Python实现通过Web执行Docker容器里面的shell命令

Posted on Edited on In ,

其实就是通过flask接受url传递过来的命令，然后调用SDK相关API执行docker exec命令，然后将结果返回给页面。

pip install flask docker

from flask import Flask
from flask import render_template
from flask import request
import docker

app = Flask(__name__, template_folder='./templates', static_folder="", static_url_path="")
client = docker.from_env()


@app.route('/cmd', methods=['GET', 'POST'])
def exec_cmd():
    if request.method == 'GET':
        return render_template('cmd.html')
    if request.method == 'POST':
        container = client.containers.get('gmb-index') # 这里我写死了获取本地这个容器
        cmd = request.form.get('cmd')
        result = container.exec_run(cmd=cmd)
        output = result.output.decode()
        return render_template('cmd.html', output=output)


if __name__=='__main__':
    app.run(host='127.0.0.1', port=8888)
