Release 0.20#

2021-11-17

Templated topologies#

In #658 @karimra added support for templated topologies. This feature allows users to generate topology files based on the variables defined in a file. With templates, users can create a template once and then deploy different flavors of the topologies by using variables files, which are naturally smaller and way more human-readable.

Check the lab examples for addition details.

Limiting CPU and Memory resources for nodes#

In #679 @karimra adds resource limitation capabilities for the nodes. It is possible to limit the amount of available CPU, Memory and allocate specific cores to the nodes.
