[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.
## 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](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 `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 | arm32v6-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=1001 \
-e PGID=1001 \
-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.
```yaml
---
version: "2"
services:
webgrabplus:
image: linuxserver/webgrabplus
container_name: webgrabplus
environment:
- PUID=1001
- PGID=1001
- TZ=Europe/London
volumes:
- <path to config>:/config
- <path to data>:/data
mem_limit: 4096m
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=1001` | for UserID - see below for explanation |
| `PGID=1001` | 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. |
## 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=1001` and `PGID=1001`, to find yours use `id user` as below:
```
$ id username
uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)
```
## Application Setup
To configure WebGrab+Plus follow the [guide][guideurl]
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)
│ │ │ │ │
│ │ │ │ │
* * * * * s6-setuidgid abc /bin/bash /defaults/update.sh
```
