Launching apps via the UI

Go to DC/OS dashboard and click on the Marathon service

In the Marathon UI:

• Create an app with ID hw such as while [ true ] ; do echo "Hello world!" ; sleep 10 ; done
• Scale it up and down
• Kill tasks
• Explore logs
• Update the app spec to while [ true ] ; do echo "Hello DC/OS!" ; sleep 5 ; done and discuss what happens

Launching apps via the CLI

Simple app server:

$ dcos marathon app add peek.json
$ dcos marathon app list
$ dcos task

Try the other ones:

• A web server: nginx.json
• A simple blog: jekyll.json
• A Slack-like chat app: mattermost.json

For the following you'll need to have Marathon-lb installed:

• A Wordpress blog wordpress.json

This one uses VIPs for service discovery:

• An app server vipwebserver.json
