deploy.bash

#!/bin/bash
# This script is used to do rustup releases. It requires an AWS access token
# allowed to update our S3 buckets and to invalidate CloudFront distributions.
#
# Usage:
#
# 1. Deploy the release on the dev environment:
#    ./deploy.bash dev VERSION_NUMBER
#
# 2. Test everything works correctly:
#    RUSTUP_UPDATE_ROOT=https://dev-static.rust-lang.org/rustup rustup self update
#
# 3. Deploy the release to the prod environment:
#    ./deploy.bash prod VERSION_NUMBER
