Bogdan Dobrelya e1e304c4f9 Add packer build for docker container

* Add docker Ubuntu Trusty packer template.
* Rework cmtools to install ansible and puppet
* Add support for Vagrant provider docker.
* Containers will share the host system docker daemon
  and images in the storage, so may be run nested.
* Ensure the rsyslogd and sshd is running in containers.
* Also ensure the /var/log/solar dir, which is required for docker.
* W/a Solar-hardcoded and vbox specific ssh key paths
  for docker case.
* Update FAQ and docs

Depends-on: I881d362968a10d816cbd368cb185900dfaa0b3bc
Partial-bug: #1547587

Note, vagrant does not support vm.network and exec based
provisioning for docker, so there are workarounds.

FAQ

Why nodes/transports have hardcoded keys, ips and other inputs ?

This is temporary situation, we will improve it in near future.

I want to use different SSH keys

Just update resource for example:

solar resource update ssh_transport1 '{"key": "/path/to/some/key"}'

I want to use passwords not keys

Just update resource:

solar resource update rsync1 '{"password": "vagrant", "key": null}'

Note

You need to change it for all transport resources (ssh and rsync by default).

How can I run solar worker ?

If you use vagrant then you can just sudo start solar-worker as vagrant user.

How can I configure solar ?

There are several places where we search for config values:

.config file in CWD or in path from SOLAR_CONFIG env variable
if env SOLAR_CONFIG_OVERRIDE contains valid path then it override previous values
.config.override in CWD
You can also set upper-cased env variable which matches one of those in config

What database can I use with solar ?

By default for simplicity we use sqlite. On our vagrant environment we use single node riak. You can also use multiple nodes riak, with some strong consistent buckets.

Where can I find solar examples ?

Example resources, composer templates and examples itself are located: https://github.com/openstack/solar-resources

Can I run solar nodes with docker ?

Yes, although that is an experimental feature and currently supports only a single network interface per a container. Note, that before to run the vagrant up --provider docker command, the following preparations must be done at the host system:

# docker pull solarproject/riak
# git clone https://github.com/kiasaki/docker-alpine-postgres.git
# cd docker-alpine-postgres
# make build && cd -

This will allow the solar nodes to run required nested docker containers.
