Not able to access shared data volume

I have been trying to share data between my host and docker container. I am using this command to mount data volume:

sudo docker run -it -v /home/peeyush/Docker/docker/:/opt/test/:rw ubuntu /bin/bash

Now, when I run docker and try to access /opt/test/, it says I don't have the permission. But I have already specified permission as read-write and I am root. Here is the output:

root@d61b3bfe0aab:/# ls /opt/test/
ls: cannot open directory /opt/test/: Permission denied

Any idea what am I doing wrong here?

Update: Here is the output of ls -al /home/peeyush/Docker/docker:

[peeyush@localhost docker]$ ls -al /home/peeyush/Docker/docker/

Using a distro with SELinux? You can try turning it to passive (setenforce 0) or try a :Z/:z at the end of the -v command like (/home/peeyush/Docker/docker:/opt/test:Z)

Would be interested to see if it works without the trailing '/'s on the directory paths, as I have never used them and never had this issue.

sudo docker run -it -v /home/peeyush/Docker/docker:/opt/test ubuntu /bin/bash
