Bug ID: 1096849
           Summary: docker daemon for epel7 doesn't allow for additional
                    options
           Product: Fedora EPEL
           Version: epel7
         Component: docker-io
          Severity: medium
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]

Description of problem:
For el6, epel's docker build creates /etc/sysconfig/docker, which allows other
options to be passed to the docker daemon. the systemd unit files for epel7's
docker build do not.

Version-Release number of selected component (if applicable):
docker-io-0.10.0-2.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. yum install docker-io
2. less /usr/lib/systemd/system/docker.service

Actual results:
There is no $other_args defined in the systemd unit file, nor is there an
/etc/sysconfig/docker in which to define the options.

Expected results:
Same as the el6 docker. You should be able to pass additional arguments for
bridging, dns, or restart options

After poking around systemd a bit more, it appears that this can be done
systemd internals by creating /etc/systemd/system/docker.service.d/bridge.conf
or similar with the options I need. This option doesn't appear to be documented
well, but it seems to work fine and be the 'proper' way.

Jim can you document this?  So we can add it to the docker package?   Should we
add a  /etc/systemd/system/docker.service.d/ to the docker package?

I'll try to document something sane for this.

I'm not certain that adding the directory to the package is 'proper', as no
other packages appear to provide similar directories. It's possible it should
simply go into /usr/share/doc/docker-io-*/ as an options example file.

OK that sounds good.  BTW In rhel7 the package will be called docker not
docker-io.  Which I wish we would fix in Fedora and RHEL6/Centos6.

I can't find any docker package on rhel7. docker-io is there (version
1.0.0-1.el7) but /etc/sysconfig/docker seems to be an HTML page...
I'll check the docs in /usr/share/doc/docker-io*

And I can't use any more (it seems) the HTTP_PROXY env variable. docker tries
to resolv docker.io...

You need to enable the extras repo.

I think you do this via

# subscription-manager repos --enable=rhel-x86_64-server-extras-7
# subscription-manager repos --enable=rhel-x86_64-server-optional-7

This package is being removed from EPEL since there is now a supported version
of docker in the released rhel7 repositories.
