**Introduction**
|
||||
|
||||
Litmus chaos hub is a place where the chaos engineering community members publish their chaos experiments. A set of related chaos experiments are bundled into a `Chaos Chart`. Chaos Charts are classified into the following categories.
|
||||
|
||||
- [Generic Chaos](#generic-chaos)
|
||||
- [Application Chaos](#application-chaos)
|
||||
- [Platform Chaos](#platform-chaos)
|
||||
|
||||
|
||||
|
||||
### Generic Chaos
|
||||
|
||||
Chaos actions that apply to generic Kubernetes resources are classified into this category. Following chaos experiments are supported under Generic Chaos Chart
|
||||
|
||||
| Experiment name | Description | User guide link |
|
||||
| ----------- | ----------------------------------------- | --------------------------------------------------------- |
|
||||
| Container Kill | Kill one container in the application pod | [container-kill](container-kill.md)|
|
||||
| Pod Delete | Fail the application pod | [pod-delete](pod-delete.md) |
|
||||
| Pod Network Latency | Experiment to inject network latency to the POD | [pod-network-latency](pod-network-latency.md) |
|
||||
| Pod Network Loss | Experiment to inject network loss to the POD | [pod-network-loss](pod-network-loss.md) |
|
||||
| CPU Hog | Exhaust CPU resources on the Kubernetes Node | [cpu-hog](cpu-hog.md) |
|
||||
| Disk Fill | Fillup Ephemeral Storage of a Resource | [disk-fill](disk-fill.md) |
|
||||
| Disk Loss | External disk loss from the node | [disk-loss](disk-loss.md)|
|
||||
| Node Drain| Drain the node where application pod is scheduled | [node-drain](node-drain.md) |
|
||||
| Pod CPU Hog | Consume CPU resources on the application container | [pod-cpu-hog](pod-cpu-hog.md) |
|
||||
| Pod Network Corruption | Inject Network Packet Corruption Into Application Pod |[pod-network-corruption](pod-network-corruption.md) |
|
||||
|
||||
### Application Chaos
|
||||
|
||||
While Chaos Experiments under the Generic category offer the ability to induce chaos into Kubernetes resources, it is difficult to analyze and conclude if the chaos induced found a weakness in a given application. The application specific chaos experiments are built with some checks on *pre-conditions* and some expected outcomes after the chaos injection. The result of the chaos experiment is determined by matching the outcome with the expected outcome.
|
||||
|
||||
<div class="danger">
|
||||
<strong>NOTE:</strong> If the result of the chaos experiment is `pass`, it means that the application is resilient to that chaos.
|
||||
</div>
|
||||
|
||||
|
||||
#### Benefits of contributing an application chaos experiment
|
||||
|
||||
Application developers write negative tests in their CI pipelines to test the resiliency of the applications. These negative can be converted into Litmus Chaos Experiments and contributed to ChaosHub, so that the users of the application can use them in staging/pre-production/production environments to check the resilience. Application environments vary considerably from where they are tested (CI pipelines) to where they are deployed (Production). Hence, running the same chaos tests in the user's environment will help determine the weaknesses of the deployment and fixing such weaknesses leads to increased resilience.

| CoreDns | CoreDNS is a fast and flexible DNS server that chains plugins | [coredns-pod-delete](coredns-pod-delete.md)|
|
||||
|
||||
### Platform Chaos
|
||||
|
||||
Chaos experiments that inject chaos into the platform resources of Kubernetes are classified into this category. Management of platform resources vary significantly from each other, Chaos Charts may be maintained separately for each platform (For example, AWS, GCP, Azure, etc)
|
||||
|
||||
Following Platform Chaos experiments are available on ChaosHub

Litmus provides a way to use any chaos library or a tool to inject chaos. The chaos tool to be compatible with Litmus should satisfy the following requirements:
|
||||
|
||||
- Should be available as a Docker Image
|
||||
- Should take configuration through a `config-map`
|
||||
|
||||
The `plugins` or `chaos-libraries` host the core logic to inject chaos.
|
||||
|
||||
These plugins are hosted at https://github.com/litmuschaos/litmus-ansible/tree/master/chaoslib
|
||||
|
||||
Litmus project has integration into the following chaos-libraries.

