When you boot a VM, it needs boot time data or bootstrapping

-
- -
-

I use ansible for orchestration

-
- -
-

I don't need boot time fancy, - I JUST need ssh bootstrap

-

Ok. And maybe network

-
- -
-

Things I must consume at boot

-
    -
  • - Network Configuration -
  • -
  • - maybe SSH Keys -
  • -
-
- -
-

Network information should be easy

-

There is this thing called DHCP

-

Dynamic Host Configuration Protocol

-
- -
- -
- -
-

Some providers don't support DHCP - because bong

-
- -
-

cloud-init

-

Handles many cases, but not all

-

Has lots of dependencies that conflict with gate depends

-

'frozen' pending 2.0 rewrite

-
- -
-

glean

http://git.openstack.org/cgit/openstack-infra/glean

-
    -

    No dependencies

    -

    Handles future static network config in config drive

    -

    Optionally also reads ssh keys from config drive

    -

    Nothing else

    -
-
- -
-

network_info.json

-

Hopefully added in liberty

You know what has less depends than minimal python?
