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.

Security Model

This authentication model places Vault in the middle of a call between a client and TencentCloud's "GetCallerIdentity" method. Based on TencentCloud's response, it grants an access token based on pre-configured roles.

Usage

Please see documentation for the plugin

From Sources

If you prefer to build the plugin from sources, clone the GitHub repository locally.

Build the plugin

Build the auth method into a plugin using Go.

$ go build -o vault/plugins/vault-plugin-auth-tencentcloud ./cmd/vault-plugin-auth-tencentcloud/main.go

Configuration

Copy the plugin binary into a location of your choice; this directory must be specified as the plugin_directory in the Vault configuration file:

plugin_directory = "vault/plugins"

Start a Vault server with this configuration file:

$ vault server -config=vault/server.hcl

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

$ SHA256=$(shasum -a 256 vault/plugins/vault-plugin-auth-tencentcloud | cut -d ' ' -f1)

$ vault plugin register -sha256=$SHA256 auth vault-plugin-auth-tencentcloud

$ vault plugin info auth vault-plugin-auth-tencentcloud

You can now enable the tencentCloud auth plugin:

$ vault auth enable -path=tencentcloud vault-plugin-auth-tencentcloud
Success! Enabled vault-plugin-auth-tencentcloud auth method at: tencentcloud/

Developing

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

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-auth-tencentcloud. 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

For local development, use Vault's "dev" mode for fast setup:

$ vault server -dev -dev-plugin-dir="path/to/plugin/directory"

The plugin will automatically be added to the catalog with the name "vault-plugin-auth-tencentcloud". Run the following command to enable this new auth method as a plugin:

$ vault auth enable -path=tencentcloud vault-plugin-auth-tencentcloud
Success! Enabled vault-plugin-auth-tencentcloud auth method at: tencentcloud/

Tests

This plugin has comprehensive acceptance tests covering most of the features of this auth backend.

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 acceptance tests.

Warning: The acceptance tests create/destroy/modify real resources, which may incur real costs in some cases. In the presence of a bug, it is technically possible that broken backends could leave dangling data behind. Therefore, please run the acceptance tests at your own risk. At the very least, we recommend running them in their own private account for whatever backend you're testing.

To run the acceptance tests, you will need a TencentCloud account.

To run the acceptance tests, invoke make test-acc:

$ export VAULT_ACC_TEST_SECRET_ID=YOU 
$ export VAULT_ACC_TEST_SECRET_KEY=YOU SECRET KEY
$ export VAULT_ACC_TEST_TOKEN=YOU SECRET TOKEN (if you run as a CAM role, VAULT_ACC_TEST_TOKEN is required)
$ export CLIENT_CONFIG_TEST_SECRET_ID=CLIENT CONFIG SECRET ID
$ export CLIENT_CONFIG_TEST_SECRET_KEY=CLIENT CONFIG SECRET KEY
$ make test-acc

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

$ make test-acc TESTARGS='--run=TestConfig'

To run the integration tests, invoke make test:

$ make test

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

$ make test TESTARGS='--run=TestConfig'