|

|
||||
### What is Adminstator Mode?
|
||||
|
||||
Admin mode is one of the ways the chaos orchestration is set up in Litmus, wherein all chaos resources (i.e., install time resources like the operator, chaosexperiment CRs, chaosServiceAccount/rbac and runtime resources like chaosengine, chaos-runner, experiment jobs & chaosresults) are setup in a single admin namespace (typically, litmus). In other words, centralized administration of chaos.
|
||||
This feature is aimed at making the SRE/Cluster Admins life easier by doing away with setting up chaos pre-requisites on a per namespace basis (which may be more relevant in an autonomous/self-service cluster sharing model in dev environments).
|
||||
This mode typically needs a "wider" & "stronger" ClusterRole, albeit one that is still just a superset of the individual experiment permissions. In this mode, the applications in their respective namespaces are subjected to chaos while the chaos job runs elsewhere, i.e., admin namespace.
|
||||
|
||||
### How to use Adminstator Mode?
|
||||
|
||||
In order to use Admin Mode, you just have to create a ServiceAccount in the *admin* or so called *chaos* namespace (`litmus` itself can be used), which is tied to a ClusterRole that has the permissions to perform operations on Kubernetes resources involved in the selected experiments across namespaces.
|
||||
Provide this ServiceAccount in ChaosEngine's .spec.chaosServiceAccount.
|
||||
|
||||
### Example
|
||||
|
||||
#### Prepare RBAC Manifest
|
||||
|
||||
Here is an RBAC definition, which in essence is a superset of individual experiments RBAC that has the permissions to run all chaos experiments across different namespaces.

|
||||
### Create the ChaosEngine Resource
|
||||
|
||||
- Create the ChaosEngine manifest prepared in the previous step to trigger the Chaos.
|
||||
|
||||
`kubectl apply -f chaosengine.yml`
|
||||
|
||||
### Watch Chaos Engine
|
||||
|
||||
- Describe Chaos Engine for chaos steps.
|
||||
|
||||
`kubectl describe chaosengine nginx-chaos -n litmus`
|
||||
|
||||
### Watch Chaos progress
|
||||
|
||||
- View pod terminations & recovery by setting up a watch on the pods in the application namespace
|
||||
|
||||
`watch -n 1 kubectl get pods -n default`
|
||||
|
||||
### Check Chaos Experiment Result
|
||||
|
||||
- Check whether the application is resilient to the pod failure, once the experiment (job) is completed. The ChaosResult resource name is derived like this: `<ChaosEngine-Name>-<ChaosExperiment-Name>`.
|
||||
|
||||
`kubectl describe chaosresult nginx-chaos-pod-delete -n litmus`

### Application Chaos
|
||||
|
||||
While Chaos Experiments under the Generic category offer the ability to induce chaos into Kubernetes resources, it is difficult to analyze and conclude if the chaos induced found a weakness in a given application. The application specific chaos experiments are built with some checks on *pre-conditions* and some expected outcomes after the chaos injection. The result of the chaos experiment is determined by matching the outcome with the expected outcome.
|
||||
|
||||
<div class="danger">
|
||||
<strong>NOTE:</strong> If the result of the chaos experiment is `pass`, it means that the application is resilient to that chaos.
|
||||
</div>
|
||||
|
||||
|
||||
#### Benefits of contributing an application chaos experiment
|
||||
|
||||
Application developers write negative tests in their CI pipelines to test the resiliency of the applications. These negative can be converted into Litmus Chaos Experiments and contributed to ChaosHub, so that the users of the application can use them in staging/pre-production/production environments to check the resilience. Application environments vary considerably from where they are tested (CI pipelines) to where they are deployed (Production). Hence, running the same chaos tests in the user's environment will help determine the weaknesses of the deployment and fixing such weaknesses leads to increased resilience.

