Hello.
Welcome to this video demonstrating how to create Oracle Autonomous Linux instances in
Oracle Cloud Infrastructure.
Oracle Autonomous Linux is an Oracle Cloud Infrastructure image that is available for
no additional charge.
Oracle Autonomous Linux requires no user intervention and is integrated with the OS Management service
to automatically manages the instance.
It integrates features for automated operating system management, event notification, and
unattended patching.
Daily package updates and patches, and security patches, are applied automatically.
The OS Management service works with the instance to provide notification of system crashes
and update events.
For Oracle Autonomous Linux instances created using the platform image available from August
2021 onwards, the service integrates its package, security and bug updates, as well as critical
event tracking and monitoring to now also work with Autonomous Linux instances and their
automated Ksplice updates to the system.
Before working with Oracle Autonomous Linux, the OS Management service must already be
set up. This requires appropriate policies to be enabled at tenancy or compartment level
to allow for the updating of software and reporting of key events for the instances.
You can find out more information about Autonomous Linux in Oracle Cloud Infrastructure at this
documentation link.
So lets create an Oracle Autonomous Linux instance.
Clicking on Create Instance launches the instance creation dialog.
I'll give the instance the name mor-alx-20.
And for the administrative domain for the instance, here I select AD 3.
Scrolling down to the Image and shape section, we will choose the standard Oracle Autonomous
Linux image for our new instance.
We click on Change image.
The standard Autonomous Linux image is available as a platform image, so after the image selection
loads we select the image from the list.
Clicking on the Image Build drop down we see there are a few options.
Remember, to work with OS Management we must select the build 2021.08-0, the August 2021
build, or later.
We tick the box to accept the terms of use, and then click Select Image.
For this instance, and knowing the available resources in my tenancy, I select Change Shape
and pick the VM.Standard2.1 Intel shape, and confirm the choice with Select Shape.
Scrolling down to Networking, we change the compartment to the one we want to use for
the primary network, namely our virtual cloud network.
We change the compartment for our subnet to match the virtual cloud network and select
the subnet offered.
This subnet supports private IP addressing, which is what we want, so we keep Do not assign
a public IP address.
We could expand the Show advanced options to choose how to manage the DNS settings and
qualified domain name, but I am happy leave the default settings that are applied.
Scrolling down to Add SSH Keys.
For this instance we select Upload public key files, so I drop the public key file in
the key windowed section.
We are happy to keep the default Boot volume settings, so we click Create to begin the
provisioning process.
We are returned to the instance details, and after a few minutes the instance state changes
to show its running.
Selecting the Cloud Agent Tab, it populates a list of the plugins enabled on the instance
and we can see the Oracle Autonomous Linux and OS Management plugins are enabled.
Scrolling down under Resources we click on OS Management.
Initially the section displays only OS Management and kernel information, but as the OS Management
plugin starts the Autonomous Linux plugin on the instance, the section refreshes to
show the Autonomous Linux information also.
The updated section now shows the General information section and Events summary section
listing the number of system error events.
Autonomous updates indicates when the daily automatic update of kernel, packages, security
and bug fixes will be performed.
To change the time we click on Edit.
The dialog Time drop down allows us to pick a time or to type in a time we prefer.
Here we select 14:00 and Save Changes.
Soon after the time indicated automatically changes to reflect the new chosen time.
In order to be informed when the automatic updates are applied or when a system crash
event occurs, we need to apply a notification topic.
To assign the topic, we click on Edit beside Notification topic.
If there is already a topic to use, clicking the drop down shows us any notifications we
can assign.
We will leave it as None, and create a new topic.
We click the Create new topic link.
This redirects us to the Notification service in our console.
We can see two topics already created.
We select Create Topic.
I give the topic the name mor_notify_20, leave the description blank and dont need the tagging
options from the Advanced Options.
We click Create.
With the topic created, in order to get notifications from events associated with it, we need to
subscribe to it.
We click Subscriptions.
And select Create Subscription to create a new one.
From the Subscription Topic drop down list we select the topic we just created.
From the Protocol drop down, we are offered how we will receive notifications from the
topic.
We take the default Email.
In the Email field, we type in the email address which will receive the notifications.
Then click Create.
We see our subscription now listed, and marked as Pending.
An email is sent to the email address for us to accept the subscription, so until we
confirm this will remain as Pending.
Going to our email client, we see the email sent to us.
To accept the subscription, we click on the Confirm subscription link.
This opens our default browser and shows our subscription confirmed.
We have now created our Autonomous Linux instance and have set up notifications.
Updates will be automatically applied each day at the assigned time without any need
for user intervention, and we will receive emails informing us each time when the updates
occur.
We will also receive emails for any system events that occur whether the instance had
to self restart to resolve the issue.
For more in depth information of the other settings and functions managed in our console
for Autonomous Linux instances you can look at this free video which is also available.
Thats the end of the video, thanks for watching.
