This change adds a capability to vmpooler to provision instances on
demand. Without this change vmpooler only supports retrieving machines
from pre-provisioned pools.
Additionally, this change refactors redis interactions to reduce round
trips to redis. Specifically, multi and pipelined redis commands are
added where possible to reduce the number of times we are calling redis.
To support the redis refactor the redis interaction has changed to
leveraging a connection pool. In addition to offering multiple
connections for pool manager to use, the redis interactions in pool
manager are now thread safe.
Ready TTL is now a global parameter that can be set as a default for all
pools. A default of 0 has been removed, because this is an unreasonable
default behavior, which would leave a provisioned instance in the pool
indefinitely.
Pool empty messages have been removed when the pool size is set to 0.
Without this change, when a pool was set to a size of 0 the API and pool
manager would both show that a pool is empty.
This change updates handling of pool aliases to allow for more than a
single pool to be configured as an alias pool. Without this change if
multiple pools are configured as an alias the last one to configure it
is set as the alias for that pool.
Additionally, redis testing requirements are removed in favor of
mock_redis. Without this change a redis server is required to run
vmpooler tests.
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.
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.
