Provisioning Vault with Code

A couple of years ago, Hashicorp published a blog post “Codifying Vault Policies and Configuration“. We used a heavily modified version of their scripts to get us going with Vault.

However there are a few problems with the approach, some of which are noted in the original post.

The main one is that if we remove a policy from the configuration, applying it again will not remove the objects from Vault. Essentially it is additive only, and while it will modify existing objects and create new ones, removing objects that are no longer declared is arguably just as important.

Another problem is that shell scripts inevitably have dependencies, which you may not want to install¬†on your shell servers. Curl, in particular, is extremely useful for hackers, and we don’t want to have it available in production (in our environment, access to the vault API from outside the network is not allowed).

Finally, shell scripts aren’t easy to test, and don’t scale particularly well as complexity grows. You can do some amazing things in bash, but once it gets beyond a few hundred lines it’s time to break out into a proper language.

So that’s what I did.

The result is a tool called vaultsmith, and it’s designed to do one thing – take a directory of json files and apply them to your vault server.
