Application Lifecycle Deployment Engine (ALDE) is a component of the European Project TANGO (http://tango-project.eu ).
ALDE is distributed under a GNU AFFERO GENERAL PUBLIC LICENSE.
ALDE is responsible for the workload scheduling and the management of the application life-cycle while it is executed. ALDE will take the application source code, packetize for different heterogeneous architectures configurations and, if possible, deploy it via a TANGO Device Supervisor and manage the application execution.
More in detail each one of the previous steps:
- Compilation - ALDE is able to compile the application in different configurations depending of the selected heterogeneous architectures. The result will be a set of binaries optimal compiled for specific hardware architectures.
- Packetization - ALDE, once the application has been compiled, can packetize it. For the moment it only supports typical tar.gz files and Docker and Singularity containers.
- Deployment - ALDE is able to automatically deploy an application into a TANGO compatible Device Supervisor. It will launch the execution and monitor it. It will also support adaptations interactions if used in combination with the TANGO Self-Adaptation Manager.
This guide it is divided into two different guides, one specific to create an environment for development and another one to just run and use ALDE.
To develop for ALDE we need to install two pieces of software:
To develop ALDE it is necessary to create a Python Virtualenv (depending on your installation of Python pip3 command can be called pip):
$ pip3 install virtualenv
Collecting virtualenv
Downloading virtualenv-15.0.3-py2.py3-none-any.whl (3.5MB)
100% |████████████████████████████████| 3.5MB 398kB/s
Installing collected packages: virtualenv
Successfully installed virtualenv-15.0.3
After that, you need to create a virtualenv for you to develop:
$ virtualenv venv
Using base prefix '/Library/Frameworks/Python.framework/Versions/3.5'
New python executable in /Users/davidgp/Documents/trabajo/TANGO/repositorios/alde/venv/bin/python3.5
Also creating executable in /Users/davidgp/Documents/trabajo/TANGO/repositorios/alde/venv/bin/python
Installing setuptools, pip, wheel...done.
Now it time to install PyBuilder:
- First we activate the virtualenv:
$ source venv/bin/activate
- Now we install PyBuilder using Pip:
$ pip install pybuilder
Collecting pybuilder
Using cached PyBuilder-0.11.9.tar.gz
Requirement already satisfied: pip>=7.0 in ./venv/lib/python3.5/site-packages (from pybuilder)
Collecting tblib (from pybuilder)
Using cached tblib-1.3.0-py2.py3-none-any.whl
Requirement already satisfied: wheel in ./venv/lib/python3.5/site-packages (from pybuilder)
Building wheels for collected packages: pybuilder
Running setup.py bdist_wheel for pybuilder ... done
Stored in directory: /Users/davidgp/Library/Caches/pip/wheels/04/9c/b3/d2d2194e8911818abdfa1c3c47501a64602714415af28d8da8
Successfully built pybuilder
Installing collected packages: tblib, pybuilder
Successfully installed pybuilder-0.11.9 tblib-1.3.0
(venv)
Now it is possible to compile the project:
- Install first the dependencies:
$ pyb install_dependencies

Now, remember, each time you need to start to develop, initalize the virtualenv:
$ source venv/bin/activate
- Install Singularity - View doc

In this case, we are going to detail how to run the application directly using Python. It is possible to run it behind a proxy or webserver, to do so, please, check this guides.
ALDE employs a SQLite database server that needs to be configured together with the port were the service it is going to be listen. That configuration can be done editing the file alde_configuration.ini that contains these two variables:
[DEFAULT]
SQL_LITE_URL = sqlite:////tmp/test.db
PORT = 5000To install it, it is necessary to execute the following command:
python setup.py install
To launch the service we need to execute:
$ python app.py

After it we could verify it works just by execution the following (in this example we are using Curl but you could use another REST/http client):
$ curl localhost:5000/api/v1/testbeds
{
"num_results": 0,
"objects": [],
"page": 1,
"total_pages": 0
}
Although a CLI client is planned, for the moment ALDE offers a REST interface.
The rest api is fully documented here: ( https://jsapi.apiary.io/previews/applicationlifecycledeploymentengine/reference/0/testbed )
Listing all applications available:
curl http://localhost:5000/api/v1/applications
Creating an application
$ curl -X POST -H'Content-type: application/json' http://127.0.0.1:5000/api/v1/applications -d'{ "name": "my_app" }'
{
"executables": [],
"execution_scripts": [],
"id": 1,
"name": "my_app"
}
Uploading zip file with the source code of the application. Pay attention to the two variables: compilation_type and compilation_script
$ curl -X POST -F "file=@test.zip" http://localhost:5000/api/v1/upload/1?compilation_type=SINGULARITY:PM\&compilation_script=./build.sh
file upload for app with id: 1
Seeing the status of the compilation (executable section):
$ curl http://localhost:5000/api/v1/applications/1
{
"executables": [
{
"application_id": 1,
"compilation_script": "compilation.sh",
"compilation_type": "singularity:pm",
"executable_file": null,
"id": 1,
"source_code_file": "f5a8e16b-6c36-4092-97cb-6081374d9b29.zip",
"status": "NOT_COMPILED"
}
],
"execution_scripts": [],
"id": 1,
"name": "my_app"
}
curl localhost:5000/api/v1/testbeds -X POST -H'Content-type: application/json' -d'{ "name": "slurm_testbed", "on_line": true, "category": "SLURM", "protocol": "SSH", "endpoint": "user@ssh.com"}'
ALDE can be used as an standalone tool in TANGO, it will allow to compile application for different targeted heterogenous architectures in an optimize way and with different configurations of heterogenous devices, but its fully potential it is with other TANGO components:
- Programming model and IDE tools - TANGO Programming Model can connect with ALDE to submit the code for compilation and packetization. Also it could be intereact with ALDE to submit the application directly to a TANGO compatible device supervisor.
- Device Supervisor - ALDE can interact with a on-line testbed that has installed a TANGO device supervisor on it. This will allow to automatically deploy diferent configurations of the application and execute it, monitoring the execution and extract back the results.
- Self-Adaptation Manager - ALDE will provide intefaces for the Self-Adaptation Manager to change the configuration of an application to optimize its execution in a TANGO compatible testbed.
