bc-agentservice Mesos

This is a scheduler service which executes jobs within an Apache Mesos compute cluster.

Environment variables

BEYONDCRON_DIR_CONFIG location of configuration directory.
MESOS_CONFIG Name of a configuration file containing Mesos service configuration variables. If not an absolute file name, BeyondCron will search BEYONDCRON_DIR_CONFIG, the directory in which bc-agent was started, and ~/.MESOS_CONFIG for this file. Default = mesos.dat
If the value of MESOS_CONFIG, contains one or more newline “\n” characters, then BeyondCron will attempt to parse it directly.
