Task 7: Verify the OCI Certificate with Load Balancer

Step 1: Obtain the Public IP of the Load Balancer

Log in to the OCI Console.

Navigate toNetworking>Load Balancers.

Click on PBT-CERT-LB-01.

Note thePublic IP Addressfrom the load balancer details page.

Step 2: Verify HTTPS Connection Using Cloud Shell

Open the OCI Cloud Shell from the top-right corner of the OCI Console.

Run the following command, replacing with the public IP you noted:

curl -k https://

Expected output: You should see the text "You are visiting Web Server 1" if the connection is successful. The -k flag ignores certificate validation errors (common during initial testing with self-signed or newly issued certificates).

If you encounter an error, ensure the load balancer is active, the listener is configured correctly, and the backend server (PBT-CERT-VM-01) is reachable.

Step 3: Verify in a Web Browser

Open a web browser.

Enter the following URL, replacing with the public IP you noted:

https://

If prompted with a certificate warning (e.g., due to a self-signed certificate or untrusted CA), accept the risk and proceed (click "Advanced" and "Proceed" or similar, depending on your browser).

Verify that the web page displays the text "You are visiting Web Server 1" from the index.html file created on PBT-CERT-VM-01.

Step 4: Troubleshoot (if needed)

If the text is not displayed:

Check the load balancer health status underBackend Sets>Healthin the OCI Console.

Ensure the security list PBT-CERT-LB-SL-01 allows port 443 and the compute instance security list allows port 80.

Verify the Apache service is running on PBT-CERT-VM-01 by SSHing in and running sudo systemctl status httpd.

To create a public subnet named IAD-SP-PBT-PUBSNET-01 within the VCN IAD-SP-PBT-VCN-01 using a CIDR block of 10.0.1.0/24 and configure it to use the Internet Gateway, follow these steps based on the Oracle Cloud Infrastructure (OCI) Networking documentation.

Step-by-Step Solution for Task 4: Create a Public Subnet

Log in to the OCI Console:

Use your OCI credentials to log in to the OCI Console (https://console.us-ashburn-1.oraclecloud.com ).

Ensure you have access to the assigned compartment.

Navigate to Virtual Cloud Networks:

From the OCI Console, click the navigation menu (hamburger icon) on the top left.

UnderNetworking, selectVirtual Cloud Networks.

Select the VCN:

Locate and click on the VCN named IAD-SP-PBT-VCN-01 created in Task 3.

UnderResources, selectSubnets.

Create a New Subnet:

Click theCreate Subnetbutton.

Configure the Subnet Details:

Name:Enter IAD-SP-PBT-PUBSNET-01.

Compartment:Ensure it is set to the assigned compartment.

Subnet Type:SelectPublic Subnet.

CIDR Block:Enter 10.0.1.0/24.

Route Table:Select the default route table associated with the VCN (ensure it includes a route to the Internet Gateway with destination 0.0.0.0/0).

Subnet Access:SelectPublic Subnetand ensure the Internet Gateway is associated.

DHCP Options:Leave as default or customize if required.

Security List:Use the default security list or create a new one with appropriate ingress/egress rules (e.g., allow TCP port 22 for SSH and all egress traffic).

Associate the Internet Gateway:

Verify that the subnet is configured to route traffic through the Internet Gateway. This is automatically handled if you selected the public subnet option and the VCN’s route table is correctly set (as configured in Task 3).

If needed, edit the route table for the subnet to ensure a rule exists:

Destination CIDR Block:0.0.0.0/0

Target Type:Internet Gateway

Target:Select the Internet Gateway associated with IAD-SP-PBT-VCN-01.

Create the Subnet:

ClickCreateto provision the subnet.

Once created, the subnet will be listed under the VCN’s subnets.

Verify the Configuration:

Go to the subnet details page for IAD-SP-PBT-PUBSNET-01.

Confirm the CIDR block is 10.0.1.0/24 and that it is a public subnet with Internet Gateway access.

Notes

Ensure the CIDR block 10.0.1.0/24 does not overlap with existing subnets in the VCN (10.0.0.0/16, including 10.0.10.0/24 from Task 3).

The Internet Gateway association relies on the route table configuration from Task 3. If it’s missing, update the route table as described in Step 6.

Task 3: Create a Master Encryption Key

Step 1: Access the OCI Vault

Log in to the OCI Console.

Navigate toIdentity & Security>Vault.

Select the root compartment.

Locate and click on the vault named PBI_Vault_SP.

Step 2: Create the Master Encryption Key

In the PBI_Vault_SP vault details page, underResources, clickKeys.

ClickCreate Key.

Enter the following details:

Name: Replace with your username (e.g., if your username is 99008677-lab.user01, remove special characters like - and . to get 99008677labuser01, then use PBT-CERT-MEK-0199008677labuser01).

Key Shape: SelectRSAwith4096 bits.

Protection Mode: SelectHSM(Hardware Security Module) if available, orSoftwareif HSM is not required (based on vault capabilities).

Compartment: Ensure it’s set to the root compartment (where PBI_Vault_SP resides).

Leave other settings (e.g., key usage) as default unless specified.

ClickCreate Keyand wait for the key to be generated.

Step 3: Retrieve and Enter the OCID

After the key is created, go to theKeyssection under PBI_Vault_SP.

Click on the key named PBT-CERT-MEK-01 (e.g., PBT-CERT-MEK-0199008677labuser01).

Copy theOCID(a long string starting with ocid1.key., unique to your tenancy) from the key details page.

Enter the copied OCID exactly as it appears into the provided text box.

Task 4: Create a Certificate Authority (CA)

Create a certificate authority, where:

CA name: PBT-CERT-CA-01-

For example, if your username is 99008677-lab.user01, then the certificate authority name should be PBT-CERT-CA-01990086771abuser01

Ensure you eliminate special characters from the user name.

Common name: PBT-CERT-OCICA-01

Master Encryption Key: PBT-CERT-MEK-01 (created in the previous task)

Answer: See the solution below in Explanation.

Task 4: Create a Certificate Authority (CA)

Step 1: Access the OCI Vault

Log in to the OCI Console.

Navigate toIdentity & Security>Vault.

Select the root compartment.

Locate and click on the vault named PBI_Vault_SP.

Step 2: Create the Certificate Authority

In the PBI_Vault_SP vault details page, underResources, clickCertificate Authorities.

ClickCreate Certificate Authority.

Enter the following details:

Name: Replace with your username (e.g., if your username is 99008677-lab.user01, remove special characters like - and . to get 99008677labuser01, then use PBT-CERT-CA-0199008677labuser01).

Common Name: Enter PBT-CERT-OCICA-01.

Master Encryption Key: Select the PBT-CERT-MEK-01 key created in Task 3 (e.g., PBT-CERT-MEK-0199008677labuser01).

Subject: Leave as default or adjust (e.g., Organization, Country) if required by your setup.

Validity Period: Set as needed (e.g., 10 years), or use the default.

Compartment: Ensure it’s set to the root compartment.

ClickCreate Certificate Authorityand wait for the CA to be provisioned.

Step 3: Verify the Certificate Authority

After creation, go to theCertificate Authoritiessection under PBI_Vault_SP.

Confirm the CA PBT-CERT-CA-01 (e.g., PBT-CERT-CA-0199008677labuser01) is listed and its status is active.
