Helm – Linting (Kubernetes)

March 30, 2026cloud, DevOps, Docker / Kubernetes, KubernetesPixpaSeecoding Technologies

Creating your own Helm charts can mean facing potential errors, thankfully Helm has tools to help. Linting Most of us (including myself) have made an error when writing YAML. It can be an inadvertent space, or a character in the wrong place. A linter helps check that YAML file is written in the correct format […]

Introducing Argo CD and GitOps (Kubernetes)

March 27, 2026DevOps, Docker / Kubernetes, KubernetesPixpaSeecoding Technologies

My recent blog posts have shown how to deploy resources in Kubernetes, and how Helm is used as a chart (“package”) manager for Kubernetes. Glueing the posts together and it is possible to have CI/CD pipelines deploying resources or charts into Kubernetes clusters. But what if there was another way? CI / CD – The […]

Helm – Creating a Chart (Kubernetes)

March 26, 2026DevOps, Docker / Kubernetes, KubernetesPixpaSeecoding Technologies

Previously I discussed using Helm to install existing charts into Kubernetes (https://geektechstuff.com/2026/03/06/helm-kubernetes-package-manager-kubernetes/), but what if you have a custom self-made app or want to create a bespoke install into Kubernetes? Helm Create Alongside existing Helm charts, Helm gives you the option of creating your own charts. In fact, Helm even gives you a template with […]

March 6, 2026cloud, DevOps, docker, Docker / Kubernetes, KubernetesPixpaSeecoding Technologies

My recent posts have been discussing manually creating Kubernetes resources but, as I pointed out in an earlier post, there is an easier way to deploy Kubernetes resources and that is Helm. What is Helm? Helm is a package manager for Kubernetes. A bit like apt in Debian Linux, or yum in Red Hat Linux. […]

Liveness Checks (Kubernetes)

February 21, 2026DevOps, Docker / KubernetesPixpaSeecoding Technologies

Kubernetes can use a function called a livenessProbe to help identify unhealthy pods or pods that are having issues. The below livenessProbe uses a httpGet to check for response codes between 200 and 400. The probe waits 3 seconds (initialDelaySeconds) before starting. The probe checks for a response every 3 seconds (periodSeconds). The probe flags […]

Kubernetes Pods – Requests and Limits (Kubernetes)

February 15, 2026DevOps, Docker / Kubernetes, KubernetesPixpaSeecoding Technologies

In previous Kubernetes based posts I have created a deployment of replicas, a load balancer service and demonstrated how to test that traffic flows to different pods. But what if I wanted to control how much resource a deployment should use? Resources: Requests and Limits Kubernetes has an resources option for requests and limits, as […]

Testing Kubernetes Load Balancer via Replicas (Kubernetes)

February 14, 2026cloud, DevOps, docker, Docker / Kubernetes, Kubernetes, technologyPixpaSeecoding Technologies

I previously blogged about deploying a replica set of nginx in Kubernetes, with the same static web pages shared from storage. I then did a post about using a load balancer such as Metallb in Kubernetes, with pods available externally via the load balancer. But how about mixing the two together…. Some Python (Flask) When […]

Load Balancer (Kubernetes)

January 18, 2026Docker / KubernetesPixpaSeecoding Technologies

In a previous blog post (K3s Cluster) I wrote how my K3s Cluster sat and waited for an external IP address and never got one. There are solutions for this when running a K3s Cluster, or running a Kubernetes via MicroK8s. MetalLB MetalLB is a load balancer for use in Kubernetes, which helps those running […]
