Using OpenTelekomCloud with the native python-openstackclient
Posted by ebal at 11:59:46 in blog

 

Open Telekom Cloud (OTC) is Deutsche Telekom’s Cloud for Business Customers. I would suggest to visit the Cloud Infrastructure & Cloud Platform Solutions for more information but I will try to keep this a technical post.

In this post you will find my personal notes on how to use the native python openstack CLI client to access OTC from your console.

Notes are based on Ubuntu 18.04.2 LTS

otcextensions

 

Virtual Environment

Create an isolated python virtual environment (directory) to setup everything under there:

~>  mkdir -pv otc/ && cd otc/
mkdir: created directory 'otc/'

~>  virtualenv -p `which python3`  .

Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/ebal/otc/bin/python3
Also creating executable in /home/ebal/otc/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
~>   source bin/activate

(otc) ebal@ubuntu:otc~>
(otc) ebal@ubuntu:otc~> python -V
Python 3.6.7

 

OpenStack Dependencies
