Notes

• Brainstorming – Jeff Terstriep to present/discuss/compare a more CMS-based approach for the NDS Explorer app.

  Jira
  server NCSA Jira key NDS-24

  • Looked at the Plone CMS system being used by CyberGIS
  • Similiaries/overlap with what Django packages can provide for Django
  • Has web GUI for defining model (data)
  • Uses Zope DB by default, but can use postgres, etc.
  • Seems to overlap with wikis more than NDS Explorer – although Jeff is using Plone to launch and view results of processing being run on Amazon EC2 (input parms and results stored in Plone models)
  • Different than wikis in that Plone can have multiple templates/skins/styles (i.e. presentations) in front of the same model data
  • NCSA does not have an institutionally supported Plone server
  • Perhaps more relevant to the NDS Dashboard than the NDS Explorer
  • Not planning on using this for NDS Explorer
  • Unknown User (mfelarca) will review tools/libraries for the web services app at the developer meeting on Wednesday
    • functionality needed includes REST API/impl generation support and authn/z
  • 6/25 discussion
    • tentative direction is the MEAN stack – mongodb, express, angular.js, node.js
    • also loopback
      
      • from github: LoopBack is an open source Node.js framework built on top of Express optimized for building APIs for mobile, web, and other devices.
    • no problem calling the python OpenStack APIs
      
    • focus is getting alpha1 up and running quickly
  • 6/26 more general discussion
    • how we will be calling the python nova apis from our web services implementation?
      
  • 7/6: Lengyue Chen reviewed the StrongLoop tool for the team
    • Command line and GUI for defining REST API and for generating implementation code, including database DDL
      
    • How does ongoing maintenance work?  Does tool support "migrations" in a way similar to Django?
    • Lengyue Chen currently working to get the JS-to-python calls working
  • 7/7: Lengyue Chen reports working now
    • Lengyue Chen will commit to repository (after hg/git resolved by Mario – see below)
      
  •  7/8: Initial codebase is committed.  Work now transitioned and proceeding under NDS-25 and NDS-2 so will close this ticket.

    • 7/10: "create ndslabs" functionality is working
      
    • Unknown User (mfelarca) will rename/redefine bitbucket hg repository yt-webapp to nds-web-services
    • the name of the nds-explorer repository does not change (this is the web user interface)
    • will be done by Monday 6/29
    • Goals for next week (week of 6/29-7/2) are

        • includes the "scaffolding" for our MEAN stack
    • 7/6: Not done
    • 7/7: initial repo created, but using git. 
      • Not yet pushed to the repo – problem with the code repository on the ubuntu workstation
      • Unknown User (mfelarca)
      will convert it to mercurial.7/8: Unknown User (mfelarca) converted the repo to mercurial.  This ticket is now completed.
      • and Lengyue Chen will resolve local repo issue and commit/push to bitbucket
        
        

  • Jira
    server NCSA Jira key NDS-2

    • Goals for next week (week of 6/29-7/2) are
      • first two pieces of functionality working end-to-end – from brower to explorer to web service to backend systems (openstack)
        • list environments
        • create environment
    • 7/6: In progress
    • 7/7: In progress

    • Unknown User (mfelarca) will demo existing web app at the developer meeting on Friday 6/26
      
    • 6/26 discussion
      • old app up and running on mario's dev system 
      • not connecting to yt-webapp
      • working with kacper on connectivity to yt-webapp problem
    • 7/6: No report
    • 7/7: discussed
      • demo at SC14 – not at NDS3 Austin – explains repository dates
      • nds-explorer to yt-webapp (rest2) pulling in ythub-workers (v1)
      • Unknown User (mfreemon) will look at as well
      • important to understand current state
    • 7/8: not discussed

  ...

  • • 7/10: Unknown User (mfreemon) has made significant progress and expects to post to the wiki in the next couple of business days
      
      
  • General NDS Explorer / NDS Web Services Design/Implementation Topics
    • NDS Explorer Design and Implementation
    • 6/22 No decision yet on how to store Environment or Service definition information
    • 6/26 discussion
      
      • use mongodb for store environment information
      • use flat file (not mongo) for service definitions – format of flat file to be proposed by Unknown User (mfelarca)
        • note previous input: ... having service definitions that can be expressed as JSON would be ideal, since that's readily and easily parseable (and constructable) in a fully client-side app.
          
          
  • General OpenStack Topics
    
    • 7/6 discussion
      
      • Patrick Mulrooney brought up alternative approaches for interfacing with OpenStack management functionality (what we're calling the management node), and SDSC plans.  Patrick will follow up on the mailing list with links for future reading. 
      • libvirt docker (link?) was also discussed as a potential mechanism to run docker containers without needing CoreOS (thus simplifying the runtime environment).
    • 7/7
      • (prior to 7/7 meeting) Patrick Mulrooney provided API link and openstack component diagram at SDSC
        
        • http://docs.openstack.org/user-guide/common/cli_overview.html
          
      • We will discuss next time, but Unknown User (mfreemon) sees a lot of consistency between the OpenStack deployments at NCSA and SDSC
    • 7/10
      • Unknown User (mfreemon) mentions that the production OpenStack cluster at NCSA (nebula) is going into friendly user mode – more details on the discuss list as they become available
        
      • Patrick Mulrooney asks: What verison of OpenStack is nebula?
      • Unknown User (mfreemon) will find out
        • Answer: Kilo
          
          
  • Other
    • Jeff Terstriep suggests a discussion of role of VMs and docker as a future topic (perhaps Fri 7/17)
