Which tool can interact securely with HashiCorp Vault?

HashiCorp Vault is designed to manage and secure sensitive data, and various tools can interact with it in a secure manner. Terraform, Git, and Docker each have specific use cases that integrate securely with Vault.

Terraform can securely manage secrets and configuration data by using Vault as a backend for storing sensitive information related to infrastructure provisioning. By leveraging Vault, Terraform can ensure that sensitive data such as API keys or database credentials are not hardcoded in the configuration files.

Git, while primarily a version control system, can be configured to use Vault for managing sensitive information in code repositories. For example, developers might use Vault as a secure storage solution for secrets that are referenced in applications managed with Git, ensuring that sensitive data doesn't get exposed in the repository.

Docker containers can also interact with Vault to securely access the secrets needed for applications running within those containers. For instance, a Docker container can retrieve credentials stored in Vault at runtime, which enhances security by preventing hardcoding of sensitive information in the application code or environment variables.

Since all three of these tools can effectively utilize Vault's capabilities for secure data management while fitting within different parts of a typical DevOps workflow, stating that all of the options can securely interact with HashiCorp Vault is accurate.
