## Build Alpine Linux packages
A simple way to setup a build environment is installing Alpine in a chroot.
In this way, you can set up an Alpine build environment in a chroot under a
different Linux distro.
There is a script that simplifies these steps with just two commands, and
can be found [here](https://github.com/alpinelinux/alpine-chroot-install).
Once the build environment is installed, you can setup the system to build
the packages by following [this document](https://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package).

If your distribution uses systemd:
# systemctl {start|stop|reload|status|enable|disable} icinga2
Or if your distribution uses openrc (like Alpine):
# rc-service icinga2
Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status}
Note: the openrc's init.d is not shipped by default.
A working init.d with openrc can be found here: (https://git.alpinelinux.org/cgit/aports/plain/community/icinga2/icinga2.initd). If you have customized some path, edit the file and adjust it according with your setup.
Those few steps can be followed:
# wget https://git.alpinelinux.org/cgit/aports/plain/community/icinga2/icinga2.initd
# mv icinga2.initd /etc/init.d/icinga2
# chmod +x /etc/init.d/icinga2
Icinga 2 reads a single configuration file which is used to specify all
configuration settings (global settings, hosts, services, etc.). The
configuration format is explained in detail in the [doc/](doc/) directory.
