Creating and uploading a Quarkus project to AWS Lambda
Published Mar 27, 2020
I just wanted to play with Quarkus and AWS Lambda. I did a little proof of concept in one evening. There’s a lot of things to improve of course but it shows that Java has evolved a lot and can start really fast.
This project uses Quarkus, the Supersonic Subatomic Java Framework. If you want to learn more about Quarkus, please visit its website here.
Create the Java project
Check the last version of the plugin
Check the latest version of the quarkus-maven-plugin on Maven Central - quarkus-maven-plugin
Create the project using the plugin
mvn io.quarkus:quarkus-maven-plugin:1.3.0.Final:create \
-DprojectGroupId=com.github.thibaudledent \
-DprojectArtifactId=quarkus-poc \
-DclassName="com.github.thibaudledent.quarkus.poc.HelloResource" \
-Dpath="/quizz"
Compile in dev mode
mvn compile quarkus:dev
Try it out with curl
curl -X GET "localhost:8080/quizz"
Run a Containerized Native Image
In order to build a native image, you don’t need to have GraalVM configured locally, Quarkus can use a dedicated containerized version of GraalVM for that:
Package the image
mvn package -Pnative -Dquarkus.native.container-build=true
Build the image
docker build -f src/main/docker/Dockerfile.native -t thibaudledent/quarkus-poc .
A Docker image is created, you can check its size:
docker images -a | head
It outputs:
REPOSITORY TAG IMAGE ID CREATED SIZE
thibaudledent/quarkus-poc latest d0d0209d1325 13 seconds ago 155MB
Run the image
docker run thibaudledent/quarkus-poc
Starting time is fast. You can check the startup time with:
time docker run thibaudledent/quarkus-poc

Running a Standalone Jar
mvn package
java -jar target/quarkus-poc-1.0-SNAPSHOT-runner.jar
Deploying the Standalone Jar on AWS Lambda
Note: This step can be improved by using Quarkus - Amazon Lambda instead.
Create a function with Java runtime
Upload the jar
Upload the jar from target/quarkus-poc-1.0-SNAPSHOT-runner.jar created with mvn package:
Use the following as handler:
com.github.thibaudledent.quarkus.poc.HelloResource::hello
Test it