### Platform Chaos
|
||||
|
||||
Chaos experiments that inject chaos into the platform resources of Kubernetes are classified into this category. Management of platform resources vary significantly from each other, Chaos Charts may be maintained separately for each platform (For example, AWS, GCP, Azure, etc)
|
||||
|
||||
Following Platform Chaos experiments are available on ChaosHub

Litmus provides a way to use any chaos library or a tool to inject chaos. The chaos tool to be compatible with Litmus should satisfy the following requirements:
|
||||
|
||||
- Should be available as a Docker Image
|
||||
- Should take configuration through a `config-map`
|
||||
|
||||
The `plugins` or `chaos-libraries` host the core logic to inject chaos.
|
||||
|
||||
These plugins are hosted at https://github.com/litmuschaos/litmus-ansible/tree/master/chaoslib
|
||||
|
||||
Litmus project has integration into the following chaos-libraries.

**Introduction**
|
||||
|
||||
Litmus chaos hub is a place where the Chaos Engineering community members publish their chaos experiments. A set of related chaos experiments are bundled into a `Chaos Chart`. Chaos Charts are classified into the following categories.
|
||||
|
||||
- [Generic Chaos](#generic-chaos)
|
||||
- [Application Chaos](#application-chaos)
|
||||
- [Platform Chaos](#platform-chaos)
|
||||
|
||||
|
||||
|
||||
### Generic Chaos

### Application Chaos
|
||||
|
||||
While Chaos Experiments under the Generic category offer the ability to induce chaos into Kubernetes resources, it is difficult to analyze and conclude if the chaos induced found a weakness in a given application. The application specific chaos experiments are built with some checks on *pre-conditions* and some expected outcomes after the chaos injection. The result of the chaos experiment is determined by matching the outcome with the expected outcome.
|
||||
|
||||
<div class="danger">
|
||||
<strong>NOTE:</strong> If the result of the chaos experiment is `pass`, it means that the application is resilient to that chaos.
|
||||
</div>
|
||||
|
||||
|
||||
#### Benefits of contributing an application chaos experiment
|
||||
|
||||
Application developers write negative tests in their CI pipelines to test the resiliency of the applications. These negative can be converted into Litmus Chaos Experiments and contributed to ChaosHub, so that the users of the application can use them in staging/pre-production/production environments to check the resilience. Application environments vary considerably from where they are tested (CI pipelines) to where they are deployed (Production). Hence, running the same chaos tests in the user's environment will help determine the weaknesses of the deployment and fixing such weaknesses leads to increased resilience.

