Terminating a AWS EC2 Instance #devops #aws
If the Instance is no longer in use and has been stopped, it is necessary to proceed with terminate the Instance. This step ensures that we free up resources, reduce potential security risks, and maintain a clean and efficient infrastructure.
Checklist:
- Take a Snapshot of the EBS Volume: ◦ It is best practice to take a snapshot of the EBS volume as a backup before decommissioning the service.
- Verify Terraform Management: ◦ Check if the service is managed by Terraform.
- Terminate the Instance

Recently I came across an interesting use case of combining CSS variables with environment variables. The challenge was to change a CSS property, particularly a color, based on an environment variable. Since CSS doesn't support environment variables directly, here's the approach I took:
The global css file:
:root {
/* ----- fallback value ----- */
--primary-color: #3498db;
}
h1 {
color: var(--primary-color);
}
Then, in our React application:
const App = () => {
const primaryColor = process.env.NAME === 'a' ? '#fff' : '#000';
return (
<div style={{ '--primary-color': primaryColor }}>
<h1>Hello, World!</h1>
</div>
);
};

Using choice
Input in GitHub Actions
Choice input in Github actions can be used to provide a predefined list of options for workflow dispatch events. This makes it easier for users to select from a set of valid options when triggering workflows manually.
Example:
name: Example Workflow

workflow_dispatch:
inputs:
environment:
description: 'Select the environment'
required: true
default: 'sandbox'
type: choice
options:
- sandbox
- uat
- production
jobs:
example_job:
runs-on: ubuntu-latest
steps:
- name: Display Inputs

Key difference between App router and Page router :
App Router:
• File-based routing: Uses nested folders to define routes.
• Components: Server Components by default.
• Data fetching: Uses fetch
function.
• Layouts: Can be nested and dynamic.
• Dynamic routes: Supported, but syntax differs.
• Client-side navigation: Supported with router.push
.
• Priority: Takes precedence over Page Router.
Page Router:
• File-based routing: Files directly represent routes.
• Components: Client Components by default.
• Data fetching: Uses getServerSideProps
, getStaticProps
, getInitialProps
.
• Layouts: Static.
• Dynamic routes: Supported.
• Client-side navigation: Supported with Link
component.
• Priority: Fallback if no matching route in App Router.
