The repository will be kept available in read-only mode. 4 | > 5 | # Build a secure microservices-based banking application 6 | 7 | ### Use API Connect for OAuth functions, App Connect for API orchestration, and Node.js to develop the banking application 8 | 9 | In a microservices based solution, security and orchestration of workflows are common requirements across solutions. 10 | 11 | Let us consider the example of funds transfer in a personal banking scenario. The customer wishing to perform a funds transfer must be securely authenticated and authorized to perform the operation. Also, the funds transfer functionality requires integration with other applications or APIs to complete a transaction. 12 | 13 | In this code pattern, we demonstrate the security and orchestration of microservices using a personal banking use-case scenario. The IBM API Connect and IBM App Connect available on IBM Cloud is used to implement the functionality. API Connect is used to provide OAuth based authorization security to microservices, and App Connect Enterprise for easier and seamless integration of APIs (with zero code) for a business user. The solution comprises authentication and funds transfer functionality. 14 | 15 | At the end of this code pattern, users will understand: 16 | * Authentication and authorization using OAuth in API Connect. 17 | * Funds transfer operation with orchestration of APIs exposed by `Account Management Service`, `Credit Account Service` and `Debit Account Service` using App Connect. 18 | * To build and deploy Node.js microservices on IBM Kubernetes Service. 19 | * Development of a client application using Node-RED. 20 | 21 | The `Public Access Code` scheme of OAuth2 is used for authorization. Since the customer has to authorize the operation, the public scheme is suitable as the application is incapable of maintaining the secrecy of the client secret. In the access code flow, the application has the user provide authorization through a form provided by the gateway server, which, if they grant authorization, provides an authorization code to the application. 22 | 23 | In the funds transfer scenario, the following operations are orchestrated using `App Connect` flow: 24 | - Balance check using `Account Management Service`. 25 | - Perform a debit of customer account using `Debit Account Service`. 26 | - Perform a credit of payee account using `Credit Account Service`. 27 | 28 | In case of a failure in the credit operation, the transaction is rolled back and the amount is credited back to the customer account. 29 | 30 | # Flow 31 | 32 | ![Flow Diagram](images/architecture.png) 33 | 34 | 1. User logs-in to the client application. 35 | 2. Login Request will go to API Connect. 36 | 3. API Connect uses Login API for authentication. And then it generates OAuth token for authorization. 37 | 4. The user invokes the `funds transfer` transaction using the OAuth token. The request goes to app connect flow which internally uses `Account Management API`, `Credit Account API` and `Debit Account API`. 38 | 39 | > Note: 40 | > * All microservices are deployed on IBM Kubernetes Service. 41 | > * All APIs interact with MongoDB. 42 | 43 | # Pre-requisites 44 | * [IBM Cloud Account](https://cloud.ibm.com) 45 | * [Git Client](https://git-scm.com/downloads) - needed for clone commands. 46 | 47 | # Steps 48 | 49 | Follow these steps to setup and run this code pattern. The steps are described in detail below. 50 | 51 | 1. [Get the code](#1-get-the-code) 52 | 2. [Create IBM Cloud Services](#2-create-ibm-cloud-services) 53 | 3. [Setup environment for Kubernetes CLI](#3-setup-environment-for-kubernetes-cli) 54 | 4. [Deploy Mongo DB](#4-deploy-mongo-db) 55 | 5. [Deploy Microservices](#5-deploy-microservices) 56 | 6. [Configure App Connect](#6-configure-app-connect) 57 | 7. [Configure API Connect](#7-configure-api-connect) 58 | 8. [Deploy client application](#8-deploy-client-application) 59 | 9. [Analyze the result](#9-analyze-the-result) 60 | 61 | ## 1. Get the code 62 | 63 | - Clone the repo using the below command. 