Question 3
SIMULATION
Scenario: 3 (Use the OCI CLI to Work with Object Storage from a Compute Instance) Scenario Description: (Hands-On Performance Exam Certification) Your company runs a web application in OCI that generates log files. You want to upload these files to OCI Object Storage to meet data retention requirements. Some files need to be retained indefinitely, whereas others can be deleted after 30 days. Use the OCI CLI to create bucket and upload the log directory and create a lifecycle policy rule to delete temporary files after 30 days.
Pre-Configuration:
To fulfill this requirement, you are provided with the following:
Access to an OCI tenancy, an assigned compartment, and OCI credentials
A compute instance with OCI CLI installed and a set of files in ~/dir_to_upload to use Access to the OCI Console Required IAM policies Assumptions:
Perform the tasks by using the OCI CLI on the compute instance.
Use instance principal authentication for all CLI commands; the instance has been given the policies necessary.
Connect to the compute instance using Cloud Shell's private networking and the provided SSH key.
An SSH key pair has been provided to you for the compute instance.
Private Key https://objectstorage.us-ashburn-1.oraclecloud.com/n/tenancyname/b/PBT_Storage/o/PKey.key Note: Throughout your exam, ensure to use assigned Compartment , User Name and Region.
Complete the following tasks in the provisioned OCI environment:
Task 1: Create a Bucket in Object Storage
Task 2: Upload a Directory's Contents to Object Storage
Task 3: Add a Lifecycle Policy to the Bucket

Complete the following tasks in the provisioned OCI environment:
Task 1: Create a Bucket in Object Storage
Task 2: Upload a Directory's Contents to Object Storage
Task 3: Add a Lifecycle Policy to the Bucket
Correct Answer:
See the solution below with Step by Step Explanation
Explanation:
Task 1: Create a Bucket in Object Storage
Create a bucket named CloudOpsBucket_<user id> with the following properties:
Storage tier: Standard
Auto-tiering: Disabled
Object versioning: Enabled
Emit events: Disabled
Keys: Oracle-managed
Visibility: Private
Task 2: Upload a Directory's Contents to Object Storage
Upload the contents of the directory ~/dir_to_upload and its subdirectories to the bucket CloudOpsBucket Task 3: Add a Lifecycle Policy to the Bucket Create a lifecycle policy rule that deletes all files from ~/dir_to_upload/temp after 30 days Task 1: Create a bucket in Object Storage
1. Open Cloud Shell in the console. Under Network along the top, select Ephemeral Private Network Setup.
2. Select the subnet of the compute instance.
3. SSH into the compute instance using the provided SSH key:
ssh -i /path/to/key opc@<private_ip>
4. In the compute instance, create the bucket with the following command (note that it's one long line):
oci os bucket create -c "<compartment_id>" --name "CloudOpsBucket" --auth instance_principal --versioning 'Enabled' Task 2: Upload a directory's contents to Object Storage
1. Upload the contents of the specified directory and subdirectories with the following command (note that it's one long line):
oci os object bulk-upload -bn "CloudOpsBucket" --src-dir "~/dir_to_upload" --auth instance_principal Task 3: Add a lifecycle policy to the bucket
1. Create a file named rule.json
2. Add the following content to rule.json:
{"items": [{"action": "DELETE","is-enabled": true,"name": "Delete-Rule","object-name-filter": {"exclusion-patterns": null,"inclusion-patterns": null,"inclusion-prefixes": ["temp/"]},"target": "objects","time-amount": 30,"time-unit": "DAYS"}]}
3. Add the lifecycle policy rule with the following command:
oci os object-lifecycle-policy put -bn "CloudOpsBucket" --from-json file://rule.json --auth instance_principal Top of Form
