docker-zabbix-agentd

A Debian latest based Docker container running zabbix_agentd in a CoreOS instance.

Environment variables prefixed with "ZBX_CONF_" will be written to /etc/zabbix/zabbix_agentd.d/80-env-generated.conf (override by setting ZBX_CONFIGFILE).
ZBX_CONF_ServerActive=proxy02,server01 => ServerActive=proxy02,server01
To support multiple UserParameter settings "_[0-9]*" will be cut from the end.
