What is Certbot?

Certbot is a fully-featured, extensible client for the Let's Encrypt CA (or any other CA that speaks the ACME protocol) that can automate the tasks of obtaining certificates and configuring webservers to use them. This client runs on Unix-based operating systems.

Until May 2016, Certbot was named simply letsencrypt or letsencrypt-auto, depending on install method. Instructions on the Internet, and some pieces of the software, may still refer to this older name.

How to use this image

The easiest way how to run Certbot image is as follow:

$ docker run --rm -it \
    -p 80:80 -p 443:443 \
    -v <store-path>:/etc/letsencrypt
    --net=<your-network-name> \
    adop/certbot:VERSION <command>

Where command is certbot command.


certbot certonly --standalone -d ${DOMAIN_NAME} --text --register-unsafely-without-email --agree-tos"

after the above, the Certbot will request SSL certificates for the $DOMAIN_NAME and save it to <store-path>.
