Can I deploy my Content on drupal using scripts? If suppose I have a drupal application in Github and I have automated drupal installation using chef. Now I want to deploy that application content such that i can see it on my content page. 
I am unable to put php and drupal tags due to reputation.
If you would like to automate your deploys of content, just like you automate your code deploys, you'll probably want to look into the migrate module.  This model is best for sites where the content is managed by a content-generation team; it is less applicable for sites that have a lot of user-generated content.  This is a viable model that some people use, though, and is a very compelling workflow if your use-case supports it. One good extant site that uses this technique and has a public GitHub repository is Gizra's Negawatt.
