healthchex

Kubernetes Liveness and Readiness Probes as Elixir Plugs.

Installation

The package can be installed by adding healthchex to your list of dependencies in mix.exs:

def deps do
  [
    {:healthchex, "~> x.x.x"}
  ]
end

Usage

To keep the documentation up to date, I decided to not duplicate it here, but include all usage examples as test cases.

Have a look at test/probes directory to see how you can use these Plugs.

defmodule MyApp.Router do
  use Phoenix.Router

  forward "/alive", Healthchex.Probes.Liveness
  forward(
    "/ready",
    Healthchex.Probes.Readiness,
    probe: &Domain.db_ready?/0
  )

  pipeline :api do
    plug :accepts, ["json"]
  end

  scope "/api", MyApp do
    pipe_through :api
  end
end
