コードを書くことに集中したい全てのアプリ開発者に贈るKubernetesの話 / Kubernetes Tips for all application engineers who want to focus on coding

コンテナネイティブな時代、アプリケーションエンジニアに求められる技術領域はさらに広がりを見せつつあります。インフラとアプリの境界を変えたコンテナ技術にどこまで踏み込めばいいのか迷っているアプリケーションエンジニアは多いと思います。このセッションでは、アプリケーションエンジニアがコーディングに集中するために知っておきたいコンテナ技術のおさらいから、Kubernetesとその周辺ツールの基本をデモも交えて説明します。(Japan Container Days v18.12)
