Node Agent

Overview

Node Agent is part of the Edge Manageability Framework. It is responsible to register and authenticate the Edge Node with the Edge Infrastructure Manager service when the Edge Node is first brought up. It is also responsible for creating and refreshing tokens for other agents running on the Edge Node. It reports status of Edge Node to the Edge Infrastructure Manager as it onboards.

It:

Registers and authenticates Edge Node with Edge Infrastructure Manager service
Reports status of Edge Node to the Edge Infrastructure Manager as it onboards
Creates and refreshes tokens for other agents running on the Edge Node

Develop

To develop Node Agent, the following prerequisites are required:

The required Go version for the agents is outlined here.

Building the Node Agent

Binary Build

Run the make nabuild command to build the node agent binary. The compiled binary can be found in the build/artifacts directory.

Example:

$ cd node-agent/
$ make nabuild
$ ls build/artifacts/
node-agent

Debian Package Build

Run the make package command to build the node agent Debian package. The package can be found in the build/artifacts directory.

Example

$ cd node-agent/
$ make package
$ ls build/artifacts/
node-agent_<VERSION>_amd64.build  node-agent_<VERSION>_amd64.buildinfo  node-agent_<VERSION>_amd64.changes  node-agent_<VERSION>_amd64.deb  package

Source tarball

Run the make tarball command to generate a tarball of the node agent code. The tarball can be found in the build/artifacts directory.

Example

$ cd node-agent/
$ make tarball
$ ls build/artifacts/
node-agent-<VERSION>  node-agent-<VERSION>.tar.gz

Running the Node Agent Binary

To run the node agent binary after compiling:

./build/artifacts/node-agent -config configs/node-agent.yaml

Installing the Node Agent

The node agent Debian package can be installed using apt:

sudo apt install -y ./build/artifacts/node-agent_<VERSION>_amd64.deb

Uninstalling the Node Agent

To uninstall the node agent, use apt:

sudo apt-get purge -y node-agent
