[cloud-init] installation

ahajnal · 2016-10-17 11:38:44

Hi All,

I tried to set up cloud-init on a fresh arch linux installation (4.7.6-1), following the description: https://wiki.archlinux.org/index.php/Cloud-init.
The end of the text was not clear for me (Systemd integration, what to do exactly here?), and when I tried to start and enable services
(e.g. systemctl start cloud-init-local.service, then systemctl enable cloud-init-local.service), I got errors: some python-related errors (missing site-packages),
systemd errors (dependences), and some missing commands (debconf-set-selections, dpkg, ...).

Some of them could be resolved by:
pacman -S python2-pip
pacman -S lsb-release
easy_install-2.7 cloud-init
add dependency to /usr/lib/systemd/system/cloud-config.target: After=... multi-user.target
add dependency to /usr/lib/systemd/system/cloud-init.target: After=multi-user.target

But yet during startup (in OpenNebula) I got errors (journalctl):
- Command: ['debconf-set-selections'] not found
- Command: ['dpkg', '--print-architecture'] not found
- in file "/usr/lib/python2.7/site-packages/cloudinit/util.py", line 1268, in load_file
pipe_in_out(ifh, ofh, chunk_cb=read_cb)
File "/usr/lib/python2.7/site-packages/cloudinit/util.py", line 1311, in pipe_in_out
data = in_fh.read(chunk_size)
IOError: [Errno 22] Invalid argument

I am not sure if I have to install dpkg AUR package or not, what to do with missing debconf-set-selections, or util.py error.
Some contextualization indeed worked (for example, the SSH key was injected correctly), I don't know yet about the rest (processing cloud-init file).

What should I do to properly install cloud-init? Anyone could do a flawless install?

Regards,
Akos

I think you have probably made matters worse by installing another copy of cloud-init via easy_install. Undo this, then tell us what errors you're running into. You did configure cloud-init to use the arch module, as described in the wiki, right?

Mod note: not an installation issue, moving to NC.

I forgot to set "distro" to "arch" in cloud.cfg.
I will report if I fail with the correct distro.
Sorry...

Maybe I do something very wrong but I still get error when trying to start cloud-init-local.service.
This is a fresh install of Arch Linux 4.7.6-1, then I installed the cloud-init package (pacman -S cloud-init),
edited /etc/cloud/cloud.cfg (setting default user to root), and didn't add any unverified_modules:.
(This is not a VM startup, but I simply tried to enable cloud-init-local service on the image before deploy...)

[root@arch ~]# systemctl start cloud-init-local.service
Job for cloud-init-local.service failed because the control process exited with error code.
See "systemctl status cloud-init-local.service" and "journalctl -xe" for details.
[root@arch ~]# cloud-init init --local

You're missing python{,2}-setuptools

that should be reported to the packager I guess

ahajnal · 2016-10-18 07:50:32

After separately installing python2-setuptools (pacman -S python2-setuptools), things have changed slightly.
(This dependency is listed in web https://www.archlinux.org/packages/comm … loud-init/ but not among in package dependencies (pacman -Si cloud-init).)

[root@arch ~]# pacman -S python2-setuptools

That one has been reported: https://bugs.archlinux.org/task/46909

Ok, then:
[root@arch ~]# pacman -S python2-requests
=>
pkg_resources.DistributionNotFound: The 'argparse' distribution was not found and is required by cloud-init

Which package contains 'argparse'? (argh is not ok.)

ahajnal · 2016-10-18 11:44:19

With the following I got ahead a bit:
[root@arch ~]# pacman -S python2-pip
[root@arch ~]# pip2 install argparse
[root@arch ~]# pip2 install oauthlib
[root@arch ~]# pip2 install jinja2

Now it seems there is some problem with the network settings. It is still a good sign.

I don't know what to do with this:

Changing line 79 in /usr/lib/python2.7/site-packages/cloudinit/distros/arch.py to:
'DNS': str(tuple(info.get('dns-nameservers'))).replace(',', '') if info.get('dns-nameservers') != None else None
allows to start and enable cloud init local (systemctl start cloud-init-local.service), however systemctl start cloud-init.service results in:
Failed to start cloud-init.service: Unit networking.service not found.
