Docker PullsDocker StarsBuild Status

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


docker create \
  --name=webgrabplus \
  -v <path to config>:/config \
  -v <path to data>:/data \
  -e PGID=<gid> -e PUID=<uid>  \


The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side. For example with a port -p external:internal - what this shows is the port mapping from internal to external of the container. So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 http://192.168.x.x:8080 would show you what's running INSIDE the container on port 80.

  • -v /config - where webgrabplus should store it's config files
  • -v /data - where webgrabplus should store it's data files
  • -e PGID for GroupID - see below for explanation
  • -e PUID for UserID - see below for explanation

It is based on ubuntu xenial with s6 overlay, for shell access whilst the container is running do docker exec -it webgrabplus /bin/bash.

User / Group Identifiers

Sometimes when using data 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 the data volume directory on the host is owned by the same user you specify and it will "just work" ™.

In this instance PUID=1001 and PGID=1001. To find yours use id user as below:

  $ id <dockeruser>
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)

Setting up the application

To configure WebGrab+Plus follow the guide

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)
