今天给大家介绍的是如何用AWS Boto3 Python SDK创建EC2
首先我们安装Boto 3 SDK:
pip install awscli boto3
然后我们本地配置AWS的秘钥key
aws configure
示例输入
$ aws configure
AWS Access Key ID [None]: ABCDEFGHIJKLMNOPQRST
AWS Secret Access Key [None]: abcdefghijklmnopqrstuvwxyz1234567890
Default region name [None]: us-west-2
Default output format [None]: json接下来我们使用Python配置登录EC2服务器的SSH key pair:
import boto3
ec2 boto3.resource(ec2)# create a file to store the key locally
outfile open(ec2-keypair.pem,w)# call the boto ec2 function to create a key pair
key_pair ec2.create_key_pair(KeyNameec2-keypair)# capture the key and store it in a file
KeyPairOut str(key_pair.key_material)
print(KeyPairOut)
outfile.write(KeyPairOut)
创建成功后我们利用Python创建一个EC2服务器同时在EC2创建时启动NGINX。
import boto3ec2 boto3.resource(ec2)# User data script to install Nginx
user_data_script #!/bin/bash
sudo apt-get update
sudo apt-get install -y nginx
sudo service nginx start
# Create a new EC2 instance
instances ec2.create_instances(ImageIdami-00b6a8a2bd28daf19,MinCount1,MaxCount2,InstanceTypet2.micro,KeyNameec2-keypair,UserDatauser_data_script
)# Print the instance IDs
for instance in instances:print(fCreated instance with ID: {instance.id})对于保护EC2运行提高云服务的稳定性、可用性我们要定期为EC2创建镜像。在AWS上镜像的形式叫做AMI以下是常见AMI的代码。
import boto3ec2 boto3.client(ec2)# Replace with your instance ID
instance_id i-1234567890abcdef0# Create an AMI from the instance
response ec2.create_image(InstanceIdinstance_id,NameMyServerImage,DescriptionAn AMI of my server,NoRebootTrue # Set to False if you want to reboot the instance before creating the image
)image_id response[ImageId]
print(fAMI created with ID: {image_id})如果我们想重启、删除一个EC2服务器可以用以下代码
重启
import boto3ec2 boto3.client(ec2)# Replace with your instance ID
instance_id i-1234567890abcdef0# Reboot the instance
response ec2.reboot_instances(InstanceIds[instance_id]
)print(fRebooted instance: {instance_id})删除
import boto3ec2 boto3.client(ec2)# Replace with your instance ID
instance_id i-1234567890abcdef0# Terminate the instance
response ec2.terminate_instances(InstanceIds[instance_id]
)print(fTerminated instance: {instance_id})对于EC2维护和访问如果可以分配固定IP将会保证EC2重启后IP保持不变。我们使用如下代码实现IP固定分配Elastic IP
import boto3ec2 boto3.client(ec2)# Allocate a new Elastic IP address
response ec2.allocate_address(Domainvpc
)allocation_id response[AllocationId]
print(fElastic IP allocated with ID: {allocation_id})# Replace with your instance ID
instance_id i-1234567890abcdef0# Associate the Elastic IP with the instance
response ec2.associate_address(InstanceIdinstance_id,AllocationIdallocation_id
)print(fElastic IP associated with instance: {instance_id})
