Setting Immutable and Append Flags for Container Files and Directories

You can use standard Linux utilities— chattr and lsattr— to set extra flags for files and directories inside your Containers and to query their status, respectively. Currently, two of these extra flags—'append' and 'immutable'—are supported. For example, you can execute the following command to set the 'immutable' flag for the /root/MyFile file inside Container 101:

[root@ct101 root] chattr +i /root/MyFile

To check that the 'immutable' flag has been successfully set, use the following command:

[root@ct101 root] lsattr /root/MyFile

----i-------- /root/MyFile

Note: For detailed information on the chattr and lsattr utilities, see their manual pages.
