Main app shows a giant sign that flashes in various random 4 | colors. Those colors come a Kubernetes powered microservice. If the service 5 | goes down, the sign turns red. Your goal is to try and knock the service down 6 | by killing the Kubernetes pods that run the service. You can do that by 7 | whacking the pods wich are respresented as moles. 8 | 9 | ![Whack-a-pod Screenshot](screenshots/game.png "Screenshot") 10 | 11 | There is also a less busy verison of the game available at /next.html. This 12 | version has an advanced mode that allows someone to do a more visual 13 | explanation of the mechanics. 14 | 15 | ![Next Screenshot](screenshots/next.png "Next Version") 16 | 17 | The advanced version allows you to track the pod that is serving the color 18 | service and to simulate creating and destroying nodes. 19 | 20 | ![Advanced Screenshot](screenshots/advanced.png "Advanced Version") 21 | 22 | ## Getting Started 23 | 24 | The current directions assume you are using Google Cloud Platform to take 25 | advantage of Container Engine to build a manage your Kubernetes cluster. There 26 | is nothing preventing this app from *running* on a Kubernetes cluster hosted 27 | elsewhere, but the directions for setup assume Container Engine. If there is 28 | significant interest in these directions, I'll be happy to publish them (or 29 | better yet, accept a pull request.) 30 | 31 | ### Create and configure GCP project 32 | 1. Create Project in Cloud Console 33 | 1. Navigate to Compute Engine (to activate Compute Engine service) 34 | 1. Navigate to the API Library and activate Container Builder API 35 | 36 | 37 | ### Create Configs 38 | 1. Make a copy of `/Samples.properties`, renamed to `/Makefile.properties` 39 | 1. Alter value for `PROJECT` to your project id 40 | 1. Alter `ZONE` and `REGION` if you want to run this demo in a particular area. 41 | 1. Alter `CLUSTER` if you want to call your cluster something other than 42 | `whack-a-pod`. 43 | 1. Set `INGRESSNAME` if you need to use something other than the default. 44 | 1. Set `DOCKERREPO` if you need to use something other Google Container Registry. 45 | 1. Open a terminal in `/`. 46 | 1. Run `make config` to create your ingress file. 47 | 1. This should create the following file: 48 | 1. /apps/ingress/ingress.yaml 49 | 50 | 51 | >I use this application to show off Google Cloud Platform, so I tend set it up 52 | multiple times, once per region or datacenter. Therefore, I rename the `INGRESSNAME` and 53 | `CLUSTER` a bunch. If you only have one cluster, you don't have to fiddle with 54 | these. 55 | 56 | ### Build Infrastructure 57 | 1. Open a terminal in `/infrastructure/`. 58 | 1. Run `make build`. 59 | `make build` will do the following: 60 | 1. Create Kubernetes Cluster 61 | 1. Create 1 static ip addresse for use in the app 62 | 63 | >If you get the error `ResponseError: code=503, 64 | message=Project projectname is not fully initialized with the default service 65 | accounts. Please try again later.` You need to navigfate to Compute Engine in 66 | Google Cloud console to activate Compute Engine service. 67 | 68 | 69 | 70 | ### Build Application 71 | 1. Open a terminal in root of whack_a_pod location. 72 | 1. Run `make build` 73 | 1. Run `make deploy` 74 | 1. When process finishes Browse to the the IP address value for the ingress. 75 | 1. To get that address: `gcloud compute addresses describe #INGRESSNAME# --global` 76 | 77 | ## Run demo 78 | There are two skins to the game. 79 | 1. Carnival version: 80 | * http://[gamehost]/ 81 | 1. Google Cloud Next branded version: 82 | * http://[gamehost]/next.html 83 | * http://[gamehost]/advanced.html 84 | 85 | The advanced version of the game is a great demo for teaching some of the 86 | fundamentals of Kubernetes. It allows you to cordon and uncordon nodes of the 87 | Kubernetes cluster to simulate Node failure. In addition it shows which Pod of 88 | the Replica Set is actually answering calls for the service. 89 | 90 | ### Clean Up 91 | 1. Open a terminal in `/`. 92 | 1. Run `make clean` 93 | 1. Open a terminal in `/infrastructure/`. 94 | 1. Run `make clean` 95 | 96 | ## Minikube 97 | Whack a Pod can run on Minikube. Its performance isn't stellar, but the game 98 | versions of it run just as well a it does on a flaky conference wifi. 99 | 100 | ### Prerequisite 101 | * Install minikube 102 | [Directions](https://github.com/kubernetes/minikube/releases) 103 | * Enable ingress 104 | `minikube addons enable ingress` 105 | * Install xhyve driver (Mac OS]) 106 | [Directions](https://github.com/kubernetes/minikube/blob/master/docs/drivers.md) 107 | 108 | ### Docker Repository 109 | You can use the Container Registry based commands in the Makefiles to build and 110 | host your Docker images. 