Day 2 (2021-07-06)

  • Interest in being able to handle content already in S3/Swift content
  • DURACLOUD-1316
    • Interest:
      • Andy - definite interest, but it'll be challenging to ensure everything works.
      • How do we prevent overwrites (or simultaneous writes)?
        • Perhaps some type of locking mechanism?
        • Could have a toggle that only allows writes via either S3 or DuraCloud API
      • S3 does provide a way to send SNS notifications when content lands. Could use this to add a message to the SQS monitored by the Mill
      • Fedora has a similar need to allow direct writes to OCFL then notifying Fedora
      • Would need a way to ensure we get checksums properly and that the manifest/audit logs
        • Would need to validate
  • Top priorities
    • Andy: 1258 is important, Mill using quite an old version. 1257 is essentially done.
    • Danny: 1290 (docker/terraform), setting us up for long-term maintenance
    • Nick: Snapshot totals (most questions), 1150, 1279, 1301
    • Bill: Snapshot totals
  • Plans for this week
    • Andy: 1257, 1258, 1290
    • Nick: 1069, 1268
    • Danny: 1290
    • Bill: 1292, 1278
  • Github Actions
    • In DuraCloud, we only merge to master on release
    • The push to sonatype can push it all the way through
    • Most projects tend to use tags
  • Should we consider changing our branch structure? Have master being the leading edge?
    • One option: develop → main and master → release
    • It's helpful to have a branch where we're able to merge everything in and do testing
    • Rename master to main? 
    • Develop: The integration point for development
    • Master/Main: Merges from develop after testing (usually a release)

Day 4 (2021-07-08)

  • Status
    • Bill: 1316 and 1292
    • Danny: 
      • Nick brought up issue on the Mill. Danny added fix PR, has been merged.
      • Focused on Terraform/Docker for the Mill. It's coming along
        • Plan to have one Dockerfile in the mill that will get built and pushed on release. Will include all the java jars related to the mill. A script will run the type of node that we want.
        • A configuration setting (node type) will be passed in to say what that node will do
        • Will also be an AWS bucket that includes all the mill configuration
        • Outside of the docker container the mounting for EFS will be handled. Terraform will handle mounting EFS and set up the path mapping.
        • There will be a script to push to dockerhub, creating the image with Github Actions
    • Nick:
      • Working on 1268, Retrieval Tool failing.
        • Preferred solution: When dealing with files list, get the space manifest
    • Andy
      • Made a token start on updating the methods for the mill
  • Topics
    • Make the move from master to main - Action for Bill
      • Check on whether there can be a symlink? Are these auto-forwarded?
    • Github actions to push release artifacts should work off of tags (rather than merges to main)

Day 7 (2021-07-13)

  • Status
    • Danny:
      • Have a docker container working for the workman piece of the Mill
      • Structure in place for running the various node types
      • Will continue to use cloud-init for launch
        • The program will be invoked by terraform, passing in user parameters, which will generate the cloud-init scripts
        • Terraform will generate the auto-scaling groups
        • cloud-init has been pared down considerably (attach EFS, run docker)
        • Each node type will run have a distinct cloud-init
      • Within the docker container there will be scripts based on the node type
      • Most of the work so far has been in the mill project, will push so Andy can take a look
        • Feedback welcome!
      • Should be able to run the Docker container independently (locally)
    • Andy
      • Crossed off 1257 and 1258
      • Picking up 1304
      • Can't make Thursday call
      • Mohana focused elsewhere - not much traction on DuraCloud
    • Nick
      • PR for 1268 in progress (Retrieval Tool for list file)
        • Probably worth adding a comment in the docs to say how it handles
      • 1069 in process
        • Looking at an approach
      • 1150 also in process - snapshot totals in the Bridge API
        • Do we need to have a client parameter
    • Bill
      • Continued work on dependencies - 1292
