Advice on building `control-tower` locally

[corinja]

Hi. Not sure this will get read but trying anyhow ...

I'm trying to build a fork of control-tower to see if we can keep on using this as a way to deploy & maintain our Concourse.

Although I have run the local tests and built a control-tower executable, when I try to do a deploy to AWS it runs fine, creating all the various AWS services nicely, until it encounters:

Error loading state file after create-env: [open /var/folders/36/jxbwdvbn56327wjxz2q2bzc40000gn/T/control-tower1865910723/state.json: no such file or directory]

This is during the GENERATING BOSH DIRECTOR CERTIFICATE (xx.xxx.xx.xxx, xx.x.x.x) step.

I can see this error is in the bosh/internal/boshcli/boshcli.go file, but I don't understand it.

Can anyone help?
