get bitbucket to ignore bitbucket-pipelines.yml

[Gavin Thomas]

I have set up a branch strategy of :

Dev - Deploys to Dev and then promote to preprod

master - deploys directly production

Reason for this is the headless cms is triggering the master build to build the site when the content changes via a webhook. If i work on dev or create branches off dev i want to merge changes into master when i'm happy and bitbucket to ignore the pipelines file as they are different. 

Is it possible to do this?

i've added it to gitignore but wheni do a diff it's saying the file is different

 Or can i run different branch pipelines from 1 config file?
