Implementation steps

1. Download and install VMware fusion workstation - got free license for personal use - set bridged networking and chose wifi in the settings - adjusted vCPU to 2 (which is a requirement for installing Minikube)

2. Download and install centos VM on top of VMware (Made sure I am able to copy and paste across host and guest OS)

3. Enable no password access to the user 'osboxes' so that it doesn't prompt me to enter password every time I use sudo.

sudo visudo

osboxes         ALL=(ALL)       NOPASSWD: ALL

4. Install Docker on VMware centos

1. Ref: https://docs.docker.com/engine/install/centos/

       sudo yum install -y yum-utils
   
   sudo yum-config-manager --add-repo \
https://download.docker.com/linux/centos/docker-ce.repo

   sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
   
       sudo systemctl start docker

2. Make sure you can log into docker hub
    1. Create account in docker hub - https://hub.docker.com/
    2. Open terminal and execute following command

       docker login

5. Minikube installation

Ref: https://minikube.sigs.k8s.io/docs/start/
1. Make sure the system meets the prerequisites (such as disk space, memory)

2. #Execute following commands

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

sudo install minikube-linux-amd64 /usr/local/bin/minikube

minikube start

6. Kubectl installation -

Ref: https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/

cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1

8. Install Nginx Ingress controller using Helm chart

a. Download source code from https://github.com/kubernetes/ingress-nginx/releases/tag/helm-chart-4.1.1

b. #Expand the source code
  tar -xvzf ingress-nginx-helm-chart-4.1.1.tar.gz
  
c. #Change directory to location of charts
  cd ingress-nginx-helm-chart-4.1.1/charts/ingress-nginx
  
d. #Install nginx ingress controller package. Name the release as 'nginx'
  helm install nginx .

9. Create 2 sample deployments and expose the deployments

k create deployment web --image=gcr.io/google-samples/hello-app:1.0
k expose deployment web --type=NodePort --port=8080

k create deployment web2 --image=gcr.io/google-samples/hello-app:2.0
k expose deployment web2 --port=8080 --type=NodePort

10. Create Ingress

11. Access the hostname on browser and check logs (included as part of recording)

12. a. Install Git (on host) and Set up git repo

#create a directory
mkdir EverlyHealth

#change directory to EverlyHealth
cd EverlyHealth

#Initialize git in the current directory
git init

#Set git username and email
git config --global user.name thrisha-k
git config --global user.email [email protected]

#log into GitHub and create a repo by name 'EverlyHealth' - this helps connect the our local repo with remote repo
#Go to terminal and do the following:
git remote add origin https://github.com/thrisha-k/EverlyHealth.git

Thrishas-MacBook-Pro:EverlyHealth tkasula$ git remote -v

origin https://github.com/thrisha-k/EverlyHealth.git (fetch) origin https://github.com/thrisha-k/EverlyHealth.git (push)

c. Git push the changes

git commit -m "Adding readme.md"
git push origin master
