The command line to run this container had three arguments: We see the container is up and running! You have a Spring Boot application running on Docker. Spring-boot-app:latest Up 2 minutes 0.0.0.0:8080->8080/tcp eloquent_varahamДocker ps displays the running containers on the host machine. Take a look at whatвЂ™s running: $ docker ps Point a web browser at and you see the employee record. You will also see openjdk, which docker created as part of the build process. Your new image is there, named spring-boot-app as specified in the build command. Openjdk 8-jre-alpine c529fb7782f9 3 days ago 82MBДocker image ls lists the images on our system. IвЂ™ll cover the contents of the file and what happens during the build after this initial image is running.ДЇinally, you can take a look at the build results: $ docker image ls Successfully tagged spring-boot-app:latest Removing intermediate container 04bf7e97079a Step 2/3 : COPY target/spring-boot-app-0.0.1-SNAPSHOT.war /app.war Status: Downloaded newer image for openjdk:8-jre-alpine Then, build the image: $ docker build -t spring-boot-app:latest. Make sure your pom.xml has this block in the plugins section: This copies the jar into the docker directory as part of the package build target. Next, add the output directory property to the spring-boot-maven-plugin. You canвЂ™t use relative paths in Dockerfiles, so youвЂ™ll need to modify our pom.xml to place the war file in the target directory. Place this file in a new folder at the top of your project named docker. ItвЂ™s a best practice to build images in a вЂњcleanвЂќ directory, as docker buildвЂ™s default behavior is to copy the working directory to the image. WeвЂ™ll take a closer look at these commands below. You create images with a Dockerfile, which lists the components and commands that make up the package.ДЇirst, create the file : # Alpine Linux with OpenJDK JREД¬OPY spring-boot-app-0.0.1-SNAPSHOT.war /app.warД¬MD Дockerfiles are a list of commands that docker performs to build an image. Build and run a Docker application Building an Image LetвЂ™s get right to work running this in docker. It serves a single page at /springbootapp/employees: You can run the application with this command line: java =default -jar target/spring-boot-ops.war

ItвЂ™s a small web application that manages employee records. To keep the tutorial focused on Docker, weвЂ™ll use an existing project, which is explained in this Spring tutorial. Once the image was completely downloaded, it ran hello-world in a container. Since it wasnвЂ™t present, it went to Docker Hub and downloaded the latest image. Then it runs the container, which displays a message telling us everythingвЂ™s working fine, and then it spells out the process it took to run the image.Дocker looked for a local copy of the hello-world image. Since it is not there it downloads it from Docker Hub.

Your version may be different, depending on your platform.Дocker run hello-world does what it sounds likeВ вЂ“ it runs an image named hello-world.ДЇirst, it looks for this image on the local system. The first command checks dockerвЂ™s version. This message shows that your installation appears to be working correctly. Status: Downloaded newer image for hello-world:latest Next, verify the installation with the following two commands: $ docker -version

Docker setup and installation Install DockerДЇirst, start by installing the Docker desktop tools found here. In this tutorial, weвЂ™ll package a Spring Boot application, run it, and look at the different commands for managing images and containers. Containers are also an excellent first step toward moving toward a flexible and cost-effective cloud architecture. Running a service in a container augments development with a common target platform for development, testing, and deployment. Java microservices are a good target for Docker. Images, the packages Docker uses for applications, are truly cross-platform. It can run containers on any system that supports the platform: a developerвЂ™s laptop, systems on вЂњon-prem,вЂќ or in the cloud without modification. Intro to managing and running a containerized Java Spring Boot applicationДocker is a platform for packaging, deploying, and running applications in containers.
