Package: certbot-dns-ionos
certbot-dns-ionosIONOSDNS Authenticator plugin forCertbotThis plugin automates the process of completing adns-01challenge by
creating, and subsequently removing, TXT records using the IONOS Remote API.Configuration of IONOSIn theSystem -> Remote Usersyou have to have a user, with the following rightsClient FunctionsDNS zone functionsDNS txt functionsInstallationpip install certbot-dns-ionosNamed ArgumentsTo start using DNS authentication for ionos, pass the following arguments on
certbot’s command line:--authenticatordns-ionosselect the authenticator plugin (Required)--dns-ionos-credentialsionos Remote User credentials
INI file. (Required)--dns-ionos-propagation-secondswaiting time for DNS to propagate before asking
the ACME server to verify the DNS record.
(Default: 10, Recommended: >= 600)CredentialsAn examplecredentials.inifile:dns_ionos_prefix=myapikeyprefixdns_ionos_secret=verysecureapikeysecretdns_ionos_endpoint=https://api.hosting.ionos.comThe key can be managed under the following link:https://developer.hosting.ionos.de/?source=IonosControlPanelThe path to this file can be provided interactively or using the--dns-ionos-credentialscommand-line argument. Certbot
records the path to this file for use during renewal, but does not store the
file’s contents.CAUTION:You should protect these API credentials as you would the
password to your ionos account. Users who can read this file can use these
credentials to issue arbitrary API calls on your behalf. Users who can cause
Certbot to run using these credentials can complete adns-01challenge to
acquire new certificates or revoke existing certificates for associated
domains, even if those domains aren’t being managed by this server.Certbot will emit a warning if it detects that the credentials file can be
accessed by other users on your system. The warning reads “Unsafe permissions
on credentials configuration file”, followed by the path to the credentials
file. This warning will be emitted each time Certbot uses the credentials file,
including for renewal, and cannot be silenced except by addressing the issue
(e.g., by using a command likechmod 600to restrict access to the file andchmod 700to restrict access to the folder).ExamplesTo acquire a single certificate for bothexample.comand*.example.com, waiting 900 seconds for DNS propagation:certbotcertonly\--authenticatordns-ionos\--dns-ionos-credentials/etc/letsencrypt/.secrets/domain.tld.ini\--dns-ionos-propagation-seconds900\--serverhttps://acme-v02.api.letsencrypt.org/directory\--agree-tos\--rsa-key-size4096\-d'example.com'\-d'*.example.com'DockerIn order to create a docker container with a certbot-dns-ionos installation,
create an empty directory with the followingDockerfile:FROMcertbot/certbotRUNpipinstallcertbot-dns-ionosProceed to build the image:docker build -t certbot/dns-ionos .Once that’s finished, the application can be run as follows:docker run --rm \
   -v /var/lib/letsencrypt:/var/lib/letsencrypt \
   -v /etc/letsencrypt:/etc/letsencrypt \
   --cap-drop=all \
   certbot/dns-ionos certonly \

   --keep-until-expiring --non-interactive --expand \
   --server https://acme-v02.api.letsencrypt.org/directory \
   -d example.com -d '*.example.com'It is suggested to secure the folder as follows::
chown root:root /etc/letsencrypt/.secrets
chmod 700 /etc/letsencrypt/.secretsThe file ‘domain.tld.ini’ must be replaced with the version of the example ‘credentials.ini’ adapted to your provider.Changelog2024.01.08Update README.rst
- Add Link to IONOS control panel and reference between credentials.ini and domain.tld.ini2023.11.13Fix managed zone lookup to ensure correct domain is selected where there are two domains with the same ending e.g. example.com and thisisanexample.com (PR #22)2022.11.24remove zope to fix compatibility with Certbot 2.x (Fixes #19)As a reminder, Certbot will default to issuing ECDSA certificates from release 2.0.0.
If you update from a prior certbot release, run the plugin once manually. You will be prompted
to update RSA key type to ECDSA.2022.05.15
- Added capability to handle multiple domain validations #162021.09.20.post1Fix version number2021.09.20Fix #9 Domain not known when using subdomain
