Overveiw of the Program

This program is very simple, it connects to a MySQL database based on the following env vars:

• MYSQL_HOST
• MYSQL_USER
• MYSQL_PASS
• MYSQL_PORT

And exposes itself on port 9090:

• On /healthcheck it returns an OK message,
• On GET it returns all recorded rows.
• On POST it creates a new row.
• On PATCH it updates the creation date of the row with the same ID as the one specified in query parameter id# instaBug

what is the purpose of the task:

• Fix bugs in code
• Dockerizing App
• Compose the API image & Mysql
• CI/CD Jenkins Pipeline
• Kubernetes + packaging it using helm & kustomization file
• ArgoCD for GitOps
• Horizontal Pod Autoscaler

Notes:

• The .env file is used to store the required environment variables for the application. Ensure that you provide the correct values for MYSQL_HOST, MYSQL_USER, MYSQL_PASS, and MYSQL_PORT.
• it shoud be in instabug-intern-challenge/ dir.

Run Api Locally Using Golang and mysql-server:

git clone https://github.com/Elheity/instaBug.git
cd instabug
go build -o main .
./main

Fix bug in the code

Build Docker Image:

sudo docker build -t internship .

• Dockerfile Built in the way that make it as lightweight as possible with all layers of security.

Run API And It's Database Using Docker-Compose:

docker-compose up 

• In Docker-compose The Api Will Start Only After Mysql DB Be Healthy, So i add Healthcheck for my compose file

Screenshot From Running API Localy With Docker-compose:

Minikube Cluster Setup:

# Start the Minikube cluster using the Docker driver by running the command: 

 minikube start --driver docker

# Verify the status of the Minikube cluster using the command:

 minikube status

Ensure that the control plane components, including the host, kubelet, apiserver, and kubeconfig, are running and properly configured.

Install API Using Kubectl:

kubectl apply -f kubernetes//app-deployment.yaml 
kubectl apply -f kubernetes//app-service.yaml 
kubectl apply -f kubernetes//db-deployment.yaml 
kubectl apply -f kubernetes//db-service.yaml 
kubectl apply -f kubernetes//app-config.yaml 

Install API Using Helm:

helm install mywebapp-release helminsta/ --namespace default --set fullnameOverride=mywebapp-release --set releaseNamespace=default

ArgoCD SETUP:

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Enable Sync Between Github & K8s ArgoCD Cluster By:

Install API By Using Helm Charts Command OR By Run Application.yaml K8s File And It Will Sync Automatically. and it also point to helm package.

kubectl apply -f helminsta/templates/application.yaml
