Step-01: Introduction¶

What are the problems with MySQL Pod & Azure Disks?
How we are going to solve them using Azure MySQL Database?

Azure Kubernetes Service with Azure DevOps and Terraform¶

Step-02: Create Azure Database for MySQL servers¶

Go to Service Azure Database for MySQL servers
Click on Add
Basics
Project details
Subscription: Free Trial
Resource Group: aks-rg1
Server Details
Server name: akswebappdb (This name is based on availability - in your case it might be something else)
Data source: none
Location: (US) East US
Version: 5.7 (default)
Compute + Storage
- Pricing Tier: Basic
- VCore: 1
- Storage: 5GB
- Storage Auto Growth: Yes
- Backup Retention: 7 days
- Locally Redundant: Yes
Administrative Account
Admin username: dbadmin
Password: Redhat1449
Confirm password: Redhat1449
Review + Create
It will take close to 15 minutes to create the database.

Step-03: Update Security Settings for Database¶

Go to Azure Database for MySQL Servers -> akswebappdb
Settings -> Connection Security
Very Important: Enable Allow Access to Azure Services
Update Firewall rules to allow from local desktop (Add current client IP Address)
SSL Settings: Disabled
Click on Save
It will take close to 15 minutes for changes to take place.

# Template
mysql --host=mydemoserver.mysql.database.azure.com --user=myadmin@mydemoserver -p

# 
mysql --host=akswebappdb.mysql.database.azure.com --user=dbadmin@akswebappdb -p

Step-04: Create Kubernetes externalName service Manifest and Deploy¶

Create mysql externalName Service

01-MySQL-externalName-Service.yml

apiVersion: v1
kind: Service
metadata:
  name: mysql
spec:
  type: ExternalName
  externalName: akswebappdb.mysql.database.azure.com

Deploy Manifest

kubectl apply -f kube-manifests/01-MySQL-externalName-Service.yml

Step-04: Connect to RDS Database using kubectl and create usermgmt schema/db¶

# Template
kubectl run -it --rm --image=mysql:5.7.22 --restart=Never mysql-client -- mysql -h <AZURE-MYSQ-DB-HOSTNAME> -u <USER_NAME> -p<PASSWORD>

# Replace Host Name of Azure MySQL Database and Username and Password
kubectl run -it --rm --image=mysql:5.7.22 --restart=Never mysql-client -- mysql -h akswebappdb.mysql.database.azure.com -u dbadmin@akswebappdb -pRedhat1449

mysql> show schemas;
mysql> create database webappdb;
mysql> show schemas;
mysql> exit

Step-05: In User Management WebApp deployment file change username from `root` to `dbadmin@akswebappdb`¶

02-UserMgmtWebApp-Deployment.yml

# Change From
          - name: DB_USERNAME
            value: "root"
          - name: DB_PASSWORD
            value: "dbpassword11"               

# Change To dbadmin@<YOUR-Azure-MYSQL-DB-NAME>
            - name: DB_USERNAME
              value: "dbadmin@akswebappdb"            
            - name: DB_PASSWORD
              value: "Redhat1449"

Step-06: Deploy User Management WebApp and Test¶

# Deploy all Manifests
kubectl apply -f kube-manifests/

# List Pods
kubectl get pods

# Stream pod logs to verify DB Connection is successful from SpringBoot Application
kubectl logs -f <pod-name>

Step-07: Access Application¶

# Get Public IP
kubectl get svc

# Access Application
http://<External-IP-from-get-service-output>
Username: admin101
Password: password101

Step-08: Clean Up¶

# Delete all Objects created
kubectl delete -f kube-manifests/

# Verify current Kubernetes Objects
kubectl get all

# Delete Azure MySQL Database
