Updating Docker?

I’ve recently purchased a WD My Cloud EX2 Ultra, and while it works fine, I’ve only now discovered that it’s running an ancient version of docker - 1.7.0, build 0baf609.

Now, I’d like to use Portainer to manage my Docker images, but since it’s an unsupported version, I am not able to use it.

Is there any way to update Docker to a newer version?

The same problem by me…
with My EX4100

On my Server i work with Ubuntu there works everything fine… but in this BusyBox it doesnt…

I hope someone can help us… -.-
