# Nginx Kit
|
|
|
|
## Start
|
|
|
|
```bash
|
|
git clone https://git.forge.st/ops/nginx-kit.git /opt/nginx-kit
|
|
ln -s /opt/nginx-kit /etc/nginx/kit
|
|
```
|
|
|
|
### Update
|
|
|
|
```bash
|
|
cd /opt/nginx-kit
|
|
git pull
|
|
nginx -t
|
|
systemctl reload nginx
|
|
```
|
|
|
|
## Contexts
|
|
|
|
This repository is organized by nginx context:
|
|
|
|
- `http/`: snippets that must be included inside `http {}`.
|
|
- `ssl/`: HTTPS and TLS snippets for `server {}` blocks.
|
|
- `proxy_pass/`: reverse proxy snippets for `location {}` blocks.
|
|
- `redirect/`: host and canonical URL redirects for `server {}` blocks.
|
|
- `templates/`: copy-and-edit starter snippets such as certificates.
|
|
- `examples/`: working examples showing how to compose the snippets.
|
|
|
|
## Common combinations
|
|
|
|
### HTTPS site
|
|
|
|
Include these inside a `server {}` block:
|
|
|
|
```nginx
|
|
server {
|
|
# ...
|
|
include snippets/cert/mydomain.com.conf;
|
|
include kit/security.conf;
|
|
include kit/ssl/security.conf;
|
|
include kit/ssl/hsts.conf;
|
|
include kit/ssl/force.conf;
|
|
# ...
|
|
}
|
|
```
|
|
|
|
See [examples/example.com.conf](examples/example.com.conf:1) for the full server-level example.
|
|
|
|
### Reverse proxy with websocket support
|
|
|
|
Websocket proxying needs one `http {}`-level `map` plus `location {}`-level proxy snippets:
|
|
|
|
```nginx
|
|
http {
|
|
include kit/http/websocket-map.conf;
|
|
|
|
server {
|
|
# ...
|
|
location / {
|
|
include kit/proxy_pass/forwarded.conf;
|
|
include kit/proxy_pass/timeout-300.conf;
|
|
proxy_pass http://app_backend;
|
|
}
|
|
|
|
location /ws/ {
|
|
include kit/proxy_pass/forwarded.conf;
|
|
include kit/proxy_pass/websocket.conf;
|
|
include kit/proxy_pass/timeout-300.conf;
|
|
proxy_pass http://app_backend;
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
See [examples/reverse-proxy.nginx.conf](examples/reverse-proxy.nginx.conf:1) for a complete standalone config.
|
|
|
|
## Templates
|
|
|
|
### SSL certs
|
|
|
|
```bash
|
|
cd /etc/nginx
|
|
mkdir -p snippets/cert
|
|
cp kit/templates/cert/example.com.conf snippets/cert/mydomain.com.conf
|
|
vi snippets/cert/mydomain.com.conf
|
|
```
|
|
|
|
Replace the certificate paths with yours, then include the snippet in your `server {}` block:
|
|
|
|
```nginx
|
|
server {
|
|
# ...
|
|
include snippets/cert/mydomain.com.conf;
|
|
include kit/security.conf;
|
|
include kit/ssl/security.conf;
|
|
include kit/ssl/hsts.conf;
|
|
# ...
|
|
}
|
|
```
|
|
|
|
## Snippet reference
|
|
|
|
- `kit/http/websocket-map.conf`: defines `$connection_upgrade` for websocket proxying. Must be included inside `http {}`.
|
|
- `kit/security.conf`: common security headers and host normalization. Intended for `server {}`.
|
|
- `kit/ssl/security.conf`: TLS protocol and session resumption settings. Intended for `server {}`.
|
|
- `kit/ssl/hsts.conf`: HSTS header for HTTPS responses. Intended for `server {}`.
|
|
- `kit/ssl/hsts-preload.conf`: HSTS variant with `preload`. Use only if the whole domain tree is preload-safe.
|
|
- `kit/ssl/force.conf`: redirects HTTP requests to HTTPS. Intended for `server {}`.
|
|
- `kit/redirect/to-primary-domain.conf`: redirects aliases to the primary `server_name`. Intended for `server {}`.
|
|
- `kit/proxy_pass/forwarded.conf`: standard reverse proxy headers. Intended for `location {}`.
|
|
- `kit/proxy_pass/websocket.conf`: websocket upgrade headers. Requires `kit/http/websocket-map.conf`.
|
|
- `kit/proxy_pass/timeout-300.conf`: longer proxy timeouts. Intended for `location {}`.
|
|
|
|
## Validation
|
|
|
|
Run the Docker-based syntax checks from the repo root:
|
|
|
|
```powershell
|
|
./scripts/validate-docker.ps1
|
|
```
|
|
|
|
The script validates:
|
|
|
|
- [examples/example.com.conf](examples/example.com.conf:1) as a server-level snippet.
|
|
- [examples/reverse-proxy.nginx.conf](examples/reverse-proxy.nginx.conf:1) as a complete nginx config.
