KDNS 配置中kni-vip地址是什么意思
; BGP 发布的VIP
kni-vip = 10.17.9.100
项目README中给出的kni-vip地址是什么意思呢？
没有修改的话，在
dns_tcp_process_init(g_dns_cfg->netdev.kni_vip);
调用处出错，提示：
KNI: pci: 04:00:00 8086:10c9
.........................done
Starting core 3 conf: rx=0, tx=1
Starting core 5 conf: rx=1, tx=2
Starting core 7 conf: rx=2, tx=3
bind: Cannot assign requested address
请教一下...
The version of the containerdns's k8sapi is too old
你好：
目前构建containerdns依赖的api有点老，还有etcd等，etcd的github地址已经变更了，dns的代码里面引的包还是老包，能否可以根据目前的相关库，更新一版代码？
多谢！
CentOS 7.5下make构建kdns需要做的几点调整
在CentOS 7.5下编译make build构建KDNS时，需要作如下小的调整:
- 修改DKDK包中的kni_net.c源代码，将代码中的中 ndo_change_mtu 用 ndo_change_mtu_rh74 替换
- 修改${SRC_HOME}/kdns/src/Makefile, 将
LDLIBS += -L$(SRCDIR)/../core/$(RTE_TARGET)/lib/ -lkdns 修改为
LDLIBS += -L$(SRCDIR)/../core/$(RTE_TARGET)/lib/ -lkdns –lgnutls - yum install –y texinfo
经过上述3步，KDNS构建OK。
README文档中的一处错误
[root@DPDK bin]# ./dpdk-devbind.py --bind=igb_uio kdns
Unknown device: kdns. Please specify device in "bus:slot.func" format
[root@DPDK bin]# ./dpdk-devbind.py --bind=igb_uio 06:00.1
0000:06:00.1 already bound to driver igb_uio, skipping
[root@DPDK bin]# ./dpdk-devbind.py --bind=igb_uio 06:00.2
[root@DPDK bin]#
dpdk-devbind.py --bind=igb_uio 06:00.1 的格式才正确，最后一个参数是PCIE网卡的bus:slot.func
containerdns配置问题
我这里使用了一台机器10.1.61.129来部署containerdns，服务器系统为centos7.2
/etc/containerdns/containerdns.conf配置如下：
[Dns]
dns-domains = wh01 #wh01为我这里使用的域名
dns-addr = 0.0.0.0:53
ex-nameservers = "10.1.61.120:53"
#inDomainServers = [email protected]:53%[email protected]:53
inDomainServers =""
cacheSize = 1000000
ip-monitor-path = /containerdns/monitor/status/
[Log]
log-dir = /export/log/containerdns
log-level = 0
log-to-stdio = true
[Etcd]
etcd-servers = http://127.0.0.1:2379 #使用本地的etcd
etcd-certfile = ""
etcd-keyfile = ""
etcd-cafile = ""
[Fun]
random-one = false
hone-one = false
[Stats]
statsServer = 127.0.0.1:9600
statsServerAuthToken = @containerdns.com
启动如下：
[root@op-yanwei containerdns]# /usr/local/containerdns/bin/containerdns &> /export/log/containerdns/containerdns.log &

/etc/containerdns/containerdns-api.conf配置如下：
[General]
#这一行本来也是按照github上的示例配置，加上的，但加上了，就直接抛can't store data at section "General", variable "domain"异常，注释掉这一行，则正常

我的理解是，通过日志应该可以看出已经成功从kubernetes拿到域名信息，但这个时候，我检查etcd，发现etcd下并没有出现/containerdns 相关的key，如下：
[root@op-yanwei containerdns]# etcdctl ls
[root@op-yanwei containerdns]#
etcd仍然是空的。
我将/etc/resolv.conf的解析修改到当前dns：
namserver 10.1.61.129
尝试解析：
[root@op-yanwei containerdns]# nslookup olympic-stress.default.svc.wh01
Server: 10.1.61.129
Address: 10.1.61.129#53
** server can't find olympic-stress.default.svc.wh01: NXDOMAIN
并没有拿到解析结果。
我通过containerdns-apicmd尝试查询抛出如下异常：
[root@op-yanwei containerdns]# /usr/local/containerdns/bin/containerdns-apicmd -token abcdef123456789 -addr 127.0.0.1:9003 -domain wh01 -list
domain : not found
[root@op-yanwei containerdns]# /usr/local/containerdns/bin/containerdns-apicmd -token abcdef123456789 -addr 127.0.0.1:9003 -domain wh01 -show wh01
domain :wh01 not found
我以为是组件还没安装完，那我先全部安装再尝试，再次配置dns-scanner，配置文件/etc/containerdns/containerdns-scanner.conf如下：

至此，containerdns的部署彻底失败！
我所有的配置文件及配置过程基本参考都来源于github上的文档及http://www.infoq.com/cn/articles/jd-618-container-dns-practise 这篇文档，很多配置荐其义不明，也是半配置单猜测半测试。。。
请帮忙看下到底是个什么情况 ？
EAL设置相关问题讨论
KDNS的配置文件kdns.cfg中，EAL相关的内存设置没有说明
memory = 1024,1024
这个配置应该是指在NUMA架构下node0， node1 分别分配
1024个2MB的Hugepage大页内存的意思， 个人推测 ?
mem-channels = 4 这个配置项是什么意思呢？
请开发者说明一下，谢谢！
containerdns-kubeapi编译问题
1、在编译containerdns-kubeapi的时候，抛出一大堆异常，后来经过反复测试，是需要依赖指定的kubernetes版本，通过kubernetes 1.5版本，完成编译后，结果到处都找不到编译完成后的containerdns-kubeapi的二进制包。。。
2、如果找到这个包的话，在最新的kubernetes 1.8版本中监视1.8的service，又是否会兼容？
第一张图有个red应该是read吧~

kdns服务的启动的相关问题
./kdns启动后 日志文件中提示：
[2019-01-28 10:48:36.879] [25441] [error] : now just one port supported
经查看源码, netdev,c源程序中：
/* Get number of ports found in scan */
nb_sys_ports = rte_eth_dev_count();
if (nb_sys_ports == 0){
log_msg(LOG_ERR, "No supported Ethernet device found\n");
exit(-1);
}
if (nb_sys_ports != 1){
log_msg(LOG_ERR, "now just one port supported\n");
exit(-1);
}
进入DPDK的usertools目录，运行dpdk-setup.sh查看 DPDK Driver与网口的bind绑定配置情况：

是不是只需要绑定一个网络接口才能正常启动kdns服务？
有没有官方群什么的？
