Thanks for responding. There really isn't many more details other than that. It was in DockerCon Seattle in the space needle. I don't remember who the employee was. I did generally get the feeling that Docker employees felt at least wary or worse about k8s. That was from more than just that once situation, but from multiple interactions I had over the conference with employees. I only pointed out that one interaction because it made me certain that at least that employee was more than wary.
I'm happily using Docker and it was a good conference otherwise.
