Deployment Guide: Spring Boot to Azure Container Apps

Phase 1: Create Container Apps Environment

Bash:

#!/bin/bash
set -euo pipefail
az group create --name spring-rg --location eastus
az monitor log-analytics workspace create --resource-group spring-rg --workspace-name spring-logs --location eastus
LOG_ID=$(az monitor log-analytics workspace show --resource-group spring-rg --workspace-name spring-logs --query customerId -o tsv)
LOG_KEY=$(az monitor log-analytics workspace get-shared-keys --resource-group spring-rg --workspace-name spring-logs --query primarySharedKey -o tsv)
az containerapp env create --name spring-env --resource-group spring-rg --location eastus --logs-workspace-id "$LOG_ID" --logs-workspace-key "$LOG_KEY"

PowerShell:

az group create --name spring-rg --location eastus
az monitor log-analytics workspace create --resource-group spring-rg --workspace-name spring-logs --location eastus
$LOG_ID = az monitor log-analytics workspace show --resource-group spring-rg --workspace-name spring-logs --query customerId -o tsv
$LOG_KEY = az monitor log-analytics workspace get-shared-keys --resource-group spring-rg --workspace-name spring-logs --query primarySharedKey -o tsv
az containerapp env create --name spring-env --resource-group spring-rg --location eastus --logs-workspace-id "$LOG_ID" --logs-workspace-key "$LOG_KEY"

Phase 2: Configure Logging

Update application.properties:

logging.pattern.console=%d{yyyy-MM-dd HH:mm:ss} - %msg%n

Configure diagnostic settings: Azure Monitor Log Analytics (recommended), Event Hubs, or third-party solutions.

Phase 3: Containerize Application

Dockerfile:

FROM mcr.microsoft.com/openjdk/jdk:21-ubuntu
WORKDIR /app
COPY target/*.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "app.jar"]

Build and push (Bash):

ACR_NAME="${ACR_NAME:-<acr>}"
az acr create --name "$ACR_NAME" --resource-group spring-rg --sku Basic --location eastus
az acr login --name "$ACR_NAME"
docker build -t "${ACR_NAME}.azurecr.io/spring-app:v1.0" .
docker push "${ACR_NAME}.azurecr.io/spring-app:v1.0"

Build and push (PowerShell):

$ACR_NAME = if ($env:ACR_NAME) { $env:ACR_NAME } else { "<acr>" }
az acr create --name "$ACR_NAME" --resource-group spring-rg --sku Basic --location eastus
az acr login --name "$ACR_NAME"
docker build -t "${ACR_NAME}.azurecr.io/spring-app:v1.0" .
docker push "${ACR_NAME}.azurecr.io/spring-app:v1.0"

Phase 4: Configure Storage (if needed)

Azure Files for persistent storage (Bash):
