Add cloud-connector as a native foremanctl feature

[jeremylenz]

Summary

• Re-implements the upstream satellite_operations.cloud_connector role natively in foremanctl (SAT-45966 / SAT-44641)
• New cloud-connector feature gated behind --add-feature cloud-connector, with rh-cloud dependency
• Installs rhc and yggdrasil-worker-forwarder, configures the worker, starts rhcd, sets rhc_instance_id via the Foreman API, and announces to Sources
• Works with both foremanctl deploy and forge deploy-dev (dev uses separate admin credentials)
• Early pre-checks validate package availability and mutual exclusion with the iop feature
• Adds Foreman CA to system trust store so the worker binary can verify Foreman's certificate
• Optional --cloud-connector-http-proxy flag for environments without direct internet access

Companion PR: theforeman/foreman_rh_cloud#1214 (adds the announce_to_sources API endpoint)

Test plan

• foremanctl deploy --add-feature cloud-connector completes successfully
• foremanctl features --list-enabled includes cloud-connector
• systemctl status rhcd shows active/running
• /etc/rhc/workers/foreman_rh_cloud.toml has correct content
• hammer settings info --name rhc_instance_id shows the consumer cert CN
• Second foremanctl deploy is idempotent
• forge deploy-dev --add-feature cloud-connector completes successfully
• Enabling both cloud-connector and iop fails early with a clear error
• Deploying without yggdrasil-worker-forwarder repo enabled fails early with a clear error

We should be able to enforce this at the parameter level that these two features cannot co-exist.

[jeremylenz]

What exactly do you mean by parameter? I attemped to solve this with a new PR which I am now realizing I hadn't raised yet, stand by..

[jeremylenz]

#570

[jeremylenz]

Is #570 what you had in mind?

[ehelms]

Is this sufficient? What if the system is registered to somewhere else for example? What if the system has a consumer cert but it's stale or cannot reach console.redhat.com ?

[jeremylenz]

All of those things will cause it to break later, either during deploy or after. But this is the same thing the original role does. (I actually added this check so that it will fail earlier than it would otherwise.)

[ehelms]

Would a subscription-manager status tell us more?

[jeremylenz]

subscription-manager status gives us this:

# subscription-manager status
+-------------------------------------------+
   System Status Details
+-------------------------------------------+
Overall Status: Registered
Content Access Mode is set to Simple Content Access. This host has access to content, regardless of subscription status.

subscription-manager identity gives us the actual consumer uuid:

# subscription-manager identity
system identity: cf46f013-6455-4ceb-913e-b1af651f098b
name: ip-10-0-198-13.rhos-01.prod.psi.rdu2.redhat.com
org name: 11949999
org ID: 11949999

But that command does make an API call.

[ehelms]

Is this how we do it today? This is an anti-pattern we have been trying to avoid.

[jeremylenz]

foreman-installer does the same thing via puppet-certs:

• templates/rhsm-katello-reconfigure.erb — copies to /etc/pki/ca-trust/source/anchors/ and runs update-ca-trust
• manifests/katello.pp — uses trusted_ca::ca to do the same

We need it here because yggdrasil-worker-forwarder is a Go binary that uses the OS trust store — no way to pass it a CA path. That said, we could move this into the certificates role so it's done once globally instead of per-feature. Would that be cleaner?

[jeremylenz]

I was apprehensive about this too. I figured we can change it later..
Claude reply above

[ehelms]

• templates/rhsm-katello-reconfigure.erb — copies to /etc/pki/ca-trust/source/anchors/ and runs update-ca-trust
• manifests/katello.pp — uses trusted_ca::ca to do the same

These are both 404s because they were moved quite a bit ago. I think we need to consider udpating yggdrasil-worker-forwarder vs. starting this trend of relying on the system store. Let's phone a friend for another opinion. @evgeni ☎️

[jeremylenz]

We need to update it anyway to use DBUS (so it can run on RHEL 10), so we can probably just tack that change on there.

[jeremylenz]

https://github.com/theforeman/yggdrasil-worker-forwarder doesn't seem to use Github Issues, so I will create an internal Jira for that.

[jeremylenz]

I updated the description of https://redhat.atlassian.net/browse/SAT-27307. However, ideally I would like this PR to be merged and use the "incorrect" approach temporarily, to move things forward,.

[ehelms]

This is the part we still need to work out how to properly handle, that is, the authentication.

[jeremylenz]

As I see it our options are
1 - Keep things as they are here, feeding admin/changeme to rhc - Not acceptable because the admin password ends up in the worker config.toml.
2 - Create a service user with limited permissions - Doable in the existing PRs here and in foreman_rh_cloud.
3 - Create a service user + personal access token and use that, same as the previous architecture - FAM doesn't have a module for personal access tokens, so this would be a fair bit of work

I think Option 2 seems promising and am pushing that update now.

