OS X上のDockerでKafkaを実行するには？

Question

私は数日前にドッカーなしでカフカを走ろうとしましたが、もう一度失敗しました。セットアップが非常に難しいです。だから、私はDockerを使うことにしました。そして私はもう一度失敗しました。何が問題なの？

---

私は、これらのコマンドを実行しました：

git clone https://github.com/confluentinc/cp-docker-images 
cd cp-docker-images/examples/kafka-single-node 
docker-compose up 

はところで、これは私です：

• ドッカーバージョン：17.03.1-CE
• ドッカーバージョンを構成します： 1.11.2、構築dfed245

新しいDocker for OS X hereをダウンロードしました。

SIDE注：OS X用新ドッカーは、以前のものとは異なるアーキテクチャを使用していますので、ドッカーとOS Xの多くの前の問題を解決します。だから、Confluent Dockerのドキュメントで話されている問題のほとんどは、扱いやすくなります。

ドッカーは最近、モービーに社名を変更し、それは私の問題を引き起こしました。私は私のドッカーの構成設定でローカルホストとしてmobyを追加する必要がありました。ローカルホストは、この問題を解決するようにモービーを解決extra_hostsパラメータ加えることにより
