Rancher Virtual Rodeo Japan 2020/04「初回編」オンラインワークショップ

Rancher Virtual Rodeosは、DevOpsおよびITチームがKubernetesをどこにでもデプロイして管理するために、必要かつ実践的なスキルを提供するように設計された無料のオンラインワークショップです。コンテナおよびKubernetesの使用方法について興味がある方に向けたこのワークショップはRancherのテクニカルエキスパートによって実施されます。テクニカルエキスパートがRancher、Docker、Kubernetesをご紹介、Kubernetesクラスタをデプロイするための手順をご説明します。

今回初めてRancher Virtual Rodeo Japanを実施します。「初回編」としてRodeoのご紹介を目的とし、ハンズオンも簡易的に行います。今後は実践編なども企画しますので、このワークショップへのご理解を深めていただく内容とします。

Rancher Virtual Rodeoが実施する主要なトピックには次のものが含まれます。
- DockerおよびKubernetesの概念とアーキテクチャ
- Rancherサーバのインストールと設定
- Kubernetesクラスタのデプロイ
- アプリケーションのデプロイ

参加者準備
- GoToWebinarのインストール。登録後Webinar URLよりインストールできます。
- 最新アップデート済みのブラウザ（Chrome、FF、Edge、IE8+）を搭載したPC。
- ワークショップはHobbyFarmというインタラクティブなWebベースのツールを使用して行われます。このツールを使用すると学習シナリオに従いながら、ブラウザ内ターミナルを介してコンピューティングリソースにアクセスできます。

お申込み情報は https://www.rancher.co.jp/ およびConnpassグループ https://rancher.connpass.com/ にてご案内を予定しております。
