Overview

Nodes make up the strongDM network, and allow your users to connect securely to your resources. There are two types of nodes:

• Gateways are the entry points into network. They listen for connection from the strongDM client, and provide access to databases and servers.

• Relays are used to extend the strongDM network into segmented subnets. They provide access to databases and servers but do not listen for incoming connections.

Instance Method Summary

• #create(node, deadline: nil) ⇒ Object

  Create registers a new Node.

• #delete(id, deadline: nil) ⇒ Object

  Delete removes a Node by ID.

• #get(id, deadline: nil) ⇒ Object

  Get reads one Node by ID.

• #initialize(host, insecure, parent) ⇒ Nodes constructor

  A new instance of Nodes.

• #list(filter, *args, deadline: nil) ⇒ Object

  List gets a list of Nodes matching a given set of criteria.

• #update(node, deadline: nil) ⇒ Object

  Update patches a Node by ID.
