与Popen在Python中的docker exec命令

Question

我正在开发一个与docker容器交互的应用程序。

我想以 docker exec name_of_container命令方式执行此命令： command= "/usr/bin/balance -b "+ ip_address + " 5001 " + servers_list

我们的想法是执行 echo 命令 ＆gt;＆gt; / etc / supervisor / conf.d / supervisord.conf` < / p>

我尝试如下：

p=subprocess.Popen(['docker','exec','supervisor','echo','command'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)

但它不起作用。

这是错误代码：

exec: "'/usr/bin/balance -b 195.154.12.1 5001 192.186.13.1' >> /etc/supervisor/conf.d/supervisord.conf": stat '/usr/bin/balance -b 195.154.12.1 5001 192.186.13.1' >> /etc/supervisor/conf.d/supervisord.conf: no such file or directory
