如何在openshift上为我现有的应用程序升级NodeJS？

Question

I have an application running on OpenShift using NodeJS 0.10 but now I want to upgrade it to latest 0.12. I added to package.json :

  "engines": {
    "node": ">= 0.12.0",
    "npm": ">= 1.0.0"
  },

I also followed https://blog.openshift.com/any-version-of-nodejs-you-want-in-the-cloud-openshift-does-it-paas-style/ and got NODEJS_VERSION marker in .openshift folder.

I stopped app, started again but cant get it to run NodeJS 0.12. I tried to remove NodeJS cartridge but I get 'nodejs-0.10' cannot be removed message. I also follwed accepted answer OpenShift not working with certain Nodejs dependencies (Koa) but when I get to openshift page it seems that I can only deploy new application but I just need to upgrade existing app.

Is there any way to upgrade existing app nodeJs version on openshift?

Answer 1

Just to say that OpenShift is updating to NodeJS 5.10. I didn't find documentation about that, but I have created an application few days ago and a new option is showing up when selecting the cartridge to use. I can see both options:

Node.js 0.10 (first option)

Node.js (Latest) (last option)

Maybe it's a good idea to test it!
