  2. Security Group IPアドレスを一括で置換する src_ip = 'x.x.x.x/32' dst_ip = 'y.y.y.y/32' ec2.security_groups.each

    do |src_sg| puts "#{src_sg.id}, #{src_sg.name}" src_sg.ip_permissions.each do |p| if p.ip_ranges.include? src_ip src_sg.authorize_ingress(p.protocol, p.port_range, dst_ip) src_sg.revoke_ingress(p.protocol, p.port_range, src_ip) end end end 14 36
  3. S3 期間限定URIを生成 s3 = AWS::S3.new b = s3.buckets['your-bucket-name'] o =

    b.objects['object-name'] puts o.url_for(:read, :expires => 60*60*24*31) 一ヶ月間有効なURLが生成される 15 36
  4. 最新のSnapshot as = [] ec2.volumes.each do |v| v.attachments.each do |a|

    as << a end end ss = {} r.snapshots.sort {|a,b| b.start_time <=> a.start_time }.map do |s| ss[s.volume_id] = s unless ss.include? s.volume_id end as.each do |a| vid = a.volume.id if ss.include? vid puts "#{a.instance.id} => (#{ss[vid].start_time})" end end 18 36
  5. AWS.memoize AWS.memoize do ss = {} r.snapshots.sort {|a,b| b.start_time <=>

    a.start_time }.map do |s| ss[s.volume_id] = s unless ss.include? s.volume_id end end ソートしている部分を AWS.memoizeで囲むだけ 20 36
  6. Snapshotの一覧 解決策: filter ec2.snapshots.filter( 'owner-id', 'YOUR_ACCOUNT_NUMBER').each do |s| # ...

    end 自分のアカウント番号を指定すると 自分のSnapshotのみ取得できる。 26 36
