# Kube Apply Command

Kube apply command is the command that be declarative way (using definition file) , the different thing between imperative way (kubec create etc.) is `last apply configuration`\
\
Everytime we worked on the declarative way(`kube apply)`  we need to have file  template and after we run command it will create `live object configuration` it is yaml file that store data like a template but it will have more additional field so it has one field called `last appyly configuration(json format)`It store the last change value in json format the benefit of this is when we remove field from `template` it will also remove on `live object configuration` but does not for `last apply configuration`  so we can use that to detect the remove field
