背景介绍:目前项目中使用了大量的AWS EC2 Instances作为服务器,在自动化运维方面,我们之前一直使用的是AWS CLI命令行工具,然后在Shell脚本中调用.

最近我想通过脚本实现一个“Clone”的功能,模拟Web Console上的“Launch More Like This”来创建Instance,但在Shell脚本中实现起来感觉不太舒服,于是就直接利用Python的boto库写了一个,在此分享给大家.

具体内容:

相关示例:温馨提示:我的Blog页面默认没有采用宽屏模式,如果觉得下面的代码不太美观,可以点击右上角的“<>”切换到宽屏模式,代码如下:

$ ./awscli.py -h

usage: awscli.py [-h] (--create | --clone | --terminate) --region REGION

                 [--instance_name INSTANCE_NAME] [--image_id IMAGE_ID]

                 [--instance_type INSTANCE_TYPE] [--key_name KEY_NAME]

                 [--security_group_ids SECURITY_GROUP_IDS]

                 [--subnet_id SUBNET_ID]

                 [--src_instance_name SRC_INSTANCE_NAME]

                 [--dest_instance_name DEST_INSTANCE_NAME]

                 [--private_ip_address PRIVATE_IP_ADDRESS]

                 [--instance_id INSTANCE_ID] [--volume_size VOLUME_SIZE]

                 [--volume_type {standard,io1,gp2}]

                 [--volume_zone VOLUME_ZONE] [--volume_iops VOLUME_IOPS]

                 [--volume_delete_on_termination]

                 [--load_balancer_name LOAD_BALANCER_NAME]

                 [--quick]
