# go-proxy
|
||||||
|
|
||||||
|
A simple auto docker reverse proxy for home use.
|
||||||
|
|
||||||
|
Written in **Go** with *~180 loc*.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- subdomain matching **(domain name doesn't matter)**
|
||||||
|
- path matching
|
||||||
|
- Auto hot-reload when container start / die / stop.
|
||||||
|
|
||||||
|
## Why am I making this
|
||||||
|
|
||||||
|
I have tried different reverse proxy services, i.e. [nginx proxy manager](https://nginxproxymanager.com/), [traefik](https://github.com/traefik/traefik), [nginx-proxy](https://github.com/nginx-proxy/nginx-proxy). I have found that `traefik` is not easy to use, and I don't want to click buttons every time I spin up a new container (`nginx proxy manager`). For `nginx-proxy` I found it buggy and quite unusable.
|
||||||
|
|
||||||
|
## How to use
|
||||||
|
|
||||||
|
1. Clone the repo `git clone https://github.com/yusing/go-proxy`
|
||||||
|
|
||||||
|
2. Copy [compose.example.yml](compose.example.yml) to `compose.yml`
|
||||||
|
|
||||||
|
3. add networks to make sure it is in the same network with other containers, or make sure `proxy.<alias>.host` is reachable
|
||||||
|
|
||||||
|
4. modify the path to your SSL certs. See [Getting SSL Certs](#getting-ssl-certs)
|
||||||
|
|
||||||
|
5. start `go-proxy` with `docker compose up -d`.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
With a proper container name, no label needs to be added.
|
||||||
|
|
||||||
|
However, there are some labels you can manipulate with:
|
||||||
|
|
||||||
|
- `proxy.aliases`: comma separated aliases for subdomain matching
|
||||||
|
- defaults to `container_name`
|
||||||
|
- `proxy.<alias>.scheme`: container port protocol (`http` or `https`)
|
||||||
|
- defaults to `http`
|
||||||
|
- `proxy.<alias>.host`: proxy host
|
||||||
|
- defaults to `container_name`
|
||||||
|
- `proxy.<alias>.port`: proxy port
|
||||||
|
- defaults to first expose port (declared in `Dockerfile` or `docker-compose.yml`)
|
||||||
|
- `proxy.<alias>.path`: path matching
|
||||||
|
- defaults to empty
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
version: '3'
|
||||||
|
services:
|
||||||
|
whoami:
|
||||||
|
image: traefik/whoami
|
||||||
|
container_name: whoami
|
||||||
|
# visit https://whoami.yourdomain.com to access
|
||||||
|
|
||||||
|
# enable both subdomain and path matching:
|
||||||
|
whoami:
|
||||||
|
image: traefik/whoami
|
||||||
|
container_name: whoami
|
||||||
|
labels:
|
||||||
|
- proxy.aliases=whoami,apps
|
||||||
|
- proxy.apps.path=/whoami
|
||||||
|
# 1. visit https://whoami.yourdomain.com to access
|
||||||
|
# 2. visit https://apps.yourdomain.com/whoami to access
|
||||||
|
```
|
||||||
|
|
||||||
|
For multiple port container (i.e. minio)
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
version: '3'
|
||||||
|
services:
|
||||||
|
minio:
|
||||||
|
image: quay.io/minio/minio
|
||||||
|
container_name: minio
|
||||||
|
command:
|
||||||
|
- server
|
||||||
|
- /data
|
||||||
|
- --console-address
|
||||||
|
- "9001"
|
||||||
|
env_file: minio.env
|
||||||
|
expose:
|
||||||
|
- 9000
|
||||||
|
- 9001
|
||||||
|
volumes:
|
||||||
|
- ./data/minio/data:/data
|
||||||
|
labels:
|
||||||
|
proxy.aliases: minio,minio-console
|
||||||
|
proxy.minio.port: 9000
|
||||||
|
proxy.minio-console.port: 9001
|
||||||
|
|
||||||
|
# visit https://minio.yourdomain.com to access minio
|
||||||
|
# visit https://minio-console.yourdomain.com/whoami to access minio console
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
Q: How to fix when it shows "no matching route for subdomain \<subdomain>"?
|
||||||
|
|
||||||
|
A: Make sure the container is running, and \<subdomain> matches any container name / alias
|
||||||
|
|
||||||
|

|
## Build it yourself
|
||||||
|
|
||||||
|
1. [Install go](https://go.dev/doc/install) if not already
|
||||||
|
|
||||||
|
2. Get dependencies with `go get`
|
||||||
|
|
||||||
|
3. build image with following commands
|
||||||
|
|
||||||
|
```shell
|
||||||
|
mkdir -p bin
|
||||||
|
CGO_ENABLED=0 GOOS=<platform> go build -o bin/go-proxy
|
||||||
|
docker build -t <tag> .
|
||||||
|
```
|
||||||
|
|
||||||
|
## Getting SSL certs
|
||||||
|
|
||||||
|
I personally use `nginx-proxy-manager` to get SSL certs with auto renewal by Cloudflare DNS challenge. You may symlink the certs from `nginx-proxy-manager` to somewhere else, and mount them to `go-proxy`'s `/certs`
