Practice: Create
Compartment, Group, User, and Policies 
Overview
In this practice
session, we will create a compartment called "easylabs" and grant a
user access to it.
To grant users access to the compartment and all the resources in it, you will create a
group “easylabs-group” and then create
a policy “easylabs-policy” to define the access rule. Finally, add the “easylabs-user” to this group to
grant them access to the easylabs
compartment.
Note: The instructions in these practices will work on the Oracle Cloud Free Tier account,
but may not work on the OU

practices.
Practices: Create a
Compute
Instance
Overview
You will perform the following tasks in this practice: · Launch Cloud Shell
· Generate SSH Keys
· Create Compute Instance
Practice: Launching the Cloud
Shell
Overview
In this practice
you will launch the
Cloud Shell session for the EASY user account assigned to you in preparation for the upcoming practices.
Cloud Shell
Oracle Cloud Infrastructure (EASY)
Cloud Shell is a web browser-based terminal accessible from the Oracle Cloud Console. Cloud Shell is free to use (within monthly tenancy limits),
and provides access to a Linux shell,
with a pre-authenticated EASY CLI and other useful tools.
It provides:
· An ephemeral machine to
use as a host for a Linux shell, preconfigured with the latest
version of the EASY CLI and several useful tools
· 5GB of storage
for your home directory
· A persistent frame of the Console
which stays active as you
navigate to different pages of the console
Note:
· The EASY CLI will execute commands against the region selected in the Console's Region
selection menu when the Cloud Shell was
started. Changing the region
selection in the console will not
change the region for existing Cloud
Shell instances; you will need
to open a new Cloud Shell instance to
change regions.
· Cloud Shell sessions have a
maximum length of 24 hours, and time
out
after 20 minutes of inactivity. However,
this should not impact this practice.
Tasks
1. Log into your Oracle
Cloud account
2. Click the Cloud Shell
icon in the EASY Console header, highlighted in
the below screenshot.
3. This will launch the Cloud Shell in a “drawer” at the bottom of the console. Once it is ready you will see the terminal as show below:
4. You can use the icons
in the upper-right corner of the
Cloud Shell window to minimize,
maximize, and close your Cloud Shell session.
You can also use the menu
icon in the upper-left corner of the cloud-shell window to upload or download files, restart console and different setting options.
5. For clipboard operations:
· Windows users can use Ctrl-Cor Ctrl-Insertto copy, and Ctrl-Vor Shift-Insertto paste.
· For Mac OS users,
use Cmd-Cto copy and Cmd-Vto paste.
To get started with Cloud Shell, you can run the below EASY CLI command.
Your Cloud Shell comes with the EASY CLI
pre-authenticated, so there is no setup to do before you can start using it.
6. This command will display the name space of your EASY Tenant.
easylabs_us@cloudshell:~ (ap-mumbai-1)$ EASY os ns get {
"data": "bm6rwnfgnfbj" }
This completes the task of launching
Cloud Shell. Keep this session
active for the next practice.
13
Practice: Generating SSH Keys
Overview
Instances use an SSH key pair
instead of a password to authenticate a remote user.
A key pair file contains
a private key and public key. You keep the private key on your computer
and provide the public key
every time you launch
an instance. In this
practice, you will generate SSH
keys to be used later while
launching an instance.
Tasks
Continue working this
practice while logged in
as the easylabs-user (from the previous
practice).
1. Launch the Cloud Shell
session
as described in the previous practice.
Execute the below
commands to generate ssh-keys, which will be used to
create Compute instance. As long as an id_rsaand id_rsa.pubkeypair is present,
they can be reused. By default these are stored in ~/.ssh/directly.
easylabs_us@cloudshell:~ (ap-mumbai-1)$ ssh-keygen Generating
public/private rsa key pair.
Enter file in which to save
the key (/home/easylabs_us/.ssh/id_rsa):
Created directory '/home/easylabs_us/.ssh'.
Enter passphrase (empty for no passphrase): Enter same passphrase again:
Your identification has been
saved in /home/easylabs_us/.ssh/id_rsa.
