Concurrency: Global Pools of Credentials

[Ryan Cocks]

I'm reaching out for solutions to the following problem:

We are using Jenkins to run some watchdog tests against a cloud cluster. Our tests use accounts that can't be shared between concurrent runs of the tests. To allow our tests to run in parallel we created multiple sets of accounts.

I want to put these sets of accounts we created into a shared pool. When a test that needs these credentials runs it should take a set of credentials out of the pool while it runs and then return them afterwards.

As these are cloud accounts the pool needs to be global to Jenkins - i.e. it's not a per node shared pool, it's a global one.

I spent some time looking at this a while ago and we have a solution in place, but it uses a modified version of the port allocator plugin and is something of a hack. We've used convention around how accounts are named so I can map a simple integer into a set of accounts.

Any solutions?

Thanks in advance for any input!
