Overview
DC/OS is the Data Center Operating System from Mesosphere. It is built upon Apache MESOS and is designed to turn your data center into a single pool of resources that applications can utilise.
Mesosphere released DC/OS open source edition to run on a number of cloud computing services and also support for Centos, this charm leverages that capability to install DC/OS inside Ubuntu using the Juju modelling framework.
Juju and DC/OS make an excellent fit because it allows administrators to add new resource as simply as adding more DC/OS Agent units and deploying more applications.
Usage
Warning
This charm is currently under heavy development and has limited testing outside of EC2
Deploying this charm:
juju deploy dcos-master
To view the dashboard:
juju expose dcos-master
and visit http:/// to view the landing page. To view the Zookeeper info you can also visit http://:8181.
Scale out Usage
DC/OS provides a master and agent setup. For fault tolerance it is recommended to run more than 1 master node, these are self configuring and distributing.
This DC/OS charm will accept 1,3 or 5 masters. DC/OS performance actually degrades with more and 3 or 5 will provide HA capabaility.
Unlike the DC/OS official installations, this will allow for scalaing using juju add-unit to add new master nodes.
Known Limitations and Issues
This charm is an initial prototype to ensure that the main services bootstrap and applications can be deployed, there will be a number of missing features and usability issues. To help get in touch! (info@spicule.co.uk)
