Dockerizing a Spring Boot application is a great way to make it portable and easy to deploy. Here are the steps involved: Dockerizing a Spring Boot Application

1. Create a Dockerfile. The Dockerfile is a text file that tells Docker how to build your image.
2. Build the image. Once you have a Dockerfile, you can build the image using the docker build command.
3. Run the image. Once you have built the image, you can run it using the docker run command.

Here is an example of a Dockerfile for a Spring Boot application:

FROM openjdk:8-jdk-alpine

RUN apk add --no-cache curl

WORKDIR /app

COPY target/my-app.jar .

EXPOSE 8080

ENTRYPOINT ["java", "-jar", "my-app.jar"]

This Dockerfile tells Docker to use the openjdk:8-jdk-alpine image as the base image. It then installs the curl package, copies the my-app.jar file into the /app directory, exposes port 8080, and sets the ENTRYPOINT to java -jar my-app.jar.

To build the image, you can use the following command:

docker build -t my-app .

This will create an image named my-app. To run the image, you can use the following command:

docker run -p 8080:8080 my-app

This will start a container running the my-app image and map port 8080 on the host machine to port 8080 on the container. You can then access the application at http://localhost:8080.

Here are some additional tips for dockerizing a Spring Boot application:

• Use a base image that is as small as possible. This will reduce the size of your image and make it faster to deploy.
• Use a multi-stage build to build your image. This will help you to reduce the size of your image by only including the files that are necessary for your application to run.
• Use environment variables to configure your application. This will make it easier to change the configuration of your application without having to rebuild the image.

Dockerizing a Spring Boot application can be a great way to make your application more portable and easy to deploy. By following these tips, you can create a Docker image that is small, efficient, and easy to use.

Dockerizing a Spring Boot Application

make Dockerfile in the root folder and add the following line

FROM openjdk:8-jdk-alpine
ADD /build/libs/asset-management-service.jar asset-management-service.jar
ENTRYPOINT ["java","-jar","/asset-management-service.jar"]
EXPOSE 9195

save file with the name of Dockerfile.
Type the following command is used to remove exiting container 
 sh 'sudo docker rm $(sudo docker stop $(sudo docker ps -a | grep "work-order-service" | cut -d " " -f 1))'
sh 'sudo docker build -t work-order-service .'
sh 'sudo docker run -d work-order-service'
sh 'sudo docker ps -a | grep work-order-service'
