1. Setup DNS Records
### Setup
- A Record: `*.y.z` -> `10.0.10.1`
- AAAA Record: `*.y.z` -> `::ffff:a00:a01`
1. Pull docker image
```shell
docker pull ghcr.io/yusing/go-proxy:latest
```
2. Setup `go-proxy` [See here](docs/docker.md)
2. Create new directory, `cd` into it, then run setup
3. Configure `go-proxy`
- with text editor (i.e. Visual Studio Code)
- or with web config editor via `http://gp.y.z`
```shell
docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/go-proxy setup
```
3. Setup DNS Records point to machine which runs `go-proxy`, e.g.
- A Record: `*.y.z` -> `10.0.10.1`
- AAAA Record: `*.y.z` -> `::ffff:a00:a01`
4. Setup `docker-socket-proxy` other docker nodes _(if any)_ (see [example](docs/docker_socket_proxy.md)) and then them inside `config.yml`
5. Done. You may now do some extra configuration
- With text editor (e.g. Visual Studio Code)
- With Web UI via `gp.y.z`
- For more info, [See docker.md](docs/docker.md)

## 入門指南
### 安裝
1. 抓取Docker鏡像
```shell
docker pull ghcr.io/yusing/go-proxy:latest
```
2. 建立新的目錄,並切換到該目錄,並執行
```shell
docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/go-proxy setup
```
3. 設置 DNS 記錄,例如:
- A 記錄: `*.y.z` -> `10.0.10.1`
- AAAA 記錄: `*.y.z` -> `::ffff:a00:a01`
4. 配置 `docker-socket-proxy` 其他 Docker 節點(如有) (參見 [範例](docs/docker_socket_proxy.md)) 然後加到 `config.yml` 中
5. 大功告成,你可以做一些額外的配置
- 使用文本編輯器 (推薦 Visual Studio Code [參見 VSCode 使用 schema](#vscode-中使用-json-schema))
- 或通過 `http://gp.y.z` 使用網頁配置編輯器
- 詳情請參閱 [docker.md](docs/docker.md)

- [Services URLs for above examples](#services-urls-for-above-examples)
## Setup
## Additional setup
1. Install `wget` if not already
1. Enable HTTPs _(optional)_
2. Run setup script
Mount a folder to store obtained certs or to load existing cert
`bash <(wget -qO- https://github.com/yusing/go-proxy/raw/main/setup-docker.sh)`
```yaml
services:
go-proxy:
...
volumes:
- ./certs:/app/certs
```
What it does:
To use **autocert**, complete that section in `config.yml`, e.g.
- Create required directories
- Setup `config.yml` and `compose.yml`
```yaml
autocert:
email: john.doe@x.y.z # ACME Email
domains: # a list of domains for cert registration
- y.z
- *.y.z
provider: cloudflare
options:
auth_token: c1234565789-abcdefghijklmnopqrst # your zone API token
```
3. Verify folder structure and then `cd go-proxy`
To use **existing certificate**, set path for cert and key in `config.yml`, e.g.
```plain
go-proxy
├── certs
├── compose.yml
└── config
├── config.yml
└── providers.yml
```
```yaml
autocert:
provider: local
cert_path: /app/certs/cert.crt
key_path: /app/certs/priv.key
```
4. Enable HTTPs _(optional)_
2. Modify `compose.yml` to fit your needs
- To use autocert feature
3. Run `docker compose up -d` to start the container
- completing `autocert` section in `config/config.yml`
- mount `certs/` to `/app/certs` to store obtained certs
- To use existing certificate
mount your wildcard (`*.y.z`) SSL cert
- cert / chain / fullchain -> `/app/certs/cert.crt`
- private key -> `/app/certs/priv.key`
5. Modify `compose.yml` fit your needs
Add networks to make sure it is in the same network with other containers, or make sure `proxy.<alias>.host` is reachable
6. Run `docker compose up -d` to start the container
7. Start editing config files in `http://<ip>:8080`
4. Navigate to Web panel `http://gp.yourdomain.com` or use **Visual Studio Code (provides schema check)** to edit proxy config

