Copy Kubernetes Secret to Another Namespace
Sometimes you just want to share a secret between namespaces, for example, a Docker Registry Credential.
Replace CurrentNameSpace and NewNameSpace with your respective namespaces. Also, change the SecretName, pretty simple
Kubernetes <1.18
kubectl get secret SecretName -n CurrentNameSpace --export -o yaml |\
kubectl apply -n NewNameSpace -f -Kubernetes >1.18
--export flag was removed in version 1.18
kubectl get secret SecretName -n CurrentNameSpace -o yaml |\
sed 's/namespace: CurrentNameSpace/namespace: NewNameSpace/g' |\
kubectl create -f -That's it
