How to run a command only if this is the main branch in travis-ci?

Question

I have an open source project, and I want to deploy the code only if the code is in the main branch, I have already tried many approaches, for example:

- if [[ $TRAVIS_BRANCH == 'master' ]]; then fab deploy; fi 

Or something like:

 BRANCH = "master" def _get_local_branch(): return local("git rev-parse --abbrev-ref HEAD", capture=True) def deploy(): local_branch = _get_local_branch() if local_branch == BRANCH: print green("Deploy succefully done!") print yellow("Deploy allowed just in the master branch.") 

But this does not work, even in other branches of people, the fab deploy command was called.

I'm not sure why your first approach does not work, but I would suggest using the deploy: directive in your .travis.yml file with a custom deployment script as follows:

 deploy: provider: script script: scripts/deploy.sh on: branch: master 

Here is the documentation .

Hope this helps.
