Hello,

Using dehydrated v0.5.0, my script works well for a year +. All subdomains are hosted on the same servers (share the same nfs mount)

Now I have to add a new subdomain (say sub.domain.com) in the domains.txt which is hosted on another server. For the challenge i have added a hook script with the --hook parameter to transfert the challenge token.

./dehydrated --register --accept-terms --hook /some/path/letsencrypt-install-hook.sh
./dehydrated -c

/some/path/letsencrypt-install-hook.sh :

#!/bin/sh

deploy_challenge() {
    local DOMAIN="${1}" TOKEN_FILENAME="${2}" TOKEN_VALUE="${3}"
    
    # This hook is called once for every domain that needs to be
    # validated, including any alternative names you may have listed.
    #
    # Parameters:
    # - DOMAIN
    #   The domain name (CN or subject alternative name) being
    #   validated.
    # - TOKEN_FILENAME
    #   The name of the file containing the token to be served for HTTP
    #   validation. Should be served by your web server as
    #   /.well-known/acme-challenge/${TOKEN_FILENAME}.
    # - TOKEN_VALUE
    #   The token value that needs to be served for validation. For DNS
    #   validation, this is what you want to put in the _acme-challenge
    #   TXT record. For HTTP validation it is the value that is expected
    #   be found in the $TOKEN_FILENAME file.
    
    echo "Calling deploy_challenge() hook for ${DOMAIN}"

    if [[ "${DOMAIN:-}" = "sub.domain.com" ]]; then
        echo "Copy challenge token to sub.domain.com with scp..."
        scp [...]
    fi
}

HANDLER="$1"; shift
if [[ "${HANDLER}" =~ ^(deploy_challenge|clean_challenge|deploy_cert|unchanged_cert|invalid_challenge|request_failure|startup_hook|exit_hook)$ ]]; then
  "$HANDLER" "$@"
fi

The hook is not called (I dont see the echos in the log)
Am I missing something?
Thanks

You don't need the --hook parameter on the register command. You do need it on the cron command. Like so:

./dehydrated --register --accept-terms
./dehydrated -c --hook /some/path/letsencrypt-install-hook.sh

You may also find it useful to add the hook to the main config file (if it works for your normal domains as well) or to a per-certificate config file (if you only want it to run for this one certificate).

Works as expected, i also had to include all the hook functions in the hook script.
Thanks!
