You can download Maven and install it according the installation guide steps here. This is the information of Maven version used:
$ mvn --version
Apache Maven 3.8.3 (ff8e977a158738155dc465c6a97ffaf31982d739)
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
To run the application execute the command at root of the repository folder:
$ mvn spring-boot:run
In the same way you can use the Maven Wrapper plugin on the repository source code:
$ ./mvnw spring-boot:run
As we analyze in this articule Docker multi-stage build for Spring Boot application this is the best solution that I found for this image building. Please let me know of any improvements!!!!!
Dockerfile:
FROM openjdk:8-jdk-alpine as build
COPY . /usr/app
WORKDIR /usr/app
RUN chmod +x mvnw && ./mvnw clean package
FROM openjdk:8-jre-alpine
COPY --from=build /usr/app/target/*.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","app.jar"]
We can build the application image with the command:
$ docker build -t josephrodriguez/learning-spring-boot -f ./Dockerfile .
Also you can download and run the Docker image from Docker Hub:
$ docker run -p 8080:8080 josephrodriguez/learning-spring-boot
docker-compose.yml:
version: "3.8"
services:
app:
build:
context: .
dockerfile: Dockerfile
ports:
- "8080:8080"
Execute the command to run the application:
docker-compose up --build
In any case you should see an output very similar to this:
