* (POOLER-81) Add time_remaining information
Before, the only time calculation displayed for a given VM was the
lifetime parameter. Added the remaining parameter which will
display time until the VM is destroyed as a float.
Additionally, start_time and end_time were added to api to return
as UTC based times (e.g. 2018-07-10 11:01:03 -0700).
* Remove abs eval from GET, rework spec tests to check each field.
This allows us to account for "flakiness" of the remaining return.
* Change datetime to RFC3339 for start_time and end_time
* Revert "(POOLER-34) Ship clone request to ready time to metrics (#277)"
This reverts commit a865e6bd2f.
* Revert "(POOLER-81) Add time_remaining information (#276)"
This reverts commit 1910cffaf7.
* (POOLER-81) Add time_remaining information
Before, the only time calculation displayed for a given VM was the
lifetime parameter. Added the time_remaining parameter which will
display time until the VM is destroyed in hours, minutes, seconds.
Additionally, updated the running parameter to display in a similar
fashion as time_remaining.
* Add spec testing for testing time_remaining stat
This commit removes a additional authenticate method that is defined in the token_spec tests. Instead, authenticate is used from api/helpers. To support this change the config provided is updated to specify a dummy provider. Without this change authenticate cannot be tested along with token_spec because token_spec redefines authenticate.
This commit updates vmpooler to support setting an array of search bases
in addition to a single base provided as a string. Without this change
it is not possible to specify multiple search bases to use with the LDAP
authentication provider. Additionally, test coverage is added to
the authentication helper method.
This commit adds a configuration endpoint to the vmpooler API. Pool
size, and pool template, can be adjusted for pools that are configured
at vmpooler application start time. Pool template changes trigger a pool
refresh, and the new template has delta disks created automatically by
vmpooler.
Additionally, the capability to create template delta disks is added to
the vsphere provider, and this is implemented to ensure that templates
have delta disks created at application start time.
The mechanism used to find template VM objects is simplified to make the flow of logic easier to understand. As an additional benefit, performance of this lookup is improved by using FindByInventoryPath.
A table of contents is added to API.md to ease navigation. Without this change API.md has no table of contents and is difficult to navigate.
Add mutex object for managing pool configuration updates
This commit adds a mutex object for ensuring that pool configuration changes are synchronized across multiple running threads, removing the possibility of two threads attempting to update something at once, without relying on redis data. Without this change this is managed crudely by specifying in redis that a configuration update is taking place. This redis data is left so the REPOPULATE section of _check_pool can still identify when a configuration change is in progress, and prevent a pool from repopulating at that time.
Add wake up event for pool template changes
This commit adds a wake up event to detect pool template changes.
Additionally, GET /config has a template_ready section added to the
output for each pool, which makes clear when a pool is ready to populate
itself.
The status endpoint provides a lot of statistics. This commit extends it
by supporting a query parameter called 'view' which may contain one or
multiple comma separated names for the top-level statistics returned
in the JSON response. status is always returned.
Optional elements are capacity,queue,clone,boot,pools
Everything is returned when 'view' is not specified, which is
backwards compatible with the current behavior.
Before this change if a pool had an alias configured, the information would not be
made public in the API. This commit adds the alias key in the pool object for each
pool if configured. The alias key can be abscent, a string or an one or multiple
array of strings. The value of the alias is copied from the configuration and can
represent another name for the pool, or another configured pool.
Previously all of the spec tests for VM Pooler were all together in the specs
directory. However some tests require a working local Redis server to operate
and other instead mock all external dependencies. This commit splits the test
files between unit and integration, where integration tests require a working
Redis instance, and unit tests do not. This commit also removes the root
`vmpooler` directory as it is not required. The tests rake test still operates
correctly.
This commit also adds the mock_redis library for testing for the pool_manager.
