Allow Forge VM runs to disable the default synced folder - #963
The CentOS Jenkins Konflux gate boots its Stream 10 guests successfully, then fails mounting /vagrant using NFSv3 over UDP. The gate deploys and tests over SSH and does not need the shared directory. Currently, disabling it requires editing a Vagrantfile or installing a user-level override, as in jenkins-jobs#627.
What are the changes introduced in this pull request?
Add forge vms --synced-folder {enabled,disabled} and the FOREMANCTL_SYNCED_FOLDER environment variable. Sharing remains enabled by default.
Pass the setting through the VM playbook to Vagrant. An explicit CLI option overrides the environment; the option is not persisted.
Reject unsupported values in the Vagrantfile and expose the option in CLI help.
Add seven tests that exercise the real Forge CLI and Ansible playbook with a recording Vagrant stub, covering defaults, environment inheritance, CLI precedence, both up and provision, and invalid CLI values.
This is independent of the broader host-bootstrap work in #685/#757. Once available on the selected Foremanctl branch, CI can use this option instead of managing an overriding Vagrantfile.
Both guests should provision without exporting or mounting /vagrant. Alternatively, export FOREMANCTL_SYNCED_FOLDER=disabled before running Forge. An explicit --synced-folder enabled should override that environment setting.
Local validation completed:
pytest --confcutdir=tests/unit tests/unit/vms_test.py -q: 7 passed; no VMs allocated.
ruff check tests/unit/vms_test.py: passed.
ansible-lint --offline playbooks/vms/vms.yaml from development/: passed.
Real Vagrant 2.3.4 and 2.4.9 configuration loading: enabled by default, disabled when requested, invalid environment values rejected, across all built-in guests.
A live guest boot with this upstream change has not been run locally.
Checklist
Tests added/updated (if applicable)
Documentation updated (if applicable) — generated CLI help describes the option and default; no documentation files changed.
The VM command now accepts a synced-folder option and passes the selected setting to Vagrant. The /vagrant folder remains enabled by default and can be disabled. Unit tests cover defaults, overrides, propagation, and invalid options.
Changes: VM folder setting
Layer / File(s)
Summary
Select and pass the folder setting development/playbooks/vms/metadata.obsah.yaml, development/playbooks/vms/vms.yaml
The VM command adds a non-persistent --synced-folder option with enabled and disabled choices. The play sets FOREMANCTL_SYNCED_FOLDER from the option, the existing environment value, or enabled, in that order.
Apply and validate the setting Vagrantfile, tests/unit/vms_test.py
The Vagrantfile validates the setting and disables /vagrant when its value is disabled. Unit tests verify propagation to up and provision, inventory creation, defaults, overrides, and invalid-option rejection.

The change is mergeable with bounded follow-up: an invalid environment value can prevent VM cleanup, and changing the option does not update an already running guest. Both limitations have straightforward workarounds.

Full details: Linked Issues check
Explanation
Issue #962 requires an opt-in way to disable /vagrant, with sharing enabled by default, CLI and environment inputs, consistent Vagrant propagation, and Vagrantfile validation. metadata.obsah.yaml adds --synced-folder with enabled and disabled choices and persist: false. vms.yaml selects the CLI value, then FOREMANCTL_SYNCED_FOLDER, then enabled, and applies it to the play tasks. Vagrantfile consumes the environment value, rejects other values, and disables the synced folder only for disabled. The added tests cover defaults, environment inheritance, CLI precedence, both Vagrant actions, and invalid CLI input.

