Hey Shivaram!
I don't have my laptop so just guessing, with the hope of unblocking you
before you get a better answer ;)
It could be an selinux denial? Container Linux never had selinux
configured meaningfully. You can check with "sestatus". Try adding
":z"
to your --volume flags, which might help until you can properly label the
files for selinux. Or maybe selinux is not enforcing and it's something
totally different.
Good luck!

Hello,
I have a simple service definition file - nginx-test.service and located
in user *core* home directory (/var/home/core) :
[Unit]
Description=This a basic Nginx service for a testing
After=docker.service
Requires=docker.service
[Install]
WantedBy=multi-user.target
[Service]
RestartSec=10
Restart=always
ExecStartPre=-/usr/bin/docker kill nginx-test
ExecStartPre=-/usr/bin/docker rm nginx-test
ExecStart=/usr/bin/docker run \
--name=nginx-test \
--network=host \
--volume=/var/home/core/nginx/config:/etc/nginx/conf \
--volume=/var/home/core/nginx/html:/usr/share/nginx/html \
nginx:1.17.2-alpine nginx -c /etc/nginx/conf/nginx.conf -g "daemon off;"
ExecStop=/usr/bin/docker stop nginx-test
This file is:
$ sudo cp nginx-test.service /etc/systemd/system/
$ sudo systemctl daemon-reload
$ sudo systemctl start nginx-test
$ pwd
/var/home/core
$ tree nginx
nginx
├── config
│ └── nginx.conf
└── html
└── index.html
This exact configuration works on my CoreOS AMI on AWS - which we use for
the last couple of years. But, it does not work with Fedora CoreOS on my
bare metal hardware. I even changed directory/file permissions on nginx
from core to root and still get the errors:
Aug 24 02:53:36 rhino docker[28805]: nginx-test

'exit-code'.
$ ls -l nginx/config/
total 4
-rw-r--r--. 1 root root 3735 Aug 24 01:08 nginx.conf
Is there a new way to make this work?
Thanks & Regards
