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

[dommmel]

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

[zhucegep]

I really need this feature: #597

[mishak87]

@zhucegep you can try crane which supports it

[razic]

@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

[zhucegep]

@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

Any updates on docker-compose supporting the device option?:

--device=[] Add a host device to the container (e.g. --device=/dev/sdc:/dev/xvdc:rwm)

[gastonmorixe]

cpuset?

[bfirsh]

I've added some examples of pull requests adding docker-compose.yml options in case anybody needs an example to help them implement these.

[gastonmorixe]

@bfirsh cool, may I know why can't we add a fallback way to send whatever run param we want? so we are not always behind docker. Soon docker will have logs driver/limits, I'd love to use that even under a RC, but I can't without patching compose too.

Thanks

[mishak87]

@imton IMO it is necessary to synchronize feature releases of docker with compose so it does not lag behind. Maybe using it for regression/integration tests so it is always necessary to keep it up-to-date.

But since receiving new name, lets hope it will be also receiving the attention it deserves!

[gastonmorixe]

@mishak87 while I understand what you say, I don't agree. I think docker changes so fast we have to have fallback and for docker's betas/RC we won't be updating compose.

[mishak87]

TL;DR Current state leads to tools/forks like crane which implement more features and react faster. Maybe it would be faster to make decision on format/behaviour and let community to help out with implementation.

@imton That does not make sense to me from product perspective. We are talking about tool that orchestrates docker containers by reading single configuration.

I really do appreciate the pace with which docker keeps on significantly improving with each version, but leaving this tool in dust behind is bad. It would be like publishing golang 1.4 but only with tools supporting 1.3 features.

For a docker newcomer, composer is already part of official documentation. I would implicitly assume it is in lock with at least last stable version of docker. It is not useful to me for development and playing with, if I can't use new features.

From technical point of view it is confusing at least for me personally. I would expect compose to contain 90% of generated code from some hashmap of possible config values crossed with docker-py feature set.
Maybe it would make sense to leave it with open-source community so you can focus on docker alone.
Maybe you could decide how configuration should look like and ask for pull requests? I could promise you to make at least one each month for at least a year.

I want to help but there's no in-source docs :( – need add-hosts as well. How do you run the tests?

[bfirsh]

@tj Instructions on how to run the tests is in the contributing docs. Here's an example of adding an option if that's helpful: #830

Give us a shout in #docker-compose on Freenode if you need a hand with anything. :)

[tj]

Would you be against a hosts map? I know it doesn't fit the same model as #820 but something similar to environment like @mishak87 mentioned makes the most sense to me. The naming conventions get a little weird though since it wouldn't be 1:1 with the flags, that feels a little awkward, but let me know what you think!

[gomex]

cpuset was added in which version? I am using 1.2.0 and don't have this option here:

Unsupported config option for sisaudev service: 'cpuset'

[zutherb]

+1

[brianclements]

+1. Especially regarding the --log-driver, but for everything really. Volume containers don't need logging, some temporary containers can use default, and app containers can be specified accordingly.

[Claudweb]

+1 for mac_address

[mnowster]

mac_address and memswap_limit will be in 1.4.

I'm closing this issue as those run options are now covered.

If there are further ones, please open a new issue. Thank you.

[migueleliasweb]

Hey everyone, I just got a problem with --cpu-quota support. After reading some comments here I saw some options were merged, any news about --cpu-quota ?

[Shinoby92]

still nothing about the oom-kill disabling in stack deploy?

[fullbl]

what about sig-proxy?
