A zero-dependency Python library for getting the Kubernetes token of a AWS EKS cluster.

No AWS CLI, third-party client or library (boto3, botocore, etc.) required.

pip install tokeks

Assign your credentials to environment variables:

export AWS_ACCESS_KEY_ID="..."
export AWS_SECRET_ACCESS_KEY="..."

from tokeks import Tokeks
tokeks = Tokeks(
    access_key_id=os.environ['AWS_ACCESS_KEY_ID'],
    secret_access_key=os.environ['AWS_SECRET_ACCESS_KEY'],
    region_id='YOUR_REGION_ID',
    cluster_id='YOUR_CLUSTER_ID')
token = tokeks.get_token()

1. Go to project directory

2. Run script:

TOKEN=$(./getekstoken us-west-1 cluster-1)

3. Verify Kubernetes API access:

APISERVER=...
curl -X GET $APISERVER/api --header "Authorization: Bearer $TOKEN" --insecure

If the response is something like:

{
  "kind": "APIVersions", 
  "versions": [
    "v1"
  ],
  "serverAddressByClientCIDRs": [
    {
      "clientCIDR": "0.0.0.0/0",
      "serverAddress": "..."
    }  
  ]
}

(and does not contain "Unauthorized"), you're good to go!

1. API Authorization from Outside a Cluster
2. eks-token
