DevOps WG Update (03-06-19)

Several User Stories currently being worked in current sprint.

  • Applications Functions SDK - build automation completed - pending approval / merge.
  • Demo last week Concourse CI semver approach for release versioning (i.e. tagging) go modules
    Thank you Jacob Blain Christen (Intel)
  • Work in progress to demonstrate build automation using the approach.
  • Risk: Landing of the EdgeX TIG stack infrastructure still pending - LF dependency
  • Risk: Sigul is being positioned to be used for signing release artifacts using Jenkins EdgeX build automation. This is Linux Foundation tooling. Additional work has been identified that requires sigul to be enhanced to enable signing of git tags and Docker images. This work was not scoped for Edinburgh. Help Needed from Linux Foundation / developer resources
  • New Scope for Performance testing - build automation has not started

Mail List / Calendar Updates

Brett Preston

edgexfoundry.org | @edgexfoundry

Changes coming to mail lists / calendaring

Current status: All meeting scheduling, calendar invites, mail list management is dependent on one person.

Forward thinking: WG Chairs will be enabled to execute all of the above via self-service tools; while still having full access to PM for support. Akraino successfully migrated to this model a few months back and they now have 20 hosts on-boarded (reference https://wiki.akraino.org/pages/viewpage.action?pageId=6128052).

Google vs Outlook challenges no more: The new calendaring model accurately sends out updates when meeting(s) are modified.

Next Steps:

  • Meeting invitees will be provided instructions on how to subscribe to a meeting series (options via either Groups.io or Confluence/Wiki dependent on preference). Reminders will be sent out over the coming weeks across multiple modes of communication, including Brett joining WG calls to help walk through the process. Gmail invites will be kept up for 1 month, giving plenty of time for folks to subscribe to the calendar invites, at which point they will be removed/sunset. Note: Dial-in information does not change during this process.
  • WG Chairs/Meeting Hosts will be provided Zoom log in and Groups.io Moderator status to allow them to both schedule new meetings and distribute invites to all on a particular mail list.
  • Those looking to jump right in can do so, with information already up at https://wiki.edgexfoundry.org/pages/viewpage.action?pageId=21824127
