Overview

-
-
-

This Quick Start deploys HashiCorp Vault on the AWS Cloud. This guide covers the steps necessary to deploy this Quick Start.

-
-
-

HashiCorp Vault is a product that centrally secures, stores, and tightly controls access to tokens, passwords, certificates, encryption keys, protecting secrets and other sensitive data through a user interface (UI), a command line interface (CLI), or an HTTP application programming interface (API). Vault’s core use cases include the following:

-
-
-
    -
  • -

    Secrets management: Securely manage and deploy secrets across different environments, applications, and services.

    -
    • -
  • -

    Encryption and data protection: Manage encryption and keys for developers and operators across different environments, applications, and services.

    -
    • -
  • -

    Privileged-access management: Secure workloads for application-to-application and user-to-application credential management across different environments and services.

    -
    • -
-
-
-

Vault is designed for DevOps professionals and application developers who want to manage their secrets, data, and key-value stores. It’s built using the open-source version of Vault, but it’s also compatible with Vault Enterprise.

-
-
-

Supplemental details, with instructions and screenshots, are available on the HashiCorp Vault and Vault Enterprise websites.

-

This Quick Start provides the following deployment options:

-
-
-
    -
  • -

    Deploy Vault into a new VPC. This option builds a new AWS environment that consists of the VPC, subnets, NAT gateways, security groups, bastion hosts, and other infrastructure components. It then deploys Vault into this new VPC.

    -
    • -
  • -

    Deploy Vault into an existing VPC. This option provisions Vault in your existing AWS infrastructure.

    -
    • -
-
-

Troubleshooting

-
-
-

For troubleshooting common Quick Start issues, refer to the AWS Quick Start General Information Guide and Troubleshooting CloudFormation.

-
-
-

Encountering a CREATE_FAILED error when launching the Quick Start

-
-

If AWS CloudFormation fails to create the stack, relaunch the template with Rollback on failure set to No. This setting is under Advanced in the AWS CloudFormation console on the Options page. With this setting, the stack’s state is retained and the instance is left running, so you can troubleshoot the issue. (For Windows, look at the log files in %ProgramFiles%\Amazon\EC2ConfigService and C:\cfn\log.)

-
-
- - - - - -
- - -When you set Rollback on failure to Disabled, you continue to incur AWS charges for this stack. Be sure to delete the stack when you finish troubleshooting. -
-
-
-

For additional information, see Troubleshooting AWS CloudFormation on the AWS website.

-
-
-
-

Encountering a size limitation error when deploying the AWS CloudFormation templates

-
-

Launch the Quick Start templates from the links in this guide or from another S3 bucket. If you deploy the templates from a local copy on your computer or from a location other than an S3 bucket, you might encounter template size limitations. For more information, refer to AWS CloudFormation quotas.

-
-
-
-

Resources

-
- -
-
-

After you successfully deploy a Quick Start, confirm that your resources and services are updated and configured—including any required patches—to meet your security and other needs. For more information, refer to the Shared Responsibility Model.
