Air carrier pilot reported seeing a UAS pass near their aircraft while climbing through 600 feet. The reporter continued to fly a normal departure and notified ATC about their observation.

Narrative

On initial climb out; prior to thrust reduction at approximately 600 feet AGL; two small red lights appeared just off the nose and slightly left of the aircraft. As the aspect changed; there became 3 red lights. It was apparent that this was a drone. The drone passed just outside my window (left side). Our speed was approximately 160 kts so it went by rapidly. The three of us colorfully acknowledge the passing of the drone and a call was made to ATC to report the drone. We then began to assess for possible damage. After configuration clean up and established on a departure course we determined that from our seats; there was no impact. As a precaution; we contacted all the Flight Attendants; explained what had happened and asked if anyone heard anything unusual. None were observed. The flight continued to destination uneventfully. Upon arrival a 'post-flight inspection' was made to the best of our abilities considering that it was an international flight and we were unable to access the ramp due to customs regulations. No damage could be seen at that time from our vantage point. Between the three cockpit crew members we felt that the drone passed no more than 15 feet from the aircraft; eye level with me; yet made no impact. The red lights were on the corners of this drone. We passed close enough that the red glow of the drones lights reflected off its arms which were white and looked like bowling pins. Some idiot was flying a drone on or near the airport. Don't let idiots or smart people fly drones on or near airports.
