Set up credentials

Ensure you have the right IAM profile before proceeding with steps

aws sts get-caller-identity --query Arn | grep eksworkshop-admin -q && echo "IAM role valid" || echo "IAM role NOT valid"

AWS Keypair

  • Open a new tab and navigate to AWS console > EC2 > Key Pairs
    • Add a new Key Pair named weaveworks-workshop and save the pem file
    • In your Cloud9 tab, click File > Upload local files, then choose the Key Pair’s pem file that was downloaded. It should have the name weaveworks-workshop.pem

ClusterAPI Credentials

ClusterAPI needs credentials to create and manage clusters. To make our lives easier we’ll create an AWS user with AdministratorAccess.

  • Go to IAM > User > Add User with name ClusterAPI and enable “Programmatic access”
  • After clicking Next, choose “Attach existing policies directly” and choose “AdministratorAccess”
  • Click next until the user is created and store the “Access Key ID” and “Secret Access Key”

Set up environment variables

  • cd aws-gitops-multicloud, then run cp ../gitops-cluster-management/.envrc.example .envrc
  • Open .envrc and start populating fields
    • CAPI_AWS_ACCESS_KEY_ID to your workshop AWS_ACCESS_KEY_ID
    • CAPI_AWS_SECRET_ACCESS_KEY to your workshop AWS_SECRET_ACCESS_KEY
    • GIT_USER to your github username
    • GIT_REPO_NAME to your repo name aws-gitops-multicloud
    • AWS_REGION to us-west-2
    • AWS_SSH_KEY_NAME to weaveworks-workshop that we created earlier
    • we can leave AWS_CONTROL_PLANE_MACHINE_TYPE and AWS_NODE_MACHINE_TYPE as t3.large
  • Finally run direnv allow. Which will export these env vars whenever you’re in the git repo directory.

Kubeconfig for EKS management cluster

  • You should see an eks cluster already provisioned when running

    eksctl get clusters

  • We’ll need kubeconfig credentials. You can get it with

    eksctl utils write-kubeconfig --cluster EKS-YOURCLUSTERNAME

OPTIONAL - if eksctl cluster creation is failing

Run this only in case any error occurs during eksctl cluster creation
