Setting umask

You are advised to set umask of the host and container to 027 or a larger value to improve file permission.

For example, to set umask to 027, perform the following operations:

1. Log in to the server as the root user and edit the /etc/profile file.

   1	vim /etc/profile

2. Add umask 027 to the end of the /etc/profile file, save the file, and exit.
3. Make the configuration take effect.

   1	source /etc/profile
