Deploying an Application with the JBoss EAP Deployment Scanner

JBoss Enterprise Application Platform provides an extensive Java EE-based application server to which we can deploy and manage our applications. Oftentimes, this can be as simple as deploying a provided WAR or EAR file to our configured server. In this lab, we'll specifically explore how to use the standalone deployment scanner to deploy our applications automatically.

Configure the Deployment Scanner
1. Move into the JBoss EAP home directory:
```
cd /opt/jboss-eap
```
2. Access the JBoss Management CLI:
```
sudo ./bin/jboss-cli.sh
```
3. Connect:
```
connect
```
4. Move to the deployment scanner node:
```
cd /subsystem=deployment-scanner/scanner=default
```
5. Disable auto-deployment scanner:
```
:write-attribute(name=auto-deploy-zipped,value=false)
```
6. Exit the CLI:
```
exit
```
Challenge

Add the Application to the Scanned Directory
1. Look for the .war file in the cloud_user's home directory:
```
ls ~
```
2. Copy the kitchensink.war file to /opt/jboss-eap/standalone/deployments:
```
sudo cp ~/kitchensink.war standalone/deployments/kitchensink.war
```
3. Since we disabled auto-deployment, we need to create a marker file to trigger deployment:
```
sudo touch standalone/deployments/kitchensink.war.dodeploy
```
4. Immediately look in standalone/deployments -- notice the kitchensink.war.isdeploying file:
```
ls standalone/deployments/
```
5. When the file changes to kitchensink.war.deployed, we'll know our application is ready. We can check this by either looking at our application at PUBLICIP:8080/kitchensink or by looking at our list of deployments in either the console or the CLI.
Challenge

Disable the Application
To disable the application, remove the kitchensink.war.deployed file. You can always redeploy the application by adding a .dodeploy marker again:
```
sudo rm standalone/deployments/kitchensink.war.deployed
```
