Travis CI can automatically release your Python package to PyPI after a successful build.
For a minimal configuration, all you need to do is add the following to your
deploy: provider: pypi user: "Your username" password: "Your password"
Most likely, you would only want to deploy to PyPI when a new version of your package is cut. To do this, you can tell Travis CI to only deploy on tagged commits, like so:
deploy: provider: pypi user: ... password: ... on: tags: true
If you tag a commit locally, remember to run
git push --tags to ensure that your tags are uploaded to GitHub.
Assuming you have the Travis CI command line client installed, you can encrypt your password like this:
travis encrypt --add deploy.password
You will be prompted to enter your password on the command line.
You can also have the
travis tool set up everything for you:
$ travis setup pypi
Keep in mind that the above command has to run in your project directory, so it can modify the
.travis.yml for you.
Branch to release from
You can explicitly specify the branch to release from with the on option:
deploy: provider: pypi user: ... password: ... on: branch: production
Alternatively, you can also configure Travis CI to release from all branches:
deploy: provider: pypi api_key: ... on: all_branches: true
By default, Travis CI will only release from the master branch.
Builds triggered from Pull Requests will never trigger a release.
Releasing to a different index:
If you wish to release to a different index you can do so:
deploy: provider: pypi user: ... password:... server: https://mypackageindex.com/index
Uploading different distributions
By default, only a source distribution (‘sdist’) will be uploaded to PyPI.
If you would like to upload different distributions, specify them using the
distributions option, like this:
deploy: provider: pypi user: ... password: ... distributions: "sdist bdist_wheel" # Your distributions here
If you specify
bdist_wheel in the distributions, the
wheel package will automatically be installed.
Releasing build artifacts
After your tests ran and before the release, Travis CI will clean up any additional files and changes you made.
Maybe that is not what you want, as you might generate some artifacts that are supposed to be released, too. There is now an option to skip the clean up:
deploy: provider: pypi user: ... password: ... skip_cleanup: true
You can deploy only when certain conditions are met.

Running commands before and after release
Sometimes you want to run commands before or after releasing a package. You can use the
after_deploy stages for this. These will only be triggered if Travis CI is actually pushing a release.
before_deploy: "echo 'ready?'" deploy: .. after_deploy: - ./after_deploy_1.sh - ./after_deploy_2.sh
