{code}

*Background:*

This caused due to centos 7 using systemd by default and switched to use of {{systemctl}} command instead of {{service}}. Since that, service command exist only in backward compatibility context and r optional. Currently optional package, which provides this package called {{initscripts}}

Currently, everything ok r with standalone centos 7 image and it includes this package installed by default. However docker image centos/centos:7 doesn't provide this package by default, and systemd enabled image centos/systemd:latest use {{systemctl}} without installed {{initscripts}}: https://github.com/CentOS/sig-cloud-instance-images/issues/28

*Summary:*

Due to {{service}} command going to be deprecated, we need consider to switch fully to {{systemctl}} replacement for systemd enabled images
