# Quickstart guide
## Reverse proxy
The following environment variables can be used to deploy bunkerized-nginx as a reverse proxy in front of your web services :
- `USE_REVERSE_PROXY` : activate/deactivate the reverse proxy mode
- `REVERSE_PROXY_URL` : public path prefix
- `REVERSE_PROXY_HOST` : full address of the proxied service
Here is a basic example :
```conf
SERVER_NAME=www.example.com
USE_REVERSE_PROXY=yes
REVERSE_PROXY_URL=/
REVERSE_PROXY_HOST=http://my-service.example.local:8080
```
If you have multiple web services you can configure multiple reverse proxy rules by appending a number to the environment variables names :
```conf
SERVER_NAME=www.example.com
USE_REVERSE_PROXY=yes
REVERSE_PROXY_URL_1=/app1
REVERSE_PROXY_HOST_1=http://app1.example.local:8080
REVERSE_PROXY_URL_2=/app2
REVERSE_PROXY_HOST_2=http://app2.example.local:8080
```
### Docker
When using Docker, the recommended way is to create a network so bunkerized-nginx can communicate with the web service using the container name :
```shell
$ docker network create services-net
$ docker run -d \
--name myservice \
--network services-net \
tutum/hello-world
$ docker run -d \
--network services-net \
-p 80:8080 \
-p 443:8443 \
-v "${PWD}/certs:/etc/letsencrypt" \
-e SERVER_NAME=www.example.com \
-e AUTO_LETS_ENCRYPT=yes \
-e USE_REVERSE_PROXY=yes \
-e REVERSE_PROXY_URL=/ \
-e REVERSE_PROXY_HOST=http://myservice \
bunkerity/bunkerized-nginx
```
docker-compose equivalent :
```yaml
version: '3'
services:
mybunkerized:
image: bunkerity/bunkerized-nginx
ports:
- 80:8080
- 443:8443
volumes:
- ./certs:/etc/letsencrypt
environment:
- SERVER_NAME=www.example.com
- AUTO_LETS_ENCRYPT=yes
- USE_REVERSE_PROXY=yes
- REVERSE_PROXY_URL=/
- REVERSE_PROXY_HOST=http://myservice
networks:
- services-net
depends_on:
- myservice
myservice:
image: tutum/hello-world
networks:
- services-net
networks:
services-net:
```
### Docker autoconf
When the Docker autoconf stack is running, you simply need to start the container hosting your web service and add the environment variables as labels :
```shell
$ docker run -d \
--name myservice \
--network services-net \
-l bunkerized-nginx.SERVER_NAME=www.example.com \
-l bunkerized-nginx.USE_REVERSE_PROXY=yes \
-l bunkerized-nginx.REVERSE_PROXY_URL=/ \
-l bunkerized-nginx.REVERSE_PROXY_HOST=http://myservice \
tutum/hello-world
```
docker-compose equivalent :
```yaml
version: '3'
services:
myservice:
image: tutum/hello-world
networks:
services-net:
aliases:
- myservice
labels:
- bunkerized-nginx.SERVER_NAME=www.example.com
- bunkerized-nginx.USE_REVERSE_PROXY=yes
- bunkerized-nginx.REVERSE_PROXY_URL=/
- bunkerized-nginx.REVERSE_PROXY_HOST=http://myservice
networks:
services-net:
external:
name: services-net
```
### Docker Swarm
When the Docker Swarm stack is running, you simply need to start the Swarm service hosting your web service and add the environment variables as labels :
```shell
$ docker service create \
--name myservice \
--network services-net \
--constraint node.role==worker \
-l bunkerized-nginx.SERVER_NAME=www.example.com \
-l bunkerized-nginx.USE_REVERSE_PROXY=yes \
-l bunkerized-nginx.REVERSE_PROXY_URL=/ \
-l bunkerized-nginx.REVERSE_PROXY_HOST=http://myservice \
tutum/hello-world
```
docker-compose equivalent :
```yaml
version: '3'
services:
myservice:
image: tutum/hello-world
networks:
services-net:
aliases:
- myservice
deploy:
placement:
constraints:
- "node.role==worker"
labels:
- bunkerized-nginx.SERVER_NAME=www.example.com
- bunkerized-nginx.USE_REVERSE_PROXY=yes
- bunkerized-nginx.REVERSE_PROXY_URL=/
- bunkerized-nginx.REVERSE_PROXY_HOST=http://myservice
networks:
services-net:
external:
name: services-net
```
### Kubernetes
Example deployment and service declaration :
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: myservice
labels:
app: myservice
spec:
replicas: 1
selector:
matchLabels:
app: myservice
template:
metadata:
labels:
app: myservice
spec:
