Apache Tomcat® is an open source Java application server. It implements the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.
managethe following types of resources in your Oracle Cloud Infrastructure tenancy:
Quota to create the following resources: 1 VCN, 3 subnets, 1 Internet Gateway, 1 NAT Gateway, 2 route rules, 1 ATP instance, and 3 compute instances (bastion host + 2 Tomcat servers).
Deploy Using Oracle Resource Manager
If you aren't already signed in, when prompted, enter the tenancy and user credentials.
Review and accept the terms and conditions.
Select the region where you want to deploy the stack.
Follow the on-screen prompts and instructions to create the stack.
After creating the stack, click Terraform Actions, and select Plan.
Wait for the job to be completed, and review the plan.
To make any changes, return to the Stack Details page, click Edit Stack, and make the required changes. Then, run the Plan action again.
If no further changes are necessary, return to the Stack Details page, click Terraform Actions, and select Apply.
Deploy Using the Terraform CLI
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-devrel/terraform-oci-arch-tomcat-autonomous.git cd terraform-oci-arch-tomcat-autonomous ls
First off, you'll need to do some pre-deploy setup. That's all detailed here.
terraform.tfvars file, and specify the following variables:
# Authentication tenancy_ocid = "<tenancy_ocid>" user_ocid = "<user_ocid>" fingerprint = "<finger_print>" private_key_path = "<pem_private_key_path>" # Region region = "<oci_region>" # Compartment compartment_ocid = "<compartment_ocid>" # ATP instance Password atp_password = "<atp_password>" # Number of Tomcat nodes (optional) numberOfNodes = 2 # Customer SSH Public Key (optional) ssh_public_key = "<ssh_public_key>"
Create the Resources
Run the following commands:
terraform init terraform plan terraform apply
Testing your Deployment
After the deployment is finished, you can test that your Tomcat was deployed correctly and can access the tomcat demo application with ATP. Pick up the value of the todoapp_url:
todoapp_url = http://126.96.36.199/todoapp/list
Then copy it into Web browser. Here is the example of the succesfull outcome:
As the load balancer alternates between the 2 Tomcat nodes, the session data should persist.
Destroy the Deployment
When you no longer need the deployment, you can run this command to destroy the resources:
