spring-boot-starter-parent- Parent pom providing dependency and plugin management for applications built with Maven.spring-boot-starter-web- Starter for building web, including RESTful, applications using Spring MVC. Uses Tomcat as the default embedded container.spring-boot-starter-test- Starter for testing Spring Boot applications with libraries including JUnit Jupiter, Hamcrest and Mockito.spring-boot-autoconfigure- Automatically configure a Spring application based on the dependencies that are present on the classpath.spring-boot-maven-plugin- Provides Spring Boot support in Apache Maven.
Enabled by default, or by providing the greeting.service.type=default config parameter.
Returns the following message "<greet>, <name>!" where name is a request parameter, and greet is a configurable
value. The greet is configurable by providing one of the following values
for greeting.service.default.greet=<value>:
HELLO(set for prod profile)HEY(set for test profile)HI(set for dev profile)
in the resources/application.properties file.
The previous values will generate the following messages in order:
- Hello,
<name>! - Hey,
<name>! - Hi,
<name>!
Enabled by providing the greeting.service.type=daytime config parameter. Daytime service greets with a
message: "<greet>, <name>!"
where greet is dependent on the time of the day, and name is the request parameter.
One of the following three profiles can be used by providing the spring.profiles.active=<profile> parameter:
dev(this is the default profile used if no other is specified)testprod
To run the app locally from IntelliJ simply run the org.drivemybox.interview.InterviewApplication class with
configuration parameters (environment variables in IntelliJ run configuration) of your choice.
First ensure you have maven installed with the command mvn -v. From the repository root run mvn install build the
project into the target directory.
If everything went fine, a .jar should be in the target directory. You can run that .jar file with the java -jar
command. You can add configuration properties as
follows java -jar target/drivemybox-interview.jar --greeting.service.default.greet=<value>
Use the mvn test command to run all integration and unit tests.
Ensure docker is installed by running the
docker -v command. First build a docker image with a costum name drivemybox-interview by opening a CMD in the
repository root and running the sudo docker build -t drivemybox-interview . command. If the build finished
successfully you should be able to run the docker application with the following command
sudo docker run -p 8080:8080 -d drivemybox-interview. Note that 8080:8080 in the previous command can be changed
to <port>:8080 where port can be any available port of your choice where you want the application to listen, while
the second 8080 is the configured Spring Boot application port. Ensure that the application is running in docker with
the following command sudo docker ps. When you want to stop the application from running use sudo docker stop <id>
where id is the one matching your application listed in the sudo docker ps
output table. You can choose a profile for the docker application by adding -e "SPRING_PROFILES_ACTIVE=<profile>"
to the docker run command, where profile is one of dev, test, prod.
Use the command mvn compile dependency:copy-dependencies -DincludeScope=runtime -f pom.xml in order to copy the aws lambda required
runtime files. Then build the docker image and deploy it to ECR. Create a new Lambda from the uploaded image. Create a new API gateway as a
trigger for the lambda. The resource points to the endpoint, and the method MUST BE A PROXY METHOD for lambda. Otherwise, the AWS
dependencies will complain about the message format since it only works with AWS Proxy Messages. It's also important that dependencies are
minimal, in order to keep the startup time under 10 seconds, because 10 seconds is the max duration of the INIT phase of AWS Lambda. If it
takes more than 10 seconds the lambda will respond with an error.
