Service Mesh Chaos Engineering

Gloo Shot is a chaos engineering framework for service meshes.

START pre-release notes >>>>>>>>>>>>>>>>>>>>>

:::: TODO ::::

High-level

• get CI running
• require approvals before commit
• cli
• documentation
• publish documentation to glooshot.solo.io
• demo app
• tutorial app
• fill in the Readme
• link with Squash (in demo at least)
• basic ui for demo purposes
• e2e tests

Core features

• Experiment specification
• Results report

E2E Tests (BDD)

• make test and check off list as features are implmented
• CLI should allow user to define an experiment
• CLI should allow user to start an experiment
• CLI should allow user to terminate an experiment
• CLI should allow user to schedule an experiment for later
• CLI should allow user to define auto-termination conditions for experiments
• CLI should allow user to view results??
  • results will manifest as system metrics, what sort of report summary should Glooshot produce?
• Glooshot should watch Experiment CRDs and respond to their changes
• Glooshot should clean up all of its resources
• Glooshot should be able to deploy concurrent experiments
• Glooshot should be able terminate one experiment without affecting others
• Glooshot should be able to verify that an experiment is active
• (P2) CLI should provide simple before/during experiment stats

Details

• watch experiment crds from glooshot
• create sample yamls for experiments
• document how to create experiments from cli (with kubectl)

Research

• identify api gaps
• connect to istio
• connect to appmesh
• connect to linkerd

:::: Development Notes ::::

How to run

• see DEVELOPMENT

Verify status

kubectl port-forward -n deploy/glooshot 8085
## check the dummy endpoints
curl localhost:8085
# expect "Hello from default"
curl localhost:8085/todo
# expect "TODO"

Summary

• Using Gloo Shot
• What makes Gloo Shot unique

Using Gloo Shot

• Harden your mesh: Gloo Shot allows you to test failure modes before they occur in production.
• Preview architectural changes: Real deployments have different performance characteristics than your production environment. Gloo Shot allows you to simulate your productionn environment (latency, faults, etc.) prior to deployment.

What makes Gloo Shot unique

• Integration with the most popular service meshes: Gloo Shot was designed for service mesh environments. It leverages Supergloo for a consistent interface to multiple different service meshes.

Thanks

Gloo Shot would not be possible without the valuable open-source work of projects in the community. We would like to extend a special thank-you to Envoy.
