Failed to get D-Bus connection: Operation not permitted

Question

I\'m trying to install ambari 2.6 on a docker centos7 image but in the the ambari setup step and exactly while initializing the postgresql db I receive this error:

Answer 1

On Centos7 all the services are started and stopped throught the systemd daemon. The systemctl command will simply try to talk to the daemon by using a d-bus channel - and that's where the message comes from.

Instead of running a container in priviledged mode (so it is not really contained) you could also try out the docker-systemctl-replacement to avoid the situation.
