How can I make docker-compose pull images using a socks5 proxy?

Method 1

Error:

docker-compose up 
Pulling web (jitsi/web:stable-6433)...
ERROR: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

then setting HTTP_PROXY and HTTPS_PROXY this way:

export HTTP_PROXY=socks5://localhost:9040/
export HTTPS_PROXY=socks5://localhost:9040/

result:

docker-compose up 
Pulling web (jitsi/web:stable-6433)...
stable-6433: Pulling from jitsi/web

A shot of before HTTP_PROXY and after setting them up:

Method 2

If method 1 did not work (simple one) you can go with this one:

first

Find systemd location for configuration:

systemctl status docker | grep docker.service\;
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

which here for my on Debian 9 is /lib/systemd/system/docker.service and its directory is /lib/systemd/system/ So cd into /lib/systemd/system/.

second

mkdir for docker.service.d or:

mkdir docker.service.d && cd !$

third

In docker.service.d directory create a .conf file like: http-proxy.conf

forth

Add these in http-proxy.conf file:

[Service]
Environment="HTTP_PROXY=socks5://localhost:9040"
Environment="HTTPS_PROXY=socks5://localhost:9040"

NOTE that localhost:9040 is mine, update it if you have a different IP or PORT

sixth

Because we update the configuration run:

systemctl daemon-reload

and then restart docker service

systemctl restart docker

Now it is up and running:
