我指的是开始在mesos上使用kubernetes并尝试部署 k8s 以及 Mesos 在同一个地方 Ubuntu . 执行以下命令：

$ km controller-manager \
  --master=${KUBERNETES_MASTER_IP}:8888 \
  --cloud-provider=mesos \
  --cloud-config=./mesos-cloud.conf  \
  --v=8 >controller.log 2>&1 &

从 controller.log :

$ more controller.log

经过调查，分为两个步骤：
（1） 使用 lsof 找到 http 连接：

lsof -p pid -P -n

（2） 使用 tcpdump 要捕获网络包：

sudo tcpdump -vv -A -s 0 'tcp port xxxx' -i em1 -w capture.pcap

然后分析包。
