我才刚刚开始探索OpenShift Online 3，看起来真的很棒。我正在尝试设置一个简单的HTTP服务器。这是我使用的步骤CLI：
我当前的工作文件夹包含两个文件package.json和server.js。
Package.json
{
"name": "test",
"version": "0.0.1",
"description": "Node.js app for OpenShift 3",
"main": "server.js",
"dependencies": {
"express": "^4.13.4"
},
"engine": {
"node": "*",
"npm": "*"
},
"scripts": {
"start": "node server.js"
}
}
Server.js
const express = require('express')
const app = express()
const port = process.env.PORT || process.env.OPENSHIFT_NODEJS_PORT || 8080
const ip = process.env.IP || process.env.OPENSHIFT_NODEJS_IP || '0.0.0.0'
app.get('/', function (req, res) {
res.status(200).send({ message: 'OK' })
})
// error handling
app.use(function(err, req, res, next){
console.error(err.stack)
res.status(500).send('Something bad happened!')
})
app.listen(port, ip)
console.log('Server running on http://%s:%s', ip, port)
module.exports = app
这是控制台输出：
--> Creating resources ...
imagestream "olmeo-openshift" created
buildconfig "olmeo-openshift" created
deploymentconfig "olmeo-openshift" created
service "olmeo-openshift" created
--> Success
Build scheduled, use 'oc logs -f bc/olmeo-openshift' to track its progress.
Run 'oc status' to view your app.
构建完成后，Web控制台显示错误：
Environment:
DEV_MODE=false
NODE_ENV=production
DEBUG_PORT=5858

显然，package.json找不到。我想念什么？
如果您使用：
oc new-app .
在从远程托管的Git存储库中克隆的git工作区中，将建立构建以从托管的Git存储库中提取文件。这意味着，如果您进行本地更改，并且不将其添加/提交/推送到托管的Git存储库，则将永远不会使用它们。
如果要从本地目录工作而不使用托管的Git存储库，则需要使用二进制输入构建。为此，请首先运行：
oc new-build --binary --image-stream nodejs --name olmeo-openshift
然后运行以下命令开始构建：
oc start-build olmeo-openshift --from-dir=.
这将从本地目录上载文件。
构建第一个映像后，即可运行：
oc new-app olmeo-openshift
部署映像，并：
oc expose svc/olmeo-openshift
给它一个公共URL。
每次更改代码时，请再次运行：
oc start-build olmeo-openshift --from-dir=.
