Edge Node Startup & Update Communication Process

Summary

Below is a step by step description of how a healthy Edge Node starts up and connects to the Trustgrid system.

Startup Process

  1. ARP for the default gateway

  2. DNS request for A record for gatekeeper.trustgrid.io & zuul.trustgrid.io

    1. The response will be IPs in the Trustgrid AWS networks:

      1. 35.171.100.16/28 US-EAST1

      2. 34.223.12.192/28 US-WEST-2

  3. The node will initiate a connection to port 8443 on the IP addresses returned and start a TLS handshake.

  4. After a successfully TLS handshake, the node will show as connected in the Trustgrid Portal

     

Update Process

  1. DNS request for A record of repo.trustgrid.io

    1. The response will be an IP in the Trustgrid AWS networks:

      1. 35.171.100.16/28 US-EAST1

      2. 34.223.12.192/28 US-WEST-2

  2. The node will initiate a connection to port 443 on the ip address returned for repo.trustgrid.io

  3. The update process will download any updated packages using port
