Argo CD

Argo CD is a continuous delivery tool for Kubernetes.

Installation of cli on mac

brew tap argoproj/tap
brew install argoproj/tap/argocd

Installation in minikube

In Kubernetes hello world we have created kuberentes instance and we have run simple service. For that we have used minikube. Now we are going to use it for installing Argo CD. See also https://argoproj.github.io/argo-cd/getting_started/ for more details.

kubectl create namespace argocd
kubectl apply -n argocd \
    -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Change the argocd-server service type to LoadBalancer:

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

And forward port:

kubectl port-forward svc/argocd-server -n argocd 8080:443

Now you can access argocd by https://localhost:8080/. Username is admin and the password:

kubectl get pods -n argocd -l app.kubernetes.io/name=argocd-server -o name | cut -d'/' -f 2

This allows you to login. You can use CLI to change password and admin kubernetes.

argocd login localhost:8080

argocd account update-password
argocd relogin

Now you can sync a repo with argo cd by:

argocd app create flaskhelloworld \
  --repo https://github.com/sbartek/sample_flask_app.git\
  --path flaskhelloworld \
  --dest-server https://kubernetes.default.svc \
  --dest-namespace default

Then one can set argo cd to automatically sync an application.

argocd app set flaskhelloworld --sync-policy automated
