A Complete Guide to Docker for Operations and Development: Test-Prep for the Docker Certified Associate (DCA) Exam (Paperback)

Harness the power of Docker by containerizing your code with all its libraries and file systems to consistently run anywhere. This book is your source for learning all about Docker operations and development. It’s divided into two units and focuses on the topics that the Docker Certified Associate exam covers.

Unit 1 covers the Docker fundamentals, such as Docker Enterprise for Operations, Docker Enterprise for Developers, Swarm, and an introduction to Kubernetes. You will learn how to install Docker Community Edition, Docker Enterprise Edition with Kubernetes and CLI. Also, you will learn the Docker cycle, container lifecycle, develop applications in any language, wrap, build, ship, and deploy them for production. Finally, you will learn how to create a Swarm cluster, deploy an app to it, and manage it with the best practices according to the current technologies.

Unit 2 provides quizzes to help you prepare for the certification test. The DCA exam format and the question style has changed since Mirantis acquired Docker. To accommodate this, the quizzes mirror these changes.  

What You’ll Learn

- Understand the difference between containerization and virtualization
- Install Docker CE on various platforms and manage the resources
- Write Dockerfile, Docker Compose YAML, and Kubernetes manifest YAML files
- Compare microservices and monolithic applications
- Containerize monolithic applications

Who This Book Is For

 Software developers, Cloud Architects, and DevOps operation managers.

利用 Docker 的威力，將您的程式碼連同所有的函式庫和檔案系統容器化，以便在任何地方一致運行。本書是您學習 Docker 操作和開發的來源。它分為兩個單元，並專注於 Docker Certified Associate 考試涵蓋的主題。

第一單元涵蓋 Docker 的基礎知識，例如 Docker Enterprise for Operations、Docker Enterprise for Developers、Swarm 和 Kubernetes 的介紹。您將學習如何安裝 Docker Community Edition、帶有 Kubernetes 和 CLI 的 Docker Enterprise Edition。此外，您還將學習 Docker 的週期、容器的生命週期、以任何語言開發應用程式、封裝、建置、部署以及將其用於生產。最後，您將學習如何建立一個 Swarm 叢集，將應用程式部署到其中，並根據當前技術的最佳實踐來管理它。

第二單元提供測驗，以幫助您準備認證考試。自從 Mirantis 收購 Docker 以來，DCA 考試的格式和問題風格已經改變。為了適應這一點，測驗反映了這些變化。

您將學到什麼：

- 理解容器化和虛擬化的差異
- 在各種平台上安裝 Docker CE 並管理資源
- 撰寫 Dockerfile、Docker Compose YAML 和 Kubernetes manifest YAML 檔案
- 比較微服務和巨集應用程式
- 將巨集應用程式容器化

適合閱讀對象：

軟體開發人員、雲架構師和 DevOps 運營經理。
