Action Slack Notify

(Forked from rtCamp/action-slack-notify)

This repo builds a Go binary based on this image and then starts it with a shell script. This avoids unnecessary usage of Docker. It can even be used in the same way as the original. Some things have been ripped out of the shell scripts since we provide those environment variables already and wanted to avoid installing extra dependencies.

How to build

Install UPX (for packing binary)

sudo apt install upx

NOTE: All builds are expected to target Linux.

From POSIX:

env GOOS=linux GOARCH=amd64 go build -ldflags="-s -w" -o bin/slack-notify main.go
sudo upx --brute ./bin/slack-notify

From Windows (PowerShell 7+):

$Env:GOOS = "linux"; $Env:GOARCH = "amd64"; go build -ldflags="-s -w" -o bin/slack-notify main.go
wsl bash -c -i "sudo upx --brute ./bin/slack-notify"

You may need to update permissions for Linux on Windows. You can do this with
git update-index --chmod=+x ./bin/slack-notify