|
||||
|
||||
**Introduction**
|
||||
|
||||
Litmus chaos hub is a place where the chaos engineering community members publish their chaos experiments. A set of related chaos experiments are bundled into a `Chaos Chart`. Chaos Charts are classified into the following categories.
|
||||
|
||||
- [Generic Chaos](#generic-chaos)
|
||||
- [Application Chaos](#application-chaos)
|
||||
- [Platform Chaos](#platform-chaos)
|
||||
|
||||
### Generic Chaos
|
||||
|
||||
Chaos actions that apply to generic Kubernetes resources are classified into this category. Following chaos experiments are supported under Generic Chaos Chart
|
||||
|
||||
| Experiment name | Description | User guide link |
|
||||
| ---------------------- | ----------------------------------------------------- | --------------------------------------------------- |
|
||||
| Container Kill | Kill one container in the application pod | [container-kill](container-kill.md) |
|
||||
| Pod Delete | Fail the application pod | [pod-delete](pod-delete.md) |
|
||||
| Pod Network Latency | Experiment to inject network latency to the POD | [pod-network-latency](pod-network-latency.md) |
|
||||
| Pod Network Loss | Experiment to inject network loss to the POD | [pod-network-loss](pod-network-loss.md) |
|
||||
| CPU Hog | Exhaust CPU resources on the Kubernetes Node | [cpu-hog](cpu-hog.md) |
|
||||
| Disk Fill | Fillup Ephemeral Storage of a Resource | [disk-fill](disk-fill.md) |
|
||||
| Disk Loss | External disk loss from the node | [disk-loss](disk-loss.md) |
|
||||
| Node Drain | Drain the node where application pod is scheduled | [node-drain](node-drain.md) |
|
||||
| Pod CPU Hog | Consume CPU resources on the application container | [pod-cpu-hog](pod-cpu-hog.md) |
|
||||
| Pod Network Corruption | Inject Network Packet Corruption Into Application Pod | [pod-network-corruption](pod-network-corruption.md) |
|
||||
|
||||
### Application Chaos
|
||||
|
||||
While Chaos Experiments under the Generic category offer the ability to induce chaos into Kubernetes resources, it is difficult to analyze and conclude if the chaos induced found a weakness in a given application. The application specific chaos experiments are built with some checks on _pre-conditions_ and some expected outcomes after the chaos injection. The result of the chaos experiment is determined by matching the outcome with the expected outcome.
|
||||
|
||||
<div class="danger">
|
||||
<strong>NOTE:</strong> If the result of the chaos experiment is `pass`, it means that the application is resilient to that chaos.
|
||||
</div>
|
||||
|
||||
#### Benefits of contributing an application chaos experiment
|
||||
|
||||
Application developers write negative tests in their CI pipelines to test the resiliency of the applications. These negative can be converted into Litmus Chaos Experiments and contributed to ChaosHub, so that the users of the application can use them in staging/pre-production/production environments to check the resilience. Application environments vary considerably from where they are tested (CI pipelines) to where they are deployed (Production). Hence, running the same chaos tests in the user's environment will help determine the weaknesses of the deployment and fixing such weaknesses leads to increased resilience.
|
||||
|
||||
Following Application Chaos experiments are available on ChaosHub
|
||||
|
||||
| Application | Description | Chaos Experiments |
|
||||
| ----------- | ------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

|
||||
| Kafka | Open-source stream processing software | [kafka-broker-pod-failure](kafka-broker-pod-failure.md)<br/>[kafka-broker-disk-failure](kafka-broker-disk-failure.md)<br/> |
|
||||
| CoreDns | CoreDNS is a fast and flexible DNS server that chains plugins | [coredns-pod-delete](coredns-pod-delete.md) |
|
||||
|
||||
### Platform Chaos
|
||||
|
||||
Chaos experiments that inject chaos into the platform resources of Kubernetes are classified into this category. Management of platform resources vary significantly from each other, Chaos Charts may be maintained separately for each platform (For example, AWS, GCP, Azure, etc)
|
||||
|
||||
Following Platform Chaos experiments are available on ChaosHub
|
||||
|
||||
| Platform | Description | Chaos Experiments |
|
||||
| -------- | ------------------------------------------- | ----------------- |
|
||||
| AWS | Amazon Web Services platform. Includes EKS. | None |
|
||||
| GCP | Google Cloud Platform. Includes GKE. | None |
|
||||
| Azure | Microsoft Azure platform. Includes AKS. | None |

## Prerequisites
|
||||
|
||||
- Ensure that the Litmus Chaos Operator is running by executing `kubectl get pods` in operator namespace (typically, `litmus`). If not, install from [here](https://raw.githubusercontent.com/litmuschaos/pages/master/docs/litmus-operator-latest.yaml)
|
||||
- Ensure that the `disk-loss` experiment resource is available in the cluster by `kubectl get chaosexperiments` in the desired namespace. If not, install from <a href="https://hub.litmuschaos.io/charts/generic/experiments/disk-loss" target="_blank">here</a>
|

Litmus provides a way to use any chaos library or a tool to inject chaos. The chaos tool to be compatible with Litmus should satisfy the following requirements:
|
||||
|
||||
- Should be available as a Docker Image
|
||||
- Should take configuration through a `config-map`
|
||||
|
||||
The `plugins` or `chaos-libraries` host the core logic to inject chaos.
|
||||
|
||||
These plugins are hosted at https://github.com/litmuschaos/litmus-ansible/tree/master/chaoslib
|
||||
|
||||
Litmus project has integration into the following chaos-libraries.

