This commit updates vmpooler gem dependencies in Gemfile and gemspec files. Without this change vmpooler is pinned to out of date version of multiple libraries.
This commit adds the spicy-proton gem to vmpooler.gemspec. Without this change the spicy-proton gem is in the Gemfile, but not the gemspec, causing issues when deploying from gem.
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 gemspec and Gemfile in preparation of a vmpooler release. To support this change the vmpooler executable is placed into a bin directory for inclusion in the gem. The license in gemspec is updated to Apache 2.0 to reflect the vmpooler project license.
