containerdns's Issues

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。

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 &
[1] 9646
[root@op-yanwei containerdns]# tail -f /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
#domain=wh01
host   = 10.1.61.129
etcd-server = http://127.0.0.1:2379
etcd-certfile = ""
etcd-keyfile = ""
etcd-cafile = ""
ip-monitor-path = /containerdns/monitor/status
log-dir    = /export/log/containerdns
log-level  = 4
log-to-stdio = TRUE
[Kube2DNS]
kube-domain = wh01.
kube-enable = YES
kube-config-file = /etc/containerdns/bootstrap.kubeconfig
#kube-enable=NO
[DNSApi]
api-enable = YES
api-domains = wh01.
api-address = 0.0.0.0:9003
containerdns-auth  =  abcdef123456789

配置文件中/etc/containerdns/bootstrap.kubeconfig配置如下：

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCk1JSURqRENDQW5TZ0F3SUJBZ0lVTFpHVG4wSWdCZS9iS1NXVTRSYlhSb0lxMm1Bd0RRWUpLb1pJaHZjTkFRRUwKQlFBd1RERUxNQWtHQTFVRUJoTUNRMDR4RGpBxxxxxxxxxxxxxxx

启动container-kubeapi：

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：

[General]
core = 0
enable-check = true
hostname = 10.1.61.129
log-dir = /export/log/containerdns

heart-path = /containerdns/monitor/heart

启动：

/usr/local/containerdns/bin/dns-scanner &>/export/log/containerdns/containerdns-scanner.log &

直接异常退出，检查日志如下：

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？

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：
Option: 23

No 'Crypto' devices detected

No 'Eventdev' devices detected

No 'Mempool' devices detected

是不是只需要绑定一个网络接口才能正常启动kdns服务？

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！

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

请教一下...

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？

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！
