15 Oct '21

Hi everyone, The next vPTG will be held on 18-22 October as I shared at the previous IRC meeting [1]. Registration has already opened [2]. We've decided to have the next vPTG session on the same timeslots, 6-8 UTC, as previous for most of us join from India and APAC regions. I've prepared etherpad for the next vPTG [3]. If you have any suggestion, please add your topic on it.

[dev][cinder] Consultation about new cinder-backup features
by Daniel de Oliveira Pereira 14 Oct '21

14 Oct '21

Hello everyone, We have prototyped some new features on Cinder for our clients, and we think that they are nice features and good candidates to be part of upstream Cinder, so we would like to get feedback from OpenStack community about these features and if you would be willing to accept them in upstream OpenStack. Our team implemented the following features for cinder-backup service: 1. A multi-backend backup driver, that allow OpenStack users to choose, via API/CLI/Horizon, which backup driver (Ceph or NFS, in our prototype) will be used during a backup operation to create a new volume backup. 2. An improved NFS backup driver, that allow OpenStack users to back up their volumes to private NFS servers, providing the NFS hostpath at runtime via API/CLI/Horizon, while creating the volume backup. Considering that cinder was configured to use the multi-backend backup driver, this is how it works: During a volume backup operation, the user provides a "location" parameter to indicate which backend will be used, and the backup hostpath, if applicable (for NFS driver), to create the volume backup. For instance: - Creating a backup using Ceph backend: $ openstack volume backup create --name <backup_name> --location ceph <volume_id> - Creating a backup using the improved NFS backend: $ openstack volume backup create --name <backup_name> --location nfs://my.nfs.server:/backups <volume_id> If the user chooses Ceph backend, the Ceph driver will be used to create the backup. If the user chooses the NFS backend, the improved NFS driver, previously mentioned, will be used to create the backup. The backup location, if provided, is stored on Cinder database, and can be seen fetching the backup details: $ openstack volume backup show <backup_name> Briefly, this is how the features were implemented: - Cinder API was updated to add an optional location parameter to "create backup" method. Horizon, and OpenStack and Cinder CLIs were updated accordingly, to handle the new parameter. - Cinder backup controller was updated to handle the backup location parameter, and a validator for the parameter was implemented using the oslo config library. - Cinder backup object model was updated to add a nullable location property, so that the backup location could be stored on cinder database. - a new backup driver base class, that extends BackupDriver and accepts a backup context object, was implemented to handle the backup configuration provided at runtime by the user. This new backup base class requires that the concrete drivers implement a method to validate the backup context (similar to BackupDriver.check_for_setup_error) - the 2 new backup drivers, previously mentioned, were implemented using these new backup base class. - in BackupManager class, the "service" attribute, that on upstream OpenStack holds the backup driver class name, was re-implemented as a factory function that accepts a backup context object and return an instance of a backup driver, according to the backup driver configured on cinder.conf file and the backup context provided at runtime by the user. - All the backup operations continue working as usual. Could you please let us know your thoughts about these features and if you would be open to adding them to upstream Cinder? If yes, we would be willing to submit the specs and work on the upstream implementation, if they are approved. Regards, Daniel Pereira

by Thomas Goirand 04 Oct '21

04 Oct '21

Hi, As you may know, eventlet is incompatible with dnspython >= 2.0.0.0rc1. See [1] for the details. However, Debian unstable has 2.0.0. Would there be some good soul willing to help me fix this situation? I would need a patch to fix this, but I'm really not sure how to start. Cheers, Thomas Goirand (zigo)

[neutron][ovn] support for stateless NAT for floating ip in ml2 ovn
by Moshe Levi 26 Sep '21

26 Sep '21

Hi all, OVN support stateless NAT operations [1] for use case of 1:1 mapped between inner and external ips, i.e dnat_and_snat rule. In openstack is the floating ip use-case. Looking on ml2 ovn support it seem that it only support floating ip with connection tracking. Can ml2 ovn support also the stateless NAT option? Is there concerns using stateless NAT?

Edge for scientific research session on September 13 Edge WG meeting
by Ildiko Vancsa 18 Sep '21

