ArvanCloud hook for dehydrated

This is a hook for the Let's Encrypt ACME client dehydrated (previously known as letsencrypt.sh) that allows you to use ArvanCloud DNS records to respond to dns-01 challenges. Requires Python and your ArvanCloud account e-mail and password being in the environment.

Installation

$ cd ~
$ git clone https://github.com/lukas2511/dehydrated
$ cd dehydrated
$ mkdir hooks
$ git clone https://github.com/hamravesh/dehydrated-arvancloud-hook.git hooks/arvancloud

If you are using Python 3:

$ pip install -r hooks/arvancloud/requirements.txt

Otherwise, if you are using Python 2 (make sure to also check the urllib3 documentation for possible caveats):

$ pip install -r hooks/arvancloud/requirements-python-2.txt

Configuration

Your account's ArvanCloud email and password are expected to be in the environment, so make sure to:

$ export ARVAN_EMAIL='user@example.com'
$ export ARVAN_PASSWORD='your-password'

Optionally, you can specify the DNS servers to be used for propagation checking via the ARVAN_DNS_SERVERS environment variable (props bennettp123):

$ export ARVAN_DNS_SERVERS='8.8.8.8 8.8.4.4'

If you want more information about what is going on while the hook is running:

$ export ARVAN_DEBUG='true'

Alternatively, these statements can be placed in dehydrated/config, which is automatically sourced by dehydrated on startup:

echo "export ARVAN_EMAIL=user@example.com" >> config
echo "export ARVAN_KEY=your-password" >> config
echo "export ARVAN_DEBUG=true" >> config

Usage

$ ./dehydrated -c -d example.com -t dns-01 -k 'hooks/arvancloud/hook.py'
