Happy Week 39 Everyone,

This week I mostly worked on the next part of the Juju AWS instance profile work. Specifically around providing a new bootstrap credential type and re configuring of state initialisation for a new Juju controller.

Worked on pylibjuju integration tests:

Tox version issues is solved – [PR]
Collection already exists problem is solved (thanks @simonrichardson) – [PR]
LXD network query problem is solved – [PR]
A long time failing ssh on manually provisioned machines issue is solved [PR]

I got more comfortable playing with lxd containers, and working on juju's own codebase.

My plan for next week (#40) looks like some debugging and working on some feature requests on pylibjuju.

p.s. Also considering different strategies to remember writing in the weekly team updates on time.
