ssh-proxy-by-caddy-l4

Layer 4 proxy server, Powered by Caddy.

Concept

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

Warning

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

Run

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

Test

ssh -T -p 2201 git@localhost

Usage

git clone git@localhost:initdc/Hello_World.git

Build

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/riscv64,linux/ppc64le,linux/s390x,linux/386,linux/mips64le,linux/mips64,linux/arm/v7,linux/arm/v6 -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.

   check full list with docker buildx ls
