| Viktor87 | Hi everyone! Can I configure cloud-init not to run the second script in MIME multi-part userdata if the first script failed? | 19:41 |
|---|---|---|
| Viktor87 | ``` | 19:42 |
| Viktor87 | MIME-Version: 1.0 | 19:42 |
| Viktor87 | Content-Type: multipart/mixed; boundary="//" | 19:42 |
| Viktor87 | --// | 19:42 |
| Viktor87 | Content-Type: text/x-shellscript; charset="us-ascii" | 19:42 |
| Viktor87 | #!/usr/bin/env bash | 19:42 |
| Viktor87 | exit 1 | 19:42 |
| Viktor87 | --// | 19:42 |
| Viktor87 | Content-Type: text/x-shellscript; charset="us-ascii" | 19:42 |
| Viktor87 | #!/bin/bash | 19:42 |
| Viktor87 | exit 0 | 19:42 |
| Viktor87 | --//-- | 19:42 |
| Viktor87 | ``` | 19:42 |
| Viktor87 | In the cloud-init log I have: | 19:44 |
| Viktor87 | Jan 19 18:20:46 cloud-init[2692]: util.py[DEBUG]: Running command ['/var/lib/cloud/instance/scripts/part-001'] with allowed return codes [0] (shell=True, capture=False) | 19:44 |

| holmanb | Hey Viktor87 o/ | 19:44 |
| holmanb | I suppose you could do some sort of file-based IPC if you wanted | 19:46 |
| Viktor87 | I don't control the second script. The userdata is generated by karpenter and my script is inserted first. But I can control the mime header. | 19:47 |
| holmanb | ah | 19:47 |
| holmanb | hmm | 19:48 |
| Viktor87 | I guess they take my script and use "cloud-init devel" to generate the result userdata file. | 19:48 |
| Viktor87 | The problem is that the things they initialize in their script shouldn't be initialized if my script fails. | 19:49 |
| holmanb | Viktor87: you could try writing a custom handler to override the behavior of x-shellscript https://cloudinit.readthedocs.io/en/latest/explanation/format.html#part-handler | 19:50 |
| holmanb | this actually sounds like a pretty similar question to this recent bug report: https://github.com/canonical/cloud-init/issues/4572 | 19:51 |
| -ubottu:#cloud-init- Issue 4572 in canonical/cloud-init "Boothook not executing for cloud-init 'ubuntu/23.3.1-0ubuntu1_20.04.1'" [Open] | 19:51 | |
| holmanb | Viktor87: do you know if there is any connection between your issue and that bug report? | 19:52 |
| Viktor87 | No I don't think so | 19:56 |
| holmanb | thanks | 19:56 |
