This is an overview of the features and changes added in the latest version of Nerve. For an extensive list of all changes, refer to the release notes. For more details on each feature, follow the links after the feature descriptions.

Nerve DNA

Nerve DNA, short for Deterministic Node Automation, is an infrastructure as code mechanism introduced to ease node configuration. Working in a declarative way of configuration, the system compares a target configuration file to the current configuration file and takes the required steps to reach the target configuration in an automated process, in which the node will install workloads from the Management System workload repository.

Refer to Nerve DNA for more information.

New workload type: Docker Compose

Docker Compose workloads have been introduced as a different way of working with Docker containers in the Nerve system. In this version, Docker Compose workloads are used for one Docker container and give users the possibility to use a Docker container in combination with a compose file to use the full extent of Docker Compose.

Docker Compose

Refer to Provisioning a Docker Compose workload for more information.

New workload deployment work flow

The workload deployment process can now be started from the workloads menu. A Deploy button is available for every workload version in the list of workload versions.

Nerve as a VM

The Nerve system can now be run in a VM, running without hypervisor and independent of a device. This variant of Nerve does not have a RTVM and can be installed on CPUs without VT-D.

The documentation covers two ways of running Nerve in a VM — using VMware and virt-manager.
