Starting a container

docker run --name ns-letsencrypt \
        --mount type=bind,source=<path to data>,target=/root \
        --mount type=bind,source=/etc/localtime,destination=/etc/localtime,readonly \
        xawen/ns-letsencrypt

Configuration

Once the container is running, get the container ID

$ docker ps

Then, open a shell into it:

$ docker exec -it <contaner ID> bash

At that point, follow the diretions on Ryan's page. Note that following steps are unnecessary as they're already in the image:

• Configure Linux Server: apt-get install python git python-pip curl
• Configure Linux Server: pip install requests
• Configure Linux Server: git clone --recursive https://github.com/ryancbutler/ns-letsencrypt
• Automate Renewal: All steps

The container will create a cron job that will run once per week (3am on Saturday). The ns_letsencrypt script will update the LE certificate once it's within 30 days of expiration.
