主机设备信息和配置

我在 docker 容器中托管我的 owncloud 实例。我熟悉 docker 技术和可能性，但实际“操作”对我来说很新。目前我不确定我的主机设备是否像我预期的那样授予网络访问权限/速度（docker 容器使用桥接千兆位接口br0）。

主机设备信息和配置

我的主机设备支持千兆位：

tharmar@nuc:~$ dmesg |grep em1 
[    2.249914] e1000e 0000:00:19.0 em1: renamed from eth0 
[    2.262696] systemd-udevd[125]: renamed network interface eth0 to em1 
[    5.290467] device em1 entered promiscuous mode 
[    8.430199] e1000e: em1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None 
[    8.430231] br0: port 1(em1) entered forwarding state 
[    8.430240] br0: port 1(em1) entered forwarding state 
[   17.434250] br0: port 1(em1) entered forwarding state

我手动将主机 /etc/network/interfaces 更改为以下配置：

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#auto em1
#iface em1 inet dhcp
auto br0
iface br0 inet dhcp
    bridge_ports em1
    bridge_fd 9
    bridge_hello 2
    bridge_maxage 12
    bridge_stp off

我根据网上找到的教程（手头没有链接）调整了 br0 配置。在我的主机上，我达到了以下下载速度：

  • 互联网 = 5,64MB/s
  • 内部网络 = 88.0MB/s

Docker 容器信息

  • 图片：l3iggs/owncloud
  • 运行命令：

docker run --restart=always -v /media/500GB/owncloud/config:/usr/share/webapps/owncloud/config -v /media/500GB/owncloud/data:/usr/share/webapps/owncloud/data --name oc -p 80:80 -p 443:443 -d l3iggs/owncloud

docker 网络

tharmar@nuc:~$ docker network ls
NETWORK ID          NAME                DRIVER

ab858df7af57        host                host

docker network inspect bridge（我在这个网络中找到了我的容器）

    },

            "IPv4Address": "172.17.0.3/16",
            "IPv6Address": ""
        }
        }
    },
    "Options": {
        "com.docker.network.bridge.default_bridge": "true",
        "com.docker.network.bridge.enable_icc": "true",
        "com.docker.network.bridge.enable_ip_masquerade": "true",
        "com.docker.network.bridge.host_binding_ipv4": "0.0.0.0",
        "com.docker.network.bridge.name": "docker0",
        "com.docker.network.driver.mtu": "1500"
    }
}

有人能告诉我瓶颈在哪里吗？我配置错了吗，还是根本没有配置？

如果您确实需要更多有关我的环境的信息，请随时询问，我会尽快更新问题。
