Recipe 1: Approving Certificate Signing Requests (CSRs)

When working with Kubernetes, you might encounter situations where you need to approve Certificate Signing Requests (CSRs). This is a common task when adding new nodes to a cluster or issuing certificates for user authentication. To efficiently manage CSRs, you can use the following Kubernetes commands.

[!TIP] Approve Certificate Signing Requests

To list Certificate Signing Requests sorted by their creation timestamp, use:

kubectl get csr --sort-by=.metadata.creationTimestamp

To approve a specific CSR, for example, csr-fm7hw, run:

kubectl certificate approve csr-fm7hw

This process helps maintain the security and integrity of your Kubernetes cluster by ensuring that only valid and verified nodes or users can interact with the cluster.
