Image Artist: Communication Pathways and Firewall Requirements for Harmony 5.3

This article describes the network communication and firewall requirements for transferring image data from Harmony 5.3.1 to Image Artist.

Important

Harmony performs an ICMP ping when validating the Image Artist host URL. Firewalls must allow ICMP traffic between the Harmony host and the Image Artist host for the connectivity check to succeed.

Firewall Requirements

Image Artist Host

Required

• TCP 443 (HTTPS)

Required only when Image Artist is configured with local storage

• TCP 9500 (MinIO)

Harmony Host (Optional)

Required only when Image Artist is configured with external object storage, such as:

• Amazon S3
• Google Cloud Storage
• NetApp StorageGRID

In these deployments, the Harmony host must be able to access the configured object storage endpoint.

Communication Pathway

All communication is initiated by Harmony.

1. Connection Establishment

Harmony connects to the Image Artist host over TCP 443.

2. Data Transfer

The data transfer method depends on the Image Artist storage configuration:

• Local storage – Harmony uploads image data to the MinIO service running on the Image Artist host over TCP 9500.
• External object storage – Harmony uploads image data directly to the configured object storage endpoint (for example, Amazon S3, Google Cloud Storage, or NetApp StorageGRID).

3. Status Monitoring

Harmony periodically polls Image Artist for job status updates over TCP 443.
