env:
LB_CONFIG_FILE: ".github/lennybot.yaml"
LB_GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
Install package with pip install lennybot.
To start the application run the lennybot command.
You can specify the Action which should be executed.
This action can be "ci", "plan" or "apply".
The CI CLI action executed apply and handles git operations such as, commit and branch creation.
The plan action allows to plan updates and save the plan for later.
The apply action can either execute an existing plan, or create a new plan and apply it immediately.
To run the lennybot as docker image execute:
docker run --rm -v "$(pwd):/workspace/ raynigon/lennybot
The lennybot allows to define multiple applications.
Each application has to have a version source, which can be queried to determine the latest version.
If a newer version is available, the lennybot executes multiple pre defined actions per application.
E.g. Update Docker Image Tags.
The applications, sources and actions can be configured in the config.yml file.
For more information see below.
The lennybot can be configured via the config.yml file and environment variables.
If the config.yml file is not in the root of the current working directory, the LB_CONFIG_FILEenvironment variable can be used to pass the location of the configuration file to the lennybot.
The configuration file has multiple top level objects. Each section represents a configuration object.

Once upon time a colleague (Lenny) left my team. Besides being an Apache Solr genius, one of the tasks he really liked doing, was the updating of the dependencies in our applications. Since everyone else in the team didnt like this job, we needed some automation for this. The lennybot was born to replace our colleague. Since then the lennybot evolved and finally got replaced by the dependabot. Some years later i needed a solution to upgrade components managed with kustomize. This lead to the creation of a new lennybot which is able to automatically search for updates and upgrades the resources with their latest versions.
