How to deploy an application with Argo CD using a Helm repository

In this blog post I will cover the topic, how to use an existing Helm Chart project and an existing Argo CD instance on OpenShift to deploy an example application. The example application is a Node.js server application I used in several blog posts related to OpenShift. This blog post is in the context of my last blog posts using IasCable and Software Everywhere to setup GitOps. In this last blog post I showed how to setup Red Hat OpenShift and Argo CD and an initial GitOps repository on IBM Cloud and in this blog post we reuse the created environment with IasCable GitOps to create a new application inside Argo CD manually.

Use Software Everywhere and IasCable to setup GitOps on a Red Hat OpenShift Cluster in a Virtual Private Cloud on IBM Cloud

This is a long blog post and the third one related to the Software Everywhere project and IasCable. Our objective in this blog post is to create a customized initial GitOps setup in an IBM Cloud environment. The Software Everywhere project and IasCable CLI do provide an awesome way to eliminate writing Terraform modules for various clouds such as IBM Cloud, AWS or Azure to create and configure resources. We are going to reuse Terraform modules which the Software Everywhere catalog does provide.

“AWS CLI: command not found on” macOS

I had following terminal output "zsh: command not found: aws" after the installation of the AWS CLI on macOS, because AWS CLI uses python and you need to ensure you did configure python right. That make it a little-bit more tricky for me to install that CLI on my machine, compared for example to the IBM Cloud CLI.

Bash scripting to ensure Kubernetes resources are deleted in synchronization

Sometimes we need to ensure that resources in Kubernetes are fully deleted before we setup other resources. In Kubernetes the timing and the synchronization can be very import and relevant. In that blog post we see a function of a bash script, that exactly does that job for namespaces. We are using a “for loop” combined with a nested “while loops” and other functionalities in bash to address that topic.
