Hi all,
I did some testing of the new ALP project and here are some notes about
installing
and configuring it.
If you have more tips for the ALP then just write them here, thank you
in advance!
1. Download
===========
You can download the ALP images directly from
https://download.opensuse.org/repositories/SUSE:/ALP/images/
there are pre-built images for several platforms, choose the one which
best fits your use case.
In the iso/ subdirectory you can find bootable ISO images which can be
used to
install ALP in any system (even bare metal).
Note: As ALP is still in heavy development it is recommended to use a
virtual machine
for testing.
There are two types of images - with transactional system (read-only
file system with
snapshots) or non-transactional (classic, writable file system). Here it
depends what
you need to do and if you are already familiar with a transactional system.
If unsure then I'd suggest starting with the non-transactional images as
they are
more close to the traditional systems and are easier to use and manage.
2. Installation
===============
Uncompress the downloaded image with "unxz" and use the disk image in
your favorite
VM platform.
If you use the ISO image then just boot from it and then confirm
deploying the image
on the disk. Be careful, this rewrites ALL data on the target disk!
3. Configuration
================
The disk images use empty password for the root user (just press ENTER
when asked for
the password).
The ISO image installs a simple configuration tool [1] which runs at the
first boot
and can configure some basic things like locales or the root password.
4. Storage
==========
The disk images use virtual disk with size from 20 to 30GB (depends on
the type) so
there is quite a lot of free space for experimenting.
The ISO image installer creates just a 2GB root partition where about
1.2GB is used.
So there is not much space for experimenting, especially if you want to
run some
containers.
You can expand the root partition over the whole disk with these commands:
# resize the partition, the root FS is on /dev/sda4
# (note the space between the disk and the partition number!!)
growpart /dev/sda 4
# resize the filesystem
/usr/lib/systemd/systemd-growfs /
Btrfs can be resized online (while mounted) so you can see the result
immediately
and you do not need to reboot. You might check the resulting size with
"df -h /".
5. SSH Access
=============
By default the SSH service is enabled and running. However, the root
login is not
allowed by default.
There are two options:
1. Create a regular user:
# create the user
useradd <username>
# set the password
passwd <username>
Then use this user in the SSH connection. If you need to switch to root
then use "su" or "sudo" later.
2. Allow root Login
# create a config file
echo "PermitRootLogin yes" > /etc/ssh/sshd_config.d/root.conf
# restart the service
systemctl restart sshd
Then connect as root via SSH.
6. Software
===========
If you need to install some more packages then you can use zypper with the
pre-configured ALP repository.
If you need some package which is not present there then you might try
adding an OBS
repository which is built against openSUSE Tumbleweed. (ALP is based on
TW so the
packages should be compatible in the most cases.)
So if you want to try the latest YaST packages (especially the
"yast-in-container"
package) then use this repository [2].
HTH!

Great summary! Thanks Ladislav. IMHO, this guide deserves a wiki (or
similar) page.