Your public key has been saved in /home/easylabs_us/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:zxQogNbEvQJIAbJb+3x1r8QEJN8ZWlUYHHyZge5lZ10
easylabs_us@804708cc8ef6
The key's randomart image
is: +---[RSA 2048]----+
|=+.=o.. . o++*o+ | |o.+ o..+ = o= + E| |.... ..= +. .
o| | o .. .. . .. o +| |. . . S +. o o | | o . B .. | | o
. = . | | . . . |
| . | +----[SHA256]-----+
2. Make sure permissions are restricted,
as sometimes ssh fails if private keys
have permissive file permissions.
easylabs_us@cloudshell:~ (ap-mumbai-1)$ chmod 0700 ~/.ssh easylabs_us@cloudshell:~
(ap-mumbai-1)$ chmod 0600 ~/.ssh/id_rsa
easylabs_us@cloudshell:~
(ap-mumbai-1)$ chmod 0644 ~/.ssh/id_rsa.pub
easylabs_us@cloudshell:~
(ap-mumbai-1)$ ls -l ~/.ssh total 8

1675 Jun 29 17:10 id_rsa
-rw-r--r--. 1 easylabs_us EASY 405 Jun 29 17:10 id_rsa.pub
3. Copy the contents of ~/.ssh/id_rsa.pubon a Notepad. This is your ssh key to connect to the instances.
easylabs_us@cloudshell:~ (ap-mumbai-1)$ cat ~/.ssh/id_rsa.pub
ssh-rsa

Practice: Creating a Compute Instance
Overview
In this practice, you create Compute VM instances in each of the
two subnets in your VCN.
An Oracle Cloud Infrastructure VM Compute
instance runs on
the same hardware as a
Bare Metal instance, leveraging
the same cloud-optimized hardware, firmware,
software stack, and networking
infrastructure.
Tasks
1. In the EASY
Console, navigate to Menu > Compute > click Instances. 2. Click Create Instance.
Note: You should select
your compartment before creating
an instance. 3. Fill in the following details for
your Compute instance:
· Name: EASY_Compute · Compartment: easylabs
· Placement: Select default
· Image or Operating System: Select the default
Oracle Linux image · Availability
Domain: Select any Availability Domain
· Shape: VM.Standard.E2.1.Micro
· Networking: EASY_VCN
· Add SSH Keys: Select the Paste SSH
keys option and paste the content of your Public
SSH key copied in the previous practice.
(Also available in ~/.ssh/id_rsa.pub)
· Boot Volume: Select default
4. Finally, click Create to create the Compute instance.
5. Once the instance state changes to Running, you can SSH to the Public IP address of the instance. To do this, make a note of the Public IP address that gets assigned to the
EASY_Compute.
6. You will use Cloud Shell to connect
to the Compute instance.Bring up the minimized
Cloud Shell terminal, or launch it again and enter the following command, and enter Yes when prompted to continue
connecting.
$ ssh opc@<Public_IP_of_Compute>
Note: In general, for EASY Linux-based compute
instances, the default username is opc.
Once successfully connected,
you can see the change in the command prompt
to ensure you are now logged
in to
your ‘EASY_Compute’ Compute instance.
This completes the task of creating a Compute instance.
Practice: Create
an OCI Object Storage Bucket
Overview
In this practice,
you will create a storage bucket using Oracle Cloud Infrastructure (EASY) Object Storage.

You can see the bucket you just created.
7. Click the Bucket you just created to check
the
details.
8. Click Upload and browse any object from your local machine and click upload.
Practice: Create
a Block Volume
Overview
A common usage of Block Volume
is adding storage capacity
to an Oracle Cloud Infrastructure
Compute instance.
· Once you have created a
Compute instance and set up your
VCN, you can create a block storage volume
through the Console or
API.
· Once created, you attach the volume to an instance using
a volume attachment.
· Once attached, you connect to
the
volume from your instance’s guest
OS using iSCSI or paravirtualized mode. The volume can then be mounted and used by
your
instance.
