⁠What is dehydrated?

Dehydrated can be used to create and automatically renew Certificates from Letsencrypt. It requires either Port 80 to be open or a dns entry to be set for each domain. This Version contains a hook for cloudflare to automatically reset dns entries for automatic renewal.

⁠How to use this image

⁠Run crond Daemon

The crond Daemon automatically renews certificates under /etc/dehydrated/data once a day. It may be started using:

docker run --name Dehydrated \
           -e "CF_EMAIL=Cloudflare Email" \
           -e "CF_KEY=Cloudflare Global API Key" \
           --volume /path/to/dehydrated/datadir:/etc/dehydrated/data \
           --detach toendeavour/dehydrated-alpine

It requires only one volume to store the certifactes.

⁠Setup

The inital setup requires the file domains.txt inside /path/to/dehydrated/datadir. It is also necessary to register a letsencrypt account using the following:

docker run --rm \
           --volume /path/to/dehydrated/datadir:/etc/dehydrated/data \
           -it toendeavour/dehydrated-alpine \
           /usr/local/bin/dehydrated --register --accept-terms

⁠docker-compose.yml

Here is an example using docker-compose.yml:

dehydrated:
  image: toendeavour/dehydrated-alpine

  environment:
    CF_EMAIL: "Cloudflare Email"
    CF_KEY: "Cloudflare Global API Key"
