Oracle Cloud Infrastructure- Create VCN + Compute Ubuntu Linux 18.04

In this post, I'll demonstrate how to create a new VCN (Virtual Cloud Network) with Internet Gateway+ NAT Gateway + Service Gateway followed by the creation of a new compute instance with Ubuntu 18.04.EnvironmentIn order to create a new compute instance in oracle cloud, there are few prerequisites-A valid OCI accountA virtual Cloud networkOptional SSH keys in case you want your own keys to be usedBelow is the network diagram of the virtual cloud network with the schematic wizard provided by OCI for quick setup of a VCN-
Steps to achieveSo, let's login to your OCI console and navigate to Networking >> Overview from the left navigation panel. From the right-side panel, click on start VCN wizard as shown below-
This will open a web form to provide basic details like- VCN name and rest of the things are provided as default as shown below-
Further, click on next and the Create. Once created, the VCN details look as shown below.
So, this way our VCN is ready. We should now move to…

Oracle Cloud Infrastructure- Changing root partition of Oracle Linux instance 7.8

In this post, I'll describe a problem in OCI with respect to storage extension and possible solution with stepwise implementation process.ScenarioI have provisioned a new compute instance with a default setting including the boot volume size of OCI i.e.  46.6 GB. The partition available to root ( / ) became ~39 GB post OS installation. 
Requirement A requirement came where I need at least 100GB in my root ( / ) so the installation of that necessary production should go under respective directories viz. /opt or /u01 etc. 
ApproachI have figured out two approaches- Increase the boot volume size to a higher value and use Linux growpart to increase the size for root ( / ).Attach a new block volume with required capacity and mount it to required location viz  /opt or /u01 etc.  SolutionThis article considers the first approach. For the second approach, check out my this post with necessary steps as a subpart of the post.
Steps- Login to OCI consoleNavigate to the compute instancesStop the…

Oracle Cloud Infrastructure- Adding a block volume and use it for swap

Hello everyone, this is my first blog on Oracle Cloud Infrastructure.RequirementTo increase Swap of existing compute instance with a new block volume in OCI.
PrerequisiteA valid OCI account with available credits Steps to Achieve 1. Create a new block volume 550GB 2. Attach the block volume to the instance 3. Execute iscsi commands and verify the disk attachment provided by OCI ls -l /dev/orcleoci/ 4. Do partitioning of the disk to 120GB for swap Making the swap partition of required space 120GB
fdisk <NEWLY_ADDED_DISK> Command (m for help): n Partition number (1-4): 2 Command (m for help): t Hex code (type L to list codes): 82 Command (m for help): w ls -l /dev/orcleoci/
