Chromebook/Droplet Dev Env Best Practices?

Looking for best practices/lessons learned around using a droplet to host all dev work. I’ve googled, but nothing is quite what I am looking for…

I’m using a chromebook and want to combine it with a docker droplet to provide a full dev environment. I want a setup script that will startup a droplet, configure the tools, clone the repo, and provide the engineer with a fully configured environment.

Chromebook Config termux “secure shell” small subset of dev tools (zsh, git, vim, golang, openssh) doctl (for droplet mgmt actions)

Ideas

1. clone repo onto docker-droplet, access repo from docker images (i.e. golang:latest or similar)
2. mount a remote dir (on chromebook?) that contains git repo, work on droplet
3. create a docker data volume that contains the repo, use with tools docker image

My preferred approach is option 1, but I can’t figure out how to clone without private ssh key access in the droplet.

Any thoughts, pointers, or experiences are appreciated.