containers:
- name: myservice
image: tutum/hello-world
---
apiVersion: v1
kind: Service
metadata:
name: myservice
spec:
type: ClusterIP
selector:
app: myservice
ports:
- protocol: TCP
port: 80
targetPort: 80
```
The most straightforward way to add a reverse proxy in the Kubernetes cluster is to declare it in the Ingress resource :
```yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: bunkerized-nginx-ingress
# this label is mandatory
labels:
bunkerized-nginx: "yes"
spec:
tls:
- hosts:
- www.example.com
rules:
- host: "www.example.com"
http:
paths:
- pathType: Prefix
path: "/"
backend:
service:
name: myservice
port:
number: 80
```
An alternative "hackish" way is to use environment variables as annotations prefixed with "bunkerized-nginx." inside the Service resource of your web service :
```yaml
apiVersion: v1
kind: Service
metadata:
name: myservice
# this label is mandatory
labels:
bunkerized-nginx: "yes"
annotations:
bunkerized-nginx.SERVER_NAME: "www.example.com"
bunkerized-nginx.AUTO_LETS_ENCRYPT: "yes"
bunkerized-nginx.USE_REVERSE_PROXY: "yes"
bunkerized-nginx.REVERSE_PROXY_URL: "/"
bunkerized-nginx.REVERSE_PROXY_HOST: "http://myservice.default.svc.cluster.local"
spec:
type: ClusterIP
selector:
app: myservice
ports:
- protocol: TCP
port: 80
targetPort: 80
```
### Linux
Example of a basic configuration file :
```conf
HTTP_PORT=80
HTTPS_PORT=443
SERVER_NAME=www.example.com
AUTO_LETS_ENCRYPT=yes
USE_REVERSE_PROXY=yes
REVERSE_PROXY_URL=/
# Local proxied application
REVERSE_PROXY_HOST=http://127.0.0.1:8080
# Remote proxied application
#REVERSE_PROXY_HOST=http://service.example.local:8080
```
## PHP applications
The following environment variables can be used to configure bunkerized-nginx in front of PHP-FPM web applications :
- `REMOTE_PHP` : host/ip of a remote PHP-FPM instance
- `REMOTE_PHP_PATH` : absolute path containing the PHP files (from the remote instance perspective)
- `LOCAL_PHP` : absolute path of the local unix socket used by a local PHP-FPM instance
- `LOCAL_PHP_PATH` : absolute path containing the PHP files (when using local instance)
Here is a basic example with a remote instance :
```conf
SERVER_NAME=www.example.com
REMOTE_PHP=my-php.example.local
REMOTE_PHP_PATH=/var/www/html
```
And another example with a local instance :
```conf
SERVER_NAME=www.example.com
LOCAL_PHP=/var/run/php7-fpm.sock
LOCAL_PHP_PATH=/opt/bunkerized-nginx/www
```
### Docker
When using Docker, the recommended way is to create a network so bunkerized-nginx can communicate with the PHP-FPM instance using the container name :
```shell
$ docker network create services-net
$ docker run -d \
--name myservice \
--network services-net \
-v "${PWD}/www:/app" \
php:fpm
$ docker run -d \
--network services-net \
-p 80:8080 \
-p 443:8443 \
-v "${PWD}/www:/www:ro" \
-v "${PWD}/certs:/etc/letsencrypt" \
-e SERVER_NAME=www.example.com \
-e AUTO_LETS_ENCRYPT=yes \
-e REMOTE_PHP=myservice \
-e REMOTE_PHP_PATH=/app \
bunkerity/bunkerized-nginx
```
docker-compose equivalent :
```yaml
version: '3'
services:
mybunkerized:
image: bunkerity/bunkerized-nginx
ports:
- 80:8080
- 443:8443
volumes:
- ./www:/www:ro

environment:
- SERVER_NAME=www.example.com
- AUTO_LETS_ENCRYPT=yes
- REMOTE_PHP=myservice
- REMOTE_PHP_PATH=/app
networks:

depends_on:
- myservice
myservice:
image: php:fpm
networks:
- services-net
volumes:
- ./www:/app
networks:
services-net:
```
### Docker autoconf
When the Docker autoconf stack is running, you simply need to start the container hosting your PHP-FPM instance and add the environment variables as labels :
```shell
$ docker run -d \
--name myservice \
--network services-net \
-v "${PWD}/www/www.example.com:/app" \
-l bunkerized-nginx.SERVER_NAME=www.example.com \
-l bunkerized-nginx.REMOTE_PHP=myservice \
-l bunkerized-nginx.REMOTE_PHP_PATH=/app \

- bunkerized-nginx.REMOTE_PHP_PATH=/app
networks:
services-net:
external:
name: services-net
```
