HashiCorp Boundary is a tool that provides identity-based remote access and credential management for Kubernetes clusters. It allows administrators to centrally control and precisely assign resources to each remote user using role-based access controls (RBACs). Boundary integrates with HashiCorp Vault to dynamically generate short-lived credentials just-in-time, eliminating the need to store permanent tokens on local laptops or desktops. The process involves configuring a Vault instance, creating a Kubernetes service account token, setting up a credential store in Boundary, and creating hosts and roles for remote users to access their assigned resources. By using Boundary, organizations can centralize remote access and credential management, reducing administrative burden and improving security.
