Purpose

This repository is for testing and playing with K8S and Argocd. It is intended to be able to easily initialize infrastructure on local k8s cluster - using docker desktop.

Prerequisites

• Installed Docker Desktop
• Enable Kubernetes in Docker Desktop
• Installed kubectl and helmcli
• Switch to docker-desktop context in kubectl

List all argo-cd chart versions

helm search repo argo-cd/argo-cd --versions

Install ArgoCD

# Install the chart
helm install argo argo/argo-cd --namespace=argocd --create-namespace --version 7.3.3 --values argocd-values.yaml

Configuring the argo-cd chart

See all possible values, add them to the argocd-values.yaml file and install the chart with the file.

helm show values argo/argo-cd

Upgrade the chart

# Upgrade the chart
helm upgrade argo argo/argo-cd --namespace=argocd --version x.x.x --values argocd-values.yaml

Others

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

# If NodePort is not set use port forwarding <SHOULD NOT BE NEEDED>
kubectl port-forward service/argo-argocd-server -n argocd 8080:443
