HashiCorp Vault Plugins for Redis Enterprise

Vault Database Secrets Engine - Redis Enterprise Plugin

A Redis Enterprise plugin for the HashiCorp Vault Database Secrets Engine.

This is a standalone backend plugin for use with Hashicorp Vault. This plugin generates credentials for use with Redis Enterprise Database clusters.

Development

If you wish to work on this plugin, you'll first need Go installed on your machine (version 1.15+ is required).

Make sure Go is properly installed, including setting up a GOPATH.

To run the tests locally you will need to have Docker installed on your machine, or have access to a Kubernetes cluster such as by using kind.

Clone this repository:

$ git clone https://github.com/RedisLabs/vault-plugin-database-redis-enterprise
$ cd vault-plugin-database-redis-enterprise

or use go get github.com/RedisLabs/vault-plugin-database-redis-enterprise

Building

To compile this plugin, run make build. This will put the plugin binary in a local bin directory. By default, this will generate a binary for your local platform and a binary for linux/amd64.

$ make build

Testing

Before being able to run the tests, you need to have access to a running Redis Enterprise Cluster. This can either be done by using the Redis Enterprise Operator to deploy Redis into Kubernetes, or by using the Redis Enterprise container which can be started up locally by running make start-docker.

To execute the tests run make or make test.

$ make test

The plugin's makefile contains default values to locate a Redis Enterprise cluster provisioned through the makefile. The following example shows how these values can be overridden to locate your own cluster.

$ export TEST_USERNAME=admin
$ export TEST_PASSWORD=xyzzyxyzzy
$ export TEST_DB_NAME=mydb
$ export TEST_DB_URL=https://localhost:9443

$ make test

Running Vault + Plugin + Redis Enterprise

The repo provides a means to run a local Vault server configured with the Vault Plugin and backed by a Redis Enterprise cluster. To start the Vault server and Redis Enterprise cluster run make start-docker followed by make configure-docker to configure Vault with a locally built plugin binary.

$ make start-docker

cd bootstrap && docker-compose up --detach
Creating network "bootstrap_vault" with the default driver
Creating bootstrap_v_1  ... done
Creating bootstrap_rp_1 ... done
./bootstrap/redis-setup.sh -u admin -p xyzzyxyzzy -db mydb
waiting for the container to finish starting up
...
waiting for the container to finish starting up
waiting for cluster bootstrap
...
waiting for cluster bootstrap
waiting for database setup
done

$ make configure-docker
...

A docker compose file representing a Redis Enterprise cluster and a Vault server will be provisioned. Once setup is complete run make test to execute the acceptance test against the local containers.

$ make test

After local testing is complete the docker containers can be removed through the make stop-docker.

$ make stop-docker

cd bootstrap && docker-compose down
Stopping bootstrap_rp_1 ... done
Stopping bootstrap_v_1  ... done
Removing bootstrap_rp_1 ... done
Removing bootstrap_v_1  ... done
Removing network bootstrap_vault

Building for Multiple Architectures

Vault operates across a number of different architectures and as a result Vault plugins must also be built to execute across the same architectures. This repo supports building the appropriate binaries through goreleaser and these steps are coordinated through the repo's GitHub Action workflows. To test changes to the goreleaser configuration or to build the different binaries locally the following command can be executed.

$ goreleaser --snapshot --skip-publish --rm-dist

A dist directory will be created and there will be one binary for each OS/Arch combination defined in the root goreleaser.yml file. A SHA256SUMS file will also be produced with entries for each binary.
The SHA values can be used when installing the plugin to a running Vault server.

Note: If you are running Vault via Docker the plugin architecture if likely to be linux/amd64. This binary is also produced through the make build
