I’m new to Docker and I’m facing a problem when it comes to seeing existing containers or any other information.
When running for example : Docker ps. Displays the following error message: Cannot connect to the Docker daemon. Is the Docker daemon running on this host?
The OS I’m using is Linux Ubuntu
Grateful from now on.
I made the process informed, but the problem continues. Running the command 'service Docker start' presents the following message: "start: Rejected send message, 1 Matched Rules; type="method_call", Sender=":1.183" (uid=1000 pid=7036 com="start Docker ") interface="com.ubuntu.Upstart0_6.Job" Member="Start" error name="(unset)"requested_reply="0" Destination="com.ubuntu.Upstart" (uid=0 pid=1 Comm="/sbin/init") ". I’ll reinstall and try again.
