-# The ADD instruction will always download the file and the cache will be invalidated if the checksum of the file no longer matches
-# On the other hand, the RUN instruction will not invalidate the cache unless its text changes. 
-# So if the remote file is updated, you won't get it. Docker will use the cached layer.
-# In our case, the gnat-2021-20210519-x86_64-linux-bin will not change. So, it is preferable to ADD
