| Deckard111 | hi everyone | 11:51 |
|---|---|---|
| Deckard111 | when I do : cloud-init query sys_info.uname | 11:51 |
| Deckard111 | I get | 11:52 |
| Deckard111 | ti | 11:52 |
| Deckard111 | [ | 11:52 |
| Deckard111 | "Linux", | 11:52 |
| Deckard111 | "0.limesurvey.host", | 11:52 |
| Deckard111 | "5.4.0-77-generic", | 11:52 |
| Deckard111 | "#86-Ubuntu SMP Thu Jun 17 02:35:03 UTC 2021", | 11:52 |
| Deckard111 | "x86_64", | 11:52 |
| Deckard111 | "x86_64" | 11:52 |
| Deckard111 | ] | 11:52 |
| Deckard111 | how would I access the 2nd string, only? | 11:52 |
| Deckard111 | I need it in cloud-config | 11:52 |
| falcojr | uname -n? | 12:31 |
| Deckard111 | found a way to read it and output it using jinja | 12:41 |
| Deckard111 | {{ sys_info.uname[1] }} | 12:41 |
| Deckard111 | however this key seems to change value at some point so i get back a different value | 12:42 |
| Deckard111 | so I am using {{ ds.meta_data.local_hostname }} | 12:42 |
| Deckard111 | which works | 12:42 |
| Deckard111 | falcojr uname-n would only work in the command section but I need to use it in the debconf module | 12:43 |
| Deckard111 | there is stil something fishy though | 13:09 |
| Deckard111 | I have another question: | 13:41 |
| Deckard111 | A cloud init config may sometimes include sensitive information. What is the best way to wipe all config data, once cloud-init is finished? | 13:42 |
| falcojr | the sensitive data gets stored in /run/cloud-init/instance-data-sensitive.json , but that file is only root readable and should get wiped on reboot | 13:45 |
| falcojr | and same with cloud-init query. If you're not running as root, it shouldn't return the sensitive data | 13:45 |
| Deckard111 | hm.. I can find copies of it in /var/lib/cloud/instances/12954850/user-data.txt | 13:47 |
| Deckard111 | is that provider-specific or also from cloud-init? | 13:49 |
| falcojr | there's no supported way to remove that data | 13:50 |
| Deckard111 | Could I just do it as a last command before reboot? Or would I saw off the branch I am sitting on? Let's try ;) | 14:05 |
| Deckard111 | ok, I can definitely say that cloud-init does not like that ;) | 14:35 |
