Task 6: Create Load Balancer and Attach Certificate
Step 1: Create the Load Balancer
Log in to the OCI Console.
Navigate to Networking > Load Balancers.
Click Create Load Balancer.
Enter the following details:
Name: PBT-CERT-LB-01
Compartment: Select your assigned compartment.
Load Balancer Type: Select Public.
Virtual Cloud Network: Select PBT-CERT-VCN-01.
Subnet: Select LB-Subnet-PBT-CERT-SNET-02.
Shape: Choose a shape (e.g., 10 Mbps, adjust based on needs).
Click Next.
Leave backend sets and listeners as default for now (we'll configure the listener next).
Click Create Load Balancer and wait for it to be provisioned.
Step 2: Create a Listener
Once the load balancer is created, go to the Load Balancers page and click on PBT-CERT-LB-01.
Under Resources, click Listeners.
Click Create Listener.
Enter the following details:
Name: PBT-CERT-LB_LTSN_01
Protocol: Select HTTPS.
Port: Enter 443.
Certificate: Click Add Certificate, then select the PBT-CERT-01<username> certificate (e.g., PBT-CERT-0199008677labuser01) created in Task 5.
Leave other settings (e.g., SSL handling) as default unless specified.
Click Create.
Step 3: Configure the Backend Set
In the PBT-CERT-LB-01 details page, under Resources, click Backend Sets.
Click Create Backend Set (if not already created).
Enter basic details (e.g., name like PBT-CERT-BS-01).
Add a backend server:
IP Address: Use the private IP of PBT-CERT-VM-01 (find this in the instance details under Compute > Instances).
Port: 80 (HTTP, as configured on the web server).
Protocol: HTTP.
Click Create.
Step 4: Attach the Security List to the Subnet
Navigate to Networking > Virtual Cloud Networks.
Select PBT-CERT-VCN-01 and click Subnets.
Click on LB-Subnet-PBT-CERT-SNET-02.
Under Security Lists, ensure PBT-CERT-LB-SL-01 is attached. If not:
Click Edit.
Remove the default security list and add PBT-CERT-LB-SL-01.
Click Save Changes.
Step 5: Verify the Configuration
Ensure the load balancer health status is OK (check under Backend Sets > Health).
Test by accessing https://<load-balancer-public-ip> in a browser (replace with the public IP from the load balancer details).
