Cortex Installation Software Requirements

Cortex installation requires specific software components at specific versions, depending on the installation method. Elasticsearch is the only backend service Cortex relies on to store its data.

Package installationDocker Compose deploymentKubernetes deployment with Helm

• Java 11+

• Elasticsearch:

  Cortex version	Elasticsearch
  4.x	8.x
  3.2.1 and earlier	7.x

Sharing a single Elasticsearch instance between TheHive and Cortex isn't recommended. If you must do it, ensure the Elasticsearch version is compatible with both applications.

Docker Engine	Docker Compose plugin
v23.0.15+	v2.20.2+

Kubernetes cluster	Helm
v1.23.0+	v3.8.0+
