OodReservations

Library that queries a cluster for active reservations of the current user.

Installation

Add this line to your application's Gemfile:

gem 'ood_reservations'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ood_reservations

Usage

Given an OodCluster::Cluster object you can build a query object that can query all reservations on the cluster or a specified reservation id:

# Create a query object (creates a TorqueMoab query object)
query = OodReservations::Query.build(cluster: my_torque_moab_cluster)
#=> #<OodReservations::Queries::TorqueMoab>

# Create a query object (this cluster has no scheduler to query)
query = OodReservations::Query.build(cluster: my_cluster_w_no_scheduler)
#=> nil

To query reservations:

# Query all reservations you have on that cluster
rsvs = query.reservations
#=>
#[
#  #<OodReservations::Reservation>,
#  #<OodReservations::Reservation>
#]

# Query for unique reservation id
my_rsv = query.reservation(id: 'my_rsv.23874')
#=> #<OodReservations::Reservation>

An OodReservations::Reservation object has information about the given reservation:

# Has this reservation started yet?
my_rsv.has_started?
#=> true

# Has this reservation ended yet?
my_rsv.has_ended?
#=> false

# Get list of users/groups that have access to this reservation
my_rsv.users.map(&:name)
#=> ["bob", "sally", "me"]

my_rsv.groups.map(&:name)
#=> ["group1", "group2"]

# List all nodes on reservation
my_rsv.nodes.map(&:id)
#=> ["n0001", "n0002"]

# List nodes that have no jobs running on them
my_rsv.free_nodes.map(&:id)
#=> ["n0002"]
