问题
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
回答1:
Use this command
docker run -d -it --privileged ContainerId /usr/sbin/init
And access root in container
systemctl start httpd.service
This should work!
回答2:
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.
