[ibreakthecloud]

Describe the bug
I have created a docker extension, currently the code is private. when I do
docker build -t secretscanner-docker-extension:latest .
and then
docker extension install secretscanner-docker-extension:latest

I am able to use the extension properly, ui is able to do
ddClient.extension.vm?.service?.get('/ping')

But, when I do
docker build -t deepfenceio/secretscanner-docker-extension:latest .
and then
docker extension install deepfence/secretscanner-docker-extension:latest
ddClient.extension.vm?.service?.get('/ping') throws below error in console log

{name: 'Error', message: 'socket hang up', statusCode: undefined}

my docker compose yaml

version: '3'
services:
  app:
    image: ${DESKTOP_PLUGIN_IMAGE}

  deepfence-secret-scanner:
    container_name: deepfence-secret-scanner
    image: deepfenceio/deepfence_secret_scanner_ce:latest

Also, If I exec inside service container do curl to /ping it works for both the cases

I Hi @ibreakthecloud thank you for reporting this!

I can reproduce this as well. This could be related to the length of the socket path. If I change the image tag to a/b:latest it works.
This is something we know, we must find a way to shorten the socket path.

Thanks for the quick reply @benja-M-1 .
Is there a way to manually put the socket path, instead of letting it generate?

[benja-M-1]

Unfortunately, no, there is not. In metadata.json you can shorten the name of the generated socker but it may not be enough. The name of the extension also counts in the length.

In Docker Desktop 4.15 we've improved the docker extension init command to generate a shorter socket name in the metadata.json that does not depend on the extension name. No matter the name of your extension, the socket name will be backend.sock.

@ibreakthecloud In your existing metadata.json file, could you replace the socket name with a shorter one such as backend.sock?

While this is not a definitive solution, it will reduce the likelihood of hitting this issue.
