LetsEncrypt

Create 90 days SSL certificates for given domains.

How it works

Container creates simple Nginx server listening on port 80 and waiting for letsencrypt validation.

It handles only requests to mydomain.com/.well-known, all other requests are forbidden.

server {
    listen 80;
    server_name $DOMAINS;

    location ^~ /.well-known/ {
        root /var/www/acme-certs;
    }

    location / {
        return 403;
    }
}

Usage

docker run \
    -p 80:80 \ 
    -v /srv/certs/mydomain.com:/var/www/certs \
    --name le \
    -e DOMAINS='mydomain.com www.mydomain.com' \
    -e EMAIL='my@email.tld' \
    dockette/letsencrypt:latest

You can add -it for interactive shell.

After that you will have copies of certificates in your /srv/certs/mydomain.com/ folder.