|
||||
**Introduction**
|
||||
|
||||
Litmus chaos hub is a place where the chaos engineering community members publish their chaos experiments. A set of related chaos experiments are bundled into a `Chaos Chart`. Chaos Charts are classified into the following categories.
|
||||
|
||||
- [Generic Chaos](#generic-chaos)
|
||||
- [Application Chaos](#application-chaos)
|
||||
- [Platform Chaos](#platform-chaos)
|
||||
|
||||
### Generic Chaos
|
||||
|
||||
Chaos actions that apply to generic Kubernetes resources are classified into this category. Following chaos experiments are supported under Generic Chaos Chart
|
||||
|
||||
| Experiment name | Description | User guide link |
|
||||
| ---------------------- | ----------------------------------------------------- | --------------------------------------------------- |
|
||||
| Container Kill | Kill one container in the application pod | [container-kill](container-kill.md) |
|
||||
| Pod Delete | Fail the application pod | [pod-delete](pod-delete.md) |
|
||||
| Pod Network Latency | Experiment to inject network latency to the POD | [pod-network-latency](pod-network-latency.md) |
|
||||
| Pod Network Loss | Experiment to inject network loss to the POD | [pod-network-loss](pod-network-loss.md) |
|
||||
| Node CPU Hog | Exhaust CPU resources on the Kubernetes Node | [node-cpu-hog](node-cpu-hog.md) |
|
||||
| Disk Fill | Fillup Ephemeral Storage of a Resource | [disk-fill](disk-fill.md) |
|
||||
| Disk Loss | External disk loss from the node | [disk-loss](disk-loss.md) |
|
||||
| Node Drain | Drain the node where application pod is scheduled | [node-drain](node-drain.md) |
|
||||
| Pod CPU Hog | Consume CPU resources on the application container | [pod-cpu-hog](pod-cpu-hog.md) |
|
||||
| Pod Network Corruption | Inject Network Packet Corruption Into Application Pod | [pod-network-corruption](pod-network-corruption.md) |
|
||||
|
||||
### Application Chaos
|
||||
|
||||
While Chaos Experiments under the Generic category offer the ability to induce chaos into Kubernetes resources, it is difficult to analyze and conclude if the chaos induced found a weakness in a given application. The application specific chaos experiments are built with some checks on _pre-conditions_ and some expected outcomes after the chaos injection. The result of the chaos experiment is determined by matching the outcome with the expected outcome.
|
||||
|
||||
<div class="danger">
|
||||
<strong>NOTE:</strong> If the result of the chaos experiment is `pass`, it means that the application is resilient to that chaos.
|
||||
</div>
|
||||
|
||||
#### Benefits of contributing an application chaos experiment
|
||||
|
||||
Application developers write negative tests in their CI pipelines to test the resiliency of the applications. These negative can be converted into Litmus Chaos Experiments and contributed to ChaosHub, so that the users of the application can use them in staging/pre-production/production environments to check the resilience. Application environments vary considerably from where they are tested (CI pipelines) to where they are deployed (Production). Hence, running the same chaos tests in the user's environment will help determine the weaknesses of the deployment and fixing such weaknesses leads to increased resilience.
|
||||
|
||||
Following Application Chaos experiments are available on ChaosHub
|
||||
|
||||
| Application | Description | Chaos Experiments |
|
||||
| ----------- | ------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| OpenEBS | Container Attached Storage for Kubernetes | [openebs-pool-pod-failure](openebs-pool-pod-failure.md)<br/>[openebs-pool-container-failure](openebs-pool-container-failure.md)<br/>[openebs-target-pod-failure](openebs-target-pod-failure.md)<br/>[openebs-target-container-failure](openebs-target-container-failure.md)<br/>[openebs-target-network-delay](openebs-target-network-delay.md)<br/>[openebs-target-network-loss](openebs-target-network-loss.md) |
|
||||
| Kafka | Open-source stream processing software | [kafka-broker-pod-failure](kafka-broker-pod-failure.md)<br/>[kafka-broker-disk-failure](kafka-broker-disk-failure.md)<br/> |
|
||||
| CoreDns | CoreDNS is a fast and flexible DNS server that chains plugins | [coredns-pod-delete](coredns-pod-delete.md) |
|
||||
|
||||
### Platform Chaos
|
||||
|
||||
Chaos experiments that inject chaos into the platform resources of Kubernetes are classified into this category. Management of platform resources vary significantly from each other, Chaos Charts may be maintained separately for each platform (For example, AWS, GCP, Azure, etc)
|
||||
|
||||
Following Platform Chaos experiments are available on ChaosHub
|
||||
|
||||
| Platform | Description | Chaos Experiments |
|
||||
| -------- | ------------------------------------------- | ----------------- |
|
||||
| AWS | Amazon Web Services platform. Includes EKS. | None |
|
||||
| GCP | Google Cloud Platform. Includes GKE. | None |
|
||||
| Azure | Microsoft Azure platform. Includes AKS. | None |

