already running on the Node.

Affinity rules attract Pods to Nodes, making it more likely that a Pod will schedule to a particular Node, whereas anti-affinity has a repelling effect which reduces the probability of scheduling. Kubernetes evaluates the Pod’s affinity rules for each of the possible Nodes that could be used for scheduling, then selects the most suitable one.

The affinity system is capable of supporting complex scheduling behavior, but it’s also easy to misconfigure affinity rules. When this happens, Pods will unexpectedly schedule to incorrect Nodes, or refuse to schedule at all. Inspect affinity rules for contradictions and impossible selectors, such as labels which no Nodes possess.

Why Not Using Liveness and Readiness Probes in Kubernetes Can Hurt Your Applications

Tue, 20 Aug 2024 02:40:00 -0500

When deploying applications on Kubernetes, ensuring their reliability and resilience is critical. A key aspect of achieving this is the proper use of Liveness and Readiness probes. These probes help Kubernetes monitor the health of your Pods and react appropriately when things go wrong. However, they are often overlooked or misconfigured, leading to avoidable issues in production environments.

In this post, we’ll explore why Liveness and Readiness probes are essential, how they work, and provide examples of how to implement them in your Kubernetes deployments.

Why Deploying Containers With the 'Latest' Tag is a Bad Idea

Tue, 20 Aug 2024 02:26:00 -0500

Deploying containers with the “latest” tag is a common practice, especially during the development phase. However, as you transition to production environments, relying on the “latest” tag can introduce significant risks and challenges. In this post, we’ll explore why using the “latest” tag is a bad idea and how you can ensure a more stable and predictable deployment process by adopting better practices.
