Kubernetes and curl

Internal

• Kubernetes Operations

Invoking into the API Server from Inside a Pod

TOKEN=$(cat /var/run/secrets/kubernetes.io/serviceaccount/token); \
curl -sSk -H "Authorization: Bearer ${TOKEN}" https://kubernetes.default/api/v1/namespaces/

-k in the command above instructs curl to execute in insecure mode. We can actually run it in secure mode because we have access to the certificate:

TOKEN=$(cat /var/run/secrets/kubernetes.io/serviceaccount/token); \
curl -sS -H "Authorization: Bearer ${TOKEN}" \
--cacert /var/run/secrets/kubernetes.io/serviceaccount/ca.crt \
https://kubernetes.default/api/v1/namespaces/
