vm_created subscription not working

[captainwasabi]

or, at least, I am not seeing any output in the /tmp/sub_output.txt file

I an using the sample script. I put it in /etc and gave the full path in the configuration.

running the script from the command line gives the output that I would expect.

Hi!

Please show configuration file and vmango log, you can get it with journalctl -u vmango

Log looks like everything is okay, maybe script prints to stderr? Try to use sample script or redirect all output to log file with &>:

script = "/etc/ssg-subscribe-script.sh $VMANGO_VM_ID $VMANGO_VM_VOLUME_0_PATH &> /tmp/sub_output.txt"

[captainwasabi]

I am using the sample script (I just used a different name).

Changing to &> didn't change anything.

Setting selinux to Permissive didn't help either

I tried echoing straight to the log file from inside the script, doesn't work from vmango, if I run the script by hand it does work.

[subuk]

Ah, vmango uses private tmp: https://github.com/subuk/vmango/blob/master/vmango.service#L12 So look for directory named /tmp/system-private-XXX-vmango.service-XXX/tmp/, file will be there.

You can override unit configuration if necessary https://unix.stackexchange.com/questions/398540/how-to-override-systemd-unit-file-settings

[captainwasabi]

sorry, it took me a bit to circle back around to look at this. Logfile was there.

virt-customize won't run on the image (I think because the image is owned by qemu with perms 600 and vmango is running as vmango)

However, I think I can do what I need to do with Userdata cloud-config

[subuk]

Hooks run from vmango user, if you allow this user to use sudo without password and run virt-customize with sudo, it will work, but yes, cloud-init is a more simple way to customize image.
