linuxserver/davos

Davos is an FTP automation tool that periodically scans given host locations for new files. It can be configured for various purposes, including listening for specific files to appear in the host location, ready for it to download and then move, if required. It also supports completion notifications as well as downstream API calls, to further the workflow.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling linuxserver/davos should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Usage

Here are some example snippets to help you get started creating a container from this image.

docker

docker create \
  --name=davos \
  -e PUID=1000 \
  -e PGID=1000 \
  -p 8080:8080 \
  -v <path to data>:/config \
  -v <path to downloads folder>:/download \
  --restart unless-stopped \
  linuxserver/davos

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2"
services:
  davos:
    image: linuxserver/davos
    container_name: davos
    environment:
      - PUID=1000
      - PGID=1000
    volumes:
      - <path to data>:/config
      - <path to downloads folder>:/download
    ports:
      - 8080:8080
    restart: unless-stopped

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Parameter	Function
8080	This is the default port that davos runs under

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation

Volume Mappings (-v)

Volume	Function
/config	davos's config location. This is where it stores its database file and logs.
/download	davos's file download location

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Application Setup

The application does not require any set up other than starting the docker container. Further documentation can be found on the davos GitHub repository page.

Support Info

• Shell access whilst the container is running:
  • docker exec -it davos /bin/bash
• To monitor the logs of the container in realtime:
  • docker logs -f davos
• Container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' davos
• Image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/davos
