Add ability to set default region

[petems]

Add a field into .tugboat that gives a default region when doing a droplet creation, so when you create a droplet it will use that value by default.

Agreed!

I also think it'd be worth adding size_id, image_id, etc. all at once. Basically all the defaults we have on create

[petems]

Good idea 👍

Hows this is one going? DigitalOcean wants to write an article about Tugboat and I suggested they hold off for this feature, as they were going to suggest doing environment variables / aliases for defaults.

Can I help at all? 😄

I did an initial spike here: https://github.com/pearkes/tugboat/tree/pm_default_region_option

Feel free to fix it up, I just added in a question to ask default region, so if you just add in the rest of the default options (size, image etc.) then it's pretty much good to go? 👍
