How to pronounce Piraeus

Piraeus is most commonly pronounced "pie ree us" (/paɪˈriːəs/). This is the widely-used reading among engineers, though edge cases exist.

Piraeus Datastore is a CNCF sandbox project providing LINSTOR/DRBD-based replicated block storage for Kubernetes, a common Longhorn/OpenEBS alternative on bare-metal clusters; it is named after Greece's great port, Πειραιάς. The dominant English reading is "py-REE-us" — the -aeus ending is a trap that invites "PIE-ray-oos" or stress on the first syllable. Note that "pih-RAY-us" is not an error but a documented secondary variant: Wikipedia, Collins and Dictionary.com all list both /paɪˈriːəs/ and /pɪˈreɪəs/.

Alternate readings you might hear:

• "pih ray us" /pɪˈreɪəs/

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
