Python Version Bumper

A simple Python script for updating the version in Kubernetes Helm Chart.yaml, VERSION, and pyproject.toml/setup.py files.

• Ensures version consistency across all files.
• Enforces Semantic Versioning 2.0.0.
• Supports an optional lowercase 'v' prefix (e.g., v1.5.4-beta2).

Installation

To install pybump, run:

pip install pybump

Usage

Bumping Versions

To bump the version:

pybump bump [-h] --file PATH_TO_CHART.YAML --level {major,minor,patch} [--quiet]

Setting Explicit Versions

To set an explicit version or automatically update release metadata:

pybump set --file PATH_TO_CHART.YAML --set-version X.Y.Z [--quiet]

The auto flag is primarily intended for CI/CD pipelines, such as pull request workflows:

pybump set --file PATH_TO_CHART.YAML --auto [--quiet]

When using --auto, pybump appends the Git commit hash as release metadata to the version.

• Warning - The --auto flag can be risky, as it may detect a Git repository unintentionally. Ensure that the target file is part of the correct repository before running this command.

Retrieving the Current Version

To get the current version:

pybump get --file PATH_TO_CHART.YAML

Updating Helm Chart appVersion

To bump, get, or set the appVersion field in a Helm chart, use the --app-version flag:

pybump bump [-h] --file PATH_TO_CHART.YAML --level {major,minor,patch} [--quiet] [--app-version]

Note

The --app-version flag applies only to Helm Chart.yaml files and has no effect on other file types.

Examples

CI Usage example

A simple Jenkins CI pipeline (using the Kubernetes plugin) that utilizes the set --file setup.py --auto option:

String label = "test-bump-ci-runner"
podTemplate(
        label: label,
        containers: [
                containerTemplate(
                        name: 'pybump',
                        image: "arielev/pybump:1.10.2",
                        ttyEnabled: true,
                        command: 'sleep',
                        args: '1d'
                ),
                containerTemplate(
                        name: 'jnlp',
                        image: 'jenkins/inbound-agent:jdk11',
                        ttyEnabled: true
                )
        ]
) {
    node(label) {
        timeout(time: 10, unit: 'MINUTES') {
            ansiColor('xterm') {
                String version = ""
                container('jnlp') {
                    git credentialsId: "credentials_id_here", url: "https://github.com/arielevs/pybump"
                }
                container('pybump') {
                    version = sh(
                            script: "pybump set --file setup.py --auto",
                            returnStdout: true
                    ).trim()
                }
                println(version)
            }
        }
    }
}
