This project exposes a web server that accepts a Slack webhook post and returns 200 OK.

Hosted instance

curl -s https://mockslackwebhook.octopusdemos.com/   -d '{"whatever": "hello world"}'

Run locally

go test ./...
go run .

Docker image

Build and run the container locally:

docker build -t mock-slack-webhook:local .
docker run --rm -p 8080:8080 mock-slack-webhook:local

GitHub Actions publish to GHCR

The workflow in .github/workflows/docker-publish.yml builds the image on pull requests and builds + pushes on:

• pushes to main
• version tags matching v*
• manual runs (workflow_dispatch)

Image location:

• ghcr.io/<owner>/<repo> (automatically lowercased in the workflow)

Required repository settings:

1. Ensure GitHub Actions has read/write package permissions (repo Settings -> Actions -> General -> Workflow permissions -> Read and write permissions).
2. Ensure package visibility/permissions in GHCR are set as desired after the first publish.
