Helm Multi-Values Plugin with Argo's CMP
Introduction With the current version of Helm, it’s not possible to merge multiple values files. It will override the list from the preceding values file. While trying to solve this problem, I stumbled upon this custom plugin that can take a folder of values files and split them into individual files. This plugin is what I was looking for to solve my problem. Finally, I want to integrate this plugin into my ArgoCD instance.

Getting Started with Red Hat Developer Hub - Part 2
In this continuation of our getting started with Developer Hub series, we’re diving into the art of crafting templates. These templates will not only streamline your workflow but also serve as the cornerstone for automated deployments. High-level overview Overview The developer initiates the workflow by leveraging the backstage self-service template. This template, in turn, pulls essential skeleton resources from a dedicated software template repository, ensuring consistency and best practices. The developer’s actions trigger the creation of a pull request to the GitOps repository, introducing version-controlled changes to the infrastructure. An admin reviews and approves the pull request. Then, ArgoCD, a continuous delivery tool, provides the database resources according to the approved changes. This seamless integration of backstage, GitOps, and ArgoCD accelerates the development lifecycle. It fosters a collaborative environment where developers and administrators work harmoniously to deliver robust and scalable database solutions.

Upgrading PostgreSQL in Kubernetes
I have been running an instance of bitnami’s version of Postgresql 12 for a while, and I have recently upgraded/migrated data from version 12 to 15. This post doesn’t cover in-place upgrades; instead, it will require you to spin a newer container version. Deploy New Container Image The first step is to deploy a new Postgres container using the updated image version. This container MUST NOT mount the same volume as the older Postgres container.

Forward Openshift Audit Logs to Splunk using Newrelic Fluent Bit
It is common for organizations to send logs to multiple systems—for example, container logs to NewRelic, and audit logs to Splunk for the InfoSec team. Deploying NewRelic using helm chart will also deploy the NewRelic logging deamonset, which utilizes a custom Fluent Bit image with a NewRelic output plugin to forward logs easily. Since the NewRelic Fluent Bit image uses an upstream fluent bit as a base image, it is pre-baked with the Splunk plugin.

ArgoCD with Kustomize and KSOPS using Age encryption
I am a big fan of FluxCD and its integration with secrets management; however, recently, I decided to tinker with ArgoCD. One of the challenges I encountered was secrets management. Although ArgoCD provides flexible integration with most secrets management tools, it requires little extra configuration. So I started my journey to configure ArgoCD with SOPS; there isn’t a direct integration with SOPS. So we will have to use the Kustomize plugin called ksops, which is the suggested tool on Argo’s website and it has pretty good instructions for Argo integration.
