ArgoCD Architecture

ArgoCD Architecture

ArgoCD is composed of three mains components:

API Server: Exposes the API for the WebUI / CLI / CICD Systems

Repository Server: Internal service which maintains a local cache of the git repository holding the application manifests

Application Controller: Kubernetes controller which controls and monitors applications continuously and compares that current live state with desired target state (specified in the repository). If a OutOfSync is detected, it will take corrective actions.

Install Argo CD

All those components could be installed using a manifest provided by the Argo Project:

kubectl create namespace argocd
kubectl apply -n argocd -f

Install Argo CD CLI

To interact with the API Server we need to deploy the CLI:

VERSION=$(curl --silent "" | grep '"tag_name"' | sed -E 's/.*"([^"]+)".*/\1/')

sudo curl --silent --location -o /usr/local/bin/argocd$VERSION/argocd-linux-amd64

sudo chmod +x /usr/local/bin/argocd
