10 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser. 11 | 12 | The page will reload if you make edits.
13 | You will also see any lint errors in the console. 14 | 15 | ### `npm test` 16 | 17 | Launches the test runner in the interactive watch mode.
18 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information. 19 | 20 | ### `npm run build` 21 | 22 | Builds the app for production to the `build` folder.
23 | It correctly bundles React in production mode and optimizes the build for the best performance. 24 | 25 | The build is minified and the filenames include the hashes.
26 | Your app is ready to be deployed! 27 | 28 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information. 29 | 30 | ### `npm run eject` 31 | 32 | **Note: this is a one-way operation. Once you `eject`, you can’t go back!** 33 | 34 | If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project. 35 | 36 | Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own. 37 | 38 | You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it. 39 | 40 | ## Learn More 41 | 42 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started). 43 | 44 | To learn React, check out the [React documentation](https://reactjs.org/). 45 | 46 | ### Code Splitting 47 | 48 | This section has moved here: https://facebook.github.io/create-react-app/docs/code-splitting 49 | 50 | ### Analyzing the Bundle Size 51 | 52 | This section has moved here: https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size 53 | 54 | ### Making a Progressive Web App 55 | 56 | This section has moved here: https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app 57 | 58 | ### Advanced Configuration 59 | 60 | This section has moved here: https://facebook.github.io/create-react-app/docs/advanced-configuration 61 | 62 | ### Deployment 63 | 64 | This section has moved here: https://facebook.github.io/create-react-app/docs/deployment 65 | 66 | ### `npm run build` fails to minify 67 | 68 | This section has moved here: https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify 69 | -------------------------------------------------------------------------------- /aws/cloud-formation-s3.yml: -------------------------------------------------------------------------------- 1 | AWSTemplateFormatVersion: 2010-09-09 2 | Parameters: 3 | chaosLambdaS3Bucket: 4 | Description: Name of the S3 lambda bucket 5 | Type: String 6 | chaosDomain: 7 | Description: Name of the domain to host on i.e example.com 8 | Type: String 9 | Mappings: 10 | RegionMap: 11 | us-east-1: 12 | S3hostedzoneID: Z3AQBSTGFYJSTF 13 | websiteendpoint: s3-website-us-east-1.amazonaws.com 14 | us-west-1: 15 | S3hostedzoneID: Z2F56UZL2M1ACD 16 | websiteendpoint: s3-website-us-west-1.amazonaws.com 17 | us-west-2: 18 | S3hostedzoneID: Z3BJ6K6RIION7M 19 | websiteendpoint: s3-website-us-west-2.amazonaws.com 20 | eu-west-1: 21 | S3hostedzoneID: Z1BKCTXD74EZPE 22 | websiteendpoint: s3-website-eu-west-1.amazonaws.com 23 | ap-southeast-1: 24 | S3hostedzoneID: Z3O0J2DXBE1FTB 25 | websiteendpoint: s3-website-ap-southeast-1.amazonaws.com 26 | ap-southeast-2: 27 | S3hostedzoneID: Z1WCIGYICN2BYD 28 | websiteendpoint: s3-website-ap-southeast-2.amazonaws.com 29 | ap-northeast-1: 30 | S3hostedzoneID: Z2M4EHUR26P7ZW 31 | websiteendpoint: s3-website-ap-northeast-1.amazonaws.com 32 | sa-east-1: 33 | S3hostedzoneID: Z31GFT0UA1I2HV 34 | websiteendpoint: s3-website-sa-east-1.amazonaws.com 35 | us-east-2: 36 | S3hostedzoneID: Z2O1EMRO9K5GLX 37 | websiteendpoint: s3-website.us-east-2.amazonaws.com 38 | Resources: 39 | S3LambdaBucket: 40 | Type: AWS::S3::Bucket 41 | Properties: 42 | BucketName: 43 | # refer to chaos-website-deployer code to work out how this param is passed 44 | Ref: chaosLambdaS3Bucket 45 | PublicAccessBlockConfiguration: 46 | BlockPublicAcls: true 47 | BlockPublicPolicy: true 48 | IgnorePublicAcls: true 49 | RestrictPublicBuckets: true 50 | RootBucket: 51 | Type: AWS::S3::Bucket 52 | Properties: 53 | BucketName: 54 | Ref: chaosDomain 55 | AccessControl: PublicRead 56 | WebsiteConfiguration: 57 | IndexDocument: index.html 58 | ErrorDocument: 404.html 59 | WWWBucket: 60 | Type: AWS::S3::Bucket 61 | Properties: 62 | BucketName: !Sub 63 | - www.${Domain} 64 | - Domain: !Ref chaosDomain 65 | AccessControl: BucketOwnerFullControl 66 | WebsiteConfiguration: 67 | RedirectAllRequestsTo: 68 | HostName: !Ref RootBucket 69 | myDNS: 70 | Type: AWS::Route53::RecordSetGroup 71 | Properties: 72 | HostedZoneName: !Sub 73 | - ${Domain}. 74 | - Domain: !Ref chaosDomain 75 | Comment: Zone apex alias. 76 | RecordSets: 77 | - 78 | Name: !Sub 79 | - www.${Domain} 80 | - Domain: !Ref chaosDomain 81 | Type: A 82 | AliasTarget: 83 | HostedZoneId: !FindInMap [ RegionMap, !Ref 'AWS::Region', S3hostedzoneID] 84 | DNSName: !FindInMap [ RegionMap, !Ref 'AWS::Region', websiteendpoint] 85 | - 86 | Name: !Ref chaosDomain 87 | Type: A 88 | AliasTarget: 89 | HostedZoneId: !FindInMap [ RegionMap, !Ref 'AWS::Region', S3hostedzoneID] 90 | DNSName: !FindInMap [ RegionMap, !Ref 'AWS::Region', websiteendpoint] 91 | 92 | Outputs: 93 | WebsiteURL: 94 | Value: !GetAtt RootBucket.WebsiteURL 95 | Description: URL for website hosted on S3 -------------------------------------------------------------------------------- /client/scss/_thisisus.scss: -------------------------------------------------------------------------------- 1 | html, 2 | body { 3 | padding: 0;