Cover the Vagrantfile synced-folder expression in a unit test.
The unit tests replace vagrant with a stub. The stub records its arguments and FOREMANCTL_SYNCED_FOLDER, but it never loads Vagrantfile. No test therefore exercises disabled: SYNCED_FOLDER == 'disabled' at Vagrantfile:20. A regression in that expression would leave the tests passing while --synced-folder disabled no longer disables the /vagrant share.
The current expression is correct. Vagrant receives a boolean disabled: value, so this is a test coverage gap, not a functional defect.
Add a test that loads Vagrantfile with a stubbed Vagrant.configure. The stub should record the synced_folder call and its disabled: value. Assert false for enabled and true for disabled. The Ruby stub can use a generic method_missing that returns itself and yields when a block is given. This covers the config.vm.define and provider blocks that the file also uses.
The sketch is illustrative. It does not cover every Ruby method in Vagrantfile. The test also depends on ruby being present where the unit suite runs. The sandbox has ruby at /usr/local/bin/ruby, but the CI runtime is not established.

Skip the synced-folder check for destroy, or forge vms stop fails.
The play sets FOREMANCTL_SYNCED_FOLDER from the inherited environment. The Vagrantfile aborts at load time on any value other than enabled or disabled. vagrant destroy also loads the Vagrantfile, so the abort blocks the stop command. Because the destroy task has no error handling, the play fails before any VM is destroyed. The inventory removal task in the same block is skipped.
Before this change, the inherited value was ignored, so the stop path succeeded with the same environment.
./forge vms stop --synced-folder enabled avoids the failure, because the play-level value uses vm_synced_folder first. Unsetting the variable also avoids it.

This keeps the validation for up, provision, and reload. For destroy, the invalid value reaches only the disabled: option, which evaluates to false and has no effect.

Document that vm_synced_folder takes effect when a VM boots, not on a running VM.
forge vms start runs vagrant up and vagrant provision on an existing VM. The inspected start path does not reapply synced folders to a running guest, so a changed value leaves the current /vagrant mount in place.
Do not add vagrant reload to this help text. A plain vagrant reload aborts unless ANSIBLE_COLLECTIONS_PATH is set, and it does not receive a value passed on the forge command line.
Suggested help-text change
vm_synced_folder:
parameter: --synced-folder
- help: Enable or disable /vagrant sharing. Defaults to FOREMANCTL_SYNCED_FOLDER or enabled.+ help: Enable or disable /vagrant sharing. Defaults to FOREMANCTL_SYNCED_FOLDER or enabled. Applies when a VM boots. A running VM keeps its current setting until it restarts.

Review comment at @Vagrantfile at line 20:
Update the help text for the vm_synced_folder parameter to clarify that the
setting applies when a VM boots and a running VM retains its current setting
until restarted. Do not add a vagrant reload instruction.

@ehelms do we ever need the synced folder?
I'd prefer to fully disable it.
I do not think so. This was added as part of initial import from Forklift most likely. Just drop it. If it comes back up that it needs to be used, we can discuss it then.

Why are you introducing these changes? (Problem description, related links)
Fixes #962.
The CentOS Jenkins Konflux gate boots its Stream 10 guests successfully, then fails mounting
/vagrantusing NFSv3 over UDP. The gate deploys and tests over SSH and does not need the shared directory. Currently, disabling it requires editing a Vagrantfile or installing a user-level override, as in jenkins-jobs#627.What are the changes introduced in this pull request?
forge vms --synced-folder {enabled,disabled}and theFOREMANCTL_SYNCED_FOLDERenvironment variable. Sharing remains enabled by default.upandprovision, and invalid CLI values.This is independent of the broader host-bootstrap work in #685/#757. Once available on the selected Foremanctl branch, CI can use this option instead of managing an overriding Vagrantfile.
How to test this pull request
On a prepared libvirt host:
Both guests should provision without exporting or mounting
/vagrant. Alternatively, exportFOREMANCTL_SYNCED_FOLDER=disabledbefore running Forge. An explicit--synced-folder enabledshould override that environment setting.Local validation completed:
pytest --confcutdir=tests/unit tests/unit/vms_test.py -q: 7 passed; no VMs allocated.ruff check tests/unit/vms_test.py: passed.ansible-lint --offline playbooks/vms/vms.yamlfromdevelopment/: passed.A live guest boot with this upstream change has not been run locally.
