So I actually got this working. It think some of my confusion comes from
how to specify 'list' variables. The docker module, says the 'volumes'
parameter was a 'list'. Being new to Ansible and with no volumes example,
I dug around a bit. EC2 module has a 'list' var of instance-ids and this
example:
vars:
instance_ids:
- 'i-xxxxxx'
- 'i-xxxxxx'
- 'i-xxxxxx'
region: us-east-1
tasks:
- name: Start the sandbox instances
local_action:
module: ec2
instance_ids: '{{ instance_ids }}'
So I tried to copy that with docker:
vars:
theVolumes:
- '/etc/foo:/foo'
- '/etc/bar:/bar'
tasks:
- name: run bash
docker:
image=centos
volumes='{{ theVolumes }}'
state=running
stdin_open=yes tty=yes
command=/bin/bash
But docker client does not like that.
<96.119.0.167> REMOTE_MODULE docker image=centos volumes='['/etc/foo:/foo',
> '/etc/bar:/boo']' state=running stdin_open=yes tty=yes command=/bin/bash

Despite the fact that it appears to have parse the volumes correctly, I get
the absolute path error seen above. If I change the command to:
tasks:
- name: run bash
docker:
image=centos
volumes='/etc/foo:foo,/etc/bar:bar'
state=running
stdin_open=yes tty=yes
command=/bin/bash
My guess is that this works with ec2 because that's running locally, but
docker has to serialize the list to the server? I think my other issues
were red-herrings and I was getting confused reading the code. How does
the docker module know that a string with commas in it is a list?
if self.module.params.get('volumes'):
self.binds = {}
self.volumes = {}
vols = self.module.params.get('volumes')
for vol in vols:
Is the fact that it is annotated a 'list' in the module spec (volumes=
dict(default=None, type='list')) make Ansible 'pre-parse' that String into
a List? Should the user really have to change how they specify a list
based on whether it is executed locally or remotely? I am able to use var
if I do this:
vars:
theVolumes:
- '/etc/foo:/foo'
- '/etc/bar:/bar'
tasks:
- name: run bash
docker:
image=centos
volumes={{ theVolumes | join(',') }}
state=running
stdin_open=yes tty=yes
command=/bin/bash
But IMO if their is Ansible magic with lists going on, it should do that
already.
