pack/paketo behide a proxy

Question

I'm using buildpacks and paketo to build my images from a spring-boot gradle project.

I'm behind a corporate proxy (using cntlm and already exported: http_proxy=http://localhost:3128 and https_proxy=http://localhost:3128)

I've also added a configuration file for docker ~/.docker/config.json:

{
  "proxies": {
    "default": {
      "httpProxy":  "http://localhost:3128",
      "httpsProxy": "http://localhost:3128"
    }
  }
}

But I'm stuck with this error :

Any idea to fix this ?

You need to configure this in your build.gradle file.

tasks.named("bootBuildImage") {
    environment["HTTP_PROXY"] = "http://proxy.example.com"
    environment["HTTPS_PROXY"] = "https://proxy.example.com"
}

https://docs.spring.io/spring-boot/docs/3.0.5/gradle-plugin/reference/htmlsingle/#build-image.examples.builder-configuration

This will allow the buildpack that runs inside of the container, created from the builder image, to access the internet through the defined proxies.

As you can see I'm not using `bootBuildImage` – flywell Mar 24 '23 at 07:56
It's actually not clear, you mentioned "spring-boot gradle project", so that's the direction I went. – Daniel Mikusa Mar 24 '23 at 16:44
Pack has this documented here -> https://buildpacks.io/docs/app-developer-guide/using-http-proxy/. It will pick up and pass through http_proxy and https_proxy from your local env to the buildpacks, so if that's not working double check how you're exporting those variables. – Daniel Mikusa Mar 24 '23 at 16:46
