Subject: [PATCH] xslt-lab: chart 0.4.2 (backend resources) and a second
 backend replica
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The chart now declares resources for the backend container, which runs three
JVMs adding up to 512 MB of heap: it had been living on a manual kubectl patch
of 256Mi and was OOMKilled five times a day. minReplicas goes to 2 for the same
reason the frontend did — a restarting pod should not be the whole service.
