kubernetes-国内拉取gcr.io\quay.io镜像方法 方法1: https://hub.docker.com/r/ibmcom/ 例如： gcr.io/google_containers/k8s-dns-kube-dns-amd64:1.14.4 docker pull ibmcom/k8s-dns-kube-dns:1.14.4 方法2: http://mirror.azure.cn/help/gcr-proxy-cache.html GCR Proxy Cache服务器相当于一台GCR镜像服务器，国内用户可以经由该服务器从gcr.io下载镜像。 例子： docker pull gcr.azk8s.cn/google_containers/pause-amd64:3.0 来源： https://www.cnblogs.com/wuhg/p/12191920.html

Get all DNS records associated with an IP

由 家住魔仙堡 提交于 2020-01-14 14:41:55
问题 Background The following code returns the IPv4 address of a given alias or host: [System.Net.Dns]::GetHostAddresses('someDnsName').IPAddressToString The below code returns the HostName (CName) and aliases of an IP: [System.Net.Dns]::GetHostByAddress('172.12.34.56') I'd therefore expect anything which returns an IP on GetHostAddresses to be listed under the HostName or Aliases of a call to GetHostByAddress (or at least for the FQDN of that item to be listed). i.e. I'd expect the result of the

SSL handshake hang

由 折月煮酒 提交于 2020-01-14 12:58:10
问题 I have seen this question around the forums but couldn't find any appropriate fix. Also all those questions are missing some info, so thought to put all what i have learned here. connecting the dots. I am working with SSL/TLS in openfire with 2 way authentication. Got a self signed wildcard certificate. which means i have my CA in both client and server. Now this works but sometimes, SSL handshake stucks at some particular line. Logs from server side: org.apache.mina.filter.ssl.SslFilter -

WWW vs non WWW — What's the best practice? I need to pick one for my new SSL Certificate [closed]

由 百般思念 提交于 2020-01-14 12:39:09
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . Should my site be a www or non-www address? This is a pretty basic question. I wanted to see what people consider to be the best practice here. The reason I have to pick is I need to buy an SSL certificate for one or the other. Of course I can redirect to the one I pick on the back-end and the technicals are not

006.kubernets之Deployment简单部署

由 假如想象 提交于 2020-01-14 09:43:45
一 Deployment相对于RC的优势 RS与Deployment主要用于替代RC。RS的全称为Replica Set。相对于RC，RS与Deployment的优势如下： RC只支持基于等式的selector，如env=dev或者environment!=qa。但在RS中，还支持新的基于集合的selector，如version in (v1.0,v2.0)或者env not in (dev,qa)。这给复杂的运维管理带来方便 使用Deployment升级Pod只需要定义Pod的最终状态，k8s会为你执行必要的操作。虽然使用kubectl rolling-update也可以完成滚动升级，但它是在客户端与服务端多次交互控制RC完成的，所以REST API中并没有rolling-update的接口，这为定制自己的管理系统带来了一些麻烦。Deployment拥有更加灵活的升级、回滚功能。 Replica Set目前与RC的区别只是支持的selector不同，后续会加入更多的功能。Deployment使用了Replica Set，是更高一层的概念。除非需要自定义升级功能或者根本不需要升级Pod，否则还是建议使用Deployment而不直接使用Replica Set。 二 Deployment是简单使用 2.1 同时安装三个nginx pod [root@docker-server1

Maximum number of domains that can be assigned to one Heroku app?

问题 I am discussing a project with a client who wants his users to access the app via their own domain name if they so choose… Is there a limit on the number of custom domains that can be assigned to one Heroku application? 回答1: There's no limit to the number of domains you can add on an app, from the docs: You can add any number of domains to a single app 回答2: The limit is now 10,000 custom domains per-app, according to Heroku's docs. 来源： https://stackoverflow.com/questions/15773920/maximum

Red hat linux ping: unknown host www.baidu.com

"ping: unknown host www.baidu.com" 解决方案： 如果某台Linux服务器ping不通域名, 如下提示: [root@localhost ~]# ping www.baidu.com ping: unknown host www.baidu.com 首先确定已经连接上路由器，并且路由器能够访问外网，可以通过访问网关进行确定 [root@localhost ~]# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=2.96 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=1.75 ms 如果确定网络没问题的情况下, 可以通过如下步骤寻找解决办法: 1) 确定设置了域名服务器, 没有的话, 建议设置Google的公共DNS服务, 它应该不会出问题的 [root@localhost ~]# cat /etc/resolv.conf search localdomain 因为我的DNS没有设置所以导致了ping外网ping不通。将dns添加到该文件中 [root@localhost ~]# vi /etc

Nginx 提示host not found in upstream 错误解决方法

由 好久不见. 提交于 2020-01-14 02:24:54
Nginx DNS resolver配置实例,本文讲解在proxy_pass 和 upstream server 通信的时候需要手动指定 resolver,本文就给出了配置实例. nginx 通过 proxy_pass 和 upstream server 通信的时候需要手动指定 resolver。某些时候 DNS 解析失败就会出现这个错误： domain.com could not be resolved. 可以指定多个 DNS 并重置域名 TTL 延长 nginx 解析缓存来保障解析成功率： resolver 223.5.5.5 223.6.6.6 1.2.4.8 114.114.114.114 valid=3600s; 如果还有解析错误，可以用 dnsmasq 在本地自建 DNS，顺带还有加速解析的好处： #/etc/dnsmasq.conf domain-needed bogus-priv cache-size=51200 listen-address=127.0.0.1 #server=223.5.5.5 resolv-file=/etc/resolv.conf 另外需要注意的是 proxy_pass 并不是每次请求都会进行解析，如果 upstream IP 频繁变动，需要强制解析: # via http://forum.nginx.org/read.php?2
