+# K8S Hands-on
+
+
+
+### Verify pre-requirements
+
+- **`kubectl`** - short for Kubernetes Controller - is the CLI for Kubernetes cluster and is required in order to be able to run the labs.
+- In order to install `kubectl` and if required creating a local cluster, please refer to [Kubernetes - Install Tools](https://kubernetes.io/docs/tasks/tools/)
+
+<!-- inPage TOC start -->

+ - [02. Start minikube](#02-Start-minikube)
+ - [03. Check the minikube status](#03-Check-the-minikube-status)

+
+### 01. Installing minikube
+
+- If you don't have an existing cluster you can use google cloud for the labs hands-on
+- Click on the button below to be able to run the labs on Google Shell <br/>
+  **[Use: <kbd>CTRL + click to open in new window]**  
+  [![Open in Cloud Shell](https://gstatic.com/cloudssh/images/open-btn.svg)](https://console.cloud.google.com/cloudshell/editor?cloudshell_git_repo=https://github.com/seifrajhi/Kubernetes-practical-exercises-Hands-on&cloudshell_workspace=KubernetesLabs&cloudshell_open_in_editor=README.md)
+
+- Run the following script in the opened terminal
+
+```sh
+# Download minikube
+curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
+
+# Install minikube
+sudo install minikube-linux-amd64 /usr/local/bin/minikube
+```
+
+### 02. Start minikube
+
+```sh
+minikube start
+```
+
+- You should see an output like this:
+
+```sh
+* minikube v1.16.0 on Debian 10.7
+  - MINIKUBE_FORCE_SYSTEMD=true
+  - MINIKUBE_HOME=/google/minikube
+  - MINIKUBE_WANTUPDATENOTIFICATION=false
+* Automatically selected the docker driver
+* Starting control plane node minikube in cluster minikube
+* Pulling base image ...
+* Downloading Kubernetes v1.20.0 preload ...
+    > preloaded-images-k8s-v8-v1....: 491.00 MiB / 491.00 MiB  100.00% 86.82 Mi
+* Creating docker container (CPUs=2, Memory=4000MB) ...
+* Preparing Kubernetes v1.20.0 on Docker 20.10.0 ...
+  - Generating certificates and keys ...
+  - Booting up control plane ...
+  - Configuring RBAC rules ...
+* Verifying Kubernetes components...
+* Enabled addons: default-storageclass, storage-provisioner
+* Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
+```
+
+### 03. Check the minikube status
+
+```
+minikube status
+```
+
+- You should see output similar to this one:
+
+```
+minikube
+type: Control Plane
+host: Running
+kubelet: Running
+apiserver: Running
+kubeconfig: Configured
+timeToStop: Nonexistent
+```
+
+### 04. Verify that the cluster is up and running
+
+```sh
+$ kubectl cluster-info
+
+Kubernetes control plane is running at https://192.168.49.2:8443
+KubeDNS is running at https://192.168.49.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
+```
+
+- Verify that `kubectl` is installed and configured (You should get something like the following)
+
+```sh
+kubectl config view
+```
+
+```yaml
+apiVersion: v1
+clusters:
+  - cluster:
+      certificate-authority: /google/minikube/.minikube/ca.crt
+      server: https://192.168.49.2:8443
+    name: minikube
+contexts:
+  - context:
+      cluster: minikube
+      namespace: default
+      user: minikube
+    name: minikube
+current-context: minikube
+kind: Config
+preferences: {}
+users:
+  - name: minikube
+    user:
+      client-certificate: /google/minikube/.minikube/profiles/minikube/client.crt
+      client-key: /google/minikube/.minikube/profiles/minikube/client.key
+```
+
+### 05. Verify that you can "talk" to your cluster
+
+```sh
+# In this sample we have minikube pod running
+$ kubectl get nodes
+NAME       STATUS   ROLES                  AGE    VERSION
+minikube   Ready    control-plane,master   3m9s   v1.20.0
+```
+
+### 05.01. Verify that you can "talk" to your cluster
+
+```sh
+# In this sample we have minikube pod running
+$ kubectl get nodes
+NAME       STATUS   ROLES                  AGE    VERSION
+minikube   Ready    control-plane,master   3m9s   v1.20.0
+```

+# Namespaces
+
+- Kubernetes supports **multiple virtual clusters** backed by the same **physical cluster**.
+- These virtual clusters are called namespaces.
+- Namespaces are the default way for Kubernetes to separate resources.
+- Using name spaces we can isolate the development, improve security and more.
+- Kubernetes clusters has a build in namespace called **default** and might contain more namespaces like like `kube-system` for example.

+**<kbd>CTRL</kbd> + <kbd>click</kbd> to open in new window**
+
+---
+
+### 01. Create Namespace
+
+### 01.01. Create Namespace
+
+```sh
+# In this sample `codewizard` is the desired name space
+$ kubectl create namespace codewizard
+namespace "codewizard" created
+
+### !!! Try to create the following name space (with _ & -):
+$ kubectl create namespace my_namespace-
+```
+
+### 02. Setting the default Namespace for `kubectl`
+
+- To set the default namespace run:
+
+```sh
+$ kubectl config set-context $(kubectl config current-context) --namespace=codewizard
+
+Context minikube modified.
+```
+
+### 03. Verify that you've updated the namespace
+
+```sh
+$ kubectl config get-contexts
+CURRENT     NAME                 CLUSTER          AUTHINFO         NAMESPACE
+            docker-desktop       docker-desktop   docker-desktop
+            docker-for-desktop   docker-desktop   docker-desktop
+*           minikube             minikube         minikube         codewizard
+```
+
+### Note:
+
+- When using `kubectl` you can pass the `-n` flag in order to execute the `kubectl` command on a desired namespace
+- For example:
+
+```sh
+# get resources of a specific workspace
+$ kubectl get pods -n <namespace>
+```
