nix build .#container

Push to registry

nix run .#push-container

nix run

Module

The flake also includes a NixOS module for ease of use. A minimal configuration will look like this:


# Add to flake inputs
inputs.alertmanager-ntfy.url = "github:pinpox/alertmanager-ntfy";

# Import the module in your configuration.nix
imports = [
	self.inputs.alertmanager-ntfy.nixosModules.default
];

# Enable and set options
services.alertmanager-ntfy = {
	enable = true;
	httpAddress = "localhost";
	httpPort = "9999";
	ntfyTopic = "https://ntfy.sh/test";
	ntfyPriority = "high";
	envFile = "/var/src/secrets/alertmanager-ntfy/envfile";
};
