Goクライアント

client-go Goライブラリは以下を提供します:

[完全に機能する例]((https://github.com/falcosecurity/client-go/blob/master/examples/output/main.go)を参照して、GoクライアントがFalco gRPC出力APIに接続する方法と、イベントをJSONで表示します。

  1. 例のパスの/tmp/{client.crt,client.key,ca.crt}に証明書があることを確認します。

  2. client-goルートディレクトリから、次のコマンドを実行します:

    $ go run examples/output/main.go | jq
    

    Falcoインスタンスが持っている一連のルールに応じて、出力イベントが流れ始めます。
