Ben Nemec 9a29b4d052 Add logging to capabilities filter
The capabilities filter gets incorrectly blamed for a lot of
deployment failures because on a retry of a node deployment the
filter has to fail because there is only one node that can match
when using predictable placement.  However, we don't have any
logging to help determine why the filter fails.  This adds logging
to explain why nodes fell through, which will hopefully help with
debugging these problems.

tripleo-common

A common library for TripleO workflows.

Action Development

When developing new actions, you will checkout a copy of tripleo-common to an undercloud machine and add actions as needed. To test the actions they need to be installed and selected services need to be restarted. Use the following code to accomplish these tasks. :

sudo rm -Rf /usr/lib/python2.7/site-packages/tripleo_common*
sudo python setup.py install
sudo cp /usr/share/tripleo-common/sudoers /etc/sudoers.d/tripleo-common
sudo systemctl restart openstack-mistral-executor
sudo systemctl restart openstack-mistral-engine
# this loads the actions via entrypoints
sudo mistral-db-manage populate
# make sure the new actions got loaded
mistral action-list | grep tripleo

Validations

Prerequisites

If you haven't installed the undercloud with the enable_validations set to true, you will have to prepare your undercloud to run the validations:

$ sudo pip install git+https://git.openstack.org/openstack/tripleo-validations
$ sudo yum install ansible
$ sudo useradd validations

Finally you need to generate an SSH keypair for the validation user and copy it to the overcloud's authorized_keys files:

$ mistral execution-create tripleo.validations.v1.copy_ssh_key

Running validations using the mistral workflow

Create a context.json file containing the arguments passed to the workflow:

{
  "validation_names": ["512e", "rabbitmq-limits"]
}

Run the tripleo.validations.v1.run_validations workflow with mistral client:

mistral execution-create tripleo.validations.v1.run_validations context.json

Running groups of validations

Create a context.json file containing the arguments passed to the workflow:

{
  "group_names": ["network", "post-deployment"]
}

Run the tripleo.validations.v1.run_groups workflow with mistral client:

mistral execution-create tripleo.validations.v1.run_groups context.json
