Hi,
I am developing a new beat and followed docs at [https://www.elastic.co/guide/en/beats/devguide/6.6/creating-beat-from-metricbeat.html](https://www.elastic.co/guide/en/beats/devguide/6.6/creating-beat-from-metricbeat.html).
```auto
$ pwd
/Users/bob/workspace/go.ws/src/github.com/elastic/beats
$ git branch
* 6.6
master
$ uname -spr
Darwin 16.7.0 i386
$ go version
go version go1.11.5 darwin/amd64
$python --version
Python 2.7.15
$ virtualenv --version
16.4.0
$ docker --version
Docker version 18.09.2, build 6247962
```
I am at root folder of newly created beat , `make setup`, `make update`, `make` works fine and I am able to run my new beat in my laptop, only the `release` target fails.
Any help is highly appreciated,
```
$ make release -d
