Subject: [ovirt-users] yaml cloud-init custom scripts
Hello,
I've been unsuccessfully trying to make work a custom yalm script with the
cloud-init option in 3.4.1.
All other native UI parameters are correctly configured (hostname...)
My goal is to change the keyboard layout:
write_files:
- content: |
# My new /etc/sysconfig/keyboard file
KEYTABLE="fr"
MODEL="pc105"
LAYOUT="fr"
KEYBOARDTYPE="pc"
path: /etc/sysconfig/keyboard
permissions: '0644'
I can't see what is wrong and there is nothing into cloud-init logs on the
guest (/var/log/clou-init-output.log).
isn't it in /var/log/cloud-init.log ?
Is it possible to see the whole yalm file generated by the engine somewhere?
the cloud init data is attached to the vm as a cd-rom
you can mount it locally and look inside the drive name is config-2 (look for
it with blkid)
for me on fedora 19 it always appear in /dev/sr1
First look at the mounted content as Omer suggested and take a look if the YAML
output as you expected.
You can also try to set the data that is written in the "custom script"
commit:

see if adding this content is working for your setup:
write_files:
- content: |
# some file content
path: /root/myfile
This sample was tested and worked under RHEL 6 and Fedora 19.
Please note that you need to add a tab/4 spaces as shown above.
What OS and what version of cloud-init you are using?
that's it, I finally managed to make it work after many an many tests,
that wasn't so trivial.
First I followed your advices and I successfully tested the sample
script you suggested without modify it. Then each time I attempted to
add a line to the same file, it wasn't executed anymore. I read the file
with cat -T /media/openstack/latest/user_data and then noticed that the
lines weren't uniformly formated : some were with tab and other ones
with 8 spaces.
Following "Please note that you need to add a tab/4 spaces as shown
above" I added tab on every lines related to content of the file, but it
didn't work.
I began again with only 8 spaces and then it ran.
Seems YAML to be very format sensitive and it is not clear enough when
begining this kind of job, so that I hope my leak will help many other ones.
I think the custom script field in the UI is not helpful because it is
impossible to insert a line, when doing a CR it leads to the end of
file, and it is a behaviour which easily leads to format error. It could
be a good idea to refuse validating OK if any tab is detected there.
Can I have your feeling about this?
