如何在python脚本中使用awscli？

How to use awscli inside python script?

提问by e271p314

I'm using aws ec2 service with awscli. Now I want to put all the commands I type in the console into a python script. I see that if I write import awscliinside a python script it works fine but I don't understand how to use it inside the script. For instance how do I execute the commands aws ec2 run-instances <arguments>inside the python script after import awscli? Just to make it clear, I'm not looking for a solution like os.system('aws ec2 run-instances <arguments>'), I'm looking for something like

我正在将 aws ec2 服务与 awscli 一起使用。现在我想将我在控制台中键入的所有命令放入一个 python 脚本中。我看到如果我import awscli在 python 脚本中编写它可以正常工作，但我不明白如何在脚本中使用它。例如，我如何在之后执行aws ec2 run-instances <arguments>python 脚本中的命令import awscli？为了清楚起见，我不是在寻找类似的解决方案os.system('aws ec2 run-instances <arguments>')，而是在寻找类似的解决方案

import awscli
awscli.ec2_run-instances(<arguments>)

The CLI would be more suited for the shell prompt, for a better python API, check the boto library. This example shows how to launch an instance: http://boto.readthedocs.org/en/latest/ec2_tut.html

CLI 更适合 shell 提示，要获得更好的 Python API，请查看 boto 库。此示例显示如何启动实例：http: //boto.readthedocs.org/en/latest/ec2_tut.html

You can do it with brilliant shpackage. You could mimic python package with sh doing wrapping for you.

你可以用辉煌的sh包来做到这一点。你可以用 sh 为你做包装来模仿 python 包。

import sh
s3 = sh.bash.bake("aws s3")
s3.put("file","s3n://bucket/file")

Boto3 doesn't have everything the cli has so you may have to use something from the cli in a script once in a blue moon. I can't find an analog for aws deploy push in boto3 for example so here is how I push to s3 with the cli from a python script. Although to Julio's point, I use boto for everything else.

Boto3 没有 cli 的所有功能，因此您可能需要在脚本中使用 cli 中的某些内容。例如，我在 boto3 中找不到 aws deploy push 的模拟，所以这里是我如何使用 python 脚本中的 cli 推送到 s3。尽管就胡里奥而言，我将 boto 用于其他一切。

import subprocess

cmd='aws deploy push --application-name SomeApp --s3-location  s3://bucket/Deploy/db_schema.zip --ignore-hidden-files' 
push=subprocess.Popen(cmd, shell=True, stdout = subprocess.PIPE)
print push.returncode
