Mastering Kubernetes Across Cloud Platforms

Wanderson Silva has embarked on his 8th postgraduate program, this time focusing on Cloud Services with an emphasis on Kubernetes at FETES – Faculdade de Educação e Tecnologia do Espírito Santo. His goal is to master Kubernetes across major cloud platforms like Azure, AWS, GCP, and DigitalOcean. This article delves into the essentials of Kubernetes and provides practical commands and steps to get started.

You Should Know:

1. Setting Up Kubernetes on Azure:

Install Azure CLI:

curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

Create a Kubernetes cluster:

az aks create --resource-group myResourceGroup --name myAKSCluster --node-count 1 --enable-addons monitoring --generate-ssh-keys

2. Deploying Kubernetes on AWS:

Install AWS CLI:
```
sudo apt install awscli
```
Configure AWS CLI:
```
aws configure
```

Create an EKS cluster:

eksctl create cluster --name my-cluster --region region-code --nodegroup-name my-nodes --node-type t2.micro --nodes 2

3. Kubernetes on Google Cloud Platform (GCP):

Install Google Cloud SDK:
```
sudo apt-get install google-cloud-sdk
```
Initialize the SDK:
```
gcloud init
```

Create a Kubernetes cluster:

gcloud container clusters create my-cluster --num-nodes=3 --zone=us-central1-a

4. Kubernetes on DigitalOcean:

Install doctl (DigitalOcean CLI):
```
sudo snap install doctl
```
Authenticate doctl:
```
doctl auth init
```

Create a Kubernetes cluster:

doctl kubernetes cluster create my-cluster --region nyc1 --size s-1vcpu-2gb --count 3

5. Basic Kubernetes Commands:

Check cluster status:
```
kubectl cluster-info
```
List nodes:
```
kubectl get nodes
```

Deploy an application:

kubectl create deployment my-app --image=my-app-image

Expose the application:

kubectl expose deployment my-app --type=LoadBalancer --port=80

What Undercode Say:
