COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
RUN javac
CMD ["java", "Main"]
$ docker build -t my-java-app .
$ docker run -it --rm --name my-running-app my-java-app

Amazon Corretto#

Corretto is a no-cost, production-ready distribution of the Open Java Development Kit (OpenJDK).

docker pull amazoncorretto:8
docker pull amazoncorretto:11
docker run --rm amazoncorretto:8 java -version

vi Dockerfile

FROM amazoncorretto:8
# RUN echo $' \
RUN echo ' \
public class Hello { \
public static void main(String[] args) { \
System.out.println("Welcome to Amazon Corretto!"); \
} \
}' >
RUN javac
CMD ["java", "Hello"]
docker build -t hello-app .
docker run --rm hello-app
docker run --rm -it hello-app sh

How is Corretto different from OpenJDK?#

Corretto is a distribution of Open JDK with patches included by Amazon that are not yet integrated in the corresponding OpenJDK update projects. We focus on patches that improve performance or stability in OpenJDK, chosen based on Amazon’s observations running large services.

What is included in Corretto’s long-term support?#

Amazon will provide security updates for Corretto 8 until at least June 2023. Updates are planned to be released quarterly. Corretto 11, corresponding to OpenJDK 11, will be available during the first half of 2019. Amazon will support Corretto 11 with quarterly updates until at least August 2024.
