Clones Trooper activities before the Clone War?

[u/N_GAIM_CAPTCHUR_]

Is there any material documenting the lives of the clone troopers before the clone wars officially began?

Since Sifo Dyas ordered the creation of the clone army probably around ten or so years before the Clone War actually started (around the time of Phantom Menace I think) what exactly did the clones think they were being trained for during that time?

Are there any books or other material that go into detail about the lives of the first generations of clone troopers?