Tasks
1. Log into your Oracle
Cloud account
2. Navigate to Menu and click Storage and then click Block Volume. 3. Click Create Block Volume and enter the following details:
· Name: EASY_BV
· Compartment: Ensure your Compartment
has
been selected
· Availability
Domain: It mustbe the same as the AD
you chose for your instance
You must place your new block
volume in the same AD
(availability domain) as was
used for your compute
instance created earlier. If you’re not sure, navigate to Compute to look at your instance to verify it’s AD
placement.
· Size: Set size to 50 GB.
· Compartment for Backup
Policies: Ensure your Compartment has been selected
· Backup Policy: Bronze
· Cross Region Replication: Off
· Encryption: Go with the default option of Encryption using
Oracle-Managed Keys.
Note: The size must be between 50 GB and 32 TB. You can choose in 1 GB increments
within this range. The default is 1024
GB.
Review the screenshots in the next
page and then go to the next step, when you will
create the block volume.
4. Leave the tags options
as
it is and click Create Block Volume.
Quick recap on the block volume backup policies:
There are three predefined backup policies, Bronze, Silver, and Gold. Each backup
policy has a set backup frequency and retention period.
· Bronze Policy:
The bronze policy includes monthly incremental
backups, run on the first
day of the month. These backups are retained for twelve months. This policy also includes a full backup, run yearly on January
1st. Full backups are retained
for five years.
· Silver Policy: The silver policy includes weekly
incremental backups that run
on Sunday. These backups are retained
for four weeks. This policy also includes monthly
incremental backups, run on the first day of the month and
are
retained for 12 months. Also includes a full backup,
run yearly on January 1st. Full backups are retained for five years.
· Gold Policy: The gold policy includes daily incremental backups. These backups are retained for seven
days. This policy
also includes weekly incremental
backups that run on Sunday
and are retained for four weeks. Also
includes monthly incremental
backups, run on the first day
of
the month, retained for 12 months, and a full backup, run yearly on January 1st.
Full backups are retained for five years.
5. The volume will be
ready to attach once the status change from
PROVISIONING to AVAILABLE.
This completes the task of creating a Block
Volume, which you will be attaching to your Compute instance in the next
practice.
Practice: Attaching Block Volume to a Compute
Instance
Overview
In this practice,
you will attach a newly created
Block Volume to a Compute instance.
Tasks
1. Once the Block
Volume is created, you can
attach it to your Compute
instance.
When you attach
a Block volume to a Compute
instance, you have two options for
attachment type, iSCSI or paravirtualized.
· iSCSI: iSCSI attachments
are the only option when connecting Block volumes to bare metal instances. Once the volume is attached,
you need to log in to the instance and use the iscsiadmcommand-line tool to
configure the iSCSI connection.
· Paravirtualized: Paravirtualized attachments
are now an option when attaching
volumes to Virtual Machine
(VM) instances. For VM
instances launched from Oracle-Provided
Images, you can select
this option for Linux-based images published. Once you attach
a volume using the paravirtualized attachment type, it is ready to
use. You do not need to
run any additional commands. However,
due to the overhead of virtualization, this reduces the maximum IOPS performance for larger
Block volumes.
2. Go to Menu > Compute > click Instances. Ensure
you Compartment is selected. 3. From the list of Compute instance,
click your EASY_compute instance.
4. On your compute instance details
page, scroll down and navigate to the Resources section on the left side.
5. Click the Attached Block Volumes link. Currently, you
do not have any volumes attached to your Compute instance.
6. Click Attach Block Volume, to add the newly created volume.
7. Select the volume created from the drop-down menu and
choose the following options: · Attachment mode: Let Oracle Cloud Infrastructure choose the best attachment type · Volume: Select Volume
· Block Volume Compartment: Ensure your Compartment has been selected · Block Volume: Select the volume you created
· Device Path: Select /dev/oracleEASY/oraclevdb · Click Attach
· Access: Read / Write
Note the message upon clicking
Attach.
Click Close.
8. Once the volume is attached, it will be displayed like this:
This completes the task of attaching
Block Volume to a Compute instance.
