Nginx with Letsencrypt using Docker

Set up environment values

PS > $env:email = "[email protected]"

PS > $env:doamin = "ssl.example.com"

Run nginx with below configuration

# ./etc/nginx/conf.d/default.conf

server {
    listen 80;
    listen [::]:80;

    server_tokens off;

    location /.well-known/acme-challenge {
        root /var/www;
    }
}

PS > ./run-nginx.ps1

Get a cert from letsencrypt

PS > .\get-cert.ps1

Requesting a certificate for ssl.example.com

Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/ssl.example.com/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/ssl.example.com/privkey.pem
This certificate expires on 2022-06-24.
These files will be updated when the certificate renews.
NEXT STEPS:
- The certificate will need to be renewed before it expires. Certbot can automatically renew the certificate in the background, but you may need to take steps to enable that functionality. See https://certbot.org/renewal-setup for instructions.

Add ssl 443 setting to nginx config file

# ./etc/nginx/conf.d/default.conf

server {
    listen 80;
    listen [::]:80;

    server_tokens off;

    location /.well-known/acme-challenge {
        root /var/www;
    }
}

server {
    listen 443 ssl;
    server_name localhost;

    server_tokens off;

    ssl_certificate /etc/letsencrypt/live/ssl.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/ssl.example.com/privkey.pem;
}

Re-run nginx with new configuration

PS > ./run-nginx.ps1
