multipart user_data issues

[branzo]

Dear all,

I'm encountering an issue with the usage of a multipart user_data on a config-drive. I've assembled the file:

Content-Type: multipart/mixed; boundary="==BOUNDARY=="
MIME-Version: 1.0

==BOUNDARY==
MIME-Version: 1.0
Content-Type: text/cloud-config; charset="us-ascii"
Content-Disposition: attachment; filename="cloud-config"

set_timezone: Europe/Rome
users:
  - name: Administrator
    passwd: VerySecretPassword__?
  - name: myuser
    groups: Administrators
    passwd: AnotherVerySecretPassword?1
    inactive: false
  - name: otheruser
    groups: Administrators
    passwd: aScaryPassword_
    inactive: false

==BOUNDARY==
MIME-Version: 1.0
Content-Type: text/x-shellscript; charset="us-ascii"
Content-Disposition: attachment; filename="test.ps1"

echo "lol" | Out-File -Append -Path "C:\lol.log"

But when I boot an instance with this config drive attached, nothing gets done. By inspecting the logs I can see, as mentioned in #87, that the content is logged but then nothing seems to happen; here's the cloudbase-init.log.

Is multipart supported with openstack.configdrive / openstack.metadata or is it just supported w/NoCloud (as I can assume by having a look at #89)?

Hello, can you try with this exact example to see if you get a correct run?

Thanks.

I've got a run to the test config, and AFAICT it worked, here's the log.

Great to hear that, I think it is just a matter of reusing the template that works and add your own parts in the same manner. I think the issue was that your template did not conform with all the mime specs expected by the Python implementation used by cloudbase-init. Can you please try via an iterative approach to modify the one that works with your desired changes?

Something like:

Content-Type: multipart/mixed; boundary="===============1598784645116016685=="
MIME-Version: 1.0

--===============1598784645116016685==
Content-Type: text/cloud-config; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment; filename="cloud-config"

set_timezone: Europe/Rome
users:
  - name: Administrator
    passwd: VerySecretPassword__?
  - name: myuser
    groups: Administrators
    passwd: AnotherVerySecretPassword?1
    inactive: false
  - name: otheruser
    groups: Administrators
    passwd: aScaryPassword_
    inactive: false

The issue can be closed! :p
