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.
Previously it was difficult to do local development as VMPooler requires an LDAP
service for authentication. This commit adds a dummy authentication provider.
The provider has passes authentication if the username and password are
different, and fails if the username and password are the same. This commit
also updates the documentation in the config YML file.
* rename the Redis token 'timestamp' var to 'created'
* update the Redis token 'last' var when token is successfully validataed
* expose the Redis token 'last' var in GET /token route
This moves the inline Helpers contained in V1.rb to their own file:
helpers.rb. In making this change, any API.settings call was removed
from the helper method itself and passed through from V1.
This also adds tests for hostname shortener and validate date string.
