Overview of this book

Kubernetes is the leading orchestrator of cloud-native apps. With knowledge of how to work with Kubernetes, you can easily deploy and manage applications on the cloud or in your on-premises data center. The book begins by introducing you to Kubernetes and showing you how to install it. You’ll learn how to use Kubernetes Services and bring stable and reliable networking to apps that are deployed on Kubernetes. You'll delve deep into the powerful storage subsystem of Kubernetes and learn how to leverage the variety of external storage backends in your applications. As the book progresses, it shows you how to use features such as DaemonSets, Helm, and RBAC to enhance your Kubernetes applications. You'll explore the six categories of identifying vulnerabilities and look at a few ways to prevent and mitigate them. You'll also look at ways to secure the software delivery pipeline by discussing some image-related best practices. The book ends by sharing with you some resources that’ll help take your Kubernetes knowledge to the next level. By the end of the book, you’ll have the confidence and skills to leverage all the features of Kubernetes to develop scalable applications.

Identity and Access Management (IAM)

Controlling user access to Kubernetes is important in any production environment. Fortunately, Kubernetes has a robust RBAC subsystem that integrates with existing IAM providers such as Active Directory and other LDAP systems.

Most organizations already have a centralized IAM provider, such as Active Directory, that is integrated with company HR systems to simplify employee life cycle management.

Fortunately, Kubernetes leverages existing IAM providers instead of implementing its own. For example, a new employee joining the company will automatically get an identity in Active Directory, which integrates with Kubernetes RBAC to automatically grant that user certain access to Kubernetes. Likewise, an employee leaving the company will automatically have his or her Active Directory identity removed or disabled, resulting in their access to Kubernetes being revoked.

RBAC went GA in Kubernetes 1.8, and it is highly recommended that you leverage...
