#app_id(app_id, user_id, options = {}) ⇒ Secret

Authenticate via the “app-id” authentication method. If authentication is successful, the resulting token will be stored on the client and used for future requests.

Examples:

Vault.auth.app_id(
  "aeece56e-3f9b-40c3-8f85-781d3e9a8f68",
  "3b87be76-95cf-493a-a61b-7d5fc70870ad",
) #=> #<Vault::Secret lease_id="">

with a custom mount point

Vault.auth.app_id(
  "aeece56e-3f9b-40c3-8f85-781d3e9a8f68",
  "3b87be76-95cf-493a-a61b-7d5fc70870ad",
  mount: "new-app-id",
)

Parameters:

  • app_id (String)
  • user_id (String)
  • options (Hash) (defaults to: {}) —

    additional options to pass to the authentication call, such as a custom mount point

Returns:

  secret = Secret.decode(json)
  client.token = secret.auth.client_token
  return secret
end

#approle(role_id, secret_id = nil) ⇒ Secret

Authenticate via the “approle” authentication method. If authentication is successful, the resulting token will be stored on the client and used for future requests.

#tls(pem = nil, path = 'cert') ⇒ Secret

Authenticate via a TLS authentication method. If authentication is successful, the resulting token will be stored on the client and used for future requests.

Examples:

Sending raw pem contents

Vault.auth.tls(pem_contents) #=> #<Vault::Secret lease_id="">

Reading a pem from disk

Vault.auth.tls(File.read("/path/to/my/certificate.pem")) #=> #<Vault::Secret lease_id="">

Sending to a cert authentication backend mounted at a custom location

Vault.auth.tls(pem_contents, 'custom/location') #=> #<Vault::Secret lease_id="">

Parameters:

  • pem (String) (defaults to: nil) —

    (default: the configured SSL pem file or contents) The raw pem contents to use for the login procedure.

  • path (String) (defaults to: 'cert') —

    (default: ‘cert’) The path to the auth backend to use for the login procedure.

  new_client = client.dup
  new_client.ssl_pem_contents = pem if !pem.nil?

  json = new_client.post("/v1/auth/#{CGI.escape(path)}/login")
  secret = Secret.decode(json)
  client.token = secret.auth.client_token
  return secret
end

#token(new_token) ⇒ Secret

Authenticate via the “token” authentication method. This authentication method is a bit bizarre because you already have a token, but hey, whatever floats your boat.

This method hits the ‘/v1/auth/token/lookup-self` endpoint after setting the Vault client’s token to the given token parameter. If the self lookup succeeds, the token is persisted onto the client for future requests. If the lookup fails, the old token (which could be unset) is restored on the client.

Examples:

Vault.auth.token("6440e1bd-ba22-716a-887d-e133944d22bd") #=> #<Vault::Secret lease_id="">
Vault.token #=> "6440e1bd-ba22-716a-887d-e133944d22bd"

Parameters:

  • new_token (String) —

    the new token to try to authenticate and store on the client

  secret = Secret.decode(json)
  return secret
rescue
  client.token = old_token
  raise
end

#userpass(username, password, options = {}) ⇒ Secret

Authenticate via the “userpass” authentication method. If authentication is successful, the resulting token will be stored on the client and used for future requests.

Examples:

Vault.auth.userpass("sethvargo", "s3kr3t") #=> #<Vault::Secret lease_id="">

with a custom mount point

Vault.auth.userpass("sethvargo", "s3kr3t", mount: "admin-login") #=> #<Vault::Secret lease_id="">

  • username (String)
  • password (String)
  • options (Hash) (defaults to: {}) —
