Google Cloud SDK

There are two alternatives to start with the SDK:

1. install SDK locally;
2. use provided Linux VM in the cloud via ssh.

Note: everyone will get a separate index, ie. hacker02, hacker03, etc.

$ ssh hacker01@wp-workshop.hosting.lv

Registrator and SkyDNS

We use progrium/registrator and yaronr/skydns (SkyDNS2) to publish information about Docker containers to DNS via A and SRV records. All nodes runs skydns and registrator, and first three nodes are inserted as NS-s into Route53 DNS for services.cluster-name.domain.io. Note, v4 registrator must be used until registrator/124 is resolved.

$ host -t srv mysql-1.services.deis.r53.acp.io deis-6-1.eu.r53.acp.io
Using domain server:
Name: deis-6-1.eu.r53.acp.io

1. Koding - Attach your own VM. Nice UI. Has Chrome app.
2. Cloud9 - 512MB free tier memory limit. Scala and Groovy processes will be killed pretty soon due to OOM.
3. Codenvy - Docker runners automagic fail (cannot run arbitrary startup command). Can show Javadoc.
4. Nitrous - defunct.
5. Codebox - defunct.
