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

Integrated with diskimage-builder

You know what has less depends than minimal python?

+
+ +
+

Rust
