| | #REDIRECT [[Installing_Alpine_Linux_in_a_chroot]] |
| | |
| This document explains how to set up an Alpine build environment in a chroot under a "normal" Linux distro, such as Arch, Debian, Fedora, Gentoo, or Ubuntu. Once inside the chroot environment, you can build, debug and run alpine packages.
| |
| | |
| == Introduction ==
| |
| | |
| You need 80MB space for the tools + the space for the sources you are interested in. (You'd be able to compile all packages in less than 1 GB, given that you clean up sources after each package)
| |
| | |
| == Create a build environment ==
| |
| | |
| We are setting up our Build Environment 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:
| |
| | |
| {{Mirrors}}
| |
| | |
| <br> Lets start by geting the latest apk static binary:
| |
| | |
| wget ${mirror}/v1.9/apk.static
| |
| chmod +x ./apk.static
| |
| | |
| Verify you have apk-tools 2.0_rc1 or later:
| |
| ./apk.static --version
| |
| apk-tools 2.0_rc1
| |
| | |
| We are setting up a basic chroot:
| |
| | |
| mkdir ${build_dir}
| |
| sudo ./apk.static --repo ${mirror}/v1.9/packages/main -U --allow-untrusted --root ${build_dir} --initdb add alpine-base alpine-sdk
| |
| mkdir -p ./${build_dir}/proc
| |
| sudo mount --bind /proc ./${build_dir}/proc
| |
| | |
| Lets setup our needed devices:
| |
| | |
| sudo mknod -m 666 ./${build_dir}/dev/full c 1 7
| |
| sudo mknod -m 666 ./${build_dir}/dev/ptmx c 5 2
| |
| sudo mknod -m 644 ./${build_dir}/dev/random c 1 8
| |
| sudo mknod -m 644 ./${build_dir}/dev/urandom c 1 9
| |
| sudo mknod -m 666 ./${build_dir}/dev/zero c 1 5
| |
| sudo mknod -m 666 ./${build_dir}/dev/tty c 5 0
| |
| | |
| seems as /dev/null is wrong
| |
| sudo rm -f ./${build_dir}/dev/null && sudo mknod -m 666 ./${build_dir}/dev/null c 1 3
| |
| | |
| We need or dns servers and root dir:
| |
| | |
| sudo cp /etc/resolv.conf ./${build_dir}/etc/
| |
| mkdir -p ./${build_dir}/root
| |
| | |
| We are setting up apk mirrors:
| |
| | |
| sudo mkdir -p ./${build_dir}/etc/apk
| |
| sudo su
| |
| echo "${mirror}/v1.9/packages/main" > ./${build_dir}/etc/apk/repositories
| |
| exit
| |
| | |
| At this point you should be able to enter your chroot:
| |
| | |
| sudo chroot ./${build_dir} /bin/sh -l
| |
| | |
| If you are using Alpine as a Native build system you will have to make sure that chroot can run chmod. Add following to /etc/sysctl.conf
| |
| kernel.grsecurity.chroot_deny_chmod = 0
| |
| Then run the following command
| |
| sysctl -p
| |
| | |
| | |
| Now you can move on to [[Creating_an_Alpine_package|creating packages for Alpine.]]
