#REDIRECT [[Alpine Linux in a chroot]]
The Build Environment will be called [[#Create a build environment|BE]] from now on.<BR>
You will need a few Gigabytes to have enough pace for kernel compiling and storing all the binary packages and iso image.
= Create a build environment =
We are setting up our [[#Create a build environment|BE]] in chroot.<BR>
'''Note:''' The variables below:
* '''${build_dir}''' = You can name it whatever you like.
* '''${mirror}''' = Should be replaced with one of the available alpine-mirrors:
Lets start by geting the latest apk static binary:
wget ${mirror}/apk.static
chmod +x ./apk.static
We are setting up a basic chroot:
mkdir ${build_dir}
./apk.static --repo ${mirror}/packages/core --root $PWD/${build_dir} add --initdb build-base git abuildv
mkdir -p ./${build_dir}/proc
mount --bind /proc ./${build_dir}/proc
Lets setup our needed devices:
mknod -m 666 ./${build_dir}/dev/full c 1 7
mknod -m 777 ./${build_dir}/dev/null c 1 3
mknod -m 666 ./${build_dir}/dev/ptmx c 5 2
mknod -m 644 ./${build_dir}/dev/random c 1 8
mknod -m 644 ./${build_dir}/dev/urandom c 1 9
mknod -m 666 ./${build_dir}/dev/zero c 1 5
mknod -m 666 ./${build_dir}/dev/tty c 5 0
We need or dns servers and root dir:
cp /etc/resolv.conf ./${build_dir}/etc/
mkdir -p ./${build_dir}/root
We are setting up apk mirrors:
mkdir -p ./${build_dir}/etc/apk
echo "${mirror}/v1.9/packages/core" > ./${build_dir}/etc/apk/repositories
echo "${mirror}/v1.9/packages/extra" >> ./${build_dir}/etc/apk/repositories
At this point you should be able to enter your chroot:
chroot ./${build_dir} /bin/sh
