This repository is part of the presentation "TFTEC AO VIVO EM SÃO PAULO 2024". For more information about the event, please visit here.

Pre-requisites

1. Azure Cloud Subscription
2. Azure Devops
3. Course Github Repositories
4. Basic infrastructure created in the previous lab: Azure Kubernetes Service with Azure DevOps and Terraform
5. Azure CLI
6. Kubernetes kubectl tool

1. Fork Course Github Repositories

• TFTEC Microservice app with Azure DevOps

2. Create the Microservice repository

Create a new repository in the training project with the suggested name: tftec-app.

3. Upload the base repository to Azure Repo.

4. In Azure Pipelines, configure the set of variables.

Go to Pipeline > Library and add Variable group:

Variable group name: tftec-app-vars

Variable	Value
dockerfilePath	docker/Dockerfile
HelmRepoName	helm-chart/ao-vivo-sp-24
imageRepository	image/ao-vivo-sp-24/tftec-app
tag	$(Build.BuildId)

5. Configure Service Connection

Click Project settings > Pipelines > Service connections > New service connection.

Create the Kubernetes service connection:

Select Kubernetes > next > select the subscription.

For Service connection name: tftec-kubernetes

Check Grant access permission to all pipelines and save.

Crie a service connection do Azure Container Registry:

Selecione Docker Registry > next > Azure Container Registry.

Authentication Type: Service Principal > selecione a assinatura.

Service connection name: tftec-registry

Check Grant access permission to all pipelines and save.

6. Make the necessary adjustments to the build and deploy pipelines

Build pipeline:

Access the yaml file and make changes according to your environment in the settings marked with MODIFICAR.

Build pipeline:

Access the yaml file and make changes according to your environment in the settings marked with MODIFICAR.

6. Create the microservice build and deploy pipelines

Build pipeline:

Pipelines > New pipeline > Azure Repos Git > <repo_name> > Existing Azure Pipelines YAML file > Branch main > path /cicd/stages/stages-build.yml > continue > rename to tftec-app-build > save.

Deploy pipeline:

Pipelines > New pipeline > Azure Repos Git > <repo_name> > Existing Azure Pipelines YAML file > Branch main > path /cicd/stages/stages-deploy.yml > continue > rename to tftec-app-deploy > save.

7. Building and deploying the microservice

Run the tftec-app-build build pipeline after success, collect build release information from Azure Container Registry, image and chart.

With the information in hand, edit the build information in the stages-deploy.yml pipeline, save it, and monitor the pipeline execution. If the pipeline is not triggered automatically, go to pipelines and manually run the pipeline tftec-app-deploy.

Example:

• imageTag: 'latest'
• chartVersion: '657'

9. Cheque a implatanção do microservico no cluster AKS

Access the AKS cluster via the Azure portal, click connect, select Azure CLI and follow the commands to log in, set up the subscription and download the credentials.

Test connectivity and list the nodes in your cluster:

kubectl get nodes

Confirm that the microservice objects have been created and are running perfectly.

kubectl get deployments

kubectl get services

kubectl get secrets

kubectl get pods
