Trying to configure Nova-Docker for DevSatck using the official guide here. I keep on having the error /opt/stack/devstack/.localrc.auto: line 147: [DEFAULT]: command not found. As an alternative, I commented out the "[DEFAULT]"and the installation went on fine but failed again with the error "n-cpu failed to start". I am not sure of the next step to take...any help is well appreciated, thanks in advance.