ChaosQoaLa can be used to add latency, and/or knock out specific data sections of a GraphQL server's responses. The extent of the chaos effect can be controlled via a "blast radius" configuration parameter so only a specified portion of responses are affected. There are three fundamental components. The first component is a piece of named middleware you will integrate into your GraphQL server implementation. This "**Agent**" sits in the server and will cause chaos on demand when it is sent instructions to do so. The "**Controller**" is a CLI tool which is installed on a test user's personal machine/VM and can be used to configure, run, and stop a chaos experiment. The "**Site**" (www.chaosqoala.io) can be used to upload results files 3 | generated by the Controller for visualization. 4 | 5 | ## **Supported GraphQL Servers** 6 | 7 | - Express GraphQL 8 | - Apollo Server Express 9 | 10 | ## **Installation** 11 | 12 | **Agent** 13 | 14 | 15 | # npm install chaosqoaloa-agent 16 | Once installed in your server's codebase the agent can be integrated in 3 lines of code (between the koalas). 17 | 18 | > Express Graph QL example: 19 | 20 | ![enter image description here](https://cqlimage.s3-us-west-1.amazonaws.com/Express+Server.png) 21 | 22 | > Apollo Server Express example: 23 | 24 | ![enter image description here](https://cqlimage.s3-us-west-1.amazonaws.com/Apollo+Server.png) 25 | 26 | 27 | 28 | **Controller** 29 | 30 | 31 | Install on each test users' machine. 32 | 33 | # npm install chaosqoaloa 34 | 35 | 36 | ## **Steady State Integration** 37 | A key metric in chaos engineering experiments is 'steady state'. Steady state is a measure of how well a system is performing. Different systems will be measured by different metrics, for example Netflix uses 'number of plays' to evaluate how well their systems or service is performing. ChaosQoaLa requires access to an endpoint that can be called when the chaos experiment starts, and again when the experiment ends. The end point must be stateful and respond to the stop invocation with steady state data points for the duration of the test run. The results are expected to be in a JSON array in the format: 38 | 39 | [ { "timeOfResult": "2019-09-10T04:34:22.290Z", "result": 97 }, 40 | { "timeOfResult": "2019-09-10T04:34:22.390Z", "result": 79 }, 41 | {.... ] 42 | 43 | ## **Using ChaosQoaLa** 44 | 45 | **Configuring a test run** 46 | 47 | 48 | To configure a test run enter the following command on a user's machine with the Controller installed 49 | 50 | # chaosqoala configure 51 | The CLI tool will display a series of questions: 52 | 53 | Please enter the URI of the Socket.io port over which Chaos will be sent and received 54 | By default the Agent listens on port 1025 of the GraphQL server in which it has been installed. Enter the fully qualified path of port 1025 on the GraphQL server, for example https://gql.example.com:1025 55 | 56 | Please enter the URI of GraphQL service 57 | Enter the fully qualified path of the GraphQL server, for example https://gql.example.com 58 | 59 | Please enter your desired blast radius 60 | Enter a number between 0.0 and 1.0 to represent the % of responses that will be affected by chaos, for example a figure of 0.33 will result in 33% of responses from the server being subjected to failure injection. 61 | 62 | Please enter the amount of time you would like your data to be delayed (in milliseconds) 63 | Enter the number of milliseconds of latency to introduce to responses chosen for failure injection, use a value of zero in order to switch off latency injection. 64 | 65 | Please enter how long you would like the ChaosQoala to run (in minutes). 66 | Enter the duration of the test run in minutes. Test runs can be terminated at any point by pressing any key in the Controller CLI during test execution. 67 | 68 | Please enter the steady state start URL 69 | 70 | Enter the fully qualified URI for the steady state service you have implemented, this URI will be invoked when the chaos experiment is started. For example: https://api.example.com/steadystate/start 71 | 72 | Please enter the steady state start HTTP verb 73 | Enter the http verb used to invoke the steady state start route, GET/POST/PUT etc. 74 | 75 | Please enter the steady state stop URL 76 | Enter the fully qualified URI for the steady state service you have implemented, this URI will invoked when the chaos experiment is stopped. For example: https://api.example.com/steadystate/stop 77 | 78 | Please enter the steady state stop HTTP verb 79 | Enter the http verb used to invoke the steady state stop route, eg GET/POST/PUT etc. 80 | 81 | **Configuring query knockout** 82 | 83 | 84 | Once configure has been ran the Controller will write the configuration to its package.json. The Controller also inspects the GraphQL end point entered and extracts a list of available queries. To knock out data for a GraphQL query during an experiment just toggle the booleans in the affectedQueries object of the package.json: 85 | 86 | "chaosConfig": { 87 | . . . 88 | "affectedQueries": { 89 | "dontKnockMeOut": false, 90 | "knockMeOut": true 91 | }, 92 | }, 93 | **Running an experiment** 94 | 95 | 96 | Once you are happy with the configuration the experiment can be started with the start command 97 | 98 | # chaosqoala start 99 | When the experiment ends a results file will be generated on the machine the Controller is running on - this file (*timestamp*_results.json) can be visualized on the ChaosQoaLa site via the upload link. 100 | ## **License** 101 | This project is licensed under the MIT License. 102 | 103 | ## **Authors** 104 | - Jacob Ory: github.com/jakeory 105 |
