Hosting Website On Openshift
I decided to migrate my web to OpenShift. It was a bit frustrating but I got it working eventually.
Things to know before taking the leap
Some domain providers don’t support CNAME changes for root domains (zimmi.cz in my case). This means you can’t simply tell your domain to serve content from OpenShift address. But what you can do is to tell your
www subdomain to do so:
www.zimmi.cz CNAME hp-zimmi.rhcloud.com
Which is great until you realize you’ve just created two different websites. That’s where wwwizer lends you a hand and lets you redirect your naked domain to your
zimmi.cz A 18.104.22.168
Now everything works fine and you have your
www.domain.tld up and running.
I wasn’t successful creating a subdomain on the same application where I run my domain. This can be easily solved by creating another application and pointing DNS to it:
posts.zimmi.cz A 22.214.171.124 www.posts.zimmi.cz CNAME posts-zimmi.rhcloud.com
Just don’t forget to handle both naked and
www version. When Google reindexes new URLs (http://www.zimmi.cz/posts instead of http://posts.zimmi.cz) subdomain application might be deleted.
