TravisCI: Run after_success on a specific branch

Question

I would like to know how to run an after_success script only for a specific branch.

I am using a custom script to deploy the app after build passes. I would

Answer 1

You can also do this by using the script provider in the deploy phase of your build. This approach is a bit cleaner but only allows one command, unlike after_success.

deploy:
  provider: script
  script: # some deployment script
  on:
    branch: prod

Answer 2

I solved it by writing a simple script using TRAVIS_BRANCH environment variable and executed the script in after_success

.travis.yml

after_success:
- ./deploy.sh

deploy.sh

#!/bin/bash
if [ "$TRAVIS_BRANCH" == "prod" ]; then
  // do the deploy
