Ironic in OC - Adding rootpwd to pxe_append_params and restarting ironic_conductor fails

Environment:
python2-ironic-neutron-agent-1.0.0-1.el7ost.noarch
puppet-ironic-12.4.0-5.el7ost.noarch
openstack-ironic-api-10.1.8-2.el7ost.noarch
openstack-ironic-inspector-7.2.3-1.el7ost.noarch
python2-ironicclient-2.2.2-1.el7ost.noarch
python-ironic-lib-2.12.2-1.el7ost.noarch
python-ironic-inspector-client-3.1.2-1.el7ost.noarch
instack-undercloud-8.4.7-2.el7ost.noarch
openstack-ironic-common-10.1.8-2.el7ost.noarch
openstack-ironic-staging-drivers-0.9.1-1.el7ost.noarch
openstack-ironic-conductor-10.1.8-2.el7ost.noarch


Steps to reproduce:

1. Deploy OC with BMaaS.
2. Edit /var/lib/config-data/puppet-generated/ironic/etc/ironic/ironic.conf and place the following line under [pxe] section:
pxe_append_params = rootpwd="$1$/M4TEgtJ$<string>" selinux=0

3. Try to stop/start ironic_conductor.

Result:

Comment 1 Bob Fournier 2019-04-15 20:27:34 UTC

Sasha - are you trying to add a password to IPA?  Can you try this procedure which involves unpacking the image - https://mojo.redhat.com/people/dsorrent/blog/2016/08/13/inspecting-introspection.

I don't believe setting pxe_append_params with a new password will work.

Comment 2 Alexander Chuzhoy 2019-04-15 20:59:46 UTC

The procedure in comment#1  worked for me.

If the steps I tried in comment#0 shouldn't work - lets convert this into a doc bug for documenting the right way to set the password for ramdisk image. It's very useful for debugging.

Comment 4 Dmitry Tantsur 2019-04-16 09:34:55 UTC

Let's document setting SSH keys instead? The issue is in the $ symbol, which oslo.config interprets.

Sasha, could you try doubling all $$ symbols, i.e. 

 pxe_append_params = rootpwd="$$1$$/M4TEgtJ$$<string>" selinux=0

? According to https://docs.openstack.org/oslo.config/latest/reference/configuration-files.html#option-value-interpolation that's the way interpolation is avoided.

Note that it's a good idea to keep the default content of pxe_append_params, i.e. 

 pxe_append_params = nofb nomodeset vga=normal rootpwd="$$1$$/M4TEgtJ$$<string>" selinux=0

Comment 5 Alexander Chuzhoy 2019-04-16 16:32:00 UTC

Using double '$' worked. Below is an example with "redhat" as a password:
pxe_append_params = nofb nomodeset vga=normal rootpwd="$$1$$YTeWzzp7$$HVs0zv7yhLRA6.egigc9.1"

We could/should document both ways.

Comment 7 Andreas Karis 2020-02-27 15:07:30 UTC

*** Bug 1807871 has been marked as a duplicate of this bug. ***

Comment 8 Andreas Karis 2020-02-27 15:07:41 UTC

Hi docs team, please modify the ironic overcloud guide and incorporate this KCS into it:
https://access.redhat.com/solutions/4860841

Thanks,

Andreas

Comment 11 Steve Baker 2021-10-26 19:57:29 UTC

I'm going to close this on the basis that the KCS exists for those who need it, and putting it in the documentation will imply that it is a supported action, which we're not comfortable with encouraging.
