marathon 1.6.322
官方：https://mesosphere.github.io/marathon/
一 简介
Marathon is a production-grade container orchestration platform for Mesosphere’s Datacenter Operating System (DC/OS) and Apache Mesos.\
marathon是一个DC/OS和mesos上的容器编排平台；
Features
- High Availability. Marathon runs as an active/passive cluster with leader election for 100% uptime.
- Multiple container runtimes. Marathon has first-class support for both Mesos containers (using cgroups) and Docker.
- Stateful apps. Marathon can bind persistent storage volumes to your application. You can run databases like MySQL and Postgres, and have storage accounted for by Mesos.
- Beautiful and powerful UI.
- Constraints. These allow to e.g. place only one instance of an application per rack, node, etc.
- Service Discovery & Load Balancing. Several methods available.
- Health Checks. Evaluate your application’s health using HTTP or TCP checks.
- Event Subscription. Supply an HTTP endpoint to receive notifications - for example to integrate with an external load balancer.
- Metrics. Query them at /metrics in JSON format or push them to systems like graphite, statsd and Datadog.
- Complete REST API for easy integration and scriptability.
特点：高可用、支持多种容器运行时环境、支持状态应用、UI、支持部署限制、服务发现&负载均衡、健康检查、事件订阅、日志收集、REST API；
DC/OS features
Running on DC/OS, Marathon gains the following additional features:
- Virtual IP routing. Allocate a dedicated, virtual address to your app. Your app is now reachable anywhere in the cluster, wherever it might be scheduled. Load balancing and rerouting around failures are done automatically.
- Authorization (DC/OS Enterprise Edition only). True multitenancy with each user or group having access to their own applications and groups.
在DC/OS上还提供虚ip和认证；
