Python Container

Python Container on Github

With Direktiv's special command it is easy to use a standard Python container from Docker Hub. In the following example the flow uses one of those containers and uses the special command /usr/share/direktiv/direktiv-cmd to use it in Direktiv.

This special command eanbles the user to pass in files as well. Thisd can be done with the standard files in Direktiv's filesystem or on-demand like in this example. The file script.py is getting created when the function runs and can be executed because the permission is set to 0755. These scripts can contain flow variables and secrets as well if required.
