From 8fe4fff91f296dd6dc7efcf2b7e9422406d90741 Mon Sep 17 00:00:00 2001 From: Mark Goddard Date: Fri, 26 Feb 2016 19:23:28 +0200 Subject: [PATCH] Contribute core Cray changes to Bareon This is a contribution of features made in the scope of Cray Bareon adoption. Even though changes affect a lot of code, they are not breaking. To proove that we have created a functional test that covers existing nailgun deployment flow (see /tests_functional/test_nailgun.py) We have made Manager a deploy_driver. Current nailgun's manager has been moved to nailgun deploy driver, which is default. Most of the changes made in the scope of the project are enclosed within Ironic data driver and Ironic (swift & rsync) deploy drivers. To make this review easier I propose the following order: Review changes to existing code: - review changes to object model - review changes related to splitting deploy driver / base drivers - review changes to common utils Review the new code: - review Ironic data driver - review Ironic deploy drivers Change-Id: Id2d32a7574e6fcafee09490c39fb114c80407db7 Implements: blueprint size-unit-conversion-and-relative-sizing Implements: blueprint policy-based-partitioning Implements: blueprint multi-image-deployment Implements: blueprint rsync-image-deployment --- README.md | 2 +- bareon/cmd/agent.py | 31 +- bareon/drivers/data/__init__.py | 0 bareon/drivers/{ => data}/base.py | 16 + bareon/drivers/{ => data}/bootstrap.py | 2 +- bareon/drivers/data/generic.py | 173 ++++ bareon/drivers/data/ironic.py | 754 ++++++++++++++ bareon/drivers/data/json_schemes/__init__.py | 0 bareon/drivers/data/json_schemes/ironic.json | 198 ++++ bareon/drivers/data/json_schemes/nailgun.json | 99 ++ bareon/drivers/data/ks_spaces_validator.py | 56 ++ bareon/drivers/{ => data}/nailgun.py | 69 +- bareon/drivers/{ => data}/simple.py | 2 +- bareon/drivers/deploy/__init__.py | 0 bareon/drivers/deploy/base.py | 54 + bareon/drivers/deploy/generic.py | 606 +++++++++++ .../{manager.py => drivers/deploy/nailgun.py} | 32 +- bareon/drivers/deploy/rsync.py | 40 + bareon/drivers/deploy/swift.py | 131 +++ bareon/drivers/ks_spaces_validator.py | 149 --- bareon/errors.py | 12 + bareon/objects/image.py | 23 +- bareon/objects/partition/fs.py | 13 +- bareon/objects/partition/parted.py | 5 +- bareon/objects/partition/scheme.py | 23 +- bareon/tests/test_build_utils.py | 7 + bareon/tests/test_generic_data_driver.py | 181 ++++ bareon/tests/test_generic_deploy_driver.py | 732 ++++++++++++++ bareon/tests/test_grub_utils.py | 19 +- bareon/tests/test_hardware_utils.py | 163 ++- bareon/tests/test_ironic.py | 445 ++++++++ bareon/tests/test_ironic_data_driver.py | 949 ++++++++++++++++++ .../tests/test_ironic_ks_spaces_validator.py | 242 +++++ bareon/tests/test_ks_spaces_validator.py | 3 +- bareon/tests/test_lvm_utils.py | 22 - bareon/tests/test_manager.py | 162 +-- bareon/tests/test_nailgun.py | 261 ++--- bareon/tests/test_nailgun_build_image.py | 4 +- .../tests/test_nailgun_ks_spaces_validator.py | 251 +++++ bareon/tests/test_partition.py | 4 + bareon/tests/test_partition_utils.py | 69 +- bareon/tests/test_rsync_deploy_driver.py | 49 + bareon/tests/test_simple_nailgun_driver.py | 2 +- bareon/tests/test_utils.py | 27 +- bareon/utils/fs.py | 12 +- bareon/utils/grub.py | 94 +- bareon/utils/hardware.py | 172 +++- bareon/utils/partition.py | 51 +- bareon/utils/utils.py | 44 +- setup.cfg | 20 +- 50 files changed, 5883 insertions(+), 592 deletions(-) create mode 100644 bareon/drivers/data/__init__.py rename bareon/drivers/{ => data}/base.py (82%) rename bareon/drivers/{ => data}/bootstrap.py (96%) create mode 100644 bareon/drivers/data/generic.py create mode 100644 bareon/drivers/data/ironic.py create mode 100644 bareon/drivers/data/json_schemes/__init__.py create mode 100644 bareon/drivers/data/json_schemes/ironic.json create mode 100644 bareon/drivers/data/json_schemes/nailgun.json create mode 100644 bareon/drivers/data/ks_spaces_validator.py rename bareon/drivers/{ => data}/nailgun.py (96%) rename bareon/drivers/{ => data}/simple.py (98%) create mode 100644 bareon/drivers/deploy/__init__.py create mode 100644 bareon/drivers/deploy/base.py create mode 100644 bareon/drivers/deploy/generic.py rename bareon/{manager.py => drivers/deploy/nailgun.py} (98%) create mode 100644 bareon/drivers/deploy/rsync.py create mode 100644 bareon/drivers/deploy/swift.py delete mode 100644 bareon/drivers/ks_spaces_validator.py create mode 100644 bareon/tests/test_generic_data_driver.py create mode 100644 bareon/tests/test_generic_deploy_driver.py create mode 100644 bareon/tests/test_ironic.py create mode 100644 bareon/tests/test_ironic_data_driver.py create mode 100644 bareon/tests/test_ironic_ks_spaces_validator.py create mode 100644 bareon/tests/test_nailgun_ks_spaces_validator.py create mode 100644 bareon/tests/test_rsync_deploy_driver.py diff --git a/README.md b/README.md index f5aece7..895e944 100644 --- a/README.md +++ b/README.md @@ -114,7 +114,7 @@ This folder contains the python code: drivers, objects, unit tests and utils, ma - bareon/cmd/agent.py * That is where executable entry points are.
