Victoria RDO Release Announcement
by Amy Marrich 16 Nov '20

16 Nov '20

If you're having trouble with the formatting, this release announcement is available online https://blogs.rdoproject.org/2020/11/rdo-victoria-released/ --- RDO Victoria Released The RDO community is pleased to announce the general availability of the RDO build for OpenStack Victoria for RPM-based distributions, CentOS Linux and Red Hat Enterprise Linux. RDO is suitable for building private, public, and hybrid clouds. Victoria is the 22nd release from the OpenStack project, which is the work of more than 1,000 contributors from around the world. The release is already available on the CentOS mirror network at http://mirror.centos.org/centos/8/cloud/x86_64/openstack-victoria/. The RDO community project curates, packages, builds, tests and maintains a complete OpenStack component set for RHEL and CentOS Linux and is a member of the CentOS Cloud Infrastructure SIG. The Cloud Infrastructure SIG focuses on delivering a great user experience for CentOS Linux users looking to build and maintain their own on-premise, public or hybrid clouds. All work on RDO and on the downstream release, Red Hat OpenStack Platform, is 100% open source, with all code changes going upstream first. PLEASE NOTE: RDO Victoria provides packages for CentOS8 and python 3 only. Please use the Train release, for CentOS7 and python 2.7. Interesting things in the Victoria release include: - With the Victoria release, source tarballs are validated using the upstream GPG signature. This certifies that the source is identical to what is released upstream and ensures the integrity of the packaged source code. - With the Victoria release, openvswitch/ovn are not shipped as part of RDO. Instead RDO relies on builds from the CentOS NFV SIG. - Some new packages have been added to RDO during the Victoria release: - ansible-collections-openstack: This package includes OpenStack modules and plugins which are supported by the OpenStack community to help with the management of OpenStack infrastructure. - ansible-tripleo-ipa-server: This package contains Ansible for configuring the FreeIPA server for TripleO. - python-ibmcclient: This package contains the python library to communicate with HUAWEI iBMC based systems. - puppet-powerflex: This package contains the puppet module needed to deploy PowerFlex with TripleO. - The following packages have been retired from the RDO OpenStack distribution in the Victoria release: - The Congress project, an open policy framework for the cloud, has been retired upstream and from the RDO project in the Victoria release. - neutron-fwaas, the Firewall as a Service driver for neutron, is no longer maintained and has been removed from RDO. Other highlights of the broader upstream OpenStack project may be read via https://releases.openstack.org/victoria/highlights. Contributors During the Victoria cycle, we saw the following new RDO contributors: Amy Marrich (spotz) Daniel Pawlik Douglas Mendizábal Lance Bragstad Martin Chacon Piza Paul Leimer Pooja Jadhav Qianbiao NG Rajini Karthik Sandeep Yadav Sergii Golovatiuk Steve Baker Welcome to all of you and Thank You So Much for participating! But we wouldn’t want to overlook anyone. A super massive Thank You to all 58 contributors who participated in producing this release. This list includes commits to rdo-packages, rdo-infra, and redhat-website repositories: Adam Kimball Ade Lee Alan Pevec Alex Schultz Alfredo Moralejo Amol Kahat Amy Marrich (spotz) Arx Cruz Bhagyashri Shewale Bogdan Dobrelya Cédric Jeanneret Chandan Kumar Damien Ciabrini Daniel Pawlik Dmitry Tantsur Douglas Mendizábal Emilien Macchi Eric Harney Francesco Pantano Gabriele Cerami Gael Chamoulaud Gorka Eguileor Grzegorz Grasza Harald Jensås Iury Gregory Melo Ferreira Jakub Libosvar Javier Pena Joel Capitao Jon Schlueter Lance Bragstad Lon Hohberger Luigi Toscano Marios Andreou Martin Chacon Piza Mathieu Bultel Matthias Runge Michele Baldessari Mike Turek Nicolas Hicher Paul Leimer Pooja Jadhav Qianbiao.NG Rabi Mishra Rafael Folco Rain Leander Rajini Karthik Riccardo Pittau Ronelle Landy Sagi Shnaidman Sandeep Yadav Sergii Golovatiuk Slawek Kaplonski Soniya Vyas Sorin Sbarnea Steve Baker Tobias Urdin Wes Hayutin Yatin Karel The Next Release Cycle At the end of one release, focus shifts immediately to the next release i.e Wallaby. Get Started There are three ways to get started with RDO. To spin up a proof of concept cloud, quickly, and on limited hardware, try an All-In-One Packstack installation. You can run RDO on a single node to get a feel for how it works. For a production deployment of RDO, use TripleO and you’ll be running a production cloud in short order. Finally, for those that don’t have any hardware or physical resources, there’s the OpenStack Global Passport Program. This is a collaborative effort between OpenStack public cloud providers to let you experience the freedom, performance and interoperability of open source infrastructure. You can quickly and easily gain access to OpenStack infrastructure via trial programs from participating OpenStack public cloud providers around the world. Get Help The RDO Project has our users(a)lists.rdoproject.org for RDO-specific users and operators. For more developer-oriented content we recommend joining the dev(a)lists.rdoproject.org mailing list. Remember to post a brief introduction about yourself and your RDO story. The mailing lists archives are all available at https://mail.rdoproject.org. You can also find extensive documentation on RDOproject.org. The #rdo channel on Freenode IRC is also an excellent place to find and give help. We also welcome comments and requests on the CentOS devel mailing list and the CentOS and TripleO IRC channels (#centos, #centos-devel, and #tripleo on irc.freenode.net) however we have a more focused audience within the RDO venues. Get Involved To get involved in the OpenStack RPM packaging effort, check out the RDO contribute pages, peruse the CentOS Cloud SIG page, and inhale the RDO packaging documentation. Join us in #rdo and #tripleo on the Freenode IRC network and follow us on Twitter @RDOCommunity. You can also find us on Facebook and YouTube.

