Re: Update Parallelization in Cloud Foundry

You can set the "serial" property at the global level of a deployment (you
can think of it as setting a default for all jobs), and then override it at
the individual job levels. You will want the consul server jobs to be
deployed first, with serial: true, and max_in_flight: 1. The important
thing here is, if you have more than one server in your consul cluster,
they need to come up one at a time to ensure the cluster orchestration goes
smoothly. The same is true if your etcd cluster has more than one server
in it. If you're using the postgres job for CCDB and/or UAADB (instead of
some external database), then you will want the postgres job to come up
before CC and/or UAA. Similarly, if you're using the provided blobstore
job instead of an external blobstore, you'll want it up before CC comes up.
You might be able to get away with parallelizing some of the things above.
E.g. if you bring the CC and blobstore up at the same time, CC might fail
to start for a while until Blobstore comes up, and then CC might
successfully start up. Monit also generally keeps retrying even after BOSH
gives up. So your deploy might fail but later on, you might see everything
up and running.