[jeremylenz]

Pushed updates addressing review feedback (1bfe640):

• Handler: switched from ansible.builtin.service to ansible.builtin.systemd_service since we use daemon_reload
• Workers directory: removed the task — confirmed rhc package on EL9 creates /etc/rhc/workers/
• Settings API: replaced raw uri calls with theforeman.foreman.setting module for rhc_instance_id and allow_auto_inventory_upload
• Lint fix: added noqa: no-static-secrets on the defaults password (same pattern as foreman_development)

rebased & fixed conflicts

[qcjames53]

I'm not enough in the loop to give this a full review but had a few comments that might be helpful. Consider this 80% good points 20% ass-talking. Here's what I was able to test directly:

• The iop conflict and missing consumer cert checks both work on the positive and negative cases (used manual subscription manager commands for the latter).
• The yggdrasil-worker-forwarder check works in the negative (was unable to figure out package install on centos9).
• The cloud connector role works.

Beyond these tests, I have questions about the whole approach of cloud connector even after reading the planning docs and such.

1. How are we splitting RHEL and Centos 9 deploys? I think the differentiation needs to be clearer since (best I can tell) yggdrasil-worker-forwarder is RHEL only. If the packaged container images are centos9 and the rpms needed for cloud connector are RHEL-only, that seems like a big problem to me!
2. deploy-dev needs to work with cloud connector. At minimum a procedure but ideally out of the box. I think we really need a procedure for setting up a centos9 deploy-dev environment to build/test cloud connector. If that's not possible, then we need a good procedure for setting up a RHEL environment as deploy-dev.
3. If it's possible to pass in subscription manager credentials safely, I would greatly prefer if we could deploy an environment with cloud connector immediately instead of requiring manual registration for the quadlet VM, THEN adding the feature. I understand this won't be an issue for customers but this would be HUGE for testing purposes.

I have to gracefully bow out of reviewing this for a few reasons: capacity + artemis stuff + this baby could come any day! Sorry to not complete testing but I put in an honest effort.

[qcjames53]

yggdrasil-worker-forwarder - Is this available in centos9? Where is it shipped? I know it won't be a problem for shipping pre-built images but for dev environments and such we should really document a pathway for getting this installed.

[jeremylenz]

I checked and it's in https://yum.theforeman.org/plugins/3.19/el9/x86_64/

[qcjames53]

Same as above but opposite. Idempotency?

[jeremylenz]

This is correct — changed_when: false means "this command never changes anything," which is right for a read-only openssl x509 call. Standard Ansible pattern for info-gathering tasks.

[jeremylenz]

I'll respond with thoughts off the top of my head :)

1. How are we splitting RHEL and Centos 9 deploys? I think the differentiation needs to be clearer since (best I can tell) yggdrasil-worker-forwarder is RHEL only. If the packaged container images are centos9 and the rpms needed for cloud connector are RHEL-only, that seems like a big problem to me!

In order for cloud connector to work you need available on your base system:

1. ansible-runner command - Downstream, from the Satellite repo, e.g. satellite-6.19-for-rhel-9-x86_64-rpms. Upstream, from the Foreman Plugins repo, e.g. https://yum.theforeman.org/plugins/3.19/el9/x86_64/
2. yggdrasil-worker-forwarder - Downstream, from the Satellite repo. Upstream, from the Foreman Plugins repo, e.g. https://yum.theforeman.org/plugins/3.19/el9/x86_64/
3. rhc - from AppStream (CentOS or RHEL)

In the previous architecture, these weren't even listed as prerequisites, even in upstream docs. Downstream, you'd already have all of these since the Satellite system must be registered and have those repos enabled. But upstream, anything can happen. It seems this is a documentation gap. cc @Lennonka

2. deploy-dev needs to work with cloud connector. At minimum a procedure but ideally out of the box. I think we really need a procedure for setting up a centos9 deploy-dev environment to build/test cloud connector. If that's not possible, then we need a good procedure for setting up a RHEL environment as deploy-dev.

I was testing with deploy-dev on RHEL (with --target-host localhost). I think it works fine, as long as you have the repos available that I mentioned above.

🔍 Testing Methodology

Environment: Development mode using forge deploy-dev with Rails source code
Test Scope:

• Cloud connector deployment
• Service user authentication
• API endpoint functionality
• Worker configuration

🔗 Related/Dependent PRs

Foreman RH Cloud Plugin

• PR: Repurpose CloudConnectorAnnounceTask for daily Sources registration foreman_rh_cloud#1214
• Purpose: Cloud connector service user and role support
• Status: Pending
• Dependency: Required for cloud connector service user authentication functionality

Foremanctl Branch Preservation

• PR: Add --preserve-plugin-branches flag to deploy-dev #568
• Purpose: Preserve plugin branches during development deployment
• Status: Pending
• Dependency: Needed for --preserve-plugin-branches flag used in testing

Note: These PRs should be merged before or alongside this cloud connector feature PR.

