Shifter starts to support sub directory publish, but you still need to do some works with it if you're publishing artifacts into the external server like AWS S3 or Netlify. In this document, we want to introduce and describe our script and how to do it. The webhook for sub directory publishing to the Netlify is available now.

Steps

Step 1. Download an artifact from Shifter dashboard

See: How to download an artifact

Step 2. Get the converting script

Copy, paste the script in the script section to your notepad and save it.

Step 3. Run the script for downloaded aritfact

Step 4. Publish converted artifact to external server like AWS S3 or Netlify.

Script

Copy and save as you like.
