[Kapil Thangavelu <kapil.thangavelu@xxxxxxxxxxxxx>]

I'm super busy and traveling till next friday. Quite alot of this is
personal setup and works for me, its not productized yet for end users..
but i've tried to automate the bulk in hopes that it will help you guys get
started. I've dropped an ansible ec2.yaml playbook file into jlxc tools
that automates 90% of the setup.

grab a checkout of https://github.com/kapilt/juju-lxc

edit ec2.yml  tweak instance_type, region, key, and trusty_image to taste.
you must tweak session_id if sharing accounts or destroying server... its
there for idempotent requests on ec2 server creation.

ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook -v ec2.yml

after that  on the instance (use ipaddress from ansible output)

lxc-clone -B btrfs precise-template myenv-boot
sudo lxc-start -d -n myenv-boot
sudo lxc-ls --fancy --running | grep myenv-boot

grab ip address

construct environments.yaml

  environments:
     myenv:
        type: manual
        bootstrap-user: ubuntu
        bootstrap-host: $ip_address

juju bootstrap -v --debug

add 5 trusty containers

jlxc-add -n 5 -b trusty-template --series=trusty -e myenv

add 5 precise containers (precise is series default atm)

jlxc-add -n 5 -b precise-template -e myenv

jlxc-destroy -e myenv  will wipe all containers but the bootstrap from the
environment..

For ftesting charms or setting up dev environments. i typically do a
reset.sh script with

jlxc-destroy -e myenv
juju-deployer -TW  # to clear out extraneous services with no untis
jlxc-add -n 8  -e myenv -b precise-template


and then either run juju-deployer again with a workload or use env as
desired.

hth,

kapil