| Type | Description | Tested K8s Platform |
|
||||
| ------- | -------------------------------------------- | ------------------- |
|
||||
| Generic | Exhaust CPU resources on the Kubernetes Node | GKE |
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Ensure that the Litmus Chaos Operator is running by executing `kubectl get pods` in operator namespace (typically, `litmus`). If not, install from [here](https://raw.githubusercontent.com/litmuschaos/pages/master/docs/litmus-operator-latest.yaml)
|
||||
- Ensure that the `cpu-hog` experiment resource is available in the cluster by executing `kubectl get chaosexperiments` in the desired namespace. If not, install from [here](https://hub.litmuschaos.io/charts/generic/experiments/cpu-hog)
|
||||
- There should be administrative access to the platform on which the Kubernetes cluster is hosted, as the recovery of the affected node could be manual. For example, gcloud access to the GKE project
|
||||
|
||||
## Entry Criteria
|
||||
|
||||
- Application pods are healthy on the respective Nodes before chaos injection
|
||||
|
||||
## Exit Criteria
|
||||
|
||||
- Application pods may or may not be healthy post chaos injection
|
||||
|
||||
## Details
|
||||
|
||||
- This experiment causes CPU resource exhaustion on the Kubernetes node. The experiment aims to verify resiliency of applications whose replicas may be evicted on account on nodes turning unschedulable (Not Ready) due to lack of CPU resources.
|
||||
- The CPU chaos is injected using a daemonset running the linux stress tool (a workload generator). The chaos is effected for a period equalling the TOTAL_CHAOS_DURATION
|
||||
- Application implies services. Can be reframed as:
|
||||
Tests application resiliency upon replica evictions caused due to lack of CPU resources
|
||||
|
||||
## Integrations
|
||||
|
||||
- CPU Hog can be effected using the chaos library: `litmus`
|
||||
- The desired chaos library can be selected by setting `litmus` as value for the env variable `LIB`
|
||||
|
||||
## Steps to Execute the Chaos Experiment
|
||||
|
||||
- This Chaos Experiment can be triggered by creating a ChaosEngine resource on the cluster. To understand the values to provide in a ChaosEngine specification, refer [Getting Started](getstarted.md/#prepare-chaosengine)
|
||||
|
||||
- Follow the steps in the sections below to create the chaosServiceAccount, prepare the ChaosEngine & execute the experiment.
|
||||
|
||||
### Prepare chaosServiceAccount
|
||||
|
||||

