Getting Started

This is a Vault plugin and is meant to work with Vault. This guide assumes you have already installed Vault and have a basic understanding of how Vault works.

Otherwise, first read this guide on how to get started with Vault.

Developing

If you wish to work on this plugin, you'll first need Go installed on your machine.

If you're developing for the first time, run make bootstrap to install the necessary tools. Bootstrap will also update repository name references if that has not been performed ever before.

$ make bootstrap

To compile a development version of this plugin, run make or make dev. This will put the plugin binary in the bin and $GOPATH/bin folders. dev mode will only generate the binary for your platform and is faster:

$ make dev

Put the plugin binary into a location of your choice. This directory will be specified as the plugin_directory in the Vault config used to start the server.

# config.hcl
plugin_directory = "path/to/plugin/directory"
...

Start a Vault server with this config file:

$ vault server -dev -config=path/to/config.hcl ...
...

Once the server is started, register the plugin in the Vault server's plugin catalog:

$ SHA256=$(openssl dgst -sha256 $GOPATH/vault-plugin-secrets-myplugin | cut -d ' ' -f2)
$ vault plugin register \
        -sha256=$SHA256 \
        -command="vault-plugin-secrets-myplugin" \
        secrets myplugin
...
Success! Data written to: sys/plugins/catalog/myplugin

Enable the secrets engine to use this plugin:

$ vault secrets enable myplugin
...

Successfully enabled 'plugin' at 'myplugin'!

Tests

To run the tests, invoke make test:

$ make test

You can also specify a TESTARGS variable to filter tests like so:

$ make test TESTARGS='-run=TestConfig'
