Description of problem:

By default if we have a hostname set something like this i.e. SATELLITE.example.com , Then installer will immediately fail to execute due to the check in place i.e. https://github.com/theforeman/foreman-installer/blob/develop/checks/hostname.rb#L56

# satellite-installer
2023-04-05 22:12:46 [NOTICE] [root] Loading installer configuration. This will take some time.

~~

When a host entry is created in satellite , Even that is also downcase'ed via https://github.com/theforeman/foreman/blob/develop/app/models/host/base.rb#L126-L142 .

But now, Lets say when i fix the OS hostname of said satellite instance, and pass some arguments with satellite-installer having values like SATELLITE.example.com, those are somehow accepted and is not downcased at all ( resulting in weird issues ).

If we look into 1 and 2, we will see we directly use $facts['networking']['fqdn'] but then in one or two places we use $lower_fqdn which is downcase($facts['networking']['fqdn'])

In my opinion, we should use $lower_fqdn almost everywhere, where we need to use the FQDN.

Version-Release number of selected component (if applicable):

Satellite 6.10/6.11/6.12/6.13 

( Reproducer created on 6.11.5 )


How reproducible:

Always and easily 

Steps to Reproduce and Results:

1. On a RHEL 8 box, enable required repos, modules and install the satellite rpm and it's dependencies.
2. Ensure that the OS has a valid hostname set i.e. satellite.example.com
3. Run the satellite-installer in the following way

# satellite-installer --scenario satellite --verbose \
--foreman-initial-organization "RedHat" \
--foreman-initial-location "GSS" \
--foreman-initial-admin-username admin \
--foreman-initial-admin-password RedHat1! \
--enable-foreman-plugin-puppet \
--enable-foreman-cli-puppet \
--foreman-proxy-puppet true \
--foreman-proxy-puppetca true \
--foreman-proxy-content-puppet true \
--enable-puppet \
--puppet-server true \
--puppet-server-foreman-ssl-ca /etc/pki/katello/puppet/puppet_client_ca.crt \
--puppet-server-foreman-ssl-cert /etc/pki/katello/puppet/puppet_client.crt \
--puppet-server-foreman-ssl-key /etc/pki/katello/puppet/puppet_client.key \
--foreman-proxy-puppet-url https://SATELLITE.example.com:8140 \
--foreman-proxy-template-url http://SATELLITE.example.com:8000 \
--foreman-proxy-registered-name SATELLITE.example.com \
--foreman-servername SATELLITE.example.com \
--certs-node-fqdn SATELLITE.example.com \
--certs-ca-common-name SATELLITE.example.com


4. It will fail with an error like this i.e.

2023-03-30 14:32:59 [ERROR ] [configure] Host SATELLITE.example.com does not exist in Foreman at https://satellite.example.com/
2023-03-30 14:32:59 [ERROR ] [configure] /Stage[main]/Foreman_proxy::Register/Foreman_smartproxy_host[foreman-proxy-SATELLITE.example.com]/ensure: change from 'absent' to 'present' failed: Host SATELLITE.example.com does not exist in Foreman at https://satellite.example.com/
2023-03-30 14:36:32 [NOTICE] [configure] System configuration has finished.


Because, The smart-proxy entry is created with malformed FQDN i.e.

# echo "select * from smart_proxies;" | su - postgres -c "psql -x foreman"
-[ RECORD 1 ]---+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
id              | 1

expired_logs    | 0
puppet_path     | 
download_policy | on_demand

But the entry of satellite itself as a host, has been created by puppet facts with expected FQDN :

# echo "select id,name,certname,type,lookup_value_matcher from hosts where name ilike '%SATELLITE%';" | su - postgres -c "psql -x foreman"
-[ RECORD 1 ]--------+----------------------------------------
id                   | 1
name                 | satellite.example.com
certname             | satellite.example.com
type                 | Host::Managed
lookup_value_matcher | fqdn=satellite.example.com


5. Now, if we want to fix it, Just update the name of the smart-proxy from SATELLITE.example.com to satellite.example.com and then run "satellite-installer" which will finish successfully and gives us an assumption that evcerything is fine.

6. But pulp is messed up:

# cat /etc/pulp/settings.py | grep -i satellite
CONTENT_HOST = "SATELLITE.example.com"
CONTENT_ORIGIN = "https://SATELLITE.example.com"
ANSIBLE_API_HOSTNAME = "SATELLITE.example.com"
ANSIBLE_CONTENT_HOSTNAME = "https://SATELLITE.example.com/pulp/content"

And it cannot do anything right now due to how we got the installer completed and how pulp knows about the malformed FQDN:

# echo "Katello::Pulp3::Api::ContentGuard.new(SmartProxy.pulp_primary).refresh" | foreman-rake console
Loading production environment (Rails 6.0.6)
Switch to inspect mode.
Katello::Pulp3::Api::ContentGuard.new(SmartProxy.pulp_primary).refresh
Traceback (most recent call last):

        3: from (irb):1

Response body: {"detail":"Authentication credentials were not provided."}

And the same error will continue to affect any new pulp actions unless the issue is properly fixed. 


Additional info:

The only way to fix this scenarios is to re-use the exact same set of installer params with correct FQDN i.e. all in lowercase 


satellite-installer --scenario satellite --verbose \
--foreman-proxy-puppet-url https://satellite.example.com:8140 \
--foreman-proxy-template-url http://satellite.example.com:8000 \
--foreman-proxy-registered-name satellite.example.com \
--foreman-servername satellite.example.com \
--certs-node-fqdn satellite.example.com \
--certs-ca-common-name satellite.example.com
