That's not UEK3. That's the CentOS RHCK. UEK3 is 3.8 and we don't support Docker on that kernel anyway. Can you reproduce this issue on Oracle Linux 7 running UEK4 (4.1.12)?

HI Djelibeybi

Thanks for your update.

You are right. l don't reproduce this issue on UEK4. It can work.

Great. Closing this as it works on our supported platform.
