HTTP Check

HTTP Check is a simple tool that exposes any system command with a single HTTP endpoint. HTTP response code differs depending command status code.

Configuration

Here is an sample configuration file :

---

checks:
  - name: "ping-10.1.1.2"
    command:
      executable: "/sbin/ping %s %d %s"
      args: ["-c", 2, "10.100.0.1"]
    status:
      failure: 223
      success: 200
  - name: "ping-google"
    command:
      executable: "/sbin/ping %s %d %s"
      args: ["-c", 2, "8.8.8.8"]
    status:
      failure: 503
      success: 204

server:
  port: 2323

Installation

1. Download http-check binary from github release
2. Create configuration file. Default location is /etc/http-check/http-check.yml. You can specificy custom location on the command line when running the server

Run the server

Basically run the binary

$ http-check server

Or, with a custom configuration file location

$ http-check server --config /etc/http-check.yml

Clients use a single endpoint to run any check.
