ebs_conductor¶ ↑
The EBS Conductor is a library for managing Amazon Elastic Block Storage volumes and snapshots. It is designed to persist a specific set of data (a “lineage”) between different compute instances.
EBS Conductor can be used on it’s own, but it’s most powerful when executed on an EC2 instance using Chef, and the ebs_conductor cookbook
Examples¶ ↑
Attach a new 1GB blan volume in the lineage “foobar” to a linux box at /dev/sdb1¶ ↑
ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.attach_from_lineage('i-abcd1234', 'foobar', 1, '/dev/sdb1')
Attach a specific snapshot to a 1GB volume in the lineage “foobar” to a linux box at /devb/sdb1¶ ↑
ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...')
ebs_conductor.attach_from_lineage('i-abcd1234', 'foobar', 1, '/dev/sdb1' {:snapshot_id => 'snap-abcd1234'})
Snapshot the lineage “foobar”, do not purge any old snapshots in the lineage¶ ↑
ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.snapshot_lineage('foobar')
Snapshot the lineage “foobar”, and purge old snapshots so that only 7 remain¶ ↑
ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.snapshot_lineage('foobar', {:history_to_keep => 7})
Snapshot the lineage “foobar” from the specified volume_id¶ ↑
This is useful if you’re trying to start a lineage from a “naked” instance, or if you are trying to create a new lineage from an existing one
ebs_conductor = Rgeyer::Gem::EbsConductor.new('...','...') ebs_conductor.snapshot_lineage('foobar', {:history_to_keep => 7, :volume_id => 'vol-abcd1234'})
