This commit updates vm usage stats collection to replace all instances of '.' characters within node strings. Without this change the node string containing a '.' character causes the metric to be interpreted as containing another node.
This commit updates providers_spec so the test ensures array content of the providers match. Without this change the provider_spec test will fail when comparing providers if the order is not exactly the same in each array.
This commit updates vmpooler to ship VM usage stats when a VM is destroyed. The stats are gathered for jobs based on user and pool name. If a jenkins build URL is present then this is broken down by user, instance, value stream, branch and project. Additionally, if present then the RMM_COMPONENT_TO_TEST_NAME will be listed after project. Without this change we do not collect stats on per VM usage and its correlation to users and pools.
This commit fixes checking of a VM that has already been identified as ready. Without this change a ready VM that has failed will be identified as having failed, but will not successfully be removed from the ready queue. Additionally, the default vm_checktime value has been reduced from 15 to 1 to ensure that ready VMs are checked within one minute of the time they have reached the ready state by default.
Lastly, the docker-compose files are updated to specify that the redis
instance used is a local redis instance.
This commit updates the dashboard for vmpooler to ensure it is synchronized with any redis based configuration values before displaying the dashboard. Without this change the pool size value may be displayed incorrectly if the value has been set via the /config/poolsize API endpoint.
This commit updates fetch_single_vm to return the name of the template that was requested, instead of the name of the pool providing the VM to meet the request. Without this change, when an alias is used for fetching a VM, a different pool title may be returned containing the requested VMs than the user initially requested.
This commit updates get_vm in the vmpooler API to allow for setting weights for backends. Additionally, when an alias for a pool exists, and the backend configured is not weighted, then the selection of the pool based on alias will be randomly sampled. Without this change any pool with the title of the alias is exhausted before an alternate pool with the configured alias is used, which results in an uneven distribution of VMs. When all backends involved are configured with weighted values the VM selection will be based on probability using those weights.
A bug is fixed when setting the default ttl for check_ready_vm.
Pickup is added to handle weighted VM selection.
A dockerfile is added that allows for building and installing vmpooler
from the current HEAD in docker to make for easy testing.
This commit updates delta disk creation to reduce the likelihood of this being run more than once for any given template. Without this change an error can be generated with vsphere 6.5 or later when a template is updated, and then the update is reverted. The error prevents the image from being used because the template is never marked as prepared. To address this any failure is now logged, and the template is marked as prepared regardless of whether this was successful, or not, which allows the image to be used despite the error. This failure mode is more graceful and allows the pool to continue to function.
This commit refactorss the check_pool method in pool_manager.
Specifically, each commented section describing a stage of check_pool is
broken out into a separate method and check_pool is simplified by
calling these methods. Without this change it is difficult to follow the
intent for or make changes to check_pool.
Additionally, a docker-compose file is added to make it simple to launch
an all-in-one vmpooler instance along with a separate redis server with
docker.
This commit updates destroy_vm to remove the redis member from the completed queue only after a destroy has been completed. Without this change a VM that is being destroyed will be logged as discovered when inventory is checked since it has already been removed from the completed queue.
This commit updates destroy_vm to remove references to its mutex tracking object when destroyed. Without this change a VM that is destroyed will leave its mutex tracking object forever causing the pool manager memory footprint to increase.
This commit adds documentation for specifying vmpooler configuration via environment variables. LDAP server is corrected to LDAP host, and the capability to specify graphite prefix and port is added. Vagrant documentation is moved into its own file to reduce noise in the main readme. Lastly, docker usage is updated to reflect that you no longer bake in a configuration file, and that API and manager can be run separately from docker via its entrypoint.
Prior to this commit the docs and examples used 'company.com'
(a real domain). This commit changes those occurrences to
'example.com', which is a IANA-managed reserved domain.
