1. replace kube::KubeError::Api(e) with kube::Error::Api(e)
2. pattern matching requires a full match, therefore we should consider other candidate of kube::Error instead of just kube::KubeError::Api(e)

    let current = match deploys.get(&name).await {
        Ok(current) => Some(current),
        Err(kube::Error::Api(e)) => None,
        _ => None // should actually throw the err

3. this will make Option type here insufficient:
   1. OK path
   2. Not found path
   3. actual error path <- consider use another sum type to do this

make current a Result<Option<Deployment>, Error> maybe a better choice