64 | ``` 65 | git clone https://github.com/IBM/microservices-using-apiconnect-and-appconnect.git 66 | ``` 67 | 68 | ## 2. Create IBM Cloud Services 69 | 70 | ### Create IBM Kubernetes Service 71 | 72 | Create a Kubernetes cluster with [Kubernetes Service](https://cloud.ibm.com/containers-kubernetes/catalog/cluster) using IBM Cloud Dashboard. This pattern uses the _free cluster_. 73 | 74 | ![](images/create_service.png) 75 | 76 | > Note: It can take up to 15-20 minutes for the cluster to be set up and provisioned. 77 | 78 | ### Create App Connect service instance 79 | 80 | Create an instance of [IBM App Connect](https://cloud.ibm.com/catalog/services/app-connect). Ensure `lite` plan is selected. Click `Create`. 81 | 82 | ![Create App Connect Instance](./images/app-connect-instance-create.png) 83 | 84 | A new instance of IBM App Connect should be created. 85 | 86 | ### Create API Connect service instance 87 | 88 | Create an instance of [IBM API Connect](https://cloud.ibm.com/catalog/services/api-connect). Ensure `lite` plan is selected. Click `Create`. 89 | 90 | ![Create API Connect Instance](./images/api-connect-instance-create.png) 91 | 92 | A new instance of IBM API Connect should be created. 93 | 94 | ### Create Node-RED service instance 95 | 96 | Create an instance of [Node-RED](https://cloud.ibm.com/catalog/starters/node-red-starter). Ensure `lite` plan is selected. Click `Create`. 97 | 98 | ![Create Node-RED Instance](./images/node-red-instance-create.png) 99 | 100 | A new instance of Node-RED should be created. 101 | 102 | **Note the base url of Node-RED** as shown below: 103 | 104 | ![Note Node-RED base url](./images/note_node_red_url.png) 105 | 106 | ## 3. Setup environment for Kubernetes CLI 107 | 108 | **Check status of your Kubernetes Cluster** 109 | 110 | * Check the status of your cluster `IBM Cloud Dashboard -> Clusters -> `. If status is not `Normal`, then you need to wait for some more time to proceed further. 111 | 112 | * Once your cluster is ready, open the access tab `IBM Cloud Dashboard -> Clusters -> -> Access`. Perform the steps provided under this section to get access of your cluster through `kubectl` CLI. 113 | 114 | * Verify that the kubectl commands run properly with your cluster by checking the Kubernetes CLI server version. 115 | 116 | ``` 117 | $ kubectl version --short 118 | Client Version: v1.14.6 119 | Server Version: v1.16.7+IKS 120 | ``` 121 | 122 | **Get the public IP for Kubernetes Cluster** 123 | 124 | Once cluster is up and running then find out the public IP of your cluster. It will be required for further steps. 125 | 126 | * Go to `IBM Cloud Dashboard -> Clusters -> `. It gives you details of the cluster. 127 | 128 | * Access `Worker Nodes` tab, it will show you the public IP of your cluster as shown in below screenshot. 129 | 130 | ![](images/worker-nodes.png) 131 | 132 | Make a note of this public IP. It will be used in further steps. 133 | 134 | **Create namespace on IBM Cloud container registry** 135 | 136 | IBM Cloud Container Registry is used to store and access private container images. If you have not created namespace before or you want to use a different 137 | namespace than existing one, then need to create a new namespace. You can create a namespace through interface as 138 | `Navigation > Kubernetes > Registry > Namespaces > Create` or using the following CLI commands: 139 | 140 | ``` 141 | # To create a namespace 142 | $ ibmcloud cr namespace-add 143 | 144 | # To verify that namespace is created 145 | $ ibmcloud cr namespace-list 146 | ``` 147 | 148 | ## 4. Deploy Mongo DB 149 | 150 | In this pattern, mongo db will be deployed in a container and will be used by all the microservices. Perform the following steps to deploy Mongo DB in a container. 