Webgrabplus is a multi-site incremental xmltv epg grabber. It collects tv-program guide data from selected tvguide sites for your favourite channels.
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 |
Here are some example snippets to help you get started creating a container.
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
Compatible with docker-compose v2 schemas.

version: "2"
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
Container 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.
| Parameter | Function |
|---|---|
-e PUID=1000 |
for UserID - see below for explanation |
-e PGID=1000 |
for GroupID - see below for explanation |
-e TZ=Europe/London |
Specify a timezone to use EG Europe/London |
-v /config |
Where webgrabplus should store it's config files. |
-v /data |
Where webgrabplus should store it's data files. |
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.
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)
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 wg-cron file found in the /config folder. After you have edited the the wg-cron file, restart the container to apply the new schedule.
Do not adjust the command!
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)
│ │ │ │ │

- Shell access whilst the container is running:
docker exec -it webgrabplus /bin/bash - To monitor the logs of the container in realtime:
docker logs -f webgrabplus - container version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' webgrabplus
- image version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/webgrabplus
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), 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:
- Update the image:
docker pull linuxserver/webgrabplus - Stop the running container:
docker stop webgrabplus - Delete the container:
docker rm webgrabplus - Recreate a new container with the same docker create parameters as instructed above (if mapped correctly to a host folder, your
/configfolder and settings will be preserved) - Start the new container:
docker start webgrabplus - You can also remove the old dangling images:
docker image prune
- Update all images:
docker-compose pull- or update a single image:
docker-compose pull webgrabplus
- or update a single image:
- Let compose update all containers as necessary:
docker-compose up -d- or update a single container:
docker-compose up -d webgrabplus
- or update a single container:
- You can also remove the old dangling images:
docker image prune
- Pull the latest image at its tag and replace it with the same env variables in one run:
docker run --rm \ -v /var/run/docker.sock:/var/run/docker.sock \ containrrr/watchtower \ --run-once webgrabplus
Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.
- You can also remove the old dangling images:
docker image prune
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 linuxserver/webgrabplus:latest .
The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static
docker run --rm --privileged multiarch/qemu-user-static:register --reset
Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
