Python实现通过Web执行Docker容器里面的shell命令

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。

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)
