Systemctl/service commands are not working on a container which is built by using centos:centos7 image.

Can anybody help me here?

  • Are you getting a specific error? You may be able use a docker logs command to get the error message from the container if it isn't outputting it to the console. – Wesley Rolnick Aug 26 '19 at 14:11

Using systemd in Docker is not really that straightforward.

However, according to the doc on the docker hub, systemd is now included in both the centos:7 and centos:latest base containers.
However, you will need to include text similar to the example Dockerfile :

FROM centos:7
ENV container docker
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == \
systemd-tmpfiles-setup.service ] || rm -f $i; done); \
rm -f /lib/systemd/system/multi-user.target.wants/*;\
rm -f /etc/systemd/system/*.wants/*;\
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*;\
rm -f /lib/systemd/system/anaconda.target.wants/*;
VOLUME [ "/sys/fs/cgroup" ]
CMD ["/usr/sbin/init"]

I strongly recommend to read the full description tab documentation on the hub. This will help you make it run correctly.
