AWS自动化运维脚本分享

AWS自动化运维脚本分享

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。

相关示例:

$ ./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]

examples:
  ./awscli.py --create --region us-west-1 --instance_name idc1-server2 --image_id ami-30f01234 --instance_type t1.micro \
              --key_name idc1-keypair1 --security_group_ids sg-eaf01234f --subnet_id subnet-6d901234

              --volume_size 10 --volume_type gp2 --volume_zone us-west-1a --volume_delete_on_termination \
              --load_balancer_name idc1-elb1 --private_ip_address 172.16.2.23
