Here is my docker version output:
[root@docker-dtr ~]# docker version
API version: 1.24 (downgraded from 1.26)
Go version: go1.7.5
Git commit: 60ccb22
Built: Thu Feb 23 10:54:03 2017
API version: 1.26 (minimum version )
Go version: go1.7.1
Git commit: 12c8921
Built: Tue Nov 22 15:27:57 UTC 2016
Why Client API version is 1.24 (downgraded from 1.26)? I removed and reinstalled Docker engine a couple times, and did not help.
How to bring up API version to 1.26?
