Why I got Unable to init from given url in laravel app under Docker?

I try to run laravel with media-library under docker(with PHP Version 8.1.4) and when I try to get properties of image with code :

if ( ! empty($CMSItemMedia) and File::exists($CMSItemMedia->getPath())) {
    $CMSItemImage['url']        = $CMSItemMedia->getUrl();
    \Log::info(  varDump($CMSItemMedia->getUrl(), ' -1 $CMSItemMedia->getUrl()::') );
    $imageInstance              = Image::load($CMSItemMedia->getUrl());
    \Log::info(  varDump($imageInstance, ' -1 $imageInstance::') );
    $CMSItemImage['width']      = $imageInstance->getWidth();

I got next logging lines and error :

[stacktrace]

If to open file in browser url

http://127.0.0.1:8088/storage/currency_app/21/our_rules.png 

file is opened ok.

In phpinfo output I see that gd is intalled in my docker OS :

GD Support  enabled
GD Version  bundled (2.1.0 compatible)
FreeType Support    enabled
FreeType Linkage    with freetype
FreeType Version    2.10.4

I have in my app :

"spatie/laravel-medialibrary": "^10.0.0",
"intervention/image": "^2.7",

    

and in .env :

APP_URL=http://127.0.0.1:8088

so my app runs by http://127.0.0.1:8088 url.

In Dockerfile.yml file I have gd installed :

    apt-get install --assume-yes --no-install-recommends --quiet \

    && a2enmod rewrite

    RUN apt-get install -y grep mlocate

    COPY virtualhost.conf /etc/apache2/sites-enabled/000-default.conf

I do not have such problems under hosting Kubuntu 20.
What is wrong ? Did I miss some docker options ?

Thanks!
