#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:

def app_id(app_id, user_id, options = {})
  payload = { app_id: app_id, user_id: user_id }.merge(options)
  json = client.post("/v1/auth/app-id/login", JSON.generate(payload))
  secret = Secret.decode(json)
  client.token = secret.auth.client_token
  return secret
end

#approle(role_id, secret_id = nil, options = {}) ⇒ Secret

  "db02de05-fa39-4855-059b-67221c5c2f63",
  "6a174c20-f6de-a53c-74d2-6018fcceff64",
  mount: "my-approle"
) #=> #<Vault::Secret lease_id="">

    (default: nil) It is required when bind_secret_id is enabled for the specified role_id

  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="">

Parameters:

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