Looks good during my first checks.
looks good on OSX 10.4.6, will be testing this release on a 'serious'
build server farm over the weekend (rhe4).
how many servers constitutes serious?
the system consists of 6 servers, in pairs of 2 (dev/critical
towers)...allows client (and me) to deploy new build software (like ant)
easily without taking down critical build servers.
These server pairs each cater to different groups and roles in build
process which spans the globe;
Development build server pair: Is responsible for catering to a group of
40+ developers worldwide, e.g. builds the software and deploys to the
same box they determine via svn branch/tag
Test/Integration build server pair: Is where we have to test integration
with some other systems (mainframe db and some websphere specific stuff
that is too much of a burden on dev build server)..in addition run
functional and
Deployment build server: selects tagged versions for build, final
processing with respect to security thingies and handover to deployment
system...which then deploy to a test farm...which in turn is where the
app itself is hit at speed and scale.
I doubled up in kit, because we had the resources....and I like to keep
things simple when working at such scale...cfengine helps out with
keeping everything in sync.
That sounds like quite a rigorous process.
yes, cfengine and lcfg can keep your stuff in control. There's also
games you can play with vmware/xen hosted images, where the real CPUs
just host the virtual machines, and those you replicate off managed
"gold" images.
There is also
SmartFrog http://smartfrog.org/
Puppet http://reductivelabs.com/projects/puppet/index.html
both of these have a non-XML language to describe system configuration,
and runtimes to bring up distributed apps. I will cover smartfog in the
deployment chapter of Java-Dev-with-Ant (Jim, would you like to review
that chapter?), while puppet is something I know of but havent used
myself. It could be better at low-level linux config, because smartfrog,
being built on java and rmi, needs a lot more of the system working
before it can start configuring across systems.
