DNS-Onward
A CoreDNS based service that forwards traditional DNS requests to a DNS-over-TLS upstream server
Quickstart
Run docker run -e SERVICE="cloudflare" -p 53:53 -p 53:53/udp eldridgea/dnsonward
This will start the service using Cloudflare as its upstream DNS server. You can replace "cloudflare" in the line above with either "google" or "quad9" to use their servers instead. This will open up port 53 on your machine and allow it to accept incoming DNS requests. environments WARNING: It is NOT recommended to expose this service to the entire Internet, just in private network environments.
Supported Devices and Architectures
This supports ARMv7 and amd64 architectures so this should work on on most servers as well as Raspberry Pis. I have tested it successfully on my Pi 4 running Raspbian 10. If you're having an issue on other Pi hardware/OS versions please open an issue.
Variables
This is CoreDNS-based service intended to be run in environments where traditional DNS requests need to be encrypted before querying an upstream server.
This is intended to be run as a docker container and configured with environment variables.
Onward DNS supports Cloudflare, Google, and Quad9 out of the box with the SERVICE
variable, but can also be configured for any DnS-over-TLS (DoT) server.
If you are starting this container you should either supply it with the SERVICE
environment variable OR supply it with at least the IP1
and SERVERNAME
variables.
| Env Variable | Function | Values |
|---|---|---|
| SERVICE | Auto configures Onward DNS based on supported services |
google
, cloudflare
, and quad9
|
| IP1 | A primary upstream DNS IP Address | Any IPv4 Address |
| IP2 | A secondary upstream DNS IP Address | Any IPv4 Address |
| SERVERNAME | The TLS servername | The domain name of the DoT server |
| CACHE | The amount of time DNS responses are cached locally |
Time in seconds e.g. 100s
. Default is 30s
|
Multi-Arch Builds in Docker
This is pushed to the eldridgea/dnsonward
Dockerhub repository using Docker's experimental multi-arch build tool buildx
. Building this repo using the standard docker build
process should continue to work fine, but to build a multi-arch image yourself in this repo use, make sure you have buildx
enabled and run:
docker buildx build --platform linux/amd64,linux/arm/v7 -t eldridgea/dnsonward --push .
and replace eldridgea/dnsonward
with the repo you'd like to push your build to. You can also add more supported architectures
in addition to the amd64 and armv7 ones

在计算机发展的历史上，没有哪一种程序设计语言像C语言这样应用广泛。本书是C语言的设计者之一Dennis M.Ritchie和著名计算机科学家Brian W.Kernighan合著的一本介绍C语言的权威经典著作。我们现在见到的大量论述C语言程序设计的教材和专著均以此书为蓝本。本书第1版中介绍的C语言成为后来广泛使用的C语言版本——标准C的基础。人们熟知的“hello,World"程序就是由本书首次引......一起来看看 《C程序设计语言》 这本书的介绍吧!
