docker-compose.yml should support every docker run option

[bfirsh]

Notable things missing:

• add-host fig.yml support for --add-host? #597 Add extra_hosts to yml configuration --add-hosts #1158
• cpuset Added support of cpuset and memswap_limit options in fig.yml. #685
• device df87bd91
• memswap_limit Added support of cpuset and memswap_limit options in fig.yml. #685
• mac_address added in this commit: b76ac6e6

The following run options aren't in docker-py; cpuset-mems, cpu-period, cpu-quota, oom-kill-disable, sig-proxy

Related: #363

Examples: #293 #830

Any progress with add-host #597? In docker-py support is already present docker/docker-py#400 from 0.7.0.

Ideally if configuration would look like this

hosts:
   hostname: ip

AFAICT support for "device" is also present in docker-py (see docker/docker-py#373)

+1 for #597

[zhucegep]

I really need this feature: #597

[mishak87]

@zhucegep you can try crane which supports it

@bfirsh are memswap_limit and cpuset not integrated into docker-compose yet?

[razic]

also i'm trying to use cpu_shares which looks to be defined here, but doesn't seem to actually be working... https://github.com/docker/fig/blob/master/compose/service.py#L21

@mishak87 thank you, I had implement this feature on environment variable.

usage:

environment:
    HOSTS:  "zookeeper zookeeper.example.com\n172.17.42.1 my.own.com"

impl:

#! /bin/bash
echo  "# host config by docker" >> /etc/hosts
echo  "$HOSTS" | while read line 
do
  link_service_name=`echo $line | cut -d" " -f1`
  ip=$link_service_name
  # if does not contain "." then change it to ip from env
  [[ $ip =~ "." ]] || ip=`env | grep TCP=tcp:// | grep -i $link_service_name | cut -d"/" -f3 | cut -d":" -f1 | sort | uniq`
  # replace service name to ip, and echo to /etc/hosts
  echo $line | sed s/$link_service_name/$ip/g >> /etc/hosts
done
