ddclient-snap

ddclient (snap)

ddclient is a Perl client used to update dynamic DNS entries for accounts on many dynamic DNS services.

See supported services in the offical read me of ddlient's repository at github.

Usage

When this snap is installed, there will be a background daemon running (called ddclient-snap.daemon). This daemon reads your configuration from the file /var/snap/ddclient-snap/current/etc/ddclient/ddclient.conf.

Fill in your details and restart the service with snap restart ddclient-snap.daemon. If you're having problems, please see the question asked by a user.

If you want to execute commands manually, you'll have the exectuable available with ddclient-snap.exec.

Build and installation instructions

Install from The Snap Store (Recommended)

Make sure you have Snapd installed on your system. See Installing snapd for a list of distributions with and without snap pre-installed, including installation instructions for those that have not.

$ snap install ddclient-snap

Build this snap from source

We recommend that your download a pre-built version of this snap from The Snap Store, or at least make sure that you checkout the latest tag, as the master tag might contain faulty code during development.

1. Clone this repo and checkout the latest tag

$ git clone https://git.giaever.org/joachimmg/ddclient-snap.git

# Go into directory
$ cd ./ddclient-snap

# Checkout tag
$ git checkout <tag>

NOTE: You can find the latest tag with git ls-remote --tags origin

1. Build and install

Make sure you have snapd (see Installing snapd) and latest version of Snapcraft. Install Snapcraft with

$ sudo snap install snapcraft --classic

Or update with

$ sudo snap refresh snapcraft

2.2 With multipass

From the «ddclient-snap»-directory, run

$ snapcraft

Multipass will be installed and a virtual machine will boot up and build your snap. The final snap will be located in the same directory.

2.3 With LXD (required for Raspberry Pie)

Snapcraft will try to install multiplass and build the snap for you, but on Raspberry Pi it will fail. You will have to use an LXD container.

Install LXD and create a container

$ snap install lxd
$ snap lxd init

Make sure your user is a member of lxd-group

$ sudo adduser $USER lxd

Launch an Ubuntu 20.04 container instance

$ lxc launch ubuntu:20.04 ddclient-snap

Clone repo as described in #1

Make sure you're in the «ddclient-snap»-directory and go into the shell of your newly created container

$ lxc exec -- ddclient-snap /bin/bash

and run

$ SNAPCRAFT_BUILD_ENVIRONMENT=host snapcraft

when the build is complete, you'll have to exit the shell and pull the snap-file from the container. See lxc file pull --help.

1. Install new built snap

   $ sudo snap install ./ddclient-snap_<source-tag>.snap --dangerous
