Run squid proxy service in a systemd enable centos 7 container

I am unable to start squid service in a systemd enabled centos 7 container. I am able to install the squid package. this is what I got before starting the service :

[root@c65bf5111b85 /]# systemctl status squid
● squid.service - Squid caching proxy
   Loaded: loaded (/usr/lib/systemd/system/squid.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

and then when I do the systemctl start squid this is what I got :

[root@c65bf5111b85 /]# systemctl status squid
● squid.service - Squid caching proxy
   Loaded: loaded (/usr/lib/systemd/system/squid.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

Apr 28 23:46:23 c65bf5111b85 squid: Squid Parent: (squid-1) process 280 exited with status 0
Apr 28 23:46:23 c65bf5111b85 squid: squid: No running copy
[root@c65bf5111b85 /]#

I am expecting the service to start as I was able to install and start httpd, nginx, mariadb services.
