How to secure Nginx with Let’s Encrypt certificate on Alpine Linux

by

To secure Nginx with a Let’s Encrypt SSL certificate on Alpine Linux, you can use the certbot tool. Here are the steps:

  1. Install certbot:
apk add certbot
  1. Obtain a SSL certificate:
certbot certonly --standalone -d example.com
  1. Update Nginx configuration to use the SSL certificate:

Add the following lines to the Nginx server block configuration file, typically located at /etc/nginx/nginx.conf:

server {
listen 443 ssl;
server_name example.com;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
...
}
  1. Restart Nginx to apply the changes:
/etc/init.d/nginx restart

Now Nginx should be secured with a Let’s Encrypt SSL certificate on your Alpine Linux system. Remember to renew the SSL certificate before it expires by running the following command:

certbot renew
