Version updater for components in your codebase

Problem to solve

In the project where there are many components to track new versions (docker images and pypi packages) this tool automates finding new versions, running tests and commit changes to git.

TL;DR

Create YAML file with definition of your components (see example in tests/test_files/components.yaml ). Place components.yaml in the root of your project directory and run:

>>> python -m updater check
10 components to check
1 components to update

>>> python -m updater check --verbose
10 components to check
1 components to update
pymongo - current: 3.12.1 next: 3.12.2

This will check versions for all components defined in components2.yaml:

>>> python -m updater --file=/path/to/your/components2.yaml check
10 components to check
1 components to update

Here is an example of update script which will do checking and print out updated config file without making any changes in your files:

>>> python -m updater --dry-run --print update

Here is full example of using update command:

>>> python -m updater update --git-commit --test-command="make test"

It will, for each defined component in components.yaml from the local directory:

1. Check if there are new versions of your components available

2. Replace in all files version numbers to the newest one

3. Run tests

4. Add and commit changes to git

Installation

Install via pypi packages repository:

>>> python -m pip install updater

YAML Config file format

Example of components definition:

# name of the component
python:
   # docker-image or pypi
   component-type: docker-image
   # this version tak needs to aligned with versions in files
   # if you put "latest" then check and update will be skipped for this component
   current-version: 3.6.6-alpine3.8
   # for docker-image component-type only
   docker-repo: library
   # filter used to get all possible versions
   filter: /^\d+\.\d+\.\d+-alpine\d+\.\d+$/
   # files in which version number should be replaced
   files: [locust/Dockerfile, locust/some_script.sh]
   # this is the find (current version) and replace (new version) pattern.
   # {version} and {component} can be used
   version-pattern: "PYTHON_VERSION {version}"
   # if there are different patterns in particular files, you can specify them here
   # file level pattern overrides component level pattern
   files-version-pattern:
      - file: locust/Dockerfile
         pattern: PYTHON_VERSION={version}
      - file: locust/some_script.sh
         pattern: version {version}
Django:
   component-type: pypi
   current-version: 2.2.24
   filter: /^\d+\.\d+(\.\d+)?$/
   files: [app/requirements.txt]
logspout:
   component-type: docker-image
   current-version: v3.1
   docker-repo: gliderlabs
   filter: /^v\d+\.\d+\.\d+$/
   # if there is prefix before numeric part of version, you can specify it here
   prefix: v
   files: [logspout/Dockerfile-logspout]
   # put here versions which should be skipped
   exclude-versions: [v3.2.6]

Import python packages to components.yaml

If you want to “copy” python packages to components.yaml from requirements.txt, pipfile (pipenv) or Poetry (project.toml) you need use import-req command with --source set to one of requirements, pipfile or poetry. In each cases the --requirements-file param needs to point at requirements.txt like file but will set proper version-pattern and files.
