Receive error code 502 when pushing images to container registry through a proxy

[mrsimonemms]

During the investigations of #10769, I made a simple version of #12829 by hardcoding all the envvars into an image. This gave a series of 502 errors when pushing images to my container registry.

Once the work for #12829 has been done, this will be the next thing to do.

NB this ticket is more an aide-mémoire that a problem potentially exists rather than an expectation of some work to be done

@mrsimonemms does this issue rename align with the problem you were experiencing?

[mrsimonemms]

Sure. It's perfectly plausible that this issue goes away when #12829 is done, so this issue shouldn't be worked on until that other issue is done
