How to install and Set Up kubectl on Linux

Install kubectl binary with curl on Linux

Download the latest release with the command:
```
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
```
Note:
To download a specific version, replace the $(curl -L -s https://dl.k8s.io/release/stable.txt) portion of the command with the specific version.

For example, to download version v1.25.0 on Linux, type:
```
curl -LO https://dl.k8s.io/release/v1.25.0/bin/linux/amd64/kubectl
```
Validate the binary (optional)

Download the kubectl checksum file:
```
curl -LO "https://dl.k8s.io/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl.sha256"
```
Validate the kubectl binary against the checksum file:
```
echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check
```
If valid, the output is:
```
kubectl: OK
```
If the check fails, sha256 exits with nonzero status and prints output similar to:
```
kubectl: FAILED
sha256sum: WARNING: 1 computed checksum did NOT match
```
Note: Download the same version of the binary and checksum.

Install kubectl

sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

Note:

If you do not have root access on the target system, you can still install kubectl to the ~/.local/bin directory:

chmod +x kubectl
mkdir -p ~/.local/bin
mv ./kubectl ~/.local/bin/kubectl
# and then append (or prepend) ~/.local/bin to $PATH

Test to ensure the version you installed is up-to-date:
```
kubectl version --client
```
Or use this for detailed view of version:
```
kubectl version --client --output=yaml   
```
