Let's Start our project

Step-1

Download my repositories from my github account named into to local computer:

AppCode - https://github.com/tohidhanfi20/AppCode
tf_code - https://github.com/tohidhanfi20/tf_code
kube_manifest - https://github.com/tohidhanfi20/kube_manifest

Step-2

Make all the files according to your accounts like change github credentials, Docker Credentials.

Step-3 DEEP DIVE

Now as we are provisioning Terraforma as our infra as a code firstly,
we need to change certain changes into backend.tf file present in
tf_code/ToDo-App/backend.tf for that follow this Steps :-

Go To https://signin.aws.amazon.com/
Then after you logged Navigate to s3 service.
There is a option to create a bucket Click on it.
Choose a unique name for your bucket.

Enable Versioning in those settings.
Leave all things now to default.

Step-8 START WITH THE TERRAFORM COMMANDS

Go to the directory c:\users\asus\downloads\tf_code\ToDo_App
Now write terraform init -- to initialize the terraform backend
Now use terraform plan -- to plan what resources will be created
Then use terraform apply --auto-approve

set $REGION=ap-south-1
set $CLUSTER_NAME=ToDo-App
We need to update the content of kubeconfig file with the variables we just have give
command --> aws eks update-kubeconfig --region ap-south-1 --name ToDo-App

Step-12 Setup your ENV variable's into our CircleCi

Go to project settings
There we have ENV-VAR
Add there docker-username, Docker-pswd, Github personal token

Step-13 Check with argocd resources are created

now run following commands one by one
kubectl create ns argocd

kubectl apply -n argocd -f
https://raw.githubusercontent.com/argoproj/argocd/stable/manifests/install.sh

kubectl port-forward svc/argocd-server 8080:443 -n argocd
