This image containerizes the prebuilt static Webhook server by HookDoo, used to serve incoming webhooks with custom actions/scripts.
Auto updated according to the Github stable releases.
Based on Alpine Linux from my alpine-glibc image with the s6 init system overlayed in it.
The image is tagged respectively for the following architectures,
- armhf
- armv7l
- aarch64
- x86_64 (retagged as the
latest
)
non-x86_64 builds have embedded binfmt_misc support and contain the qemu-user-static binary that allows for running it also inside an x86_64 environment that has it.
Pull the image for your architecture it's already available from Docker Hub.
# make pull
docker pull woahbase/alpine-webhook:x86_64
If you want to run images for other architectures, you will need to have binfmt support configured for your machine. multiarch, has made it easy for us containing that into a docker container.
# make regbinfmt
docker run --rm --privileged multiarch/qemu-user-static:register --reset
Without the above, you can still run the image that is made for your architecture, e.g for an x86_64 machine..
This image already has a user alpine
configured to drop
privileges to the passed PUID
/PGID
which is ideal if its used
to run in non-root mode. That way you only need to specify the
values at runtime and pass the -u alpine
if need be. (run id
in your terminal to see your own PUID
/PGID
values.)
Before you run..
-
Default hooks dir is
/etc/webhook/
. -
config is loaded from
/etc/webhook/hooks.json
, a simple default is provided, edit this file or mount your own. The location of the the file can be customized by setting the variableHOOKSJSON
. -
To fetch the hooks.json file from a url before start, pass it in the env variable
HOOKSURL
. -
For custom runtime parametes, pass them in the environment variable
HOOKPARAMS
. (check the defaults in themakefile
) -
Checkout the docs for more information about writing hooks.
-
Webhook runs under the user
alpine
.
Running make
starts the service.
# make
docker run --rm -it \
--name docker_webhook --hostname webhook \
-e PGID=1000 -e PUID=1000 \
-p 9000:9000 \
-e HOOKPARAMS="-verbose -ip 0.0.0.0" \
-v config/hooks.json:/etc/webhook/hooks.json \
woahbase/alpine-webhook:x86_64
Stop the container with a timeout, (defaults to 2 seconds)
# make stop
docker stop -t 2 docker_webhook
Removes the container, (always better to stop it first and -f
only when needed most)
# make rm
docker rm -f docker_webhook
Restart the container with
# make restart
docker restart docker_webhook
Get a shell inside a already running container,
# make debug
docker exec -it docker_webhook /bin/bash
set user or login as root,
# make rdebug
docker exec -u root -it docker_webhook /bin/bash
To check logs of a running container in real time
# make logs
docker logs -f docker_webhook
If you have the repository access, you can clone and build the image yourself for your own system, and can push after.
Before you clone the repo, you must have Git, GNU make, and Docker setup on the machine.
git clone https://github.com/woahbase/alpine-webhook
cd alpine-webhook
You can always skip installing make but you will have to type the whole docker commands then instead of using the sweet make targets.
You need to have binfmt_misc configured in your system to be able to build images for other architectures.
Otherwise to locally build the image for your system.
[ARCH
defaults to x86_64
, need to be explicit when building
for other architectures.]
# make ARCH=x86_64 build
# sets up binfmt if not x86_64
docker build --rm --compress --force-rm \
--no-cache=true --pull \
-f ./Dockerfile_x86_64 \
--build-arg DOCKERSRC=woahbase/alpine-glibc:x86_64 \
--build-arg PGID=1000 \
--build-arg PUID=1000 \
-t woahbase/alpine-webhook:x86_64 \
.
To check if its working..
# make ARCH=x86_64 test
docker run --rm -it \
--name docker_webhook --hostname webhook \
-e PGID=1000 -e PUID=1000 \
woahbase/alpine-webhook:x86_64 \
sh -ec 'sleep 5; webhook -version'
And finally, if you have push access,
# make ARCH=x86_64 push
docker push woahbase/alpine-webhook:x86_64
