Duplicacy-Web wrapper

This is a wrapper around http://duplicacy.com web GUI.

Two branches are supported:

• latest: the classic one with the fixed version of duplicacy_web baked into the image. x86_64 only.
• mini: The container downloads and caches the correct binary of duplicacy_web for the host architecture and selected version on start. To update/downgrade to another version change the environment variable and restart the container. Supports x86_x64 and arm.

Notes:

• Arm detection is untested.
• Download-on-demand approach was already used by duplicacy_web to fetch the updated version of a duplicacy cli engine. The mini container now extends this behavior to duplicacy_web itself making it easy to switch between versions at your cadence.

Volumes

/config -- is where configuration data will be stored. Should be backed up.

/logs -- logs will go there.

/cache -- transient and temporary files will be stored here. Can be safely deleted.

Environment variables

Common variables

USR_ID and GRP_ID: User and group ID under which the duplicacy_web will be running.

TZ: time zone. Refer to https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

USR_ID and GRP_ID can be customized. Container will run as that user. By default user 0 (root) is used.

:mini only

DUPLICACY_WEB_VERSION: Specifies version of duplicacy_web to fetch and use.

To apply the changes restart the container. This makes the :mini version behave more like a thin adapter layer as opposed to true self-encompassing container.

To run

An example for :mini branch; the duplicacy_web version is selectable via environment variable:

docker run  --name duplicacy-web-docker-container         \
        --hostname duplicacy-web-docker-instance          \
         --publish 3875:3875/tcp                          \
             --env USR_ID=$(id -u)                        \
             --env GRP_ID=$(id -g)                        \
             --env TZ="America/Los_Angeles"               \
             --env DUPLICACY_WEB_VERSION="1.4.1"          \
          --volume ~/Library/Duplicacy:/config            \
          --volume ~/Library/Logs/Duplicacy/:/logs        \
          --volume ~/Library/Caches/Duplicacy:/cache      \
          --volume ~:/backuproot:ro                       \
                   saspus/duplicacy-web:mini 

An example for :latest branch; the duplicacy_web version is baked into the container:

docker run  --name duplicacy-web-docker-container         \
        --hostname duplicacy-web-docker-instance          \
         --publish 3875:3875/tcp                          \
             --env USR_ID=$(id -u)                        \
             --env GRP_ID=$(id -g)                        \
             --env TZ="America/Los_Angeles"               \
          --volume ~/Library/Duplicacy:/config            \
          --volume ~/Library/Logs/Duplicacy/:/logs        \
          --volume ~/Library/Caches/Duplicacy:/cache      \
          --volume ~:/backuproot:ro                       \
                   saspus/duplicacy-web:latest 

Note, it's important to pass hostname, as duplicacy license is requested based on hostname and machine-id provided by dbus. Machine-id will be persisted in the /config directory.

To use

Go to http://hostname:3875
