Layer 4 proxy server, Powered by Caddy.

Solving git@github.com network problem in this case.

![DANGER] Private key will send to mirror server, deploy server by yourself

docker run --name caddy-l4 -dp 2201:2201 initdc/caddy-l4:latest

You need set private key and port for ssh

# ~/.ssh/config Host github.com Hostname github.com IdentityFile ~/.ssh/id_ed25519_github User git Host localhost Hostname localhost IdentityFile ~/.ssh/id_ed25519_github Port 2201 User git # ssh.example.com Host ssh.example.com Hostname ssh.example.com IdentityFile ~/.ssh/id_ed25519_github User git

ssh -T -p 2201 git@localhost

git clone git@localhost:initdc/Hello_World.git

change buildx DRIVER from docker to docker-container

docker buildx create --name mybuilder --driver-opt network=host --use docker buildx inspect --bootstrap

1. local

   docker buildx build -t caddy-l4:amd64 . --load

   docker buildx build --platform linux/arm64 -t caddy-l4:arm64 . --load

   -t for local tag: name:arch

2. for pushing

   docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t initdc/caddy-l4:v$(TZ=Asia/Shanghai date +%Y.%m.%d) . --push

   latest -> v$(TZ=Asia/Shanghai date +%Y.%m.%d)

   replace initdc with your docker registry user name.

   exclude linux/riscv64,linux/ppc64le,linux/s390x,linux/386,linux/mips64le,linux/mips64,linux/arm/v6 for my own usage, add more by yourself.

   check full list with docker buildx ls
