Terraform alias is a feature that allows you to manage resources across multiple regions more efficiently. It enables you to define different configurations for resources in various regions while using the same Terraform codebase. Here's a simple example to illustrate how to use Terraform alias for multiple regions:

provider "aws" {
  alias  = "us_east"
  region = "us-east-1"
}

provider "aws" {
  alias  = "us_west"
  region = "us-west-1"
}
resource "aws_instance" "example" {
  provider      = aws.us_east
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
}

resource "aws_instance" "example_west" {
  provider      = aws.us_west
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
} 

In this example, we define two different AWS providers with aliases us_east and us_west, representing the US East and US West regions, respectively. Then, we create instances using these providers, specifying the region-specific provider for each instance. This allows Terraform to manage resources in different regions using the same configuration file. #terraform #iac

#devops #kubernetes k9s is a powerful command-line interface (CLI) tool for Kubernetes management. It allows you to interact with Kubernetes clusters efficiently, offering features like resource viewing, log access, event monitoring, and pod command execution—all from your terminal. Install k9s using Homebrew with the command brew install k9s, and access its intuitive interface by running k9s

Spread operator in JavaScript is represented by three dots (...). 
It's a useful syntax for manipulating arrays and objects in various ways.

Following are some of the use cases:-

Spread in Arrays:-

1. Copying Arrays: It allows you to create a new array by copying another array.

const originalArray = [1, 2, 3];
const copyArray = [...originalArray];
console.log(copyArray); // [1, 2, 3]


2. Concatenating Arrays: You can merge arrays together.

const array1 = [1, 2, 3];
const array2 = [4, 5, 6];
const mergedArray = [...array1, ...array2];
console.log(mergedArray); // [1, 2, 3, 4, 5, 6]

3. Adding Elements to Arrays: You can add new elements to an existing array.

const array1 = [1, 2, 3];
const newArray = [...array1, 4, 5, 6];
console.log(newArray); // [1, 2, 3, 4, 5, 6]



Spread in Objects:-

1. Copying Objects: It allows you to create a shallow copy of an object.

const originalObj = { name: 'John', age: 30 };
const copyObj = { ...originalObj };
console.log(copyObj); // { name: 'John', age: 30 }

2. Merging Objects: You can merge multiple objects into one.

const obj1 = { name: 'John' };
const obj2 = { age: 30 };
const mergedObj = { ...obj1, ...obj2 };
console.log(mergedObj); // { name: 'John', age: 30 }

3. Adding Properties to Objects: You can add new properties to an object.

const obj1 = { name: 'John' };
const newObj = { ...obj1, age: 30 };
console.log(newObj); // { name: 'John', age: 30 }



Function Arguments:

1. Spread can be used to pass an array as individual arguments to a function.

const numbers = [1, 2, 3];
const sum = (a, b, c) => a + b + c;
console.log(sum(...numbers)); // 6

#devops #kubernetes #helm To verify the Helm chart, you can use the following command: minikube service servicename This command opens a web browser and directs it to a service running in your Minikube Kubernetes cluster. It simplifies accessing and testing applications deployed locally on Minikube.

git switch -c branch_name used in Git to create and switch to a new branch in one step. #gitcommand

The helm search hub <keyword> command is used to search for charts available in the Helm Hub, which is a centralized repository of Helm charts , keyword can be prometheus, grafana, nginx, postgresql etc. helm search hub <keyword> --max-col-width=0 this command displays the results without column width limitations. #devops #helm #helmhub #kubernetes

Empty a file using the > symbol. Simply typing > filename truncates the file, removing all its previous content. #UnixCommand

chmod 777 <filename> is a command used to set permissions on a file or directory in Unix-like operating systems (including Linux and macOS). It grants full read, write, and execute permissions. #devops #FilePermissions

Kubernetes on Docker Desktop • Install Docker Desktop • Enable Kubernetes from docker-desktop setting • Switch the Kubernetes context to docker-desktop • Example :

❯ kubectl config get-contexts
CURRENT   NAME                      CLUSTER                   AUTHINFO                  NAMESPACE
          docker-desktop            docker-desktop            docker-desktop
*         kind-kube-nginx-cluster   kind-kube-nginx-cluster   kind-kube-nginx-cluster

❯ kubectl config use-context docker-desktop
Switched to context "docker-desktop".

• Instead of using the command kubectl config use-context docker-desktop we can also go with kubectx to switch between Kubernetes context • To install kubectx on Mac: brew install kubectx #devops #kubernetes #dockerdesktop
