How to force docker-compose to go through a proxy?
Registered in /etc/systemd/system/docker.service.d/http-proxy.conf
and even tried in /etc/systemd/system/docker.service.d/proxy.conf

[Service]
Environment="HTTP_PROXY=http://127.0.0.1:8888"
Environment="HTTPS_PROXY=http://127.0.0.1:8888"

After of course I restart the daemon and the service
But to no avail ... I go into the container and try $wget -qO- eth0.me and it shows me my ip, not the proxy.
On off-dock, I also tried to create a .docker folder in the root profile and there the config file.

Well, for starters, the variable for wget should be called http_proxy, not HTTP_PROXY...
Then, it's better to set it for a specific container, and not for the whole docker. If this is needed during the container build process, specify it in the Dockerfile via ARG (not via ENV).
