# NGINX with Proxy Generator
2+
3+
It allows us to start :
4+
5+
1. a Nginx instance
6+
2. generate proxy configurations
7+
3. generate basic auth
8+
9+
The application can be managed via:
10+
1. `manage.sh`
11+
2. or manually as explained below
12+
13+
14+
## Manage via `manage.sh`
15+
16+
```bash
17+
usage manage.sh [clean_conf | gen_default | gen_all | start | restart | reload | stop]
18+
```
19+
options:
20+
21+
1. clean_conf: remove all the configuration from `nginx/conf.d/`
22+
2. gen_default: generate only the `default.conf` file
23+
3. gen_all: generate all the configurations files from the `nginx_conf.json` file
24+
4. start: start the docker container of nginx
25+
5. restart: restart the docker container
26+
6. reload: reload the configuration in `nginx/conf.d/`
27+
7. stop: stop the container and clean the current folder
28+
29+
## Manual Configurations
30+
31+
### Reload NGINX confs
32+
33+
```bash
34+
docker exec -it <container_name> /usr/sbin/nginx -t
35+
```
36+
37+
### Start NGINX
38+
39+
```bash
40+
docker-compose up -d
41+
```
42+
43+
### Generate Proxy configurations
44+
45+
The python script `nginxify.py` can be used to generate `*.conf` files.
46+
47+
```bash
48+
49+
./nginxify.py --help
50+
51+
usage: nginxify.py [-h] [--default ONLY_DEFAULT] [--dest DEST_FOLDER]
52+
[--conf CONFS_FILE] [--overwrite OVERWRITE]
53+
54+
nginx conf generator
55+
56+
optional arguments:
57+
-h, --help show this help message and exit
58+
--default ONLY_DEFAULT
59+
if true generate only the default configurations
60+
--dest DEST_FOLDER The folder to save the *.conf files. Default value
61+
'./nginx/conf.d/'
62+
--conf CONFS_FILE The json file with the configurations. Default value
63+
'nginx_conf.json'
64+
--overwrite OVERWRITE
65+
True to overwrite all the configurations files
66+
```
67+
68+
#### Json File Structure
69+
The file contains a list of `proxies` with:
70+
- **name**: the name of the proxy
71+
- **server_names**: the name of the domain name to expose the service
72+
- **docker_name**: the name or ip address of the docker container to expose
73+
- **docker_port**: the internal port of the container
74+
- **secured**: if the service should be secured with [nginx auth_basic]()
75+
76+

114+
}
115+
]
116+
}
117+
118+
```
119+
120+
### Password generator
121+
122+
The script `password_generator.py` can be used to generate a file that stores the access passwords. By default it stores all the password in `/nginx/htpasswd/secure`. This file is mapped to the running docker container.
123+
124+
#### Usage
125+
126+
```bash
127+
./password_generator.py --help
128+
usage: password_generator.py [-h] [--file DEST_FOLDER] [--user USER]
129+
[--pwd PWD]
130+
131+
nginx auth file generator
132+
133+
optional arguments:
134+
-h, --help show this help message and exit
135+
--file DEST_FOLDER the folder to save the new username:password pair
136+
--user USER the username for the new user
137+
--pwd PWD the password for the new user
138+
```
139+
140+
### Index 404 and 50x pages
141+
142+
As default there is a custom_404 custom_50x and index page in the folder `./nginx/www/html`. If you need you can change these pages.
