Talos Linux and Kubernetes

EDA uses Talos Linux and Kubernetes to host its services in. Talos Linux is a minimalistic, locked-down, read-only and secured Linux environment in which Kubernetes is run. This assures a more secure environment with significantly lower security footprint than regular Linux and Kubernetes environments.

edaadm

The edaadm tool is used for the following steps in the installation process:

getting the location to download the base Talos image for KVM and VMware environments.
generating the Talos machine configuration files for the deployment of both the Assets VM and the EDA Kubernetes cluster VMs.
initiating Talos Kubernetes clusters.
