Roadmap
LITMUS ROADMAP¶
This document captures only the high level roadmap items. For the detailed backlog, see issues list.
Completed¶
- Declarative Chaos Intent via custom resources
- Chaos Operator to orchestrate chaos experiments
- Off the shelf / ready chaos experiments for general Kubernetes chaos
- Self sufficient, Centralized Hub for chaos experiments
- Per-experiment minimal RBAC permissions definition
- Creation of 'scenarios' involving multiple faults via Argo-based Chaos Workflows (with examples for microservices apps like podtato-head and sock-shop)
- Cross-Cloud Control Plane (Litmus Portal) to perform chaos against remote clusters
- Helm charts for LitmusChaos control plane
- Helm Chart for LitmusChaos execution Plane
- Support for admin mode (centralized chaos management) as well as namespaced mode (multi-tenant clusters)
- Continuous chaos via flexible schedules, with support to halt/resume or (manual/conditional) abort experiments
- Provide complete workflow termination/abort capability
- Generation of observability data via Prometheus metrics and Kubernetes chaos events for experiments
- Steady-State hypothesis validation before, during and after chaos injection via different probe types
- Support for Docker, Containerd & CRI-O runtime
- Support for scheduling policies (nodeSelector, tolerations) and resource definitions for chaos pods
- ChaosHub refactor for 2.x user flow
- Support for ARM64 nodes
- Minimized role permissions for Chaos Service Accounts
- Scaffolding scripts (SDK) to help bootstrap a new chaos experiment in Go, Python, Ansible
- Support orchestration of non-native chaos libraries via the BYOC (Bring-Your-Own-Chaos) model
- Support for OpenShift platform
- Workflow YAML linter addition
- Integration tests & e2e framework creation for control plane components and chaos experiments
- Documentation (usage guide for chaos operator, resources & developer guide for new experiment creation)
- Improved documentation and tutorials for Litmus Portal based execution flow
- Add architecture details & design resources
- Define community sync up cadence and structure
In-Progress (Under Design OR Active Development)¶
- Native Chaos Workflows with redesigned subscriber to improve resource delegation, enabling seamless and efficient execution of chaos workflows within Kubernetes clusters.
- Introduce transient runners to improve resource efficiency during chaos experiments by dynamically creating and cleaning up chaos runner instances.
- Implement Kubernetes connectors to enable streamlined integration with Kubernetes clusters, providing simplified authentication and configuration management.
- Integrate with tools like K8sGPT to generate insightful reports that identify potential weaknesses in your Kubernetes environment before executing chaos experiments.
- Add Terraform support for defining and executing chaos experiments on infrastructure components, enabling infrastructure-as-code-based chaos engineering.
- Add SDK support for Python and Java, with potential extensions to other programming languages based on community interest.
- Include in-product documentation, such as tooltips, to improve user experience and ease of adoption.
- Implement the litmus-java-sdk with a targeted v1.0.0 release by Q1.
- Integrate distributed tracing by adding attributes or events to spans, and create an OpenTelemetry demo showcasing chaos engineering observability.
- Enhance the exporter to function as an OpenTelemetry collector, providing compatibility with existing observability pipelines.
- Add support for DocumentDB by replacing certain MongoDB operations, improving flexibility for database chaos.
- Upgrade Kubernetes SDK from version 1.21 to 1.26 to stay aligned with the latest Kubernetes features and enhancements.
- Refactor the chaos charts to:
- Replace latest tags with specific, versioned image tags.
- Consolidate multiple images into a single optimized image.
- Update GraphQL and authentication API documentation for improved clarity and user guidance.
- Add comprehensive unit and fuzz tests to enhance code reliability and robustness.
- Implement out-of-the-box Slack integration for better collaboration and monitoring during chaos experiments.
Backlog¶
- Validation support for all ChaosEngine schema elements within workflow wizard
- Chaos-center users account to chaosService account map
- Cross-hub experiment support within a Chaos Workflow
- Enhanced CRD schema for ChaosEngine to support advanced CommandProbe configuration
- Support for S3 artifact sink (helps performance/benchmark runs)
- Chaos experiments against virtual machines and cloud infrastructure (AWS, GCP, Azure, VMWare, Baremetal)
- Off the shelf chaos-integrated monitoring dashboards for application chaos categories
- Support for user defined chaos experiment result definition
- Increased fault injection types (IOChaos, HTTPChaos, JVMChaos)
- Special Interest Groups (SIGs) around specific areas in the project to take the roadmap forward
