How to send a Portainer Webhook to recreate a container

I use Portainer v2.13.1. With a private secured Docker Registry. After activating the Container webhook in Portainer, I do a POST Request to generated URL.

enter image description here

But this fails with

{
    "message": "Error updating service",
    "details": "Error response from daemon: Head \"https://registry.mydomain/v2/my-gateway/manifests/1.0.3-RELEASE\": no basic auth credentials"
}

I added a Basic Auth in Postman to the request with my docker registry credentials. But this also not worked.

How I must build the request to make this work?

2.14 fixes it.

It's actually because of the way the header was being used in the docker proxy.

In 2.13 you're meant to pass a portainer registryId in the x-registry-auth, and not the docker credentials. I bet few have seen this little gem in the documentation.

It's because we were kind of overriding the standard header. But we've sorted that now so it'll take either option.
