I see that the read command stores input entered only on the console

$ read a

$ echo $a
foo
But when I don't enter input on the console by keyboard, but pipe it
into the standard input of read, I am unable to store the input into
the variable.
$ echo bar | read a
$ echo $a
foo
As others pointed out, the variable a that is read is in another shell.
If you want to do something like this, you need to turn it around:
a=$(echo bar)