111 | 112 | 1. Open a terminal in root of whack_a_pod location. 113 | 1. Run `make build` 114 | 1. Make images publicly available by following [these directions](https://cloud.google.com/container-registry/docs/access-control) 115 | 116 | This still requires a Google Cloud Platform Project. If you would like to build 117 | them some other way, you can, nothing restricts you from doing so. Just make 118 | sure you set `$(DOCKERREPO)` to the right value in Makefile.properties. 119 | 120 | #### Docker Repository with DockerHub 121 | Alternatively, to host your images on DockerHub, 122 | 123 | 1. Create an account on DockerHub 124 | 2. Create an image repository on DockerHub 125 | 3. In the `Makefile.properties`, change the value of `PROJECT` so that it equals your image repository slug 126 | 4. In the `Makefile.properties`, change the value of `DOCKERREPO` so that it looks like `yourusername/$(PROJECT)` 127 | 5. Run `make build.dockerhub` 128 | 129 | Your repository should have three new images with the tags: 130 | - admin 131 | - api 132 | - game 133 | 134 | For example, if your username is `username` and your repository name is `wap`, your images will be pushed to: 135 | - username/wap:admin 136 | - username/wap:api 137 | - username/wap:game 138 | 139 | ### Running on Minikube 140 | 141 | 1. Open a terminal in root of whack_a_pod location. 142 | 1. Run `minikube start --vm-driver=xhyve` 143 | 1. Run `make deploy.minikube` 144 | 1. Run `minikube ip` to get the IP address of the Minikube deployment. 145 | 1. Create an entry in /etc/hosts pointing IP address to `minikube.wap`. 146 | 147 | ### Running on Minikube with DockerHub 148 | 1. Open a terminal in root of whack_a_pod location. 149 | 1. Run `minikube start` 150 | 1. Run `make deploy.minikube.dockerhub` 151 | 1. The last line of the previous command should contain an IP address beside a `"minikube.wap"` string 152 | 1. Run `sudo vim /etc/hosts`, append the last line to the `/etc/hosts` and save the file. 153 | 1. Wait for the ingress to obtain an IP address (run `kubectl get ing --watch` and wait till the `ADDRESS` column has a value) 154 | 1. Visit [http://minikube.wap](http://minikube.wap) in the browser 155 | 156 | ### Clean Minikube 157 | 1. Run `make clean.minikube` 158 | 1. Run `minikube stop` 159 | 160 | ### Running on any Kubernetes (generic) 161 | 162 | This method is for generic usage and can be run on any Kubernetes installation. There are few differences: 163 | * It will push built images to repo `DOCKERREPO` defined in Makefile.properties 164 | * It's agnostic of any loadbalancer in front of ingress so you can use `NodePort` type for ingress service 165 | * It works with RBAC model - proper serviceaccount and role bindings are created 166 | * It will deploy all objects in current namespace 167 | 168 | 1. Open a terminal in root of whack_a_pod location. 169 | 1. Build application with `make build.generic` **OR** skip building by setting `DOCKERREPO` to **cloudowski** and use prebuilt images availabe on dockerhub 170 | 1. Run `make deploy.generic` 171 | 1. Define name `whackapod.example.com` in your `/etc/hosts` pointing to IP address of your load balancer in front of ingress controller or one of nodes IP (when using `NodePort`) 172 | 1. Open your browser at [http://whackapod.example.com/](http://whackapod.example.com) 173 | 174 | ### Clean generic deployment 175 | 1. Run `make clean.generic` 176 | 177 | ## Architecture 178 | There are three Kubernetes services that make up the whole application: 179 | 1. Game 180 | Game contains all of the front end clients for the game, both the carnival 181 | version and the Google Cloud Next version. 182 | 1. Admin 183 | Admin contains all of the logic for managing the whole application. This is 184 | the application the front end calls to get a list of the pods running the 185 | color api, it also has calls to create and delete deployments, delete pods, and 186 | drain and uncordon nodes. 187 | 1. Api 188 | Api contains two service calls: color and color-complete. Color is a random 189 | hexidecimal RGB color value. Color-complete is the same as color, but also 190 | sends the pod name of the pod that answered the service call. 191 | 192 | 193 | "This is not an official Google Project." 194 | -------------------------------------------------------------------------------- /Sample.properties: -------------------------------------------------------------------------------- 1 | # Copyright 2017 Google Inc.
