argocd
=======
1. managing the cluster
2. k8 application deployments

kubectl create namespace argocd-1
kubectl apply -n argocd-1 --server-side --force-conflicts -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

curl -sSL -o argocd-linux-amd64 https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64
sudo install -m 555 argocd-linux-amd64 /usr/local/bin/argocd
rm argocd-linux-amd64

kubectl patch svc argocd-server -n argocd-1 -p '{"spec": {"type": "LoadBalancer"}}'

argocd admin initial-password -n argocd

everything is called as application

source -> git is single source of truth
destination -> K8s cluster
sync policy -> how frequently argocd should go and check github.. by default every 3min

1. OIDC cluster
2. policy creation
3. eks service account -> creates IAM role and map sa with IAM role
4. install through helm charts

argocd is git ops tool. we are using argocd to manage eks cluster and recently we started deploying few applications with argocd. in argocd everything is application. it has source, destination and sync policy. when we update source it will automatically sync that to destination

we are managing namespaces, drivers, load balancer controller, etc through argocd. application deployments also through argocd. our CI pipeline updates image versions in helm values file based on environment, our argocd application syncs it automatically
