Quick Links
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.
To learn specifically about how plugins work, see documentation on Vault plugins.
Usage
Please see documentation for the plugin on the Vault website.
This plugin is currently built into Vault and by default is accessed
at azure
. To enable this in a running Vault server:
$ vault secrets enable azure
Success! Enabled the azure secrets engine at: azure/
Developing
If you wish to work on this plugin, you'll first need Go installed on your machine (version 1.17+ is required).
For local dev first make sure Go is properly installed, including
setting up a GOPATH.
Next, clone this repository into
$GOPATH/src/github.com/hashicorp/vault-plugin-secrets-azure
.
You can then download any required build tools by bootstrapping your
environment:
$ 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
$ 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.
...
plugin_directory = "path/to/plugin/directory"
...
Start a Vault server with this config file:
$ vault server -config=path/to/config.json ...
...
Once the server is started, register the plugin in the Vault server's plugin catalog:
$ vault write sys/plugins/catalog/azure \
sha256=<expected SHA256 Hex value of the plugin binary> \
command="vault-plugin-secrets-azure"
...
Success! Data written to: sys/plugins/catalog/azure
Note you should generate a new sha256 checksum if you have made changes to the plugin. Example using openssl:
openssl dgst -sha256 $GOPATH/vault-plugin-secrets-azure
...
SHA256(.../go/bin/vault-plugin-secrets-azure)= 896c13c0f5305daed381952a128322e02bc28a57d0c862a78cbc2ea66e8c6fa1
Enable the auth plugin backend using the secrets enable plugin command:
$ vault secrets enable -plugin-name='azure' plugin
...
Successfully enabled 'plugin' at 'azure'!
Tests
If you are developing this plugin and want to verify it is still functioning (and you haven't broken anything else), we recommend running the 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'
Acceptance Tests
Acceptance tests requires Azure access, and the following to be installed:
You will need to be properly logged in to Azure with your subscription set. See 'Azure Provider: Authenticating using the Azure CLI' for more information.
$ make test-acceptance AZURE_TENANT_ID=<your_tenant_id>
Setting WITH_DEV_PLUGIN=1
will first build the local plugin, and automatically register
it with the test Vault instance.
$ make test-acceptance AZURE_TENANT_ID=<your_tenant_id> WITH_DEV_PLUGIN=1
Running tests against Vault Enterprise requires a valid license, and specifying an enterprise docker image:
$ make test-acceptance AZURE_TENANT_ID=<your_tenant_id> \
VAULT_LICENSE=........ \
VAULT_IMAGE=hashicorp/vault-enterprise:latest
The test-acceptance
make target also accepts the following environment based directives:
TESTS_FILTER
: a regex of Bats tests to run, useful when you only want to run a subset of the tests.
