Local KinD Management Cluster w/ ArgoCD

This sets up a local Kubernetes cluster using KinD (Kubernetes in Docker) and installs ArgoCD and uses it to sync the following applications onto the cluster:

• argocd (argocd syncs itself!)
• nginx-ingress
• cert-manager
• linkerd
• crossplane

It then allows you to create AWS resources using Crossplane such as an entire EKS cluster as shown below.

Getting Started

• Make sure you have KinD installed:

  brew install kind

• Create the KinD cluster from the config:

  kind create cluster --config ./kind/v1.20-config.yaml

• Install ArgoCD using kustomize so it can fetch all the other applications

  kubectl apply -k ./argocd

• Create secret to contain AWS Credentias (these credentials will have to be close to Admin as you need to create many AWS resources)

  # Replace `[...]` with your access key ID`
  export AWS_ACCESS_KEY_ID=[...]
  
  # Replace `[...]` with your secret access key
  export AWS_SECRET_ACCESS_KEY=[...]
  
  # Create a temporary file to hold the credentials
  echo "[default]
  aws_access_key_id = $AWS_ACCESS_KEY_ID
  aws_secret_access_key = $AWS_SECRET_ACCESS_KEY
  " > ./aws-creds.conf
  
  # Create a Kubernetes secret using this file
  kubectl --namespace crossplane-system \
      create secret generic aws-creds \
      --from-file creds=./aws-creds.conf
  
  # Delete this temp file
  rm ./aws-creds.conf

• Create a AWS EKS Cluster using Crossplane by applying the eks-cluster.yaml or eks-cluster-medium.yaml. This is a slightly modified version of @vfarcic's code found here.

  kubectl apply -f ./crossplane-eks-cluster/eks-cluster.yaml
  kubectl apply -f ./crossplane-eks-cluster/eks-cluster-medium.yaml

• Observe the creation of the resources:

  kubectl get managed,compositecluster,clusterclaim
