Configure the Linux instance to mount this volume whenever the instance is started

tee
tee
is a command in command-line interpreters (shells) using standard streams which reads standard input and writes it to both standard output and one or more files, effectively duplicating its input.
-a
Appends the output to each file, rather than overwriting it.
fstab
The fstab
(or file systems table) file is a system configuration file commonly found at /etc/fstab
on Unix and Unix-like computer systems.
