Webgrabplus is a multi-site incremental xmltv epg grabber. It collects tv-program guide data from selected tvguide sites for your favourite channels.

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/webgrabplus 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=webgrabplus \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -v <path to config>:/config \
  -v <path to data>:/data \
  --restart unless-stopped \
  linuxserver/webgrabplus

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  webgrabplus:
    image: linuxserver/webgrabplus
    container_name: webgrabplus
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - <path to config>:/config
      - <path to data>:/data
    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

Environment Variables (-e)

Env Function
PUID=1000 for UserID - see below for explanation
PGID=1000 for GroupID - see below for explanation
TZ=Europe/London Specify a timezone to use EG Europe/London

Volume Mappings (-v)

Volume Function
/config Where webgrabplus should store it's config files.
/data Where webgrabplus should store it's data files.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

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

To configure WebGrab+Plus follow the documentation

Note that there are some things in the guide that does not apply to this container. Below you can find the changes.

The configuration files are found where your config volume is mounted. Do not change the filename tag in the configuration file!

The /data volume mapping is where WebGrab+Plus outputs the xml file. To use the xml file in another program, you have to point it to the host path you mapped the /data volume to.

To adjust the scheduled cron job for grabbing, edit the wg3-cron file found in the /config folder. After you have edited the the wg3-cron file, restart the container to apply the new schedule. Do not adjust the command!

Note that due to something in version 3, we had to change the commands for scheduling the grab. If you have a version where there is a wg-cron file in your /config mount, delete it and use wg3-cron instead.

Below is the syntax of the cron file.

 ┌───────────── minute (0 - 59)
 │ ┌───────────── hour (0 - 23)
 │ │ ┌───────────── day of month (1 - 31)
 │ │ │ ┌───────────── month (1 - 12)
 │ │ │ │ ┌───────────── day of week (0 - 6) (Sunday to Saturday;
 │ │ │ │ │                                       7 is also Sunday on some systems)