CloudKitty deployment on Train and/or Ussuri
by Thode Jocelyn 16 Nov '20

16 Nov '20

Hi, I was looking at the possibilities to have Rating-as-A-Service in our Openstack (currently train but planning to move to Ussuri) and I stumbled upon CloudKitty. I'm currently facing multiple issues with cloudkitty itself and with openstack-ansible. (We are using a containerized deployment with LXC) * I noticed that openstack-ansible has no playbook yet to install a service like CloudKitty even though starting from Ussuri it was added in the ansible-role-requirements.yml. I have created a small patch to be able to install CloudKitty via openstack-ansible and if this is of interest I could potentially submit a PR with this. * The os_cloudkitty role seems to kinda work and only with a relatively old version of CloudKitty. For example, here : https://opendev.org/openstack/openstack-ansible-os_cloudkitty/src/branch/st… since CloudKitty v8.0.0 the section should be named "[fetcher_keystone]", but I found no information as to which CloudKitty version should be used with this role. Does someone have any recommendation as to which version should be used and if there is any interest in improving the role to support more recent versions of CloudKitty? * Even when tweaking the configuration and installing v7.0.0 of Cloudkitty it only fixes cloudkitty-processor, I was never able to make cloudkitty-api work I always get an error like "Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings'". Any input on this would be greatly appreciated. Cheers Jocelyn

[nova] MessageUndeliverable from nova-conductor and MessagingTimeout from nova-compute
by Tony Liu 16 Nov '20

16 Nov '20

It's not about connection, but message transmitting. Title is changed. I am having rabbitmq 3.8.4 and nova 21.0.0. When I check rabbitmq queues for compute, I see 3 messages in compute.compute-1 and 0 messages in other compute node queues. In nova-conductor log of all 3 instances, I see "oslo_messaging.exceptions.MessageUndeliverable". In nova-compute log on compute-1, I see "Timed out waiting for nova-conductor." Actually, 4 out of 5 compute nodes have such warning. One compute node has exception "oslo_messaging.exceptions.MessagingTimeout". "rabbitmqctl list_bindings | grep compute-1" shows this. ================================= exchange compute.compute-1 queue compute.compute-1 [] nova exchange compute.compute-1 queue compute.compute-1 [] ================================= Is this some known issue? How did it happen? What's the cause of it and any way to prevent it from happening? Thanks!

