Here are the steps to complete the challenge:

To create a new VCN with the name exam-vcn within your assigned compartment by using the Start VCN Wizard, follow these steps:

In the OCI Console, go to Networking and click Virtual Cloud Networks.

Select your assigned compartment from the list on the left.

Click Start VCN Wizard.

Select Create VCN with Internet Connectivity and click Start VCN Wizard.

Enter exam-vcn as the VCN Name and leave the other fields as default. Click Next.

Review the summary and click Create. This will create a VCN with a public subnet, a private subnet, an internet gateway, a NAT gateway, a service gateway, and a route table.

To create a new Oracle Functions application named exam-app within your assigned compartment by using the private subnet in your previously created VCN, follow these steps:

In the OCI Console, go to Developer Services and click Functions.

Select your assigned compartment from the list on the left.

Click Create Application.

Enter exam-app as the Application Name and select your previously created VCN from the VCN dropdown menu.

Select the private subnet from the Subnet dropdown menu and leave the other fields as default. Click Create. This will create an Oracle Functions application that can run serverless functions in a private subnet.

One possible IAM policy statement that allows API Gateway to access Oracle Functions in your compartment is:

ALLOW any-user to use functions-family in compartment <your-compartment-name> where ALL {request.principal.type = 'ApiGateway', request.resource.compartment.id = '<your-compartment-OCID>'}

This statement grants the any-user group the permission to use the functions-family resource type in the specified compartment, but only if the request is coming from an API Gateway and the function belongs to the same compartment as the API Gateway. For more information, see Create a Policy to Give API Gateways Access to Functions.

To create a new private repository in the Container Registry named 99248134-lab.user01/hello-python within your assigned compartment, you can follow these steps:

In the OCI Console, go toDeveloper Servicesand clickContainer Registry.

Select your assigned compartment from the list on the left.

ClickCreate Repository.

In theCreate Repositorydialog box, enter99248134-lab.user01/hello-pythonas theRepository Nameand selectPrivateas theAccessoption. You can also add a description for the repository if you want.

To complete the task of setting up the context for Fn CLI and deploying the python function to exam-app, you can follow these steps:

a. Set up the Fn CLI context in Cloud Shell - In the OCI Console, go to Developer Services and click Functions. - Select your assigned compartment from the list on the left. - Click Getting Started on the top right corner. - Copy and paste the commands from the Set Up Fn CLI Context section into the Cloud Shell window. This will create a new context for your region and compartment. - Set your registry [repo-name-prefix] by entering the following command in the Cloud Shell window:

`fn update context registry [region_key].ocir.io/[tenancy-name]/{username}`

where [region_key] is the region key for your region (for example, iad for US East Ashburn), [tenancy-name] is the name of your tenancy (for example, ocuocictrng16), and {username} is your username (for example, 99248134-lab.user01).

For example, if your region is US East Ashburn, your tenancy is ocuocictrng16, and your username is 99248134-lab.user01, your command would be:

`fn update context registry iad.ocir.io/ocuocictrng16/99248134-lab.user01`

b. Login to the registry using docker login, which will require you to generate and use an Auth Token - To generate an Auth Token, follow these steps: - In the OCI Console, open the Profile menu on the top right corner and click User Settings. - Click Auth Tokens on the left panel and then click Generate Token. - Enter a description for the token and click Generate Token. - Copy and save the token value. You will not be able to see it again later. - To login to the registry using docker login, follow these steps: - In the Cloud Shell window, enter the following command:

`docker login [region_key].ocir.io`

where [region_key] is the region key for your region (for example, iad for US East Ashburn).

For example, if your region is US East Ashburn, your command would be:

`docker login iad.ocir.io`

- Enter your username in the format `[tenancy-name]/oracleidentitycloudservice/{username}` (for example, ocuocictrng16/oracleidentitycloudservice/99248134-lab.user01) and press Enter.

