Clone the Module

Now, you'll want a local copy of this repo. You can make that with the commands:

git clone https://github.com/oracle-quickstart/oci-arch-tomcat-autonomous.git
cd oci-arch-tomcat-autonomous
ls

Prerequisites

First off, you'll need to do some pre-deploy setup. That's all detailed here.

Setup TF_VAR_... to setup your environment

export TF_VAR_user_ocid=ocid1.user.oc1...
export TF_VAR_fingerprint=xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
export TF_VAR_private_key_path=/path/to/private.key.pem
export TF_VAR_tenancy_ocid=ocid1.tenancy.oc1...

Secondly, create a terraform.tfvars file and populate with the following information:

# Authentication
tenancy_ocid         = "<tenancy_ocid>"

# SSH Keys
ssh_public_key  = "<public_ssh_key_path>"

# Region
region = "<oci_region>"

# Compartment
compartment_ocid = "<compartment_ocid>"

Deploy:

terraform init
terraform plan
terraform apply

Testing your deploymnet

After the deployment is finished, you can test that your tomcat was deployed correctly and can access the database going to the urls:

http://<load balancer IP>/JDBCSample/JDBCSample_Servlet

http://<load balancer IP>/JDBCSample/UCPServlet

Destroy the Deployment

When you no longer need the deployment, you can run this command to destroy it:

terraform destroy

Tomcat-Autonomous Database Architecture

Although the diagram shows a private subnet for the Tomcat servers, the scripts are provisioning them on a public subnet as there is no bastion to allow access to the servers.
