Task 1: Create a Bucket in Object Storage

Create a bucket named CloudOpsBucket_  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@

4. In the compute instance, create the bucket with the following command (note that it’s one long line):

oci os bucket create -c "" --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

Task 1(a): Develop the cloud-init Script:

Create a compute instance pbt_cloud_init_vm_01 with the following properties:

Shape: VM.Standard.A1.Flex instance with 1 OCPU and 6 GB memory

Image: Oracle Linux 8

Placement: Use any of the availability domains

Network:

Place in the public subnet Cloud-Init Challenge SNT

Assign a public IPv4

Use the SSH public key

Add a cloud-init script and perform the following:

Use yum or dnf to install httpd.

Use systemctl to enable and start httpd

Open the firewall to https:

sudo firewall-offline-cmd --add-service=http

systemctl restart firewalld

Mark Complete

Task 1(b): Use cloud-init to Configure Apache on Instances in an Autoscaling Instance Pool:

You're deploying an Apache-based web application on OCI that requires horizontal autoscaling.

To  configure instances upon provisioning, write a cloud-init script for  Oracle Linux 8 that installs and enables Apache (httpd), and opens the  firewall for HTTP on TCP port 80. Create an instance configuration and  include the cloud-init script in it. Use this instance configuration to  create an instance pool and autoscaling configuration.

Task 2: Create an Autoscaling Instance Pool Including the cloud-init Script:

Create an instance configuration named pbt_cloud_init_config_01 with the following properties:

Shape: VM.Standard.A1.Flex instance with 1 OCPU and 6 GB memory

Image: Oracle Linux 8

Placement: Use any of the availability domains

Network:

Place in the public subnet Cloud-Init Challenge SNT

Assign a public IPv4

Use the SSH public key

Attach the cloud-init script created in Task 1

Create  an instance pool named pbt_cloud_init_pool_01 with one instance by  using the instance configuration pbt_cloud_init_config_01

Create and attach an autoscaling configuration named pbt_cloud_autoscaling_config_01 with the following settings:

Metric-based autoscaling

Cooldown: 300 second

Performance metric: CPU utilization

Scale-out rule:

Operator: Greater than (>)

Threshold: 75%

Number of instances to add: 1

Scale-in rule:

Operator: Less than (<)

Threshold: 25%

Number of instances to remove: 1

Scaling limits:

Minimum number of instances: 1

Maximum number of instances: 2

Initial number of instances: 1
