Migrating to Storyboard

If your project is thinking about migrating to Storyboard or has recently migrated to Storyboard, the following will help you get started.

Planning to Migrate

So you want to migrate...

  • Talk to the storyboard team to see if your project is ready i.e. isn't heavily dependent on other projects, migrates into a test environment cleanly, etc. The #storyboard channel is a good place to start this conversation. We have regular meetings for you to drop into as well
  • Once it's been decided that you can migrate cleanly, pick a date to make the change and in the interim, try to close as many bugs as possible
  • If you want to run your own test migration, those directions can be found below in the 'Test Migration' Section

Test Migration

  1. Obtain a StoryBoard instance

    First you'll need superuser permissions on a StoryBoard instance. Unless you are infra-core or Zara or SotK, the best way to do this is to spin up your own test instance in a VM or somewhere.

    There are instructions on how to do that in /contribute/development. I won't go into detail here on the ins and outs of getting set up. When you have an up-to-date database you'll need to log in via the webclient. Upon successfully logging in, connect to your database with the mysql command line client, providing your password as prompted:

    mysql -u $YOUR_DB_USER -p

    Then run the following:

    connect $YOUR_DB_NAME;
    update users set is_superuser=1;

    This will make every user that has so far logged in to have superuser permissions.

    • (optional) Obtain a sanitised dump of the production database

      If you want to test migrating against production data, you'll need that data. The way to obtain this is to ask an infra core nicely.

      You can use the provided .sql file to recreate the production database in your local instance:

      mysql -u $YOUR_DB_USER -p < /path/to/db/dump.sql

    Warning

    This database will have the name storyboard, and will obliterate the contents of any database you already have with the same name.

  2. Create the StoryBoard project

    Log in to the webclient for your StoryBoard instance. When logged in, click the "Create New..." button, and pick "Project". Give the project a name (in storyboard.o.o this will match the git repository name, so you may as well use that) and a description.

    When you are happy with the name and description, and both are outlined in green, click "Create Project".

  3. Migrate!

    You can do this with the following command:

    tox -e venv -- storyboard-migrate
      --config-file etc/storyboard.conf
      --from-project $PROJECT_IN_LAUNCHPAD
      --to-project $PROJECT_IN_STORYBOARD

    Here, $PROJECT_IN_LAUNCHPAD should be replaced by the name of the project in Launchpad, for example monasca. Similarly, $PROJECT_IN_STORYBOARD should be replaced the name of the project you are importing into in StoryBoard, for example openstack/monasca.

    Two parameters of the storyboard-migrate command allows for filtering by the tags associated to the bug. Both parameters accept a comma-separated lists of tags and they are mutually exclusive.

    --only-tags=tags select only the bugs which have all

    the specified tag(s)

    --exclude-tags=tags exclude the bugs which have any

    of the specified tag(s)

    Then you must wait for some time to pass whilst the project is migrated. You can watch the output if you like. Sometimes it will crash with a traceback saying the database object already exists.

    If this happens, then your migration test has FAILED and you need to go shout at SotK to fix this bug (or fix it yourself if you have the spare time to help).

    Sometimes it might break in other ways for some reason. If this happens, then your migration test has FAILED and you have found a new and exciting bug. Report it in #storyboard and maybe on StoryBoard somewhere and try to fix it if you like.

  4. Check everything went smoothly

    At this point you have successfully run a migration. You now need to check that you haven't triggered any of the migration issues we know about currently.

    Check branches as described in 3.1, and also check that you can view the project page in the webclient. Page through the stories to make sure that none of them have content that breaks the webclient.

    Check that you can view the URL:

    http://localhost:9000/api/v1/stories?project_id=$YOUR_PROJECT_ID_HERE

    in a web browser. If there is trouble for your browser in rendering that then one of the stories has a non-unicode character in it which will ruin StoryBoard's day.

    If any of these checks don't succeed, then your migration test has FAILED.

    If they all succeed, then maybe so has your migration. Test everything you feel like testing, check some of the stories to make sure they look sane. Beware of things that look like a huge mess but are actually just our markdown parser mangling logs that weren't indented by the bug submitter. These aren't an issue but will probably make someone sad.

    Assuming you tested against production data and everything checked out, the project should be ready to migrate for real. If it wasn't tested against production data, now would be the time test against it as you may discover other bugs.

The Migration Process

  • One patch needs to be pushed to the project-config repo to modify projects.yaml to update 'use-storyboard' to True for each of your projects in that file
  • A representative from infra runs the migration scripts

Recently Migrated

  • Communicate to your project, your users and operators that bugs will now be filed in your storyboard project rather than launchpad project

  • Lock your launchpad project so that users and operators can't file bugs there. In the 'Change Details' section you should update information about where to file bugs now, then go to the 'Bugs' section and set the 'bugs are tracked' radio button to the 'somewhere else' option.

    Note

    Launchpad does not close open bugs or note the new location that people should make comments and updates at which is why it is important to communicate to users, operators, and contributors that you've migrated

Q & A

  • Is there integration with gerrit? Yes. Details here.
  • What happens to bug links? Bug numbers are the story numbers and are used in the url for the story
  • What happens to blueprints? They are not migrated because they are a construct tied to Launchpad. They can be optionally migrated, but it's not supported by default
  • How do I close a task? Change the status from 'Todo' to 'merged'. The state of the story overall is derived from each of the tasks. While tasks can be complete, the story may not be done until all tasks are marked as 'merged' or 'invalid'. See the gerrit integration link above for more details
  • Are there tags? Yes, anyone can add any tags to stories
  • Will I be able to write scripts for it? Yes, there is a REST API
  • Why are we using Storyboard? It was designed for the OpenStack use case and the ability to manage cross project efforts. It is managed by OpenStack and so it can be fixed and changed quickly.
