Workshop - Deploy an Artificial Intelligence Microservice

Deploy an Artificial Intelligence Microservice

Prerequisites
- The instructor should Setup Workshop Environment
- The student should Setup CLI and Terminal Shell
Instructor will provide the following info:
- OpenShift Console URL (OCP_CONSOLE_URL)
- The username and password for OpenShift and Git Server (default values are user01, user02, etc.. for users and password for password).
Set TOOLKIT_USERNAME environment variable. If you are participation in a workshop replace userdemo with your assigned username (ex. user01).
```
TOOLKIT_USERNAME=userdemo
```
Login to OpenShift using oc
- If using IBM Cloud cluster then login with your IBM account email and IAM API Key or Token by using the Copy Login Command
- If using a cluster that was configured with the workshop scripts outside IBM Cloud then use respective assigned username (ex. user01), and the password is password
```
oc login $OCP_URL -u $TOOLKIT_USERNAME -p password
```
Set TOOLKIT_PROJECT environment variable If you are participation in a workshop replace projectdemo based on your assigned username (ex. project01).
```
TOOLKIT_PROJECT=projectdemo
```

Create a project/namespace using your project as prefix, and -dev and suffix

oc sync $TOOLKIT_PROJECT-dev

Fork application template git repo
- Open Developer Dashboard from the OpenShift Console
- Select Starter Kits
- Select One in our case Artificial Intelligence Microservice
- Click Fork
- Login into GIT Sever using the provided username and password (ie userdemo and password)
- Click Fork Repository

Setup environment variable GIT_URL for the git url using the value from previous step or as following. Note: We are including username/password in git url for simplicity of this lab. You would NOT want to do this in your development environment.

GIT_REPO=ai-model-object-detector
GIT_URL=http://${TOOLKIT_USERNAME}:password@$(oc get route -n tools gogs --template='{{.spec.host}}')/${TOOLKIT_USERNAME}/${GIT_REPO}
echo GIT_URL=${GIT_URL}

Clone the git repository and change directory

cd $HOME
git clone $GIT_URL app
cd app

Create a Tekton pipeline for the application
```
oc pipeline --tekton
```
- Use down/up arrow and select ibm-general
- Enter n and hit Enter to disable image scanning
- Hit Enter to enable Dockerfile linting
- Hit Enter to select default health endpoint /
- Open the url to see the pipeline running in the OpenShift Console
Verify that Pipeline Run completed successfully
- On the OpenShift web console select Pipelines
- At the top of the page select your development project/namespace created above (ex. project01-dev)
- The app pipeline last run status should be Succeeded
Review the Pipeline Tasks/Stages.
- Click on the last run
- Click on the Test task and view the logs
- Open SonarQube from Console Link
- Open Registry from Console Link
- Open Artifactory from Console Link
The gitops step of the pipeline triggeres Argo CD to deploy the app to QA. Select Developer perspective, select project $TOOLKIT_PROJECT-qa and then select Topology from the Console and verify the application running
Open the application route url and try out the application using the swagger UI or append /app to the URL to load Web UI for the Application. You can download the this sample picture to test the app

Make a change to the application in the git repository and see the pipeline running again from the Console. Lets chagne the Machine Learning being used from ssd_mobilenet_v1 to faster_rcnn_resnet101

git config --local user.email "${TOOLKIT_USERNAME}@example.com"
git config --local user.name "${TOOLKIT_USERNAME}"
sed -i 's/ssd_mobilenet_v1/faster_rcnn_resnet101/' Dockerfile
git add .
git commit -m "update model"
git push -u origin master

Verify that change in Git Server and Git WebHook
- Open Git Dev from Console Link
- Navigate to user app git repository
- Review the recent commit
- Review the webhook recent delivery
Verify that a new Pipeline starts successfully
Verify that the App manifests are being updated in the gitops repo in the git account toolkit under the qa directory.
- Open Git Ops from Console Link
- Select toolkit/gitops git repository
Congratulations you finished this lab, continue with lab Promote an Application using CD with GitOps and ArgoCD