151 | 152 | ``` 153 | $ cd mongodb 154 | $ kubectl create -f deploy_mongodb.yaml 155 | ``` 156 | 157 | After deployment, the status can be checked as: 158 | ``` 159 | $ kubectl get pods 160 | NAME READY STATUS RESTARTS AGE 161 | mongo-8dc7685d7-nxrcr 1/1 Running 0 73s 162 | 163 | $ kubectl get services |grep mongo 164 | mongo NodePort 172.21.84.39 27017:32643/TCP 11m 165 | ``` 166 | 167 | The **connection_url** to connect to mongodb will use `:`. Use the public IP of your Kubernetes cluster retrieved in step 3 above. The mongo_service_port in this case, is 32643 (as shown in the above command). This connection url will be used by microservices to connect with mongo db. 168 | 169 | ## 5. Deploy Microservices 170 | 171 | For this application, we are creating microservices for authentication (login), bank account management, credit account and debit account functionality. A set of user credentials and bank account details are pre-defined in Mongo DB. 172 | 173 | Perform the following steps to deploy microservices. 174 | 175 | **Update MongoDB Connection String** 176 | 177 | Prepare connection url as explained in step 4. Then execute the following commands to update mongo db connection url in app.js of all four microservices as per your system(linux/mac). 178 | 179 | ``` 180 | ## For MAC 181 | cd ../microservices 182 | sed -i '' s#CONNECTION_URL#x.x.x.x:port# login_service/app.js 183 | sed -i '' s#CONNECTION_URL#x.x.x.x:port# account_management_service/app.js 184 | sed -i '' s#CONNECTION_URL#x.x.x.x:port# debit_service/app.js 185 | sed -i '' s#CONNECTION_URL#x.x.x.x:port# credit_service/app.js 186 | 187 | ## For Linux 188 | cd ../microservices 189 | sed -i s#CONNECTION_URL#x.x.x.x:port# login_service/app.js 190 | sed -i s#CONNECTION_URL#x.x.x.x:port# account_management_service/app.js 191 | sed -i s#CONNECTION_URL#x.x.x.x:port# debit_service/app.js 192 | sed -i s#CONNECTION_URL#x.x.x.x:port# credit_service/app.js 193 | ``` 194 | 195 | **Prepare deploy target** 196 | 197 | All four docker images needs to be pushed to your docker image registry on IBM Cloud. You need to set the correct deploy target. Depending on the region you have created your cluster in, your URL will be in the following format: 198 | 199 | ``` 200 | .icr.io//: 201 | ``` 202 | 203 | The following command tells you the Registry API endpoint for your cluster. You can get region abbreviation from the output. 204 | 205 | ``` 206 | ibmcloud cr api 207 | ``` 208 | 209 | To get namespace use the following command: 210 | ``` 211 | ibmcloud cr namespaces 212 | ``` 213 | 214 | For example, to deploy the login microservice to my docker image registry in the US-South region, my deploy_target will be: 215 | ``` 216 | us.icr.io/test_namespace/login_app:v1.0 217 | ``` 218 | 219 | **Deploy login microservice** 220 | 221 | Execute the following steps. 222 | 223 | ``` 224 | $ cd login_service 225 | ``` 226 | Build dockerfile and push the image to registry. 227 | 228 | ``` 229 | $ ibmcloud cr build -t . 230 | ``` 231 | 232 | Update image location(deploy target) in `deploy.yaml`. 233 | 234 | ``` 235 | $ sed -i '' s#IMAGE## deploy.yaml ## mac 236 | OR 237 | $ sed -i s#IMAGE## deploy.yaml ## linux 238 | 239 | $ kubectl create -f deploy.yaml 240 | 241 | $ kubectl get services|grep login 242 | login-service NodePort 172.21.113.169 8080:32423/TCP 31s 243 | ``` 244 | 245 | The login microservice will be accessible at `http://:`. Use the public IP of your Kubernetes cluster retrieved in step 5. The login_service_nodeport in this case is 32423 (shown in above command). To use login functionality of this service, access `http://:32423/login`. 246 | 247 | 248 | **Deploy account_management service** 249 | 250 | Following are the steps for account_management service. 251 | 252 | ``` 253 | cd ../account_management_service 254 | $ ibmcloud cr build -t . 255 | 256 | $ sed -i '' s#IMAGE## deploy.yaml ## mac 257 | OR 258 | $ sed -i s#IMAGE## deploy.yaml ## linux 259 | 260 | $ kubectl create -f deploy.yaml 261 | 262 | $ kubectl get services | grep acc 263 | account-details-service NodePort 172.21.166.106 8080:32424/TCP 33s 264 | ``` 265 | Account management functionality of this service can be accessed by using `http://:32424/check_accounts`. 