Contact Vault with Self-signed CA

[valentin2105]

Hello,

First of all, thanks for the module.

I'm trying to make this module work with a Vault Cluster exposing port 8200 with a Self-signed CA .

For the Deferred mode, It work after modifying the puppet.conf of the agent , by adding localcacert pointing to my CA, in the main section.

But for the "Puppet server mode" (without Deferred), (which I need because the configuration file that I want to deploy is a ERB template and the Deferred seem not work in this mode because its created on the server side.)

It give us Java errors :

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I tried adding the CA and even the vault node certificate in the Java Keystore, but it seem ignored. (after server restart)

Any feedback on this ?

I read that we need to use puppet'CA, but in my case, we have a specific CA different from the puppet one, and have to use it.

You don't want to evaluate the EPP server side, as that exposes the secrets to the compile server. Do something like:

content => Deferred('inline_epp', [file($my_epp_path), $parameters])

We also have a ruby function to find the template file based on Puppet::Parser::Files.find_template(file, scope.compiler.environment) to make the above more ergonomic.

All of this really should be easier.

I succeeded connect my Puppet to Vault by using the Puppet certificates to Vault TLS.
And I avoid Deferred because our Puppet recipes are writted in only ERB template. (and too much work to move to EPP).

I would be nice to be able to add the Vault CA on the PuppetServer keystore ?

Nobody have achieved that ?

Hello,
I have the same issue.
In my specific use case I am forced to use the module without Deferred because I have a binary secret base64 encoded in Vault so I need to apply to it the Binary function before to use it (It is the content of a binary file). Using Deferred I got a compile error because I cannot apply Binary() to a deferred type.
Any suggestion? I cannot use puppet certificate in my Vault instance
