<count> containers for the given service across the stack. If
<count> is an absolute value like
2, then that will be the total of
<count> containers across the application. If
<count> is a relative value like
[-3], then the current total count of containers across the application will be changed by
<count>. NOTE: the square brackets are required for relative count values.
