Using "sudo su -" for privilege escalation

Hi there,

I’m trying to patch my hosts from the Katello interface, I don’t install the katello agent on them so I’m trying to use Foreman REX.

Problem:
I’m not able to run command as root with REX because the way my company elevates privileges is through the “sudo su” command.

Is there a way to customize REX behavior to use “sudo su” ?

It’s working nicely when I use the Katello Ansible Command, because I modified the /etc/foreman-proxy/ansible.cfg to add :

[privilege_escalation]
become_method = su
become_exe = “sudo su -”

But sadly patching machines via the interface can only be done with REX and the Job template Katello SSH … , not with Katello Ansible

Is there a way to modify rex to force it to use “sudo su -” ?

Expected outcome:
Working REX

Foreman and Proxy versions:
Foreman 1.24

Foreman and Proxy plugin versions:

Distribution and version:
CentOS Linux release 7.7.1908 (Core)

Thanks,

Regards

So apparently I can change from Katello SSH update to Katello Ansible Update, which is nice, by using the “administration => remote_execution_features” and modifying the templates accordingly, sadly the yum update is hanging :confused:

Soooo, Turns out the Katello Ansible Default templates for updating packages have a bug where the template is missing the yes flag for yum.

I filled an issue here :

In the mean time if like me you need it working, the fix is quite simple :
Edit the “Update Package - Katello Ansible Default fix” And go from :

%= render_template(‘Run Command - Ansible Default’, :command => “yum update #{input(‘package’)}”) %>

To

<%= render_template(‘Run Command - Ansible Default’, :command => “yum update -y #{input(‘package’)}”) %>

Thanks for the analysis, could you please also open a PR against https://github.com/Katello/katello/tree/master/app/views/foreman/job_templates

I’m happy you figured the template assignment, that’s exactly the purpose :slight_smile:

Hi there, sure I’ll do that, on the IRC they told me to also open one here : https://github.com/theforeman/community-templates
So I’ll do both with the same modification

I don’t think these templates live in the community-templates repo yet, however if you see missing -y there too in any of them, it should be fixed there as well. Thanks again for your help!
