[Webgrabplus](http://www.webgrabplus.com) is a multi-site incremental xmltv epg grabber. It collects tv-program guide data from selected tvguide sites for your favourite channels.
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
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.
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.**
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.
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](https://en.wikipedia.org/wiki/Umask) before asking for support.
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`.

We publish various [Docker Mods](https://github.com/linuxserver/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.
docker inspect -f '{{ index .Config.Labels "build_version" }}' webgrabplus

* Image version number:
```bash
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/webgrabplus:latest
```
## 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 (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
* 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:
```bash
docker image prune
```
### Via Watchtower auto-updater (only use if you don't remember the original parameters)
* Pull the latest image at its tag and replace it with the same env variables in one run:
```bash
docker run --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once webgrabplus
```
* You can also remove the old dangling images: `docker image prune`
!!! warning
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](https://docs.linuxserver.io/general/docker-compose).
We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
