Barak Korren updated OVIRT-2254:
--------------------------------
Assignee: Barak Korren (was: infra)
Status: In Progress (was: To Do)
> Create slave borrowing flow
> ---------------------------
>
> Key: OVIRT-2254
> URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2254
> Project: oVirt - virtualization made easy
> Issue Type: New Feature
> Components: Jenkins Master, Jenkins Slaves
> Reporter: Barak Korren
> Assignee: Barak Korren
>
> Create a set of jobs and groovy functions that will enable one Jenkins master
> to borrow slaves from another Jenkins master.
> h3. Acceptance criteria
> # We define a borrower and a borrowing Jenkins instances. Ans support the use
> case where both are the same instance
> # Borrowing is done by setting up a JNLP connection from the slave of the
> borrower instance to to borrowing instance.
> # On the borrower instance:
> ## We have a "borrow" job that:
> ##* Takes slave requirement details, allocates a matching slaves and make it
> connect via JNLP to the borrowing instance
> ##* If all matching slaves are already borrowed by other instances, try to
> call the garbage collector jobs (see below) on borrowing instances to free
> the slaves.
> ## We have a "return" job that is called by a borrowing instance to return a
> slave
> # On the borrowing instance
> ## STDCI tries to borrow slaves from a predefined instance if not matching
> slaves are available locally
> ## Once borrowed - slaves stay attached to the borrowing instance so they can
> be reused by other STDCI jobs.
> ## We have a "garbage collector" job that is triggered periodically or by the
> borrower instance. It looks at borrowed slaves, and frees ones that were not
> used recently.
