spike with k3d + argocd + devspace ?

K3D

Just start with Docker Desktop:

k3d cluster create --config democluster.yaml


kubectl cluster-info
k3d_demo ➤ kubectl cluster-info
Kubernetes control plane is running at https://0.0.0.0:6443
CoreDNS is running at https://0.0.0.0:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
Metrics-server is running at https://0.0.0.0:6443/api/v1/namespaces/kube-system/services/https:metrics-server:https/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

k get nodes

kubectl config get-contexts

k3d cluster delete democluster

k3d cluster list

k3d cluster start democluster

Argo

• setup argo: https://argo-cd.readthedocs.io/en/stable/getting_started/#1-install-argo-cd

  kubectl create namespace argocd kubens argocd

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

  k get pods --watch k port-forward svc/argocd-server 8080:443 k get secret argocd-initial-admin-secret -o yaml base64 decode the password

  open localhost:8080 login with admin and password

argocd application yaml: https://github.com/argoproj/argo-cd/blob/master/docs/operator-manual/application.yaml https://argo-cd.readthedocs.io/en/stable/operator-manual/declarative-setup/

k apply -f argocd_application.yaml
