webhook is a lightweight configurable tool written in Go, that allows you to easily create HTTP endpoints (hooks) on your server, which you can use to execute configured commands. You can also pass data from the HTTP request (such as headers, payload or query variables) to your commands. webhook also allows you to specify rules which have to be satisfied in order for the hook to be triggered.
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 ghcr.io/linuxserver-labs/webhook 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 | latest |
| arm64 | arm64v8-latest |
| armhf | arm32v7-latest |
This image looks at the json file /config/hooks/hooks.json for configuring webhooks. Configuration instructions can be found upstream.
Here are some example snippets to help you get started creating a container.
docker-compose (recommended, click here for more info)
---
version: "2.1"
services:
webhook:
image: ghcr.io/linuxserver-labs/webhook
container_name: webhook
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/Oslo
- EXTRA_PARAM= #optional
volumes:
- /path/to/config:/config
ports:
- 9000:9000
restart: unless-stoppeddocker cli (click here for more info)
docker run -d \
--name=webhook \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/Oslo \
-e EXTRA_PARAM= `#optional` \
-p 9000:9000 \
-v /path/to/config:/config \
--restart unless-stopped \
ghcr.io/linuxserver-labs/webhookContainer 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 |
|---|---|
-p 9000 |
Endpoint for receival of webhooks |
-e PUID=1000 |
for UserID - see below for explanation |
-e PGID=1000 |
for GroupID - see below for explanation |
-e TZ=Europe/Oslo |
Specify a timezone to use e.g. Europe/London. |
-e EXTRA_PARAM= |
Additional CLI arguments to pass to the application. |
-v /config |
Stores config and application files |
You can set any environment variable from a file by using a special prepend FILE__.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpasswordWill set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.
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.
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)
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.
- Shell access whilst the container is running:
docker exec -it webhook /bin/bash - To webhookor the logs of the container in realtime:
docker logs -f webhook - container version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' webhook
- image version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver-labs/webhook
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 all images:
docker-compose pull- or update a single image:
docker-compose pull webhook
- 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 webhook
- or update a single container:
- You can also remove the old dangling images:
docker image prune
- Update the image:
docker pull ghcr.io/linuxserver-labs/webhook - Stop the running container:
docker stop webhook - Delete the container:
docker rm webhook - Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your
/configfolder and settings will be preserved) - 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 webhook
-
You can also remove the old dangling images:
docker image prune
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.
- We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
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-labs/docker-webhook.git
cd docker-webhook
docker build \
--no-cache \
--pull \
-t ghcr.io/linuxserver-labs/webhook: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 --resetOnce registered you can define the dockerfile to use with -f Dockerfile.aarch64.
- 21.09.23: - Rebase to alpine 3.18, deprecate arm32v7 (armhf) per this notice.
- 14.01.22: - Initial release.
