Healthcheck script execution permissions in alpine

[Boris]

Healthcheck scripts didn't work (timeout and service unhealthy in docker ps) in alpine images of rabbitmq and postgres, until i added the following command in Dockerfile:
RUN chmod +x /usr/local/bin/docker-healthcheck

Docker CE v17.03.0-ce-mac2 (15654)

You need to invoke chmod +x on your local copy of the script if you didn't use git clone to download the repository before building. 👍
