pass env variables to travis specific to deployment

Question

i have the following .travis.yaml file:

branches:
  only:
    - master
    - develop
language: node_js
node_js:
  - "7.9.0"
script:
  - make build
deploy:
  - provider: s3
    local_dir: build
    acl: public_read
    skip_cleanup: true
    bucket: "app-dev-us-east-1"
    region: "us-east-1"
    on:
      branch: develop
  - provider: s3
    local_dir: build
    acl: public_read
    skip_cleanup: true
    bucket: "app-prod-us-east-1"
    region: "us-east-1"
    on:
      branch: master

in my script: make build, what is the correct way to pass a different env variable based on the branch that is being built?

or do i have to modify my makefile and pull the TRAVIS_BRANCH and use that?

any advise is much appreciated

Answer 1

Actually this question was already asked before .

One of answers says that you can have different .travis.yml on each branch. However the issue would be with merging between those branches. But you can always add .travis.yml to .gitignore to ignore these differences during merge.
