自从过去3到4年以来我一直在使用Heroku,现在我有客户想要使用openshift来进行ruby应用程序部署.
我知道heroku功能和openshift的新功能.我知道openhift的一些功能,如齿轮,墨盒,市场等.
两者都使用aws进行在线服务和相同的git部署策略.
我想知道opensuift over heroku的优势是什么来部署ruby应用程序？
在Tomcat的官方页面中,它说Tomcat 7支持Java 8.如果我下载它并使用Java 8运行它可以工作.
但是,在Openshift上是Tomcat 7(JBoss EWS 2.0).在这个网页中,它说EWS 2.0 不支持Java 8.如果我将我的Java 8应用程序部署到Openshift(Tomcat 7),它就无法运行.
为什么？
我尝试在Openshift上使用Tomcat 7安装Java 8:https://stackoverflow.com/a/23895161/2442133 但它并不适合我.我有错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean

我似乎遇到了一个简单的问题,感觉我错过了一些必不可少的东西.
我在我们公司有一个私人码头图像注册表,它托管我们开发的所有docker图像.
在我们的构建过程中不断更新此注册表,并且经常将新图像推送到它.
现在我们正在使用一个openshift系统,它有一些图像和它自己的注册表.
在这两个系统之间同步图像的最佳方法是什么？
例如,我们有一个像这样部署的应用程序:
oc new-app myregistry.mydomain.edu/binbase/minix
运行得很好.
我们现在想用最新的更改更新此部署,为此我做了:
oc import-image minix
标签规格创建PullSpec图像最近23小时前myregistry.mydomain.edu/binbase/minix:latest f6646382cfa32da291e8380421ea656110090256cd195746a5be2fcf61e4edf1
这是正确的图像,现在执行一个
oc deploy minix --latest
但这仍然部署当前图像,而不是新更新的图像.
知道为什么这个,或者我们做错了什么？
所有我想要todo现在重新部署最新的图像.
亲切的问候
我用NodeJS创建了一个应用程序,我正在使用ws模块.如果我在localhost中测试应用程序它是有效的,连接websockets没有任何问题.现在我已将应用程序上传到Openshift,当我尝试从客户端访问时,它返回无法建立与websocket的连接.
如果我在我的应用程序中使用putty尾部,我会收到以下消息:DEBUG:这种类型的响应不能有一个正文.忽略传递给end()的数据.
我在服务器中的代码是:
#!/bin/env node
//Openshift variables
var ipaddress = process.env.OPENSHIFT_NODEJS_IP || "192.168.69.42";
var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;
//NodeJS require modules
var Enum = require('enum');
var WebSocketServer = require('ws').Server
wss = new WebSocketServer({host:ipaddress, port:port});
var fs = require('fs');
wss.on('connection', function(ws) {
console.log((new Date()) + ' Connection from origin: ' + ws._socket.remoteAddress);
});
console.log((new Date()) + " Server is listening on: " + ipaddress + ':' port);
在客户端:
var ws = new WebSocket("ws://192.168.69.42:8080/");
ws.onopen = function() { …我在OpenShift上使用WordPress小型齿轮盒.

我一直在经历其他SO问题并遵循他们的建议但到目前为止还没有解决我的问题.
