Configuration updates for latest builds and major refactor
Configuration updates for latest builds - Switch to using create-node-config - Switch sdn services to use etcd over SSL - This re-uses the client certificate deployed on each node - Additional node registration changes - Do not assume that metadata service is available in openshift_facts module - Call systemctl daemon-reload after installing openshift-master, openshift-sdn-master, openshift-node, openshift-sdn-node - Fix bug overriding openshift_hostname and openshift_public_hostname in byo playbooks - Start moving generated configs to /etc/openshift - Some custom module cleanup - Add known issue with ansible-1.9 to README_OSE.md - Update to genericize the kubernetes_register_node module - Default to use kubectl for commands - Allow for overriding kubectl_cmd - In openshift_register_node role, override kubectl_cmd to openshift_kube - Set default openshift_registry_url for enterprise when deployment_type is enterprise - Fix openshift_register_node for client config change - Ensure that master certs directory is created - Add roles and filter_plugin symlinks to playbooks/common/openshift-master and node - Allow non-root user with sudo nopasswd access - Updates for README_OSE.md - Update byo inventory for adding additional comments - Updates for node cert/config sync to work with non-root user using sudo - Move node config/certs to /etc/openshift/node - Don't use path for mktemp. addresses: https://github.com/openshift/openshift-ansible/issues/154 Create common playbooks - create common/openshift-master/config.yml - create common/openshift-node/config.yml - update playbooks to use new common playbooks - update launch playbooks to call update playbooks - fix openshift_registry and openshift_node_ip usage Set default deployment type to origin - openshift_repo updates for enabling origin deployments - also separate repo and gpgkey file structure - remove kubernetes repo since it isn't currently needed - full deployment type support for bin/cluster - honor OS_DEPLOYMENT_TYPE env variable - add --deployment-type option, which will override OS_DEPLOYMENT_TYPE if set - if neither OS_DEPLOYMENT_TYPE or --deployment-type is set, defaults to origin installs Additional changes: - Add separate config action to bin/cluster that runs ansible config but does not update packages - Some more duplication reduction in cluster playbooks. - Rename task files in playbooks dirs to have tasks in their name for clarity. - update aws/gce scripts to use a directory for inventory (otherwise when there are no hosts returned from dynamic inventory there is an error) libvirt refactor and update - add libvirt dynamic inventory - updates to use dynamic inventory for libvirt

+GCE external inventory script
+=================================
+
+Generates inventory that Ansible can understand by making API requests
+Google Compute Engine via the libcloud library. Full install/configuration
+instructions for the gce* modules can be found in the comments of
+ansible/test/gce_tests.py.
+
+When run against a specific host, this script returns the following variables
+based on the data obtained from the libcloud Node object:
+ - gce_uuid
+ - gce_id
+ - gce_image
+ - gce_machine_type
+ - gce_private_ip
+ - gce_public_ip
+ - gce_name
+ - gce_description
+ - gce_status
+ - gce_zone
+ - gce_tags
+ - gce_metadata
+ - gce_network
+
+When run in --list mode, instances are grouped by the following categories:
+ - zone:
+ zone group name examples are us-central1-b, europe-west1-a, etc.
+ - instance tags:
+ An entry is created for each tag. For example, if you have two instances
+ with a common tag called 'foo', they will both be grouped together under
+ the 'tag_foo' name.
+ - network name:
+ the name of the network is appended to 'network_' (e.g. the 'default'
+ network will result in a group named 'network_default')
+ - machine type
+ types follow a pattern like n1-standard-4, g1-small, etc.
+ - running status:
+ group name prefixed with 'status_' (e.g. status_running, status_stopped,..)
+ - image:
+ when using an ephemeral/scratch disk, this will be set to the image name
+ used when creating the instance (e.g. debian-7-wheezy-v20130816). when
+ your instance was created with a root persistent disk it will be set to
+ 'persistent_disk' since there is no current way to determine the image.
+
+Examples:
+ Execute uname on all instances in the us-central1-a zone
+ $ ansible -i gce.py us-central1-a -m shell -a "/bin/uname -a"
+
+ Use the GCE inventory script to print out instance specific information
+ $ plugins/inventory/gce.py --host my_instance
