Releasetool (for client libraries)

This tool helps create releases for cloud client libraries.

Presently, this works for Python, Node.js, and Ruby. However, it's designed in such a way that it could easily be used for other languages.

Installation

Requirements:

• Python 3.8+
• pip

We recommend following this guide for installing both Python 3 and pip.

Install releasetool using pip:

python3 -m pip install gcp-releasetool

Usage

Packages are published in two phases. First, a PR is created to update CHANGELOG.md and the version number. Second, once the PR is merged the merge commit is tagged and CI publishes the package.

To start the process of releasing use releasetool start from the directory of the client you want to publish, for example:

git clone git@github.com:googleapis/google-cloud-python.git
cd google-cloud-python
cd bigquery
releasetool start

This will create a PR.

If the PR has a autorelease: pending label:

Upon approval and merging, autorelease will pick up the PR and run releasetool tag and release the package to their respective package managers. Autorelease will comment on the release PR with the status of the release. Example PR

Otherwise:

Once the PR has been approved and merged, you can run releasetool tag from anywhere in the repository to tag the commit and start CI.

git fetch origin master
git checkout origin/master
releasetool tag

Authenticating

When first running releasetool you will be prompted for a GitHub token. Make sure that the token provided has write:repo_hook and public_repo scopes.

Resetting the GitHub Token

If you need to change the GitHub API token associated with releasetool, run releasetool reset-config. This will delete the existing token. The next time you run releasetool start you will be prompted to enter a new token.
