Use apt-get in chroot directory

Question

I am currently in need of using apt-get on a chroot directory. The setup is the following.

I have a chroot setup with schroot. This chroot environment needs to be stripped down as much as possible. Therefore I am planning to remove apt-get and commin from the chroot environment.

I know that Gentoo has the possibility to use portage on a different root directory. Is this possible to set a different root directory for apt.get to install software into my chroot directory?

Thanks in advance

You need debootstrap chroot.

Install packages on the host computer.

sudo apt-get install debootstrap
sudo apt-get install schroot

Create a configuration file for schroot.
Run debootstrap.
Check the chroot.
Now you can use whatever you want, including installation using

apt-get

The detailed instructions and more information can be found in the above link

Another useful link can be found here.

A simpler instructions:

Create a chroot environment into which you will install your packages:

debootstrap precise fakeInstallation

Replace "precise" with your Ubuntu version name, and "fakeInstallation" with directory you want to chroot.

Now you have created a fake installation in the fakeInstallation directory

chroot fakeInstallation

Now you can use apt-get install within the fakeInstallation directory

I dont want to use apt-get within the chroot environtment, but instead from my own and use the "global" apt-get to install stuff into the chroot without having apt-get installed inside the chroot – raddirad Jun 08 '15 at 07:32
@raddirad Any chance you found out how to do this? I want to do something similar. – Callum Rogers Feb 25 '21 at 22:52
