The following two videos give a theoretical overview of the TOSCA specification. It is presented by one of ARIA's developers, Tal Liron. In this session, Tal talks about the TOSCA Simple Profile in YAML and its implementation in ARIA.
The slides are available here.
There are multiple ways of installing and running ARIA TOSCA. Specifically, there essentially two different branches of installations: user and developer. Both are documented below.
While the instructions below strive to be complete, we‘re human and make mistakes from time to time. In situations where something doesn’t work as described, do not hesitate to reach out to the community for assistance by sending email to firstname.lastname@example.org
ARIA TOSCA is available on PyPI.
ARIA TOSCA requires Python 2.6/2.7. Python 3 is currently not supported.
To install ARIA TOSCA directly from PyPI (using a
pip install --upgrade pip setuptools pip install apache-ariatosca
To install ARIA TOSCA from source, download the source tarball from PyPI, extract and
cd into the extract dir, and run::
pip install --upgrade pip setuptools pip install .
| The source package comes along with relevant examples, documentation,
requirements.txt (for installing specifically the frozen dependencies' versions with which ARIA TOSCA was tested) and more. | | | ARIA TOSCA has additional optional dependencies. These are required for running operations over SSH. | Below are instructions on how to install these dependencies, including required system dependencies per OS. | | Note: These dependencies may have varying licenses which may not be compatible with Apache license 2.0. |
Ubuntu/Debian (tested on Ubuntu14.04, Ubuntu16.04)::
apt-get install -y python-dev gcc libffi-dev libssl-dev pip install apache-ariatosca[ssh]
Centos (tested on Centos6.6, Centos7)::
yum install -y python-devel gcc libffi-devel openssl-devel pip install apache-ariatosca[ssh]
pacman -Syu --noconfirm python2 gcc libffi openssl pip2 install apache-ariatosca[ssh]
Windows (tested on Win10)::
# no additional system requirements are needed pip install apache-ariatosca[ssh]
pip, either use your distro's package management system, or run::
wget http://bootstrap.pypa.io/get-pip.py python get-pip.py
Developers will want to pull their base code from github and then build from that locally. Note there are two code repositories for ARIA TOSCA: one for the website and one for the main code base. Instructions for pulling and running each are detailed below.
Ubuntu/Debian (tested on Ubuntu14.04, Ubuntu16.04):
apt-get install -y python-dev gcc libffi-dev libssl-dev git # In addition to the above, install the following for website development sudo apt-get install ruby-dev sudo gem install jekyll bundler # you may have to install jekyll's dependancies bundle install
Centos (tested on Centos6.6, Centos7):
yum install -y python-devel gcc libffi-devel openssl-devel # In addition to the above, install the following for website development sudo yum install ruby-dev sudo gem install jekyll bundler # you may have to install jekyll's dependancies bundle install
Building from your pulled code :
Instructions are here
The website is created using the Jekyll system. Launch the web server using the following and then browse to the URL indicated by jekyll's output: bundle exec jekyll serve
This section will describe how to run a simple “Hello World” example.
First, provide ARIA TOSCA with the ARIA TOSCA“hello world” template (can be downloaded here) service-template and name it (e.g.
aria service-templates store examples/hello-world/hello-world.yaml my-service-template
Now create a service based on this service-template and name it (e.g.
aria services create my-service -t my-service-template
Finally, start an
install workflow execution on
my-service like so:
aria executions start install -s my-service
You should now have a simple web-server running on your local machine. You can try visiting
http://localhost:9090 to view your deployed application.
To uninstall and clean your environment, follow these steps:
aria executions start uninstall -s my-service aria services delete my-service aria service-templates delete my-service-template
