Buildpacks can use proxies via the
https_proxy environment variables. These should be set to the proxy hostname and/or port.
These can be set via the manifest.yml file or
All of the buildpacks will automatically utilize these proxy environment variables correctly. If any of them contact the internet during staging, it will be through the proxy host. The binary buildpack will not use a proxy because it does not use the internet at all during staging.
--- env: http_proxy: http://proxy-site.com:3000 https_proxy: https://proxy-site.com:3003
Note: Whilst many applications will use the
environment variables at runtime, this is entirely dependent on your
application, the buildpack does not add any extra functionality to make proxies
work at runtime.