✅ What Works

1. Cloud Connector Deployment

• ✓ Cloud connector role created successfully
• ✓ Required packages present (rhc, yggdrasil-worker-forwarder) - installed as prerequisite
• ✓ Worker config file created: /etc/rhc/workers/foreman_rh_cloud.toml
• ✓ rhcd service running and enabled

Note: The cloud connector role does not install packages - it assumes rhc and yggdrasil-worker-forwarder are already present (installed manually or by prerequisite roles).

2. Service User Authentication

Created service user cloud_connector_user with proper credentials:

User ID: 5
Role: Cloud Connector
Auth Source: Internal
Last Login: Successfully authenticated via API

3. API Endpoint Verification

Manual test of /api/v2/rh_cloud/cloud_request endpoint:

Request:

curl -u cloud_connector_user:$PASSWORD \
  -X POST \
  http://localhost:3000/api/v2/rh_cloud/cloud_request \
  -H 'Content-Type: application/json' \
  -d '{"directive":"foreman_rh_cloud", ...}'

Result:

✓ Authenticated user cloud_connector_user against INTERNAL authentication source
✓ Authorized user cloud_connector_user(cloud_connector_user)
✓ Request processed (playbook URL validation occurred as expected)

4. Configuration Validation

• ✓ rhc_instance_id setting configured: 5fc35187-ee43-48a8-b61a-01c0153d0562
• ✓ Worker URL correct: http://localhost:3000/api/v2/rh_cloud/cloud_request
• ✓ Credentials properly stored in worker config

🔧 Required Code Changes

Found 3 necessary changes for development environment support:

Change 1: Development URL Configuration

File: development/playbooks/deploy-dev/deploy-dev.yaml

Issue: Development uses Rails dev server on port 3000, not containerized Foreman

Fix:

vars:
  cloud_connector_url: "http://localhost:3000"
  cloud_connector_admin_user: "{{ foreman_development_admin_user }}"
  cloud_connector_admin_password: "{{ foreman_development_admin_password }}"

Why: Points worker to the correct development Rails server endpoint

---

Change 2: Disable Certificate Validation for HTTP

File: src/roles/cloud_connector/tasks/main.yaml

Issue: Development uses HTTP (no SSL), certificate validation fails

Fix:

- name: Create cloud connector service user
  theforeman.foreman.user:
    # ... existing parameters ...
    validate_certs: false  # <-- Add this

Why: HTTP connections don't have valid certificates in development

---

Change 3: Make CA Certificate Path Optional

File: src/roles/cloud_connector/tasks/main.yaml

Issue: No CA certificate exists for HTTP connections, undefined variable error

Fix:

- name: Create cloud connector service user
  theforeman.foreman.user:
    # ... existing parameters ...
    ca_path: "{{ foreman_ca_certificate | default(omit) }}"  # <-- Change this

Why: Prevents Ansible error when foreman_ca_certificate is undefined (HTTP mode)

---

⚠️ Known Limitations

Automated pytest Suite Skipped

Issue: All 6 cloud connector tests were skipped:

tests/cloud_connector_test.py::test_rhc_package_installed SKIPPED
tests/cloud_connector_test.py::test_yggdrasil_worker_forwarder_package_installed SKIPPED
tests/cloud_connector_test.py::test_workers_directory_exists SKIPPED
tests/cloud_connector_test.py::test_worker_config_exists SKIPPED
tests/cloud_connector_test.py::test_worker_script_exists SKIPPED
tests/cloud_connector_test.py::test_rhcd_service_running SKIPPED

Root Cause:

• pytest hardcoded to check ./foremanctl features (production state)
• Development uses ./forge deploy-dev (separate state)
• Feature flags from --add-feature are temporary, not persisted

Impact:

• ❌ Automated test suite cannot verify development deployments
• ✅ Manual verification confirms all test criteria pass

Re: Change 1 - cloud_connector_url defaults to foreman_url which is https://{{ fqdn }},
and httpd proxies to the Rails server. The HTTPS URL through httpd works fine in dev — we tested it. Using http://localhost:3000 directly would bypass httpd and also break the ca_path on
all the FAM module calls. The worker TOML would also have an HTTP URL, which means the runtime cloud requests would go over unencrypted HTTP.

Change 2 is not necessary unless I were to do Change 1, which I think is not needed for the reason above.

Updating now with Change 3.

[jeremylenz]

Btw, Our role does install the packages — line 2-7 of tasks/main.yaml:

  - name: Install rhc and yggdrasil-worker-forwarder
    ansible.builtin.package:
      name:
        - rhc
        - yggdrasil-worker-forwarder
