How to run a single deploy when Travis builds succeeds?

Question

I am running Travis CI using matrix of Python versions but I do want to execute the release actions only after all of these are passed, obviously.

How can I do this? It seems that the "deploy" actions are executed for each sub-build.

Answer 1

It seems that this is not currently possible and there is a bug tracking it at: https://github.com/travis-ci/travis-ci/issues/929

Update

Travis disables commenting on that issue which is really a bad thing. I guess you only option now is to tweet them to reopen it. Use social pressure, works against closed business models! ;)

Also if you happen to know some competitors that do allow this, mention them! ... in the same tweet.

Answer 2

It is possible by using bash and Travis built-in variables. For a JavaScript / Node repo that would be:

dist: trusty
language: node_js
node_js:
  - '8'
  - '7'
install: ...
script: ...
after_success:
  - 'if [ "${TRAVIS_NODE_VERSION}" = "8" ]; then cat ./coverage/lcov.info | coveralls ; fi'
  - 'if [ "${TRAVIS_NODE_VERSION}" = "8" ]; then firebase deploy --token $FIREBASE_TOKEN --non-interactive ; fi'

Other built-in variables:

• TRAVIS_DART_VERSION
• TRAVIS_GO_VERSION
• TRAVIS_HAXE_VERSION
• TRAVIS_JDK_VERSION
• TRAVIS_JULIA_VERSION
• TRAVIS_NODE_VERSION
• TRAVIS_OTP_RELEASE
• TRAVIS_PERL_VERSION
• TRAVIS_PHP_VERSION
• TRAVIS_PYTHON_VERSION
• TRAVIS_R_VERSION
• TRAVIS_RUBY_VERSION
• TRAVIS_RUST_VERSION
• TRAVIS_SCALA_VERSION
