Failed to get D-Bus connection: Operation not perm

Question

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

Failed to get D-Bus connection: Operation not permitted

I've got this error every time I try to run a serice on my docker image.

I tried every solution in the net but nothing worked yet.

Does any one have an idea how to resolve this ?

Thank you in advance

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.

Answer 2

Use this command

docker run -d -it --privileged ContainerId /usr/sbin/init

And access root in container

systemctl start httpd.service

This should work!
