Self-hosted imgProxy and Shopware plugin

[csaeum]

I have a question about using imgproxy as self-hosted with Docker:

In the plugin I can only specify the following:
available variables:
{mediaUrl}: https://cdn.test.de/
{mediaPath}: media/image/5b/6d/16/tea.png
{width}: 800
{mediaUpdatedAt}: 1716882050 (unix timestamp) or 0

Hence my question:
mediaUrl: isn't that from the imgProxy server?
mediaPath: is the path to the image on the Shopware server and the data comes from the plugin?
width: is the width, which then comes from the plugin?
mediaUpdatedAt: is the last date the image was uploaded to the server?

I know from an earlier version that you had to enter a key to authenticate yourself, but apparently you don't have to do that anymore.

This is specified in the standard:

{mediaUrl}/{mediaPath}?width={width}

Do I then just have to add my URL in front of it? Example: https://imgproxy.domain.de/{mediaUrl}/{mediaPath}?width={width}

or should you use the patterns from the documentation:
https://imgproxy.domain.de/_/rt:fit/w:{width}/h:0/g:sm/plain/{mediaUrl}/{mediaPath}

if I currently send something to the server I get this:
WARNING [2025-02-21T11:40:21Z] Completed in 290.009µs /https://shopdomain/media/86/ae/cd/1740135217/froshthumbnailprocessortestimage.jpg?width=200 request_id=g0KGc313SRa4F_qKGJ-QR method=GET status=403 client_ip=31.18.23.211 error="Invalid signature encoding"

You might want to check the dedicated pattern discussion here: #36

Regarding Signature: this is not supported by this plugin. There was a dedicated addon which has been archived while there was no usage: https://github.com/FriendsOfShopware/FroshPlatformThumbnailProcessorImgProxy

OK, then I just need to get imgproxy to accept the URL even if there is no signature.

So whitelist the shop(s) to still generate the images.
