This DEMO project is used for running Chaos Experiment
/actuator/chaosmonkey- Chaos Monkey for Spring Boot/employee/all- Return employees from DB (H2)
Mac : Set virtual environment in python and install chaostoolkit-spring
python3 -m venv ~/.venvs/chaostk
source ~/.venvs/chaostk/bin/activate
pip install chaostoolkit-spring
Win : Set virtual environment in python and install chaostoolkit-spring
python3 -m venv {project_path}/.venvs/chaostk
source {project_path}/.venvs/chaostk/scripts/activate
pip install chaostoolkit-spring
pip install chaostoolkit
Run the experiment:
chaos run {path_of_experiement_folder}/experiments.json
Output When Experiment is successful:
