When doing any kind of attempts for aws:elasticbeanstalk:environment:proxy:staticfiles it just doesn't work. Every time I receive errors about invalid option specification. All the rest of ebextensions settings work like a charm.
Example snippet that I try:
option_settings:
aws:elasticbeanstalk:environment:proxy:staticfiles:
/stylesheets: public/stylesheets
/fonts: public/fonts
/html: public/html
Error on eb deploy:
2021-04-09 08:12:02 ERROR "option_settings" in one of the configuration files failed validation. More details to follow.
2021-04-09 08:12:02 ERROR Invalid option specification (Namespace: 'aws:elasticbeanstalk:environment:proxy:staticfiles', OptionName: '/stylesheets'): Unknown configuration setting.

Running EB platform with Docker on 64bit Amazon Linux 2, version 3.2.6. I start suspecting this staticfiles spec is unsupported on this platform for any reason but I crawled through AWS EB documentation seeking for any hints with no success. Interestingly, there is no static files section in the web console UI either.
I tried every configuration flavors - trailing slashes, quotation, different sets of those paths... Nothing worked.
staticfiles are not supported for Docker platforms. From docs:
Elastic Beanstalk supports configuring the proxy to serve static files on most platform branches based on Amazon Linux 2. The one exception is Docker.
