webhook
|
|
=======
|
|
|
|
|
|
|
|
[webhook][1] 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.
|
|
|
|
## Build Binary
|
|
|
|
To build a docker image from scratch, we need to build static linked binary.
|
|
|
|
```bash
|
|
$ go get -d github.com/adnanh/webhook
|
|
$ CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -installsuffix cgo -ldflags '-s -extld ld -extldflags -static' -a -x -o webhook github.com/adnanh/webhook
|
|
$ file webhook
|
|
```
|
|
|
|
