Drupal 8.x

I have ansible scripts which will install the Drupal. On the other hand, I have a website for which the database is pushed onto bitbucket. How can I perform CICD with these? My automation scripts will setup Drupal. How can I get the wesbite database on the newly installed plain Drupal?

I'm using ansible playbook via jenkins to install Drupal on some node (Linux machine). Once the Drupal is installed, I would like to get my website too. Is it possible in Drupal? If yes, how can I achieve it? 

Please help. Thanks in advance!

I am getting following errors when I update database using update.php.   Any  help?

I am a full time student and currently involved in a site development project in which I was task to add a url display under the title of each search result. The example handed to me was to add a green url display like the one that appears every time under the tittle of the pages you search in Google.

If further explanation is needed let me know.

I tried following this guide: https://www.drupal.org/docs/8/api/restful-web-services-api/custom-rest-resources for the REST API.

However, when enabling the module, I get:

Fatal error: Cannot declare class Drupal\my_module_rest_api\Plugin\rest\resource\MyModuleResource, because the name is already in use in [PATH]\modules\my_module\src\Plugin\rest\resource\MyModuleResource.php on line 0
