= kdecode
Decodes K8s secret's data block.
Change namespace with the --namespace or -n flag.
Cluster selection can be done using the --cluster or -c flag to avoid having to change the current context when comparing multiple clusters.
You can limit the output to a single key within the secret with the --key or -k flag.
Additionally, if the secret is a PEM encoded certificate, you can pass the --pem flag to decode the certificate and print the details.
== Examples
.Decode a secret as a PEM certificate and pass the namespace, the cluster and filter to a single key
