Dmitry Tantsur d5b49bd498 Enable metadata cleaning by default 
We used to disable cleaning because only full disk cleaning was
available. Enable metadata cleaning by default and add an option
to enable full cleaning.

Testing Environment

Execute local testing

A simple scripts/test-bifrost.sh script can be utilized to install pre-requisite software packages, Ansible, and then execute the test-bifrost-create-vm.yaml and test-bifrost.yaml playbooks in order to provide a single step testing mechanism.

playbooks/test-bifrost-create-vm.yaml creates one or more VMs for testing and saves out a baremetal.json file which is used by playbooks/test-bifrost.yaml to execute the remaining roles. Two additional roles are invoked by this playbook which enables Ansible to connect to the new nodes by adding them to the inventory, and then logging into the remote machine via the user's ssh host key. Once that has successfully occurred, additional roles will unprovision the host(s) and delete them from ironic.

Command:

scripts/test-bifrost.sh

Note:

  • In order to cap requirements for installation, an upper_constraints_file setting is defined. This is consuming the UPPER_CONSTRAINTS_FILE env var by default, to properly integrate with CI systems, and will default to /opt/stack/requirements/upper-constraints.txt file if not present.

Manually test with Virtual Machines

Bifrost supports using virtual machines to emulate the hardware.

The VirtualBMC project is used as an IPMI proxy, so that the same ipmi hardware type can be used as for real hardware.

  1. Set testing to true in the playbooks/inventory/group_vars/target file.
  2. You may need to adjust the value for ssh_public_key_path.
  3. Execute the ansible-playbook -vvvv -i inventory/target test-bifrost-create-vm.yaml command to create a test virtual machine.
  4. Run the install step, as documented in /install/index, however adding -e testing=true to the Ansible command line.
  5. Set the environment variable of BIFROST_INVENTORY_SOURCE to the path to the JSON file, which by default has been written to /tmp/baremetal.json.
  6. Run the enrollment step <enroll>, using the JSON file you created in the previous step.
  7. Run the deployment step, as documented in deploy.
