Subject: Disallow docker-compose to use swap space
X-Git-Tag: 3.6.1~20

Disallow docker-compose to use swap space

- if swap memory is active on any host, the docker-compose will add it
  on top of JVM process memory. This will exceed the total memory
   reservation of the container, eventually cause restart.
- swap limit can not be lower than the total memory limit, thus given
  3G. this will disallow docker-compose to use swap space
