When I read the introduction about the overlay2 storage driver on CentOS, I didn’t see whether it was clearly production available(as below table, overlay2 is not the recommended storage driver on centos, but when i yum install docker 1.13.1 on centos, defalut storage driver is overlay2). So i want to confirm it here, thank you very much for your answer.
ps: my centos version is 7.5.1804 (3.10.0-862.e17.x86_64) and defalut use overlay2.