### Docker Swarm
When the Docker Swarm stack is running, you simply need to start the Swarm service hosting your PHP-FPM instance and add the environment variables as labels :
```shell
$ docker service create \
--name myservice \
--constraint node.role==worker \
--network services-net \
--mount type=bind,source=/shared/www/www.example.com,destination=/app \
-l bunkerized-nginx.SERVER_NAME=www.example.com \
-l bunkerized-nginx.REMOTE_PHP=myservice \
-l bunkerized-nginx.REMOTE_PHP_PATH=/app \
php:fpm
```
docker-compose equivalent :
```yaml
version: "3"
services:
myservice:
image: php:fpm
networks:
services-net:
aliases:
- myservice
volumes:
- /shared/www/www.example.com:/app

- "bunkerized-nginx.REMOTE_PHP=myservice"
- "bunkerized-nginx.REMOTE_PHP_PATH=/app"
networks:
services-net:
external:

```
### Kubernetes
You need to use environment variables as annotations prefixed with `bunkerized-nginx.` inside the Service resource of your PHP-FPM instance :
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: myservice
labels:
app: myservice
spec:
replicas: 1
selector:

image: php:fpm
volumeMounts:
- name: php-files
mountPath: /app
volumes:
- name: php-files
hostPath:
path: /shared/www/www.example.com
type: Directory
---
apiVersion: v1
kind: Service
metadata:
name: myservice
# this label is mandatory
labels:
bunkerized-nginx: "yes"
annotations:
bunkerized-nginx.SERVER_NAME: "www.example.com"
bunkerized-nginx.AUTO_LETS_ENCRYPT: "yes"
bunkerized-nginx.REMOTE_PHP: "myservice.default.svc.cluster.local"
bunkerized-nginx.REMOTE_PHP_PATH: "/app"
spec:
type: ClusterIP
selector:
app: myservice
ports:
- protocol: TCP
port: 9000
targetPort: 9000
```
### Linux
Example of a basic configuration file :
```conf
HTTP_PORT=80
HTTPS_PORT=443
SERVER_NAME=www.example.com
AUTO_LETS_ENCRYPT=yes
# Case 1 : the PHP-FPM instance is on the same machine
# you just need to adjust the socket path
LOCAL_PHP=/run/php/php7.3-fpm.sock
LOCAL_PHP_PATH=/opt/bunkerized-nginx/www
# Case 2 : the PHP-FPM instance is on another machine
#REMOTE_PHP=myapp.example.local
#REMOTE_PHP_PATH=/app
```
## Multisite
If you have multiple services to protect, the easiest way to do it is by enabling the "multisite" mode. When using multisite, bunkerized-nginx will create one server block per server defined in the `SERVER_NAME` environment variable. You can configure each servers independently by adding the server name as a prefix.
Here is an example :
```conf
SERVER_NAME=app1.example.com app2.example.com
MULTISITE=yes
app1.example.com_USE_REVERSE_PROXY=yes
app1.example.com_REVERSE_PROXY_URL=/
app1.example.com_REVERSE_PROXY_HOST=http://app1.example.local:8080
app2.example.com_REMOTE_PHP=app2.example.local
app2.example.com_REMOTE_PHP_PATH=/var/www/html
```
When using the multisite mode, some [special folders](https://bunkerized-nginx.readthedocs.io/en/latest/special_folders.html) must have a specific structure with subfolders named the same as the servers defined in the `SERVER_NAME` environment variable. Let's take the **app2.example.com** as an example : if some static files need to be served by nginx, you need to place them under **www/app2.example.com**.
### Docker
When using Docker, the recommended way is to create a network so bunkerized-nginx can communicate with the web services using the container name :
```shell
$ docker network create services-net
$ docker run -d \
--name myapp1 \
--network services-net \
tutum/hello-world
$ docker run -d \
--name myapp2 \
--network services-net \
-v "${PWD}/www/app2.example.com:/app" \
php:fpm
$ docker run -d \
--network services-net \
-p 80:8080 \
-p 443:8443 \
-v "${PWD}/www:/www:ro" \
-v "${PWD}/certs:/etc/letsencrypt" \
-e "SERVER_NAME=app1.example.com app2.example.com" \
-e MULTISITE=yes \
-e AUTO_LETS_ENCRYPT=yes \
-e app1.example.com_USE_REVERSE_PROXY=yes \
-e app1.example.com_REVERSE_PROXY_URL=/ \
-e app1.example.com_REVERSE_PROXY_HOST=http://myapp1 \
-e app2.example.com_REMOTE_PHP=myapp2 \
