This is a common question, a good solution is the "cubbyhole" technique. https://www.hashicorp.com/blog/vault-cubbyhole-principles.html https://www.hashicorp.com/blog/vault-cubbyhole-principles.ht... I prefer the "pull" model, it can be done with a few lines of code in the CD process: First from the deployer to authorize a new instance, and second on the app/instance to request the token.

I have read the cubbyhole doc and I understand there are two authentication mechanisms as the doc mentions - machine and user oriented. Can you explain how this helps integrate with config management such as Chef and Puppet etc as the OP above was asking. For some reason I'm just not getting it reading the Hashicorp Doc. Thanks.

  Have the temp token generated as part of the deployment process. This temp token can be shown in plaintext to the developer/CD machine/Chef/logs because it is use- and time- limited. If anything besides the new app uses the temp token, the deployment will fail and the token usage can be easily traced to the offender. Regarding machine- or user- oriented, it just depends on whether you trust the deployer (user) or the deployment machine to authorize a new temp token.

    I see, that makes sense. Thanks for the good explanation.

    I'll look into this more. I'm a simple guy so hopefully my initial forays produce fruit easily. Maybe I'll luck out and there will be a blog post from someone on how to implement this specifically with AWS and Chef.

      There's an AWS based auth method based on iam roles and ami ids. Takes a few minutes to set up. https://www.vaultproject.io/docs/auth/aws-ec2.html https://www.vaultproject.io/docs/auth/aws-ec2.html

    A client of mine has a number of windows machines, and a well-organized Active Directory setup. The small group of users who need to be able to create deployment tokens are all in an AD group, and it was pretty straightforward to use the LDAP auth backend with vault to allow them to create those one-time use tokens using their normal network logins. Everyone's super impressed so far.
