Docker ip forwarding inside container install#
On the docker-host, install a real REVERSE-PROXY (like NGINX) and configure it accordingly to matomo documentation mentioned above. Afterwards, you only need to setup your external networking, sending the HTTP traffic to the container IP, and no more the docker-host IP. So, in the end, you have only two options:Ĭhange the docker configuration, asking the docker-host to logically connect your matomo container to the EXTERNAL network, exposing it exactly like any other host on your LAN. Run a container in background, using the same IP as in the db. file. Without entering into details (out of scope of this answer), the problem is that you DON'T have the place to properly configure the reverse-proxy actions you need. In this example the name is bind9: sudo docker build -t bind9. unfortunately the above is not strightly suited to your case as the docker-host is not strictly running a REVERSE-PROXY "server", but, instead, is acting as a PORT-FORWARDER router. In your case, I'd suggest going through the official document to get un understanding about the whole concept and related countermeasures. The above is really common within so-called "cloud environment" and, as such, there are several ways to solve the visibility problem you're facing (knowing the real source IP of the HTTP request you're serving). it "proxy" (actually: "forward") the request to your container. the real source host send the request to your docker-host (to the public IP address associated to the external interface of your docker host).In technical terms, the docker-host is acting -with respect to your container- as a (sort-of) REVERSE PROXY. So, back to your case, as your container is receiving the HTTP request from the docker-host, this is exactly the reason why you see what you see (the HTTP request coming from the IP of your HOST, and not the one of the real source, on the Internet). But in general, you can assume the above. Lots of edges can be tuned by properly configuring Docker networking parameters to adapt them to your needs. So if you want to add rules to the FORWARD chain you have to add the rules to DOCKER-USER instead such that they are not overwritten.

Running curl -4 inside the container should now show the IP you have when tunneling your traffic through the VPN.

When you deploy something via a Docker-container, you have to keep in mind that it's (normally) not-directly-connected to the rest of the world (the Internet, in your case) and that such a connection (container Internet) is mediated by the Docker-host (the PC hosting the docker environment and properly running your container) resulting in a chain that looks like:Īctually, even if you haven't provided the details, I expect a real scenario like this: Routing a Docker Container through an OpenVPN Interface.