- Enter your Auth Token as the password and press Enter. You should see a message saying 'Login Succeeded'.

c. Use wget https://objectstorage.us-ashburn1.oraclecloud.com/n/ocuocictrng5/b/PBT_Storage/o/ExamFunction-main.zipto upload the zip archive containing the Python function files to Cloud Shell. - In the Cloud Shell window, enter the following command:

`wget https://objectstorage.us-ashburn1.oraclecloud.com/n/ocuocictrng5/b/PBT_Storage/o/ExamFunction-main.zip`

This will download the zip archive to your current directory.

d. Extract the files by using the unzip utility and navigate to the python sub-folder - In the Cloud Shell window, enter the following commands:

`unzip ExamFunction-main.zip`

`cd ExamFunction-main/python`

This will extract the files from the zip archive and change your current directory to the python sub-folder.

e. Deploy the python function to the exam-app using an fn command - In the Cloud Shell window, enter the following command:

`fn deploy --app exam-app --local`

This will deploy the python function to the exam-app application using your local Docker image.

f. Invoke the function at least 2 times using an fn command - In the Cloud Shell window, enter the following command:

`fn invoke exam-app hellopython`

This will invoke the function and print its output.

- You can invoke the function again by repeating the same command or pressing Up Arrow and Enter keys. You should see different outputs each time you invoke the function.

To complete the task of creating a public API Gateway and invoking a private function in OCI, you can follow these steps:

To create a new public API Gateway in your compartment named exam-gateway, follow these steps:

In the OCI Console, go toDeveloper Servicesand clickAPI Gateway.

Select your assigned compartment from the list on the left.

ClickCreate Gateway.

Enterexam-gatewayas theNameand selectPublicas theType. You can also add a description for the gateway if you want.

Select your previously created VCN from theVCNdropdown menu and select any subnet from theSubnetdropdown menu. You can also enable logging for the gateway if you want.

ClickCreate. This will create a new public API Gateway in your compartment that can expose your functions to the internet.

To create a new API Deployment named exam-deployment using /v1 as the path prefix in exam-gateway, follow these steps:

In the OCI Console, go toDeveloper Servicesand clickAPI Gateway.

Select your assigned compartment from the list on the left and click on your previously created gateway (exam-gateway).

ClickDeploymentson the left panel and then clickCreate Deployment.

Enterexam-deploymentas theNameand selectFrom Scratchas theSpecification Type. You can also add a description for the deployment if you want.

Enter /v1 as thePath Prefixand leave the other fields as default. ClickNext.

To create a new route by using /hello as the path and GET as the method, follow these steps:

In the Create Deployment dialog box, clickAdd Route.

Enter /hello as thePath, select GET as theMethod, and select Oracle Functions as theType.

Select your previously created function (hello-python) from theFunction Namedropdown menu and leave the other fields as default. ClickSave Changes. This will create a new route that will invoke your function when you send a GET request to /v1/hello.

To create a new stateful CIDR Ingress Rule that allows for TCP HTTPS traffic (port 443) from all IP addresses and ports in the default Security List for exam-vcn, follow these steps:

In the OCI Console, go toNetworkingand clickVirtual Cloud Networks.

Select your assigned compartment from the list on the left and click on your previously created VCN (exam-vcn).

ClickSecurity Listson the left panel and then click on the default security list for your VCN.

ClickEdit All Rulesand then clickAdd Ingress Ruleunder the Ingress Rules section.

Enter 0.0.0.0/0 as theSource CIDR, select TCP as theIP Protocol, and enter 443 as both theSource Port Rangeand theDestination Port Range. You can also add a description for the rule if you want.

ClickSave Security List Rules. This will create a new stateful CIDR Ingress Rule that will allow HTTPS traffic from any source to reach your API Gateway.

To use curl to call the function via your API Gateway deployment, follow these steps:

In the OCI Console, go toDeveloper Servicesand clickAPI Gateway.

Select your assigned compartment from the list on the left and click on your previously created gateway (exam-gateway).

ClickDeploymentson the left panel and then click on your previously created deployment (exam-deployment).

Copy the value of the Endpoint URL field. This is the base URL for your API Deployment.

In a terminal window, enter the following command:

curl -k -X GET {deployment-endpoint}/v1/hello

where {deployment-endpoint} is the base URL that you copied.

For example, if your deployment endpoint is https://abc123xyz456.apigateway.us-ashburn-1.oci.customer-oci.com, your command would be:

curl -k -X GET https://abc123xyz456.apigateway.us-ashburn-1.oci.customer-oci.com/v1/hello

This will send a GET request to your API Deployment and invoke your function. You should see a response similar to this:

{'message': 'Hello World!'}
