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


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
 * 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):


For HP Cloud the public bucket is available at:


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.