266 | 267 | **Deploy debit_account service** 268 | 269 | Following are the steps for debit account service. 270 | 271 | ``` 272 | cd ../debit_service 273 | $ ibmcloud cr build -t . 274 | 275 | $ sed -i '' s#IMAGE## deploy.yaml ## mac 276 | OR 277 | $ sed -i s#IMAGE## deploy.yaml ## linux 278 | 279 | $ kubectl create -f deploy.yaml 280 | 281 | $ kubectl get services |grep debit 282 | debit-account-service NodePort 172.21.138.208 8080:32425/TCP 16s 283 | ``` 284 | 285 | Debit account functionality of this service can be accessed by using `http://:32425/debit_account`. 286 | 287 | **Deploy credit_account service** 288 | 289 | Following are the steps for credit account service. 290 | 291 | ``` 292 | cd ../credit_service 293 | $ ibmcloud cr build -t . 294 | 295 | $ sed -i '' s#IMAGE## deploy.yaml ## mac 296 | OR 297 | $ sed -i s#IMAGE## deploy.yaml ## linux 298 | 299 | $ kubectl create -f deploy.yaml 300 | 301 | $ kubectl get services|grep credit 302 | credit-account-service NodePort 172.21.51.254 8080:32426/TCP 11s 303 | ``` 304 | 305 | Credit account functionality of this service can be accessed by using `http://:32426/credit_account` 306 | 307 | > Note: We have defined NodePort of all four microservices. Please change the ports if not available in your Kubernetes Cluster. 308 | 309 | If you want to test your microservices, please refer to [test instructions](https://github.com/IBM/microservices-using-apiconnect-and-appconnect/blob/master/TestServices.md). Else continue to next step. 310 | 311 | ## 6. Configure App Connect 312 | 313 | Use App Connect to connect your different applications and make your business more efficient. Set up flows that define how data is moved from one application to one or more other applications. App Connect supports a range of skill levels and interfaces, giving you the flexibility to create integrations without writing a single line of code.

You can import OpenAPI documents that contain API definitions into IBM App Connect. Each imported document is added as an API to the App Connect catalog of applications and APIs, and can be used to call the API from a flow. 324 | 325 | For the microservices used in this code pattern, the REST APIs definition files are available under `app-connect-resources/microservices-apis` folder. 326 | 327 | ![Add API to Catalog](./images/add-api-to-catalog.gif) 328 | - On App Connect top menu, click `Catalog` -> `APIs` -> `Add your API or web service now` -> `Add an OpenAPI definition, WSDL or ZIP` 329 | - Browse to `app-connect-resources/microservices-apis` folder and select `Account_Check.json` file. 330 | - Specify the name to be `Account_Check`. While any unique name can be given to APIs, we will maintain the names specified here so that the flow that we will import in later steps work with the APIs, without error. 331 | - Optional. Add a description that summarizes the function of the API. 332 | - Click `Add`. Click `Add your API or web service now`. Click "Add an OpenAPI definition, WSDL or Zip". 333 | - Select the `Account Check` API json file to import. 334 | - Enter name as `Account_Check`. Enter something in Description field, if required. Then click on `Add API`. 335 | - Expoand `Imported` and click `Connect`. 336 | - Under `Override the hostnameand port of the Account_Check server:(optional)` enter the Account_Check microservice's IP address and port. e.g. `http://173.193.79.231:32424`. 337 | - Click `Connect`. 338 | - Similarly add APIs `Debit_Transaction` (name should be `Debit_Transaction`) and `Credit_Transaction` (name should be `Credit_Transaction`). 339 | - As a sanity check, verify that the microservices are working fine using a REST client like postman. 340 | 341 | #### Import flow 342 | - Click `Import Flow` button. The flow should be imported now. 343 | - On the top right corner of the browser page, click the `New` button and select `Import Flow...`. 344 | ![Import Flow](./images/import-flow.gif) 345 | - Click "Add a YAML file".
