erichough/duplicacy repository overview

⁠erichough/duplicacy

Duplicacy Web Edition⁠ in a container.

⁠Quick Start

1. docker run -p 3875:3875 erichough/duplicacy

2. Visit http://localhost:3875⁠

⁠Production Usage

1. Bind-mount a host directory into the container at /etc/duplicacy to view, edit, and/or backup your configuration files (i.e. duplicacy.json and settings.json).
2. Bind-mount a host directory into the container at /var/cache/duplicacy to retain statistics and cached data between container starts, stops, and restarts.
3. Set your container's timezone using one of the following techniques:

   1. Set the TZ environment variable to your desired timezone name⁠.

      docker run -e TZ=America/LosAngeles ... erichough/duplicacy

   2. Bind-mount /etc/localtime and /etc/timezone into the container. e.g.

      docker run                             \
        -v /etc/localtime:/etc/localtime:ro  \
        -v /etc/timezone:/etc/timezone:ro    \
        ...                                  \
        erichough/duplicacy
      

      Copy
4. Add --cap-drop=ALL for extra security.
5. Add --restart=always to be able to make changes via the settings page.

⁠Duplicacy license

NOTE: If you don't need to purchase a Duplicacy license, you can safely ignore this section.

Duplicacy identifies the machine via the hostname and machine-id⁠ pair. So in order to utilize a license, you'll need to make sure that both of these pieces of data do not change over time.

1. Add --hostname to your to your docker run command to set a persistent hostname for the container.

2. Supply a persistent machine-id, which is a 32-character lowercase hexadecimal string.

   Here are a few ways to supply a machine-id; choose whichever your like:

   1. Option 1. Bind-mount an existing machine-id into the container at /var/lib/dbus/machine-id.

      e. g. docker run -v /host/path/to/machine-id:/var/lib/dbus-machine-id:ro ...

   2. Option 2. Supply the MACHINE_ID environment variable to the container. You can generate a random string using online tools (example⁠).

      e.g. docker run -e MACHINE_ID=b23c9e0140e92b10c2baaf1f82571a2f ...

   3. Option 3. Bake /var/lib/dbus/machine-id into a custom image. e.g. in a Dockerfile

      FROM erichough/docker-duplicacy
      COPY files/machine-id /var/lib/dbus/machine-id
      

      Copy
