This repository showcases the improvements I made to the original project DevOps-The-Hard-Way-Azure. The purpose of these enhancements is to dive deeper into various technologies and concepts such as Argo CD, Kubernetes, GitHub Actions, Terraform, and Azure. The following steps outline the changes and additions I made to the project:(https://github.com/thomast1906/DevOps-The-Hard-Way-Azure).

1. Create a resource group, a storage account and a storage blob to store remote terraform state.

./infrastructure/scripts/create-terraform-storage.sh

2. Create an azure AD group for aks admins and add current logged in user as a member.

./infrastructure/scripts/create-azure-ad-group.sh

3. Create a resource group for ACR and ACR using terraform.

cd infrastructure/terraform-workspace/ACR

terraform init

terraform plan

terraform apply

4. Create a VNET and 2 subnets

cd infrastructure/terraform-workspace/VNET

terraform init

terraform plan

terraform apply

5. Create a Log Analytics workspace and solution

cd infrastructure/terraform-workspace/Log-Analytics

terraform init

terraform plan

terraform apply

5. Create AKS cluster and assign roles to kubelet (acr-pull and scale-up;scale-down)

cd infrastructure/terraform-workspace/AKS

terraform init

terraform plan

terraform apply

6. Dockerize uber app and push to ACR as a starting point

docker build -t uberapp .

docker tag uberapp {name-of-acr}.azurecr.io/uberapp:v1

az acr login --name {name-of-acr}

docker push {name-of-acr}.azurecr.io/uberapp:v1

7. Install ARGOCD and apply CRD for ARGOCD to manage uber-app

az aks get-credentials --resource-group infrastructure-rg --name infrastructureaks

kubectl create namespace argocd

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

7.1 ARGOCD needs to be exposed, for this example I modified the service from a ClusterIP to a LoadBalancer

kubectl edit svc argocd-server -n argocd

Get password of ARGOCD

{bash}
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d; echo (get pw)

{powershell}
[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String((kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}")))

Apply helm template of a CRD argo app from my other repo, which points to the helm template of uber-app (separate repo)

kubectl apply -f https://github.com/celtic01/argocd-uberapp/blob/main/helm/templates/uber-app.yaml

8. Uber app is stored in a separate repository, I have created the CI in github actions for it in order to push the image to ACR and update the app helm template which was in the same repo

https://github.com/celtic01/uber-app-clone/blob/main/.github/workflows/build-push.yml

These improvements have provided me with valuable hands-on experience in using Argo CD, Kubernetes, GitHub Actions, Terraform, and Azure. By integrating Argo CD and GitHub Actions into the existing Uber app Python clone, I was able to enhance the project's functionality and gain deeper insights into these technologies.
