Connect to AKS cluster nodes

Posted on by Osama Mustafa in Azure, Cloud

sometimes you need to access AKS worker node to troubelshoot, but how to do that with AKS

Run the below command

kubectl get nodes

Output will give an idea about the worker nodes you have

Run a container image on the node by issuing the kubectl debug command in order to establish a connection to it. The following command begins the process of connecting to a privileged container that has been started on your node.

kubectl debug node/<node-name-you-wish-to-connect> -it --image=mcr.microsoft.com/dotnet/runtime-deps:6.0

AWS Infrastructure

Posted on by Osama Mustafa in AWS, Cloud

The AWS Global Cloud Infrastructure is the most secure, extensive, and reliable cloud platform, offering over 200 fully featured services from data centers globally.

AWS Data Center

AWS pioneered cloud computing in 2006 to provide rapid and secure infrastructure. AWS continuously innovates on the design and systems of data centers to protect them from man-made and natural risks. Today, AWS provides data centers at a large, global scale. AWS implements controls, builds automated systems, and conducts third-party audits to confirm security and compliance. As a result, the most highly-regulated organizations in the world trust AWS every day.

Availability Zone – AZ

An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. Availability Zones are multiple, isolated areas within a particular geographic location. When you launch an instance, you can select an Availability Zone or let AWS choose one for you. If you distribute your instances across multiple Availability Zones and one instance fails, you can design your application so that an instance in another Availability Zone can handle requests.

Region

Each AWS Region consists of multiple, isolated, and physically separate Availability Zones within a geographic area. This achieves the greatest possible fault tolerance and stability. In your account, you determine which Regions you need. You can run applications and workloads from a Region to reduce latency to end users. You can do this while avoiding the upfront expenses, long-term commitments, and scaling challenges associated with maintaining and operating a global infrastructure.

AWS Local Zone

AWS Local Zones can be used for highly demanding applications that require single-digit millisecond latency to end users. Media and entertainment content creation, real-time multiplayer gaming, and Machine learning hosting and training are some use cases for AWS Local Zones.

CloudFront – Edge Location

An edge location is the nearest point to a requester of an AWS service. Edge locations are located in major cities around the world. They receive requests and cache copies of your content for faster delivery.

Create a Bastion – OCI

Posted on by Osama Mustafa in Cloud, OCI

What is a Bastion?

It’s essential to consider the security implications before allowing direct access to cloud services and resources, particularly as the latter expands. Some individuals get around this problem by setting up a virtual machine within the virtual cloud network and linking it to all the cloud services. This cuts down on publicly accessible services while facilitating connections for developers and system administrators. This virtual machine (VM) is like a manual bastion or leap box.

Create a Bastion

  • Connect to Oracle’s cloud service. To access the main menu, choose the hamburger icon in the upper left corner.
  • On the menu select “Identity & Security > Bastion”.
  • Select the compartment and click the “Create bastion” button.
  • Enter the bastion name and select the VCN and subnet for the bastion. We need to enter a CIDR block allowlist. In this case I’ve used the subnet for my IP address from my internet service provider. Click the “Create bastion” button.
  • Click on the “Create session” button.
  • Connect

Our previously copied connection information should look something like this at this point.

ssh -i  -N -L :ip-connection:22 -p 22 ocid1.bastionsession.oc1.uk-london-1.amaa...3acq@host.bastion.uk-london-1.oci.oraclecloud.com

OCI Basics – Putting Data into Object Storage OCI

Posted on by Osama Mustafa in Cloud, OCI

The Object Storage service provides reliable, secure, and scalable object storage. Object storage is a storage architecture that stores and manages data as objects. Some typical use cases include data backup, file sharing, and storing unstructured data like logs and sensor-generated data.

Creating a Bucket

  1. Open the navigation menu and click Storage. Under Object Storage, click Buckets.A list of the buckets in the compartment you’re viewing is displayed.
  2. Select a compartment from the Compartment list on the left side of the page.A list of existing buckets is displayed.
  3. Click Create Bucket.
    • Bucket Name
    • Default Storage Tier: Select the default tier in which you want to store your data
      • Standard is the primary, default storage tier Use the Standard tier for storing frequently accessed data that requires fast and immediate access.
      • Archive is the default storage tier used for archive storage, Use the Archive tier for storing rarely accessed data that requires long retention periods. Access to data in the Archive tier is not immediate. Archived data must be restored before the data is accessible.
      • Object Events: Select Emit Object Events if you want to enable the bucket to emit events for object state changes. For more information about events.
      • Encryption: Buckets are encrypted with keys managed by Oracle by default, but you can optionally encrypt the data in this bucket using your own Vault encryption key. To use Vault for your encryption needs, select Encrypt Using Customer-Managed Keys

Uploading Files to a Bucket

To upload files to your bucket using the Console:

  1. From the Object Storage Buckets screen, click the bucket name to view its details.
  2. Click Upload.
  3. In the Object Name Prefix field, optionally specify a file name prefix for the files that you plan to upload.
  4. If the Storage Tier field displays Standard, you can optionally change the storage tier to upload objects to.

Cheers
