⁠linuxserver/webgrabplus⁠

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

We utilise the docker manifest for multi-platform awareness. More information is available from docker here⁠ and our announcement here⁠.

Simply pulling lscr.io/linuxserver/webgrabplus:latest 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:

⁠Application Setup

To configure WebGrab+Plus follow the documentation⁠

Please note that depending on your host this container may not work with the no-new-privileges=true security-opt.

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, you can apply our universal cron mod⁠.

⁠Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

⁠docker-compose (recommended, click here for more info⁠)

services:
  webgrabplus:
    image: lscr.io/linuxserver/webgrabplus:latest
    container_name: webgrabplus
    hostname: webgrabplus
    mac_address: 00:00:00:00:00:00
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /path/to/webgrabplus/config:/config
      - /path/to/data:/data
    restart: unless-stopped

⁠docker cli (click here for more info⁠)

docker run -d \
  --name=webgrabplus \
  --hostname=webgrabplus \
  --mac-address=00:00:00:00:00:00 \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -v /path/to/webgrabplus/config:/config \
  -v /path/to/data:/data \
  --restart unless-stopped \
  lscr.io/linuxserver/webgrabplus:latest

⁠Parameters

Containers 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.

⁠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__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable 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 your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

⁠Docker Mods

We publish various Docker Mods⁠ to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

⁠Support Info

• Shell access whilst the container is running:

  docker exec -it webgrabplus /bin/bash
  

  Copy

• To monitor the logs of the container in realtime:

  docker logs -f webgrabplus
  

  Copy

• Container version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' webgrabplus
  

  Copy

• Image version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/webgrabplus:latest
  

  Copy

⁠Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup⁠ section above to see if it is recommended for the image.

Below are the instructions for updating containers:

⁠Via Docker Compose

• Update images:

  • All images:

    docker-compose pull
    

    Copy

  • Single image:

    docker-compose pull webgrabplus
    

    Copy

• Update containers:

  • All containers:

    docker-compose up -d
    

    Copy

  • Single container:

    docker-compose up -d webgrabplus
    

    Copy

• You can also remove the old dangling images:

  docker image prune
  

  Copy

⁠Via Docker Run

• Update the image:

  docker pull lscr.io/linuxserver/webgrabplus:latest
  

  Copy

• Stop the running container:

  docker stop webgrabplus
  

  Copy

• Delete the container:

  docker rm webgrabplus
  

  Copy

• Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)

• You can also remove the old dangling images:

  docker image prune
  

  Copy

⁠Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-webgrabplus.git
cd docker-webgrabplus
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/webgrabplus:latest .

The ARM variants can be built on x86_64 hardware and vice versa using lscr.io/linuxserver/qemu-static

docker run --rm --privileged lscr.io/linuxserver/qemu-static --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