18 Sep '21

Hi, I’m very excited to invite you to a session with the Chameleon project to discuss how edge computing is powering education, scientific research and more! As always in the area of edge there are challenges and gaps that we need to solve together. In that sense the session will start with a presentation that we will then turn into a discussion to turn towards discussing solutions. Please also note that the Chameleon project is using OpenStack to build edge solutions. As they identified some gaps they would like to work with the community to address the challenges that they’ve been hitting. Please join us to get their feedback and find the best way to improve OpenStack to deliver a platform that can be used on the edge! The session will take place on the OpenInfra Edge Computing Group weekly call on __September 13, at 1300 UTC / 6am Pacific__. For the latest dial-in information please refer to this page: https://wiki.openstack.org/wiki/Edge_Computing_Group#Meetings Please find the details of the session below. Thanks and Best Regards, Ildikó Title: Chameleon: a cloud to edge infrastructure for science Abstract: The NSF-funded Chameleon project (www.chameleoncloud.org) provides an OpenStack-based bare metal reconfigurable cloud that supports systems research, education, and emergent application projects in science. The facility has been in existence for 6+ years, and has served ~6,000 users working on a variety of projects ranging from networking, operating systems design, and security, to innovative applications in astronomy, physics, and life sciences. Recent research trends in IoT and edge computing, as evidenced by increased numbers of project applications in those areas, made it clear that Chameleon needed to expand into the edge space. Remaining within the OpenStack framework allowed us to leverage end-user features that we developed for Chameleon, such as access via federated identity and Jupyter integration. Accordingly, we developed infrastructure called CHI@Edge that adapts Zun to provision containers on edge devices and significantly expands its capabilities to work in the edge space. The talk will describe our use case and the emergent product definition, the OpenStack adaptations we made to the current preview implementation, the directions we plan to take in our further work, as well as the ecosystem of projects and NSF infrastructure deployments leveraging this work and collaborating with us.

[all]Introduction to venus which is the project of log management and has been contributed to the OpenStack community
by Liye Pang(逄立业) 10 Sep '21

10 Sep '21

Hello everyone, after feedback from a large number of operations and maintenance personnel in InCloud OpenStack, we developed the log management project “Venus” for the OpenStack projects and that has contributed to the OpenStack community. The following is an introduction to “Venus”. If there is interest in the community, we are interested in proposing it to become an official OpenStack project in the future. Background In the day-to-day operation and maintenance of large-scale cloud platform, the following problems are encountered： l Time-consuming for log querying while the server increasing to thousands. l Difficult to retrieve logs, since there are many modules in the platform, e.g. systems service, compute, storage, network and other platform services. l The large amount and dispersion of log make faults are difficult to be discovered. l Because of distributed and interaction between components of the cloud platform, and scattered logs between components, it will take more time to locate problems. About Venus According to the key requirements of OpenStack in log storage, retrieval, analysis and so on, we introduced Venus project, a unified log management module. This module can provide a one-stop solution to log collection, cleaning, indexing, analysis, alarm, visualization, report generation and other needs, which involves helping operator or maintainer to quickly solve retrieve problems, grasp the operational health of the platform, and improve the management capabilities of the cloud platform. Additionally, this module plans to use machine learning algorithms to quickly locate IT failures and root causes, and improve operation and maintenance efficiency. Application scenario Venus played a key role in the following scenarios： l Retrieval: Provide a simple and easy-to-use way to retrieve all log and the context. l Analysis: Realize log association, field value statistics, and provide multi-scene and multi-dimensional visual analysis reports. l Alerts：Convert retrieval into active alerts to realize the error finding in massive logs. l Issue location: Establish a chain relationship and knowledge graphs to quickly locate problems. Overall structure The architecture of log management system based on Venus and elastic search is as follows: Diagram 0: Architecture of Venus venus_api: API module，provide API、rest-api service. venus_manager: Internal timing task module to realize the core functions of the log system. Current progress The current progress of the Venus project is as follows: l Collection：Develop fluentd collection tasks based on collectd to read, filter, format and send plug-ins for OpenStack, operating systems, and platform services, etc. l Index：Dealing with multi-dimensional index data in elasticsearch, and provide more concise and comprehensive authentication interface to return query results. l Analysis：Analyzing and display the related module errors, Mariadb connection errors, and Rabbitmq connection errors. l Alerts：Develop alarm task code to set threshold for the number of error logs of different modules at different times, and provides alarm services and notification services. l Location：Develop the call chain analysis function based on global_requested series, which can show the execution sequence, time and error information, etc., and provide the export operation. l Management：Develop configuration management functions in the log system, such as alarm threshold setting, timing task management, and log saving time setting, etc. Application examples Two examples of Venus application scenarios are as follows. 1. The virtual machine creation operation was performed on the cloud platform and it was found that the virtual machine was not created successfully. First, we can find the request id of the operation and jump to the virtual machine creation call chain page. Then, we can query the calling process, view and download the details of the log of the call. 2. In the cloud platform, the error log of each module can be converted into alarms to remind the users. Further, we can retrieve the details of the error log and error log statistics. Next step The next step of the Venus project is as follows: * Collection：In addition to fluent, other collection plugins such as logstash will be integrated. * Analysis: Explore more operation and maintenance scenarios, and conduct statistical analysis and alarm on key data. * display: The configuration, analysis and alarm of Venus will be integrated into horizon in the form of plugin. * location: Form clustering log and construct knowledge map, and integrate algorithm class library to locate the root cause of the fault.
