Below is a summarization created by an LLM (gpt-4-0125-preview). Be mindful of hallucinations and verify accuracy.

Why

The changes introduce Docker-TC as a replacement for Pumba to manage Docker-based chaos experiments, addressing Docker API compatibility issues. It adds the ability to create, manage, and remove various network conditions (delay, loss, corruption, and duplication) on containers directly, enhancing the testing framework's capabilities in simulating real-world scenarios for better resilience testing.

What

• framework/.changeset/v0.14.8.md
  • Adds a changeset note about replacing Pumba with Docker-TC.
• framework/chaos/chaos.go
  • Adds imports and constants related to Docker-TC commands and configuration.
  • Implements DockerChaos struct and methods for initializing Docker-TC, applying, and removing chaos experiments.
  • Marks the previous ExecPumba method as deprecated, indicating a shift towards using Docker-TC for chaos experiments.
• framework/chaos/chaos_test.go
  • Adds new test file for chaos package, including tests for various Docker-TC chaos experiments (pause, delay, loss, corrupt, duplicate) on a container, validating the functionality of the DockerChaos implementation.
• framework/components/fake/fake.go
  • Minor cleanup by removing an extraneous newline and adjusting import formatting, unrelated to the main Docker-TC changes but likely for code cleanliness.
