SDC amonredis core zone

SDC 7 has an amonredis zone. This repo builds it. The "amonredis" core zone runs redis for Amon's use only.

A redis instance can have a number of separate databases. By default this is 16, and the current redis config doesn't change that. A redis connection can select the DB it is using with the SELECT command.

Warning: Do NOT use the FLUSHALL! This will blow away data for other apps. Instead use FLUSHDB.

DB index

DB Index	Service
0	None. 0 is the default index. By design, no SDC service should use this index. This forces legal redis clients to explicitly choose an assigned DB index.
1	Amon (the 'amon-master' service in the 'amon' zone).

Operators Guide

This section is intended to give necessary information for diagnosing and dealing with issues with the "redis" zone in a SmartDataCenter installation.

To find the redis zone(s) use the following. Currently there is only one, though redis clustering might be possible at some point.

sdc-vmapi /vms?owner_uuid=$(bash /lib/sdc/config.sh -json | json ufds_admin_uuid) \
    | json -H -c "this.tags.smartdc_role=='amonredis'"

Look at the "redis" service.
