juguerre/alpine-proxy repository overview

⁠Get started

This image is expected to be run this way on an Ubuntu server:

docker run  --rm --name proxy --cap-add NET_ADMIN --network host juguerre/alpine-proxy 

⁠Services

The container will have access to host networking and will run 2 services:

• Squid proxy server on port [3128]
• dnsmasq server on port [53]

Note: These ports must not be in use on the host.

⁠Ubuntu systemd-resolved.service on port 53

You can stop local DNS service in ubuntu with:

sudo systemctl start systemd-resolved.service

Now you can run this image that will run dnsmasq on port 53.

Note: you probably won't have internet conection if you stop systemd-resolved.service and do not run this image in its place.

⁠Networking

During container initialization iptables will be edited. Once the container is running iptables should look like:

route -n
