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 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
 * 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.
