Open Infrastructure

In theory it should "just" work, let's see what is necessary.

We need:

• ungleich-otp for authentication
• etcd for storing configurations and run time data

The story / handbook¶

• My objective is to use ucloud for scheduling VMs
• I do need some kind of authentication system, ucloud uses one time passwords based on RFCXXXX
  • One reference implementation for that is uotp, so we install uotp first
• I need some kind of database for storing information in
  • ucloud chose etcd
  • So I need to install etcd first

Arch Linux specific¶

• Installing etcd via AUR
  • yaourt -S etcd

ucloud-setup¶

• If I don't trust shell scripts, ucloud-setup is a bit tricky
• Maybe we need to describe the shell script more in detail / on the website2

Required follow ups¶

• It's nice that all components are depending on etcd only, however ungleich-otp also depends on postgresql
  • We should shortly rewrite the backend of ungleich-otp to be etcd, too
• We should probably have some kind of check for each step, f.i. etcd running is missing
