# Add ""--exclude 'img' --exclude 'js' --exclude 'downloads' --exclude 'css'"", to the command to control cache behaivor.
aws s3 sync --profile ${PROFILE} --acl "public-read" --sse "AES256" public/ s3://${BUCKET_NAME}/

### (OPTIONAL) Ensure static files are set to cache forever - cache for a month --cache-control "max-age=2592000"
# aws s3 sync --profile ${PROFILE} --cache-control "max-age=2592000" --acl "public-read" --sse "AES256" public/img/ s3://${BUCKET_NAME}/img/
# aws s3 sync --profile ${PROFILE} --cache-control "max-age=2592000" --acl "public-read" --sse "AES256" public/css/ s3://${BUCKET_NAME}/css/
# aws s3 sync --profile ${PROFILE} --cache-control "max-age=2592000" --acl "public-read" --sse "AES256" public/js/ s3://${BUCKET_NAME}/js/
# aws s3 sync --profile ${PROFILE} --cache-control "max-age=31536000" --acl "public-read" --sse "AES256"  static/downloads/ s3://${BUCKET_NAME}/downloads/

### Invalidate cache so that everything is up-to-date (Warning, first 1K/mo free, then 1/2 cent each)
aws cloudfront create-invalidation --profile ${PROFILE} --distribution-id ${DISTRIBUTION_ID} --paths "/*"
