Crossplane EKS

README.md

Steps

1. Create file with the AWS creds called aws-creds.conf

aws_access_key_id = <AWS_ACCESS_KEY_I>
aws_secret_access_key = <AWS_SECRET_ACCESS_KE>

Create the secret:

kubectl -n crossplane-system \
    create secret generic aws-creds \
    --from-file creds=./aws-creds.conf

2. Add cross plane helm repo

helm repo add crossplane-stable https://charts.crossplane.io/stable
helm repo update

3. Install crossplane

kubectl create namespace crossplane-system
helm upgrade --install \
    crossplane crossplane-stable/crossplane \
    --namespace crossplane-system \
    --create-namespace \
    --wait

and the cli

curl -sL https://raw.githubusercontent.com/crossplane/crossplane/master/install.sh | sh

4. Create provider-aws.yaml with

apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
  name: crossplane-provider-aws
spec:
  package: crossplane/provider-aws:v0.22.0

5. Apply the provider

kubectl apply -f provider-aws.yaml

6. Create provider-config-aws.yaml with:

apiVersion: aws.crossplane.io/v1beta1
kind: ProviderConfig
metadata:
  name: default
spec:
  credentials:
    source: Secret
    secretRef:
      namespace: crossplane-system
      name: aws-creds
      key: creds

7. Apply the provider config

kubectl apply -f provider-aws.yaml

8. Create provider-helm.yaml:

apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
  name: crossplane-provider-helm
spec:
  package: crossplane/provider-helm:v0.9.0

9. Apply the provider config

kubectl apply -f provider-helm.yaml

10. Create provider-k8s.yaml:

apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
  name: crossplane-provider-kubernetes
spec:
  package: crossplane/provider-kubernetes:main

11. Apply provider:

kubectl apply -f provider-k8s.yaml

12. APply XRD, composiste etc from OCI registry. Create config-k8s.yaml:

Based on this repo: https://github.com/cem-altuner/crossplane-prod-ready-eks/tree/master/packages/k8s

apiVersion: pkg.crossplane.io/v1
kind: Configuration
metadata:
  name: crossplane-k8s
spec:
  package: cemaltuner/crossplane-k8s:v0.2.14

13. Apply the config:

kubectl apply -f config.k8s.yaml

14. Check the status of the providers:

kubectl get pkgrev

15. Create namespace for a team:

kubectl create namespace team-a

16. Create a ClusterClaim for team-a to create an EKS cluster. Create aws-eks.yaml:

apiVersion: prodready.cluster/v1alpha1
kind: ClusterClaim
metadata:
  name: team-a-eks
  labels:
    cluster-owner: cem
spec:
  id: team-a-eks
  compositionSelector:
    matchLabels:
      provider: aws
      cluster: eks
  parameters:
    nodeSize: small
    minNodeCount: 1
    version: "1.25"

17. Apply cluster definitions:

kubectl -n team-a apply -f aws-eks.yaml

18. Wait for the ClusterClaim to be Ready
