How to restrict branch creation based on pattern in Bitbucket

Question

I am using Atlassian Bitbucket server v4.8.6.

How do I restrict restrict branch creation based on pattern.

Rules explained below -

1. Only ABC team should be able to create release/ABC-*
2. Only XYZ team should be able to create personal/XYZ-*

Answer 1

You can't create rules to prevent only the "creation" of branches. These are the avaliable restrictions:

Prevent all changes
Prevent deletion
Prevent rewriting history
Prevent changes without a pull request

To create branch permissions do the following:

1. Go to Repository > Settings > Branch permissions > Add permissions
2. Select "Branch pattern"
3. Add branch pattern, ex: release/ABC-*
4. Select one of the restrictions available
5. Add the group exception, ex: ABC

Answer 2

This can be done by adding "*" on Select branch text field. See the screenshot below.

1. Go to your repository > Settings > Branch permissions > Add permission

2. Under "Select branch - By name or pattern", put an asterisk (*)

3. Save

After that, you can restrict each branch patterns you want for different teams or people.

ABC group

1. Select branch = release/ABC-*

2. Write access = ABC group or ABC members

Personal branch

1. Select branch = personal/XYZ-*

2. Write Access = Your account
