I'm looking for a way to export a yaml file from a deployed component but without the cluster specific information.
kubectl get MYOBJECT --export -o yaml > my.yamlbut since "export" is now deprecated (since 1.14 and should normally disappear in 1.18 (didn't find it in changelog), what would be an alternative ?
thanks
Currently the one option is to do -o yaml or -o json and remove the unnecessary fields
There is no consistent way to do this since there is no overall guidelines about defaulting and other live data clean up. That is why it was deprecated. You should keep your source files in git or similar.
Using JQ do the trick.
kubectl get secret <secretname> -ojson | jq 'del(.metadata.namespace,.metadata.resourceVersion,.metadata.uid) | .metadata.creationTimestamp=null'produces exactly the same json as
kubectl get secret <secretname> -ojson --export
