How to run build stage in gitlab pipeline on branch creation?

问题

I have a gitlab pipeline which has two stages as shown below:

Below is my current .gitlab-ci.yml:

  stages:
    - build
    - push

  build:
    image: docker.repo.test.data/stuff/something:latest
    variables:
      LEGACY_VERSION: 10000
    before_script:
      - export CI_PIPE_ID=`expr $CI_PIPE_ID + $OLDER_VERSION`
    script:
      - echo "Building Project"
      - ls -lrth
      - ./build-project

  push:
    stage: push
    image: docker.repo.test.data/stuff/something:latest
    only:
        - master
    script:
      - some stuff here

In my build stage I try to build my project and in push stage I try to push it. My push stage only happens if any PR gets merged to master branch or any commit gets added to master branch as I am using only there.

Problem Statement

Now I want to run my build stage for below things as well:

• If someone creates a branch from master which starts with release-xxx name then I want to run only build stage.
• If someone creates a branch from a particular commit which starts with release-xxx name then I want to run only build stage.
• And for all other cases it should run build stage just like it is doing currently in my original .gitlab-ci.yml file.

Is this possible to do by any chance? Right now whenever I create a branch from master it doesn't run build stage.
