This section describes preparing Oracle Database Cloud Service and deploying TechCo Demo application to an Oracle Java Cloud Service instance by using the WLST script.
This tutorial is a shortcut to quickly deploy TechCo sample application using a single script which
- creates user and tables on Oracle Database Cloud Service
- creates resources on Oracle Java Cloud Service
- deploys demo application to OracleJava Cloud Service.
- This lab requires to build the model of on-premise environment. See Preparation of the on-premise environment
- Running Database Cloud Service instance to prepare for TechCo Demo application.
- Running Java Cloud Service instance to deploy TechCo Demo application.
To avoid providing SSH private key's passphrase multiple time during script execution you need to register your private key and passphrase in SSH-Agent running on your desktop (VirtualBox image). Open a terminal and change to GIT_REPO_LOCAL_CLONE/cloud-utils folder. Then add your private key's passphrase to SSH-Agent. Your default private key file's name is pk.openssh. If not define the proper private key's file name:
$ [oracle@localhost Desktop]$ cd /GIT_REPO_LOCAL_CLONE/cloud-utils
$ [oracle@localhost cloud-utils]$ ssh-add pk.openssh
The SSH-Agent will ask the passphrase if the private key has. In case you generated public and private key using cloud-utils then you can check for passphrase the ssh.passphrase property's value in the environment.properties file. Type the passphrase:
Enter passphrase for pk.openssh:
Identity added: pk.openssh (pk.openssh)
[oracle@localhost cloud.demos]$
Now the identity has been added so no need to provide the passphrase in the future during ssh or scp execution.
The Database Cloud Service, Java Cloud Service preparation and application deployment can be completed executing a single script. Change the directory to GIT_REPO_LOCAL_CLONE/techco-app folder and invoke 'deployTechCo.sh' script:
$ [oracle@localhost Desktop]$ cd /u01/content/cloud-native-devops-workshop/techco-app
$ [oracle@localhost techco-app]$ ./deployTechCo.sh
../cloud-utils/environment.properties found.

TechCo application has been deployed.

You should see at the end the successful deployment message.
To test an application that you have deployed and started on an Oracle Java Cloud Service instance that does not include a load balancer requires public IP address of the compute node.
The public IP address of the allocated Oracle Java Cloud Service was provided by the instructor.
Optionally you may query Oracle Cloud through REST API about the JCS public IP using the maven based tool available on your desktop (VirtualBox image). Open a terminal and change to the GIT_REPO_LOCAL_CLONE/cloud-utils/ folder. Then execute the following command:
$ [oracle@localhost Desktop]$ cd /u01/content/cloud-native-devops-workshop/cloud-utils
$ [oracle@localhost cloud-utils]$ mvn -Dgoal=jcs-get-ip

Please open a browser and write the following URL using your Oracle Java Cloud Service (JCS) IP address: https://<jcs-public-ip-address>/TechCo-ECommerce
You should now see the home page of the sample application.
If your Java Cloud Service has Load Balancer configured then use its public IP address to access the TechCo Demo application.
