DC/OS uses Marathon to manage your processes and services.
Marathon is the “init system” for DC/OS. Marathon starts and monitors your applications and services, automatically healing failures.
A native Marathon instance is installed as a part of DC/OS installation. After DC/OS has started, you can manage the native Marathon instance through the DC/OS CLI with the
dcos marathon command.
DC/OS services are Marathon applications that are deployed on DC/OS. DC/OS services are available from a package repository, such as the Mesosphere Universe, or you can create your own.
You can run DC/OS services you create or install a package from the Catalog. Both the services you create and those you install from Universe appear on the Services tab of the DC/OS web interface when they are running.
Services you create yourself are administered by Marathon and can be configured and run from the DC/OS CLI with
dcos marathon subcommands (e.g.
dcos marathon app add <myapp>.json) or via the DC/OS web interface.
Universe Package Repository
Packaged DC/OS services created by Mesosphere or the community, like Spark or Kafka, appear on the Catalog tab of the DC/OS web interface, or you can search for a package from the DC/OS CLI. You can configure and run Universe services from the DC/OS web interface or via the DC/OS CLI with the
dcos package install <package-name> command.
