juju-core 1.11.0

juju-core 1.11.0
================

A new release of Juju, juju-core 1.11.0, is now available for testing.

Getting Juju
------------

The location of the PPA has changed, please note the new location.

juju-core 1.11.0 is available from the Juju development PPA

https://launchpad.net/~juju/+archive/devel

New and Notable
---------------

 * Support for plugins has been added to the Juju cli command. Similar to git plugins, calling juju something, if not a built in command, will search your $PATH for juju-something.
 * Keypass authentication is now supported when connecting to Openstack environments.
 * A new metadata format is used to describe the available image ids matching a given series and architecture (see lp:simplestreams). For EC2 environments, this data is located at http://cloud-images.ubuntu.com/releases/streams/v1/. For Openstack environments, the data is found in the environment’s shared public bucket.
 * The use of constraints to specify the instance characteristics is now supported for Openstack environments. The supported constraints are: mem, arch, cpu-cores.
 * The use of “default-image-id” and “default-instance-type” environment configuration keys for Openstack environments are no longer required and are ignored. The correct instance type to run is determined using constraints. The correct image to run is determined from simplestreams based image metadata. For Canonistack region lcy01, published metadata is used out-of-the-box, so long as the public bucket is correctly configured (see testing notes below). For other Openstack environments, a tool is provided which can be run to generate metadata files, which need to be copied to the environment’s public bucket. Run “juju help image-metadata” for details.
An issue with the relation list hook command returning incompatible data has been fixed. lp #1182224
 * EC2_* style Amazon environment variables for specifying credentials for EC2 environments are now supported. lp # 1174874

Configuration changes
---------------------

 * The use of “default-image-id” and “default-instance-type” environment configuration keys for Openstack environments are no longer required and are ignored.

Testing on Canonistack and HP Cloud
-----------------------------------

A publicly readable bucket has been created for holding the Juju tools on Canonistack. To use it, put this in your ~/.juju/environments.yaml (all on one line):

     public-bucket-url: https://swift.canonistack.canonical.com/v1/AUTH_526ad877f3e3464589dc1145dfeaac60

For HP Cloud the public bucket is available at:

     public-bucket-url: https://region-a.geo-1.objects.hpcloudsvc.com/v1/60502529753910

As an unstable release we do not yet guarantee a clean upgrade path of running environments from on 1.11.x version to another. However, live-upgrades may work now, and will be a supported feature of 2.0.

We encourage everyone to subscribe the mailing list at juju-dev@lists.canonical.com, or join us on #juju-dev on freenode.
