Question

Is it possible to rebuild a droplet with new user data?

I’m poking around with RancherOS and I’m building a “provision script” that I pass into the Droplet creation user data. However, instead of destroying the Droplet every time I need to fix my script, I would like to know if there is a way to inject new user data in the rebuild process. This would prevent allowing a new IP address, and so on.

Thanks,

you could run your provision script on the host directly to test it out. For the most part it will ignore / pass over steps it has already completed. Keep in mind this is only best used for initial scripting and setup/debugging.

You may want to use something like Terraform to automate the creation/destruction of your droplet which can also load your user-data - https://www.terraform.io/docs/providers/do/index.html