- `scheme`: proxy protocol
- default:
- if `port` is like `x:y`: `tcp`
- if `port` is a number: `http`
- allowed: `http`, `https`, `tcp`, `udp`
- `host`: proxy host
- default: `container_name`
- allowed: IP address, hostname
- `port`: proxy port
- default: first port in `ports:`
- `http(s)`: number in range og `0 - 65535`
- `tcp`, `udp`: `x:y`
- `x`: port for `go-proxy` to listen on
- `y`: port, or _service name_ of target container
see [constants.go:14 for _service names_](../src/common/constants.go#L74)

2. apps.y.z./webdav/path/to/file -> webdav:80/path/to/file
- `forward`: path remain unchanged
1. apps.y.z/webdav -> webdav:80/webdav

#### Key-value mapping example
- `set_headers`: a list of header to set, (key:value, one by line)
Docker Compose
Duplicated keys will be treated as multiple-value headers
```yaml
services:
nginx:
...
labels:
proxy.nginx.middlewares.modify_request.set_headers: | # remember to add the '|'
X-Custom-Header1: value1, value2
X-Custom-Header2: value3, value4

X-Custom-Header1: value2
X-Custom-Header2: value2
```
File Provider
- `hide_headers`: comma seperated list of headers to hide
```yaml
service_a:
host: service_a.internal
middlewares:

## Troubleshooting
- Firewall issues
- Container not showing up in proxies list
If you are using `ufw` with vpn that drop all inbound traffic except vpn, run below:
Please check that either `ports` or label `proxy.<alias>.port` is declared, e.g.
`sudo ufw allow from 172.16.0.0/16 to 100.64.0.0/10`
```yaml
services:
nginx-1: # Option 1
...
ports:
- 80
nginx-2: # Option 2
...
container_name: nginx-2
network_mode: host
labels:
proxy.nginx-2.port: 80
```
Explaination:
- Firewall issues
Docker network is usually `172.16.0.0/16`
If you are using `ufw` with vpn that drop all inbound traffic except vpn, run below:
Tailscale is used as an example, `100.64.0.0/10` will be the CIDR
`sudo ufw allow from 172.16.0.0/16 to 100.64.0.0/10`
You can also list CIDRs of all docker bridge networks by:
Explaination:
`docker network inspect $(docker network ls | awk '$3 == "bridge" { print $1}') | jq -r '.[] | .Name + " " + .IPAM.Config[0].Subnet' -`

## Available middlewares
### Redirect http
Redirect http requests to https
```yaml
# docker labels
proxy.app1.middlewares.redirect_http:
# include file
app1:
middlewares:
redirect_http:
```
nginx equivalent:
```nginx
server {
listen 80;
server_name domain.tld;
return 301 https://$host$request_uri;
}
```
[🔼Back to top](#table-of-content)
### Custom error pages
To enable custom error pages, mount a folder containing your `html`, `js`, `css` files to `/app/error_pages` of _go-proxy_ container **(subfolders are ignored, please place all files in root directory)**
Any path under `error_pages` directory (e.g. `href` tag), should starts with `/$gperrorpage/`
Example:
```html
<html>
<head>
<title>404 Not Found</title>
<link type="text/css" rel="stylesheet" href="/$gperrorpage/style.css" />
</head>
<body>
...
</body>
</html>
```
Hot-reloading is **supported**, you can **edit**, **rename** or **delete** files **without restarting**. Changes will be reflected after page reload
Error page will be served if:
- route does not exist or domain does not match any of `match_domains`
or
- status code is not in range of 200 to 300, and
- content type is `text/html`, `application/xhtml+xml` or `text/plain`
Error page will be served:
- from file `<statusCode>.html` if exists
- otherwise from `404.html`
- if they don't exist, original response will be served
```yaml
# docker labels
proxy.app1.middlewares.custom_error_page:
# include file
app1:
middlewares:
custom_error_page:
