This is more of a product issue because the debug image exposes Enterprise code.

Source code isn't obtainable from debug symbols, but a skilled programmer could rewrite an application's logic given the debug symbols and a lot of time. https://stackoverflow.com/questions/5532415/obtain-source-using-debugging-symbols#:~:text=The%20easy%20answer%20is%20No%2C%20you%20can't.

Oh. Got it. This should not be problem

We are currently running into issues trying to create and release the debug image in Cloudbuild due too the increased space requirements of the debug issue (~2.4GB vs ~200MB) Potential paths forward are:

• Attempt to modify the CI script to use fewer resources
• Allocate the required resources to the Cloudbuild

I'm not sure what the total requirements of the job are/will be, what the resource limit currently is, or how to modify it

solo-io/envoy-gloo-ee#405 is open under review It adds steps in CI to build and release debug images that can be profiled for tagged releases

[bewebi]

This has now been merged Debug images will be build and published for future tagged releases

[nfuden]

Reopening to also provide envoy-wrapper images by default.

[nfuden]

We will only be backporting to 1.11 and only publishing on new releases

[gunnar-solo]

debug images are now available in v1.12.18+

[nfuden]

This should be available 1.11.41