Where to send mascot graphic adjustment proposals
by Michael Chapman 16 Nov '20

16 Nov '20

While doing some work on the designate docs I wanted to replace the logo on the diagrams (for example https://docs.openstack.org/designate/latest/contributor/architecture.html) with the mascot graphics available, specifically the horizontal one here: https://object-storage-ca-ymq-1.vexxhost.net/swift/v1/6e4619c416ff4bd19e1c0… The bottom line of the crocodile is just slightly not aligned with the text, which I think could be improved, and perhaps the crocodile could also be increased in size to match that of the text. In addition, the bottom of the mascots page mentions to contact anne(a)openstack.org which is no longer an active address. Are the above proposed changes reasonable, and is there a new contact available for getting mascot graphics modified? I can change it in the designate diagrams myself but they are marked ND so I don't think that's technically allowed. - Michael

Which deployment method for ceph (rook|ceph-ansible|tripleo)
by Oliver Weinmann 16 Nov '20

16 Nov '20

Hi, I'm still in the process of preparing a OpenStack POC. I'm 100% sure that I want to use CEPH and so I purchased the book Mastering CEPH 2nd edition. First of all, It's a really good book. It basically explains the various methods how ceph can be deployed and also the components that CEPH is build of. So I played around a lot with ceph-ansible and rook in my virtualbox environment. I also started to play with tripleo ceph deployment, although I haven't had the time yet to sucessfully deploy a openstack cluster with CEPH. Now I'm wondering, which of these 3 methods should I use? rook ceph-ansible tripleo I also want to use CEPH for NFS and CIFS (Samba) as we have plenty of VMs running under vSphere that currently consume storage from a ZFS storage via CIFS and NFS. I don't know if rook can be used for this. I have the feeling that it is purely meant to be used for kubernetes? And If I would like to have CIFS and NFS maybe tripleo is not capable of enabling these features in CEPH? So I would be left with ceph-ansible? Any suggestions are very welcome. Best Regards, Oliver

[masakari] Teams cleanup
by Radosław Piliszek 15 Nov '20

15 Nov '20

Hello Everyone! To avoid the ghost town effect in Masakari teams, I propose to clean up the memberships. I've already had a chance to discuss it with Takashi Kajinami on IRC [0] as he wanted to remove himself. We have 3 teams (1 gerrit, 2 launchpad): - Gerrit masakari-core [1] - Launchpad masakari-drivers [2] - Launchpad masakari-bugs [3] I plan to set these to the following people: - myself [Radosław Piliszek] (the new PTL) - suzhengwei (new active contributor and core) - Jegor van Opdorp (new active contributor and core) - Sampath Priyankara (the previous PTL) - Tushar Patil (the previously most active core) I will enact the change in a week from now if there are no objections. I also see a few issues likely to discuss with the infra team: 1) Launchpad masakari-drivers - there is a pending invitation for the release team - I doubt it has much use but I would love to see it accepted/rejected/accepted&removed. 2) Gerrit masakari-core - there is an external CI in the core team - why would it need this level of privilege? It does not add its flags to changes, only replies with job status. [0] http://eavesdrop.openstack.org/irclogs/%23openstack-masakari/%23openstack-m… [1] masakari-core: https://review.opendev.org/#/admin/groups/1448,members [2] https://launchpad.net/~masakari-drivers/+members [3] https://launchpad.net/~masakari-bugs/+members Kind regards, -yoctozepto
