Juju deployer for juju-core.
6
Juju deployer is an automation tool for deploying complex applications
7
with juju. It encompasses most of the properties of a juju environment
8
(relations, config, constraints) along with charm vcs management into
9
a simple definition format. It allows for inheritance between
10
configurations which makes it straightforward to take customize/share
11
a base environment configuration across multiple environments.
13
Deployer was written by Adam Gandleman, and originated from some of
14
Canonical's openstack charm development and deployment, and has seen fairly
15
widespread adoption within canonical for application deployment.
17
There's a new implementation of juju-deployer that supports juju-core
18
and pyjuju. I took the opportunity to add some new features, tests,
19
and docs. When used with juju-core it now uses the environment's
20
websocket api instead of the cli where possible, and also for allow
21
for reporting live changes as the deployment proceeds. Change listing
22
at the bottom of the email.

- Relations only added if they don't exist.
44
- Support for multiple services using the same charm.
45
- Support for automatic retrying of failed relations.
46
- Support for simpler relation definition syntax, either a list of
47
endpoint pairs - [blog, db] or list of endpoint, [targets] can be used. ie. [blog, [db, cache]] can be used.
48
- Uses watches for live feedback of change progress in an environment.
49
- Additional sanity/error checking prior to modifying an environment.
50
- yaml support config file support
51
- multiple inheritance
52
- No support atm for resetting the environment's charm cache.
