Vault Ruby Client

Vault is the official Ruby client for interacting with Vault by HashiCorp.

Quick Start

Install Ruby 2.0+: Guide.

Please note that Vault Ruby may work on older Ruby installations like Ruby 1.9, but you should not use these versions of Ruby when communicating with a Vault server. Ruby 1.9 has reached EOL and will no longer receive important security patches or maintenance updates. There are known security vulnerabilities specifically around SSL ciphers, which this library uses to communicate with a Vault server. While many distros still ship with Ruby 1.9 as the default, you are highly discouraged from using this library on any version of Ruby lower than Ruby 2.0.

Install via Rubygems:

$ gem install vault

or add it to your Gemfile if you're using Bundler:

gem "vault", "~> 0.1"

and then run the bundle command to install.

Start a Vault client:

Vault.address = "http://127.0.0.1:8200" # Also reads from ENV["VAULT_ADDR"]
Vault.token   = "abcd-1234" # Also reads from ENV["VAULT_TOKEN"]

Vault.sys.mounts #=> { :secret => #<struct Vault::Mount type="generic", description="generic secret storage"> }

Usage

The following configuration options are available:

Vault::Client.configure do |config|
  # The address of the Vault server, also read as ENV["VAULT_ADDR"]
  config.address = "https://127.0.0.1:8200"

  # The token to authenticate with Vault, also read as ENV["VAULT_TOKEN"]
  config.token = "abcd-1234"

  # Proxy connection information, also read as ENV["VAULT_PROXY_(thing)"]
  config.proxy_address  = "..."
  config.proxy_port     = "..."
  config.proxy_username = "..."
  config.proxy_password = "..."

  # Custom SSL PEM, also read as ENV["VAULT_SSL_CERT"]
  config.ssl_pem_file = "/path/on/disk.pem"

  # Use SSL verification, also read as ENV["VAULT_SSL_VERIFY"]
  config.ssl_verify = false

  # Timeout the connection after a certain amount of time (seconds), also read
  # as ENV["VAULT_TIMEOUT"]
  config.timeout = 30

  # It is also possible to have finer-grained controls over the timeouts, these
  # may also be read as environment variables
  config.ssl_timeout  = 5
  config.open_timeout = 5
  config.read_timeout = 30
end

If you do not want the Vault singleton, of if you need to communicate with multiple Vault servers at once, you can create indepenent client objects:

client_1 = Vault::Client.new(address: "https://vault.mycompany.com")
client_2 = Vault::Client.new(address: "https://other-vault.mycompany.com")

Making requests

All of the methods and API calls are heavily documented with examples inline using YARD. In order to keep the examples versioned with the code, the README only lists a few examples for using the Vault gem. Please see the inline documentation for the full API documentation. The tests in the 'spec' directory are an additional source of examples.

Seal Status

Vault.sys.seal_status
#=> #<Vault::SealStatus sealed=false, t=1, n=1, progress=0>

Create a Secret

Vault.logical.write("secret/bacon", delicious: true, cooktime: "11")
#=> #<Vault::Secret lease_id="">

Retrieve a Secret

Vault.logical.read("secret/bacon")
#=> #<Vault::Secret lease_id="">

Seal the Vault

Vault.sys.seal #=> true

Development

1. Clone the project on GitHub
2. Create a feature branch
3. Submit a Pull Request

Important Notes:

• All new features must include test coverage. At a bare minimum, Unit tests are required. It is preferred if you include acceptance tests as well.
• The tests must be be idempotent. The HTTP calls made during a test should be able to be run over and over.
• Tests are order independent. The default RSpec configuration randomizes the test order, so this should not be a problem.
