Challenge 3 - Task 3 of 4

Set Up a Bastion Host to Access the Compute Instance in a Private Subnet Scenario

A compute instance is provisioned in a private subnet that is not accessible through the Internet. To access the compute instance resource in a private subnet, you must provide a time-bound SSH session without deploying and maintaining a public subnet and a jump server, which eliminates the hassle and potential attack surface from remote access.

To complete this deployment, you have to perform the following tasks in the environment provisioned for you:

• Configure a Virtual Cloud Network (VCN) and a Private Subnet.

• Provision a Compute Instance in the private subnet and enable Bastion Plugin.

• Create a Bastion and Bastion session.

• Connect to a compute instance using Managed SSH session.

Note: You are provided with access to an OCI Tenancy, an assigned compartment, and OCI credentials. Throughout your exam, ensure to use the assigned Compartment 99233424-C01 and Region us-ashburn-1

Complete the following tasks in the provisioned OCI environment:

1.      Create a Bastion with the name SPPBTBASTION99233424-lab.user01

[Eliminate Specical Characters] Eg:SPPBTBASTION992831403labuser13

2.      Create a Session with the name PBT-1-Session-01, for compute instance in private subnet, with default username as "opc"

Complete the following tasks in the provisioned OCI environment:

Create a Compute Instance with the name PBT-BAS-VM-01, using the "Oracle Linux 8" image and shape "VM.Standard2.1", without SSH key and enable Bastion plugin.

Challenge 1 - Task 3 of 5

Authorize OCI Resources to Retrieve the Secret from the Vault

Scenario

You are working on a Python program running on a compute instance that needs to access an external service. To access the external service, the program needs credentials (password). Given that it is not a best security practice, you decide not to hard code the credential in the program. Instead, you store the password (secret) in a vault using the OCI Vault service. The requirement now is to authorize the compute instance so that the Python program can retrieve the password (secret) by making an API call to the OCI Vault.

Preconfigured

To complete this requirement, you are provided with:

• An OCI Vault to store the secret required by the program, which is created in the root compartment as PBT_Vault_SP.
• An instance principal IAM service, which enables instances to be authorized actors (principals) that can retrieve the secret from the OCI Vault.
• A dynamic group named PBT_Dynamic_Group_SP with permissions to access the OCI Vault. This dynamic group includes all of the instances in your compartment.
• Access to Cloud Shell.
• Permissions to perform only the tasks within the challenge.

Note: You are provided with access to an OCI Tenancy, an assigned compartment, and OCI credentials. Throughout your exam, ensure to use the assigned Compartment 99234021-C01 and Region us-ashburn-1.

Complete the following task in the OCI environment provisioned:

Create a new VCN with the name PBT_SECRET_VCN01 and public subnet within your assigned compartment.

Complete the following tasks in the OCI environment provisioned:

• Create a Linux Instance with the name [Provide Name Here] within the compartment.

Provide your own public key to SSH the instance.
