** Description changed: The juju team is requesting an FFE for juju-core. Juju2 represents API changes and new features and bugfixes for juju. We are NOT requesting a place on any image for xenial. This FFE is intended to cover the acceptance of the updated juju-core package, as well as the new package juju-core-1.25, which is a new version of the existing juju-core package allowing the existing juju1 binary to be installed. Related FFes ------------ Required for Juju 2.0: juju-mongodb3.2: bug 1557852 juju-mongodb2.6: bug 1557830 juju-mongo-tools3.2: bug 1558336 Required consumers: conjure: bug 1561037 bigdata: bug 1561043 - openstack: ?TBC + openstack: Already in universe, dep wait on conjure -> juju 2.0 charm-tools: bug 1546776 User-Facing Features / Changes ------------------------------ * New Terminology * Command Name Changes * New Juju home directory * Multi-Model Support Active by Default * New Bootstrap and Cloud Management Experience * Native Support for Charm Bundles * Multi Series Charms * Improved Local Charm Deployment * LXC Local Provider No Longer Available * LXD Provider * LXD Containers * Microsoft Azure Resource Manager Provider * Bootstrap Constraints, Series * Juju Logging Improvements * Unit Agent Improvements * API Login with Macaroons * MAAS Spaces * Resources * Juju Status Improvements * Relation Get and Set Compatibility * Support for new AWS M4 Instance Types * Support for win10 and win2016 The full list of changes can be found here: https://lists.ubuntu.com/archives/juju/2016-March/006922.html and in the final release notes. Timeline -------- We have released 2 alphas, and 3 betas for juju2 so far, in addition 3 alpha builds of 1.26 which became 2.0. All targeted 2.0 features are now implemented, and we anticipate releasing one release candidate before a final stable build. Juju missed uploading any versions of 2.0 to the archive itself, as well as the initial projected date of having beta1 in xenial before feature freeze. However, juju has been released regularly during the development cycle inside the juju ppa. You can see the details on the delivered features and milestones on https://launchpad.net/juju-core/2.0. The final stable build will be ready in time for the xenial release. Upgrades -------- Users upgrading from trusty will find their juju version updated. The current juju-core package will be provided as juju-1.25. Update-alternatives will provide support for toggling /usr/bin/juju between juju-1.25 and juju-2.0 binaries. We have tested to ensure the intended behavior occurs for the following scenarios: New Xenial: No juju, apt-get install juju, juju version will be 2.0. Example using ppa: <http://paste.ubuntu.com/15555629/> Upgrading Trusty/Wily/old Xenial: Already installed juju 1.X, upgraded to latest 1.25.4, 2.0 also installed and is the default juju, update-alternatives used to switch between the two. Example using ppa: <http://paste.ubuntu.com/15555663/> Risks ----- Although juju itself is now feature complete for 2.0, the MAAS 2.0 support will require additional work to be fully supported. MAAS 2.0 is currently under development as well, and is an alpha3 at the time of this writing. Juju will need to add support for the final version of MAAS 2.0, and this is a risk of occurring after xenial is released. If so, we expect to release an sru for juju-core soon after xenial releases to provide this support. Quality / Testing ----------------- As this version breaks API with 1.0, testing for features regressions as well as fixing old bugs and avoiding new bugs has been important. The juju team and the greater juju community has been testing 2.0 to ensure it’s stable and ready to support all of the 1.0 workloads in addition to making use of the new 2.0 features. In comparison to juju-1.25: * Tests improvements including * MAAS testing improved * Container networking * 9 non-voting tests are now voting * New tests for all 2.0 features * Powerpc toolchain is vastly improved * No test regressions! * S390 builds reliably, is fully tested and is treated the same as other supported architectures * 114 bugs has been fixed Juju practices continuous integration and testing of the juju source tree. All voting tests must pass for ubuntu before release. For example, for beta3, you can see all tests are passing on ubuntu. The full details are here: http://reports.vapour.ws/releases/3815. The community has also been actively involved with testing, providing feedback, and adopting 2.0 throughout the development cycle. * 250 bugs and wishlist items filed * 4 bugs fixed by community members * ~100-125 downloads for each ppa release Community Adoption ------------------ The community has already begun adopting 2.0, and is dependent upon 2.0 being inside xenial. * Multiple external customers are depending on 2.0 inside xenial * Charm store fully supports 2.0 features * Community charmers * Gitlab, openstack and other charms already are using 2.0 features * Many other charms are dependent upon multi-model/controller features * Public demo and feedback sessions @ charmers summit * Public talks accepted for discussing juju 2.0 at conferences * 2 packages (conjure, bigdata) currently in the upload queue have been built and depend upon the new version of juju 2.0. Packaging --------- The security team has requested changes to the current juju packaging with the ultimate goal of breaking out the embedded non-juju golang dependencies. As part of this FFE, the juju-core package depends upon all currently packaged golang depends that are already in the archive. The remaining ~15 dependencies have been packaged and will be uploaded to the archive once the archive has opened again for Y development. We will not be attempting to add these additional packages as part of this FFE.
