You need to use https://github.com/bytedance/g3/blob/master/g3proxy/examples/simple_http_gateway/g3proxy.yaml this as an example HTTP reverse proxy config. The You need to mount your g3proxy.yaml config file or config dir when start the docker container, and change the entry command to |

The g3proxy container has a http_proxy server, which is a forward proxy mode server, you can test it with I think you need to expose the ports in g3proxy container to the host, so you can run it from the host. I will try this when I have some free time. |

I did try your example. And as you pointed out in the link, DNS services it is an issue with the my the docker DNS "resolver.conf" not correctly pointing to my Docker service. Which I'm working out next after several attempts below trying to avoid looking at this. *edit: |

Thank you, you solved my problem. I was on a tangent with assigning IPs, I haven't tested your better solution yet, it appears cleaner than what I used below. I will keep experimenting and learning more about G3Proxy and integrating it with Docker. I have a lot of use cases I want to test out. I consider this solved. |

Ok, this I think the whole time I only needed to include whatever was my docker named network compose.ymlnetworks:

can you try: resolver:
- name: default
type: c-ares
#server: --> delete this and use default address in /etc/resolv.conf
# - 127.0.0.11I think that the containers are in a connected network by default, so you can also try to delete that g3w-net definition. |

It seems that the /etc/resolv.conf file in the container is mounted at start and it's correct. What I means is that you can just use resolver:
- name: default
type: c-areswithout set the DNS server address manually, and then g3proxy will read the /etc/resolv.conf file in the container and get the correct DNS server address from there, which will make the config file more portable. |

this is a new feature I added recently, so you need to rebuid the docker image to the latest commit |

Works! and is I did a complete prune of docker, including the buildx cache. And I restarted twice to confirm Everything still works, just an anomalous entry in the log file type I get this in my Filescompose.ymlservices:

How do I make a reverse proxy with g3?
Your documentation is very good but my cave man literacy level is lower than any other recorded caveman.
I understand some caveman technology and I can often make other rocks that cavemen use work. I usually see how the other cavemen smash rocks and then repeat their rock smashing actions with my own rocks.
But these rocks look a little different than what this caveman encountered seeing other caveman use and is not getting an immediate fire in his cave.
How do I smash these rocks together to make a reverse proxy?
Caveman first procured the rocks like so.
And this Caveman then sees that his rocks are indeed in his cave now.
Caveman then poked the rock and not smash the rock yet to verify it is a working rock.
Caveman now wants to use his rock on his VPS I mean Cave to point from the entrance of his cave to another
special rock in his cave whenever someone enters his Cave.
Caveman is not good with "words" and wants to see rocks!
I think this is the cave pit that I need to use for the "whoami" reverse-proxy
