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 […]

Proxmox: Terraform Cloudinit

July 12, 2025DevOps, proxmoxPixpaSeecoding Technologies

Back in May I used Terraform to create some containers in my Proxmox environment. Adjustments to Proxmox Since my original post I have turned my single Proxmox node into a Proxmox cluster, added some shared storage and created a cloudinit template. With all of that in place I’m now going to look at deploying a […]

Proxmox: Cloudinit

July 8, 2025DevOps, Linux, technologyPixpaSeecoding Technologies

In this blog post I am going to look at creating a virtual machine (VM) template that has cloudinit so that some settings are automatically configured at launch of any VMs built from the template. The first step towards a cloudinit template is finding a cloudinit image. Ubuntu Cloudinit Images Ubuntu maintains a page for […]

K3s Cluster (Kubernetes)

July 2, 2025DevOps, Docker / KubernetesPixpaSeecoding Technologies

With my Proxmox cluster running I have decided to delve back into Kubernetes in a local cluster. My Proxmox hosts are not super powerful (2 cores each and a mixture of 4GB and 8GB) but that should be enough for a K3s cluster. K3s K3s is lightweight Kubernetes (K8s) built for unattended, remote locations or […]

Proxmox: Adding A Share

June 30, 2025DevOps, proxmoxPixpaSeecoding Technologies

My little Proxmox cluster is coming into iit’ss own with a few virtual machines (VMs) and containers running across the 2 nodes of the cluster. However, I have been downloading operating system ISOs and container templates (CT) to each node when needed, and backup is currently non-existent. Time to do something about that…. Sharing is […]

Linux: Creating an NFS Share

June 28, 2025DevOps, LinuxPixpaSeecoding Technologies

Sharing data across multiple computers can be achieved in many different ways, in this blog post I’m going to use an Network File System (NFS) share. Server The server will require nfs-kernel-server installing and at least one share setting up: I’m going to be using the share to share out a basic HTML page via […]

Proxmox Cluster

June 18, 2025DevOps, proxmoxPixpaSeecoding Technologies

A Proxmox cluster allows for High Availability (requires 3 nodes) and resource sharing. In a production data centre it would allow for Virtual Machines (VMs) or containers to move between nodes to help keep production systems running. It is not something I’ve done previously as I only had 1 device running Proxmox. However, I’ve now […]

GitHub Codespaces: Creating A Codespace

June 14, 2025DevOps, githubPixpaSeecoding Technologies

I generally use a Raspberry Pi as my home Visual Studio Code server, allowing me to code in a dedicated developer environment. Sometimes though I might be away from home on a device that can’t connect back. So what’s a geek that wants to code to do in those circumstances? GitHub Codespaces GitHub Codespaces provide […]
