ArgoCD Installation

1. Install Argo CD client

macOS

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

Linux

ARGO_CD_LATEST=$(curl --silent "https://api.github.com/repos/argoproj/argo-cd/releases/latest" | grep '"tag_name"' | sed -E 's/.*"([^"]+)".*/\1/')
curl -sSL -o /usr/local/bin/argocd https://github.com/argoproj/argo-cd/releases/download/${ARGO_CD_LATEST}/argocd-linux-amd64
chmod +x /usr/local/bin/argocd

2. Install Argo CD server components

Create Argo CD's namespace in Kubernetes

kubectl create namespace argocd

Install the stable Argo CD's version

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

3. Change the default admin password

Expose the argocd's port - in another terminal panel input:

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

Output

Forwarding from 127.0.0.1:8080 -> 8080
Forwarding from [::1]:8080 -> 8080
Handling connection for 8080

Change the pass

argocd_default_pass=$(kubectl get pods -n argocd -l app.kubernetes.io/name=argocd-server -o name | cut -d'/' -f 2)
argocd_new_pass=newpass
argocd login --username=admin --password="${argocd_default_pass}" localhost:8080
argocd account update-password --current-password="${argocd_default_pass}" --new-password="${argocd_new_pass}"
argocd relogin --password="${argocd_new_pass}"

After installation we're able to use as the CLI client so the web UI

CLI

$ argocd app list
NAME  CLUSTER  NAMESPACE  PROJECT  STATUS  HEALTH  SYNCPOLICY  CONDITIONS
