ArgoCD HA Setup for Production

Two types of installation manifests are provided by ArgoCD.

1:- Non-High Availability

2:- High Availability

We will discuss ArgoCD's high availability installation because it is necessary and advised for production use cases.

As stated, for production use, a high-availability installation is advised. The components in the below bundle have been enhanced for high availability and resilience.

ha/install.yaml: Multiple replicas for supported components. [Official repo URL]

For the demonstration, I’m using ArgoCD V2.4.7, and I currently find it to be much more stable.

In my Git repository, you may find a direct link to the aforementioned ArgoCD version.

argocd-ha-install.yaml — This file contains ArgoCD V2.4.7

There are various methods you may use to install argocd-ha-install.yaml on your Kubernetes cluster. On my setup, I use Kustomization.

Latest Argocd manifest :-

https://github.com/argoproj/argo-cd/blob/master/manifests/ha/install.yaml

ArgoCD V2.4.7 manifest :-

# If you want to Deploy using the Kubernetes-native way

# wget https://raw.githubusercontent.com/argoproj/argo-cd/v2.4.7/manifests/ha/install.yaml

# kubectl apply -f install.yaml

OR

# If you want to Deploy using Kustomization

git clone https://github.com/devopsbucket/argocd

cd argocd/HA

# Perform a dry run before the actual deployment to observe the changes.
kustomize build overlays/dev

#Create Namespace Called- argcod
kubectl create ns argocd

#Actual deployment
kubectl apply -k overlays/dev

The output of. # kubectl apply -k overlays/dev

Check to see if all of the pods are operational.

# Kubectl get pods -n argocd

Check the Service Status created by argocd deployments.

# Kubectl get svc -n argocd
