RE: Centos 7.9 - cloud-init password reset?

[Yordan Kostov]

Hey Andrija and 조대형,

        Here is a script a threw 
https://github.com/dredknight/cloud_scripts/blob/master/CloudStack-Xen/centos7_prep.bash
        It implements the following features:
        - some OS prep + install some packets
        - install cloud-init related packets
        
        Cloud-init features:
        - datasources -  sets as ConfigDrive and CloudStack as default 
datasources
        - password + reset      
                - makes password module run on every boot instead of once per 
instance - - cloud.cfg
                - assigns user with name cloud-user to be integrated with 
Cloudstack (initial password set + reset) - 80_root.cfg
        - autoextend root partition (only) upon resize from Cloudstack GUI
                - uses growpart to rewrite MBR tables - 50_growpartion.cfg
                - adds additional commands to extend PVS, VGS and LVS after 
that - 51_extend_volume.cfg

Script is in a bit of raw shape but it works.
Currently I am doing similar script for Ubuntu. 

Thanks for the heads up Andrija, I have to do a documentation for the team 
anyway so I better contribute to what is already existing instead of doing it 
from scratch 😊.

Btw if anyone has some tips on the cloud-init feature for the SSH keys I would 
like to add that too to the bundle.

Best regards,
Jordan

Hi, Jordan.

I am the one who is testing the same solution and need a solution.
Can you share the knowledge?

Thanks in advance.

Thanks,

Would it be nice if you could update the ACS documentation on the 
password-reset script, to very briefly explain how the same can be achieved 
with cloud-init, and what to look-for (i.e. issues you had etc)

This would help the product and other users which might have the same issue.

Thanks,