|
||||
```
|
||||
|
||||
### Create the ChaosEngine Resource
|
||||
|
||||
- Create the ChaosEngine manifest prepared in the previous step to trigger the Chaos.
|
||||
|
||||
`kubectl apply -f chaosengine.yml`
|
||||
|
||||
### Watch Chaos progress
|
||||
|
||||
- Setting up a watch of the CPU consumed by nodes in the Kubernetes Cluster
|
||||
|
||||
`watch kubectl top nodes`
|
||||
|
||||
### Check Chaos Experiment Result
|
||||
|
||||
- Check whether the application is resilient to the CPU hog, once the experiment (job) is completed. The ChaosResult resource name is derived like this: `<ChaosEngine-Name>-<ChaosExperiment-Name>`.
|
||||
|
||||
`kubectl describe chaosresult nginx-chaos-cpu-hog -n <application-namespace>`
|
||||
|
||||

This page serves as a guide to develop either a new Chaos Chart or a new experiment in a Chaos Chart which are published at <a href="https://hub.litmuschaos.io" target="_blank">ChaosHub</a>.
|
||||
|
||||
Below are some key points to remember before understanding how to write a new chart or an experiment.
|
||||
|
||||
> Chaos Charts repository : https://github.com/litmuschaos/chaos-charts
|
||||
>
|
||||
> Litmusbooks repository : https://github.com/litmuschaos/litmus-ansible/tree/master/experiments
|
||||
>
|
||||
> Website rendering code repository: https://github.com/litmuschaos/charthub.litmuschaos.io
|
||||
|
||||
The experiments & chaos libraries are typically written in Ansible, though not mandatory. Ensure that
|
||||
the experiments can be executed in a container & can read/update the litmuschaos custom resources. For example,
|
||||
if you are writing an experiment in Go, use this [clientset](https://github.com/litmuschaos/chaos-operator/tree/master/pkg/client)
|
||||
|
||||
<hr/>
|
||||
|
||||
## Glossary
|
||||
|
||||
### Chaos Chart
|
||||
|
||||
A group of Choas Experiments put together in a YAML file. Each group or chart has a metadata manifest called `ChartServiceVersion`
|
||||
that holds data such as `ChartVersion`, `Contributors`, `Description`, `links` etc.., This metadata is rendered on the ChartHub.
|
||||
A chaos chart also consists of a `package` manifest that is an index of available experiments in the chart.
|
||||
|
||||
Here is an example of the [ChartServiceVersion](https://github.com/litmuschaos/chaos-charts/blob/master/charts/generic/generic.chartserviceversion.yaml) & [package](https://github.com/litmuschaos/chaos-charts/blob/master/charts/generic/generic.package.yaml) manifests of the generic chaos chart.
|
||||
|
||||
### Chaos Experiment
|
||||
|
||||
ChaosExperiment is a CRD that specifies the nature of a Chaos Experiment. The YAML file that constitutes a Chaos Experiment CR
|
||||
is stored under a Chaos Chart of ChaosHub and typically consists of low-level chaos parameters specific to that experiment, set
|
||||
to their default values.
|
||||
|
||||
Here is an example chaos experiment CR for a [pod-delete](https://github.com/litmuschaos/chaos-charts/blob/master/charts/generic/pod-delete/experiment.yaml) experiment
|
||||
|
||||
### Litmus Book
|
||||
|
||||
Litmus book is an `ansible` playbook that encompasses the logic of pre-checks, chaos-injection, post-checks, and result-updates.
|
||||
Typically, these are accompanied by a Kubernetes job that can execute the respective playbook.
|
||||
|
||||
Here is an example of the litmus book for the [pod-delete](https://github.com/litmuschaos/litmus-ansible/tree/master/experiments/generic/pod_delete) experiment.
|
||||
|
||||
### Chaos functions
|
||||
|
||||
The `ansible` business logic inside Litmus books can make use of readily available chaos functions. The chaos functions are available as `task-files` which are wrapped in one of the chaos libraries. See [plugins](plugins.md) for more details.
|
||||

Litmus provides a way to use any chaos library or a tool to inject chaos. The chaos tool to be compatible with Litmus should satisfy the following requirements:
|
||||
|
||||
- Should be available as a Docker Image
|
||||
- Should take configuration through a `config-map`
|
||||
|
||||
The `plugins` or `chaos-libraries` host the core logic to inject chaos.
|
||||
|
||||
These plugins are hosted at https://github.com/litmuschaos/litmus-ansible/tree/master/chaoslib
|
||||
|
||||
Litmus project has integration into the following chaos-libraries.
