Vault Benchmark

vault-benchmark is a tool designed to test the performance of Vault auth methods and secret engines. Running the binary with a benchmark configuration file, will configure any necessary resources on the Vault instance itself required to perform the tests defined. Any auth methods or secrets engine tests defined that require an external dependency such as a database will require that infrastructure be set up correctly prior to benchmarking. vault-benchmark makes use of the Vegeta HTTP load testing utility.

Warning vault-benchmark will put a great amount of stress against the cluster itself and the infrastructure that the cluster is running on during testing, and as such is intended to only be run against a test Vault cluster that is isolated from any production systems or any other systems that can cause any negative impact.

Installation

Official Release Binaries

You can download a release binary from our release page

Compiling From Source

You can compile the latest version including any fixes or features from source by running make bin. This will put the vault-benchmark binary in the dist folder in directories that map to your GOOS and GOARCH:

$ make bin
GOARCH=arm64 GOOS=darwin go build -o dist/darwin/arm64/vault-benchmark

Usage

vault-benchmark can be run directly as a binary, docker container or kubernetes job. Below is an example of running the binary.

First a configuration file needs to be created defining the basic vault-benchmark settings as well as defining which benchmark tests to be run. For Example:

# Basic Benchmark config options
vault_addr = "http://127.0.0.1:8200"
vault_token = "root"
vault_namespace="root"
duration = "30s"
cleanup = true

test "approle_auth" "approle_logins" {
  weight = 50
  config {
    role {
      role_name = "benchmark-role"
      token_ttl="2m"
    }
  }
}

test "kvv2_write" "static_secret_writes" {
  weight = 50
  config {
    numkvs = 100
    kvsize = 100
  }
}

This test configuration will run two different benchmark tests, an approle_auth test, and a kvv2_write test, with the percentage of requests being split evenly between the two.

Then we run the binary and provide the configuration file path:

$ vault-benchmark run -config=config.hcl

Docker

Tip: Create a Vault Benchmark image with the make image command.

First, create a network that Vault and Vault Benchmark will share:

docker network create vault

Next, deploy Vault to Docker and ensure it's running:

docker run \
  --name=vault \
  --hostname=vault \
  --network=vault \
  -p 8200:8200 \
  -e VAULT_DEV_ROOT_TOKEN_ID="root" \
  -e VAULT_ADDR="http://localhost:8200" \
  -e VAULT_DEV_LISTEN_ADDRESS="0.0.0.0:8200" \
  --privileged \
  --detach hashicorp/vault:latest

docker logs -f vault

Once Vault is running, create a Vault Benchmark container and watch the logs for the results:

docker run \
  --name=vault-benchmark \
  --hostname=vault-benchmark \
  --network=vault \
  -v ./vault-benchmark/configs/:/opt/vault-benchmark/configs \
  --detach hashicorp/vault-benchmark:latest \
  vault-benchmark run -config=/opt/vault-benchmark/configs/config.hcl

docker logs -f vault-benchmark
