Docker container images delete command summary 1. show all docker container : $ docker ps -a -q stop all running container : docker stop $(docker ps -a -q) then you can delete all images : $ docker rm $(docker ps -a -q) 2. show all images : $ docker images 3. delete one image by id : $ docker rmi <image id> delete untagged images, which id is <None> : $ docker rmi $(docker images | grep "^<none>" | awk "{print $3}") delete all images : $ docker rmi $(docker images -q) last thanks!

背景 现在我在福建海峡互联网金融信息服务有限公司，老板考虑企业转型，才被逼着考虑买上深行情，但是因为钱的问题，不知道会不会买。他最近一直让我问上、深所的数据报价。 以前像我们公司这种做现货的小金融公司太多，国家查得严，最近倒了很多，我们老板不想倒，才考虑做合规产品。 这样没有后顾之忧，以后要上市要融资了，这些都会查的。 下面是个人最近2017年上半年咨询行情报价的情况汇总，仅供参考，不做为确切真实依据，如果有侵权，请告知，第一时间删除。 汇总情况 于上深交所 Level1 服务费用包括：数据提示牌照费用 + 数据传输费用。       如我们现在急着只需要微信和移动的 Level1 单平台无线增值平台证券行情费用，预计需要上交所牌照费用 30 万 / 年 + 上交所 Internet 数据传输免费 + 深交所牌照费用 30 万 / 年 + 深圳通云数据传输费用（ 8000/ 年 +8 万 / 年） =68.8 万 / 年（预计）。其中正式购买后才可以申请最长不超过 2 个月的测试期。       另外关于目前炒股软件里的财经 F10 新闻资讯巨潮资讯由深交所信息公司提供，价格见附件《巨潮数据库服务报价单 2016.pdf 》， 因为隐私问题，如需商务使用，可私人联系我索要 。      Level1 数据提示牌照授权费 深交所牌照费用 : PC 电脑终端 30 万 / 年，无线终端（微信 +APP ） 30 万 / 年，或者同时采购两款平台价格打 8 折 = （ 30+30 ） *0.8=48 万 / 年。 上交所牌照费用 : 单平台终端报价与深交所类似，但两款平台同时采购价约 45 万 / 年。 注意：深交所有要求，一次性申请两个应用可以打八折，如果你们 分开申请，比如先申请无线， 过半年后再申请软件，是不能打折的。以后年度就是续约了。。。按照合同来续约的。         上交所暂未确认此打折疑问。 Level1 数据汇总费用   采购一款深 Level1 平台价格 =...

What: Spring boot feignclient call other instance show below error: com.netflix.client.ClientException: Load balancer does not have available server for client: Why: if eureka.client.fetchRegistry is false, the various shuffle methods in com.netflix.discovery.shared.Applications are not called and hence Applications.shuffleVirtualHostNameMap is never populated. This map is used later for look up in the method Applications.getInstancesByVirtualHostName that then fails. How: eureka:   client:     registerWithEureka: true     fetchRegistry: true # change to true, is ok Last: Thanks
