Dockerfile Assets
For Rails, Within the docker build command assets precompiled. Assets are copied out of the docker build image and uploaded to s3 for asset serving.
config asset_host
To configure the Rails app to serve the assets from the Jets managed s3 bucket.
config/environments/production.rb
Rails.application.configure do
config.asset_host = ENV['JETS_ASSET_HOST'] if ENV['JETS_ASSET_HOST']
end
The JETS_ASSET_HOST is automatically set as part of the jets deploy process. It points to either:
- The Jets s3 Bucket with under the
jets/publicpath where the assets are uploaded to, IE: https://demo-dev-s3bucket-5lfgasr90ldd.s3.us-west-2.amazonaws.com/jets/public - The Uploads CloudFront CDN which is configured with the Jets S3 Bucket as the Origin. Using CloudFront is recommended. IE: https://assets0.example.com
Disabling Assets Uploading
If for some reason, you want to disable asset serving from S3.
config/jets/deploy.rb
Jets.deploy.configure do
config.assets.enable = false
end
