FIWARE Lab user creation service

Script to create automatically FIWARE Lab users taking the information from the Google Forms used yo created new FIWARE Lab user account and the information from the JIRA tickets in order to contrast the information from two sources previously to create the new account.

Overall description

The procedure to create a new FIWARE Lab user account has been updated after the migration from the FIWARE GE Keyrock to the OpenStack Keystone. This means that the use of authentication process how it was defined in the previous FIWARE Lab have had redefined.

The new procedure was defined in order to follow with the same level of requirements that used previously. It means that we have to check the domain email in order to exclude some blacklist of domains. The main purpose of this functionality is to prevent the email engine generation mails and use only those email domains in which we could be sure that are used only for genuine purpose. The defined system should allow the dynamic definition of new excluded emails domain.

A new requirements in included in this procedure. We wanted to check that the email is confirmed. It means that the creation of a new FIWARE Lab user account will be only available if and only if the user confirm the code that he receives by email after the introduction of the corresponding data in a portal. In this way we also prevent possible attacks in the creation of email accounts, due to we wait confirmation of the email before starting the automatic process of the new user creation.

In order to resolve these requirements, we created a specific Google Form with the corresponding Google Spreadsheet and the Google script code to cover those requirements.

Although, all the process is almost automatic, there is a special step that is made manually. This one is the review of the confirmation email. We decided to do it manually due to prevent the automatic user generation account. It that way, at administrator have to validate the reception of the request and confirm that the new user has sent the corresponding email. After this operation, the administrator will create a specific JIRA ticket in our ticketing system with the corresponding information to create the new user and assign it to the corresponding FIWARE Lad node administrator in order to create it.

Once that the administrator has confirmed the reception of the email and the creation of the corresponding ticket in JIRA, the automatic user creation service start to work. This service periodically wake up and see if there is a confirmed email in the Google Spreadsheet whose ticket in JIRA is still open. In that case, it means that the user was not created and proceed with the creation of the user in the OpenStack Keystone service.

Build and Install


The following software must be installed:

  • Python 3.7
  • pip
  • virtualenv


The recommend installation method is using a virtualenv. Actually, the installation process is only about the python dependencies, because the python code do not need installation.

  1. Clone this repository.
  2. Define the configuration file in './config/user-create.ini'
  3. Create your Google Credential in the './config/user-credential.json' file.
  4. Create your Google service account key in the './config' directory
  5. Execute the script 'source'.
  6. With root user, execute the command 'cp ./config/user-create.logrotate /etc/logrotate.d/user-create'.


Once that you have installed and configured your application, you can run it just executing:


And it will be executed in order to create the corresponding account. Keep in mind that you have to be inside a previously defined virtual environment.

The file that you can find in the deploy folder is used in order to allow the automatic execution of the python script just adding the corresponding header to the file:

#!/usr/bin/env /env/bin/python

Where env is the name of your virtual environment.

Last but not least, the service is added into the crontab service of the machine in order to execute the service each 30 minutes to check if a new account is needed to be created.


There is a specific option to deploy this service in a host. Take a look to the content of deploy directory


Unit Tests

It was defined a minimum set of tests to cover the core functionality of the service. The tests target is used for running the unit tests in the component. We use for those tests the tox tool. Tox is a generic virtualenv management and test command line tool you can use for checking your package installs correctly with different Python versions and interpreters running your tests in each of the environments, configuring your test tool of choice acting as a frontend to Continuous Integration servers, greatly reducing boilerplate and merging CI and shell-based testing.

The configuration file can be found in tox.ini in which we have defined two different environments:

  • The first one, to test the service using nosetests.
  • The second one, to check the python coding style using pycodestyle

First of all, you need to install the tool with the following commands:

pip install tox

Now, you can run the tests, simply execute the commands:



The support of this service is under github. You can create your issues and they will be resolved by the development team in the following sprint.
