Recently Microsoft announced Azure Spring Cloud project. In cooperation with Pivotal, they created a platform that makes a microservices application using Spring Cloud deployment very easy. It has been released today, so let’s try it!
Let’s start with setting up Azure CLI:
Login and setup subscription:
az login az account list -o table az account set --subscription
Add Azure Spring Cloud CLI extension:
az extension add --name spring-cloud
Create a resource group, provision an instance of Azure Spring Cloud and set them as defaults:
az group create --location westeurope --name spring-cloud-fun-group az spring-cloud create -n spring-cloud-fun -g spring-cloud-fun-group az configure --defaults group=spring-cloud-fun-group az configure --defaults spring-cloud=spring-cloud-fun
Config server setup
For deployment, we are going to use Piggymetrics sample project from Azure Samples (it’s a fork of the original piggymetrics project).
First, we need to update config-server:
az spring-cloud config-server git set -n spring-cloud-fun --uri https://github.com/Azure-Samples/piggymetrics --label config
That’s it, we have configuration server set up. The command above made config server use config branch of the Piggybank git repository.
The branch contains only config YAML files for all the services (account-service.yml, application.yml, auth-service.yml, gateway.yml).
When setting up properties for services in gonfig server be aware that Azure injects following properties automatically and should not be used manually in config files:
eureka.client.service-url.defaultZone eureka.client.tls.keystore server.port spring.cloud.config.tls.keystore spring.application.name
Build the project and deploy
Checkout project and build:
git clone https://github.com/Azure-Samples/piggymetrics cd PiggyMetrics mvn clean package -DskipTests
az spring-cloud app create --name gateway az spring-cloud app create --name auth-service az spring-cloud app create --name account-service
az spring-cloud app deploy -n gateway --jar-path ./gateway/target/gateway.jar az spring-cloud app deploy -n account-service --jar-path ./account-service/target/account-service.jar az spring-cloud app deploy -n auth-service --jar-path ./auth-service/target/auth-service.jar
Make the gateway public and get its public URL:
az spring-cloud app update -n gateway --is-public true az spring-cloud app show --name gateway | grep url
In response, you should get URL like https://spring-cloud-fun-gateway.azuremicroservices.io/
If you open it, you should see the Piggy Metrics login page:
That’s it, deployment of three Spring Cloud microservices takes about
20 minutes, where most of the time is consumed by environment provisioning. Config, discovery, logging, monitoring, alerting and distributed tracing services are provided out of the box so a lot of infrastructure does not have to be set up manually.
Azure Spring Cloud was released officially today. It looks promising and is definitely worth looking at, especially when you want to quick start with Spring Cloud.
