Chapter 5. Automation mesh nodes
Automation mesh is an overlay network that distributes automation work across large and distributed collections of workers through peer-to-peer node connections. Included are the tested system configurations and network port requirements for mesh nodes.
5.1. Tested system configurations
Each automation mesh VM has been tested with these requirements: 16 GB RAM, 4 CPUs, 60 GB local disk, and 3000 IOPS.
5.2. Network ports
Automation mesh uses several ports to communicate with its services. These ports must be open and available for Red Hat Ansible Automation Platform to work. Ensure that these ports are available and are not blocked by a firewall.
| Port number | Protocol | Service | Source | Destination |
|---|---|---|---|---|
| 80/443 | HTTP/HTTPS | Receptor | Execution node | OpenShift Container Platform mesh ingress |
| 80/443 | HTTP/HTTPS | Receptor | Hop node | OpenShift Container Platform mesh ingress |
| 27199 | TCP | Receptor | OpenShift Container Platform cluster | Execution node |
| 27199 | TCP | Receptor | OpenShift Container Platform cluster | Hop node |
