This is a back end function for Hiera 5 that allows lookup to be sourced from Hashicorp's Vault.
Vault secures, stores, and tightly controls access to tokens, passwords, certificates, API keys, and other secrets in modern computing. Vault handles leasing, key revocation, key rolling, and auditing. Vault presents a unified API to access multiple backends: HSMs, AWS IAM, SQL databases, raw key/value, and more.
- This moduel is only compatible with Hiera 5 (ships with Puppet 4.9+)
The vault gem must be installed and loadable from Puppet
# /opt/puppetlabs/puppet/bin/gem install vault
# puppetserver gem install vault
The data provider is available by installing the davealden/hiera_vault module into your environment.
# puppet module install davealden/hiera_vault
See The official Puppet documentation for more details on configuring Hiera 5.
