Mesos Configuration

The Mesos master and slave can take a variety of configuration options through command-line arguments, or environment variables. A list of the available options can be seen by running mesos-master --help or mesos-slave --help. Each option can be set in two ways:

• By passing it to the binary using --option_name=value, either specifying the value directly, or specifying a file in which the value resides (--option_name=file://path/to/file). The path can be absolute or relative to the current working directory.
• By setting the environment variable MESOS_OPTION_NAME (the option name with a MESOS_ prefix added to it).

Configuration values are searched for first in the environment, then on the command-line.

Important Options

If you have special compilation requirements, please refer to ./configure --help when configuring Mesos. Additionally, this documentation lists only a recent snapshot of the options in Mesos. A definitive source for which flags your version of Mesos supports can be found by running the binary with the flag --help, for example mesos-master --help.
