Hands-On Microservices with Kubernetes

Getting started with Argo CD

Argo CD follows best practices and expects to be installed in a dedicated namespace on your Kubernetes cluster:

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

Let's see what was created. Argo CD installed four types of objects: pods, services, deployments, and replica sets. Here are the pods:

$ kubectl get all -n argocdNAME                                        READY  STATUS RESTARTS  AGEpod/argocd-application-controller-7c5cf86b76-2cp4z 1/1   Running  1  1mpod/argocd-repo-server-74f4b4845-hxzw7             1/1   Running  0  1mpod/argocd-server-9fc58bc5d-cjc95                  1/1   Running  0  1mpod/dex-server-8fdd8bb69-7dlcj                     1/1   Running  0  1m

Here are the services:
