Extending Your EBS Volume in Linux AWS EC2

First you have to select the EBS volume >> Actions >> Modify Volume .

Now select the total volume that you want to increase to in the size section.

Now click on the Modify button.

Now finally do the below steps after login to the server for extending the additionally allocated space.

# df -h  >> This will show you the Filesystem like '/dev/xvda1'.

Expand the modified partition using growpart (note that you need to add a space between the device name and the partition number):

# sudo growpart /dev/xvda 1 
# sudo growpart /dev/nvme0n1 1  >> for /dev/nvme0n1p1
A look at the lsblk output confirms that the partition /dev/xvda1 now fills the available space on the volume:

 # root@logserver:~# lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0  40G  0 disk 
└─xvda1 202:1    0  40G  0 part /


To extend a Linux file system

# resize2fs /dev/xvda1 

# resize2fs /dev/nvme0n1p1

K8s External Secrets integration between AWS EKS and Secrets Manager(SM) using IAM Role.

What is K8s External Secrets and how it will make your life easier? Before saying about External Secrets we will say about k8s secrets and how it will work. In k8s secrets we will create key value pairs of the secrets and set this as either pod env variables or mount them as volumes to pods. For more details about k8s secrets you can check my blog http://jinojoseph.blogspot.com/2020/08/k8s-secrets-explained.html   So in this case if developers wants to change the ENV variables , then we have to edit the k8s manifest yaml file, then we have to apply the new files to the deployment. This is a tiresome process and also chances of applying to the wrong context is high if you have multiple k8s clusters for dev / stage and Prod deployments. So in-order to make this easy , we can add all the secrets that is needed in the deployment, in the AWS Secret Manager and with the help of External secrets we can fetch and create those secrets in the k8s cluster. So what is K8s external Secret? It i...

Setting /etc/hosts entries during the initial deployment of an Application using k8s yaml file

Some times we have to enter specific hosts file entries to the container running inside the POD of a kubernetes deployment during the initial deployment stage itself. If these entries are not in place, the application env variables mentioned in the yaml file , as hostnames , will not resolve to the IP address and the application will not start properly. So to make sure the /etc/hosts file entries are already there after the spin up of the POD you can add the below entries in your yaml file. cat > api-deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: spec:   template:     metadata:     spec:       volumes:       containers:       - image: registryserver.jinojoseph.com:5000/jinojosephimage:v1.13         lifecycle:           postStart:             exec:               command:...
