what is your host2 meant to be? the docker image itself or the host?
from the docker point of view, 127.0.0.1 is the docker itself.
if you want to access the host itself, then you need to use
host.docker.internal
if you really want to access the dockers onw apache, then you have to
configure that it listens to localhost/127.0.0.1.
Configure docker or apache are generally thought as off topic as it's
nothing to do with PHP.
