Introduction

JS7 JOC should be able to connect to GIT repositories to store JS7 configuration objects. Configuration objects can be versionized (tagged) and rolled out to different JS7 instances via GIT.

The usage of GIT somewhat conrtradicts the usage of a database as the leading system to store configuration data.

JS7 is the leading system to store configuration data. A connection to a GIT repository can only be seen as an additional oportunity to versionize and to rollout JS7 configuration objects.

Configuration Objects

Configuration objects to be stored in a GIT repository:

  • Workflows
  • Locks
  • File Order Sources
  • Job Resources
  • Boards
  • Calendars
  • Schedules

GIT Repository Usage

The JOC web services execute a set of GIT commands with the implementation of JGit.

Storage

JS7 configuration objects are stored to a GIT repository via JOC web services.

Commands / Services

  • git-add
    • Adds (new) configuration object(s) from a working copy (currently the DB) to a local repository.
  • git-delete
    • Removes an already added configuration object from the local repository.
  • git-commit
    • Commits newly added, changed or removed configuration objects to a local repository.
  • git-push
    • Pushes the changes from the local repository to the connected remote repository.

Versioning

Versioning of JS7 configuration objects will be done with the tagging functionality of GIT. 

The JOC web services can manage the GIT tagging process.

Commands / Services

  • git-tag
    • tags the current commit with a version label
  • git-push
    • see above

Rollout

Rollout between different JS7 instances can be performed with the GIT functionality.

The JOC web services manage the checkout- and clone processes.

Commands / Services

  • git-checkout
    • checks out a specific branch or tag from the repository.
  • git-clone
    • clones a repository locally for the first time.
  • git-pull
    • pulls the recent changes from the remote repository into the local repository

Merge

TODO

Use Cases

Single User (Backup and Versioning Tool)

GIT repository usage:

  • storage
  • versioning
  • rollout

Requirements

TODO

dev, test, prod - single user

GIT repository usage:

  • storage
  • versioning
  • rollout
  • merge

Requirements

  • TODO
  • different versioning for different branches (dev, test, prod)
  • DB is the leading system (???) (single DB? for each branch?)
  • repository used for user versioning only
  • merges from branch to branch possible?
  • version can overwrite local (DB) versions as new configurations
  • new local configuration share latest version from DB (next version +1 or next version Snapshot)

dev, test, prod - multi user

GIT repository usage:

  • storage
  • versioning
  • rollout
  • merge

Requirements

  • TODO

  • different versioning for different branches (dev, test, prod)

  • different users each branch can commit (Merge needed! 3rd party Tool like KDiff?)

  • DB is the leading system (???) (Single DB (dev, test, prod) needed for each branch (Security/Network issues))

  • repository used for user versioning only

  • merges from branch to branch possible

  • version can overwrite local (DB) versions as new configurations

  • new local configurstion share latest version from DB (next version +1 or next version Snapshot)

  • No labels
