Cortex is an intelligent service for initial placement and scheduling of compute workloads within an OpenStack cloud environment. It is designed to improve resource usage in a data center by making smart(er) decisions about where to place VMs, with future support planned for storage and network workloads.
Efficient and balanced resource utilization is key for cloud infrastructure providers to maintain operational performance and cost-effectiveness. In a dynamic cloud environment where workloads are constantly being created, moved, and deleted, a smart placement can help avoid resource bottlenecks and ensure high availability.
OpenStack provides core services for managing compute, storage, and network resources in a cloud environment (learn more). Cortex extends the scheduling logic of these services by adding a layer of intelligence that can make more informed decisions about where to place workloads based on the current state of the data center.
- Data sync: Flexible framework to sync metrics and placement information of a data center.
- Knowledge extraction: Logic to extract simple or advanced knowledge ("features") from the synced data.
- Smart scheduling: Fast and scalable scheduling pipeline for VMs based on the extracted knowledge.

Copy the example secrets values file. This file is used for local development and overrides the Helm chart values provided in values.yaml for your local testing setup.
cp cortex.secrets.example.yaml "${HOME}/cortex.secrets.yaml"Warning
It is recommended to put the secrets file somewhere outside of the project directory. In this way, it won't be accidentally committed to the repository.
After copying the file, fill in the necessary values.
Then, tell tilt where to find your secrets file:
export TILT_VALUES_PATH="${HOME}/cortex.secrets.yaml"Run the tilt setup in minikube:
minikube start && tilt upPoint your browser to http://localhost:10350/ - if you did everything correctly, you should see the cortex services spin up in the browser.
To simulate Nova requests to your Cortex instance in Tilt, you can run the following command:
go run commands/fillup/fillup.goThe script will show where random new VMs would be placed.
