Docker Image of Letsencrypt for Raspberry Pi

certbot-rpi -

@stevebargelt

Raspberry Pi (2 and 3 not 1, Zero, or Zero W) compatible Docker base image with LetsEncrypt.

As you can see above this was forked from bcecchinato/certbot-rpi - I really appreciate all of bcecchinato's work but I ran into an issue one night where I desperately needed to update my certificate on my home automation Raspberry Pi. I ran my normal docker command pulling bcecchinato's image and boom - a bug with the version of certbot that was pulled in as a submodule. Well after a bit of hair pulling I decided to fork and update the project myself. Then I decided to update the .travis.yml to grab/update the certbot submodule on every build.

• Pro: this image will always have the latest certbot bug fixes.
• Con: This image could introduce bugs from certbot master.

What is LetsEncrypt?

Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. Let’s Encrypt is a service provided by the Internet Security Research Group (ISRG).

The key principles behind Let’s Encrypt are:

• Free: Anyone who owns a domain name can use Let’s Encrypt to obtain a trusted certificate at zero cost.
• Automatic: Software running on a web server can interact with Let’s Encrypt to painlessly obtain a certificate, securely configure it for use, and automatically take care of renewal.
• Secure: Let’s Encrypt will serve as a platform for advancing TLS security best practices, both on the CA side and by helping site operators properly secure their servers.
• Transparent: All certificates issued or revoked will be publicly recorded and available for anyone to inspect.
• Open: The automatic issuance and renewal protocol will be published as an open standard that others can adopt.
• Cooperative: Much like the underlying Internet protocols themselves, Let’s Encrypt is a joint effort to benefit the community, beyond the control of any one organization.

Pull the Docker Image

Run all the commands from within the project root directory.

docker pull stevebargelt/certbot-rpi

How to use this image

To get a new certificate:

docker run -it --rm -p 443:443 --name certbot \
  -v /etc/letsencrypt:/etc/letsencrypt \
  stevebargelt/letsencrypt-rpi certonly --standalone \
  -d your.domain.com

This is only a wrapper for the official client, built on a Raspberry Pi using Hypriot. The image is rebuilt every night.

The full details for the client commands are available on Certbot GitHub project.
