Move Kubernetes Resource from one namespace to another

Move Kubernetes Resource to other Namespace

kubectl get -n <old_namespace> <kind> <resource> -o json  |\
jq '.metadata.namespace = "<new_namespace>"' |\
kubectl create -f - &&\
kubectl delete -n <old_namespace> <kind> <resource>

Beware that this will copy the status section of your resource to the new one, and depending on the kind, this may have non-intended repercussions, but this should be fine for ConfigMaps and Secrets.

Adding here what I read on Reddit regarding this script because I think it might be useful (and for myself to remind me because I've starred this gist):

I see what you're saying because of the &&. Still I wouldn't simply trust that a successful exit of kubectl would be enough for me to go and delete the resource. But I'm very cautious. Personally, I'd query the API again and check the status of the newly-created one first... You could use jq again, if you want to keep it in a shell script

@PrimeDominus This is what I explained in the comment above. But always a good idea to add more information :). Thanks for starring the gist !
