How to run the springboot project in docker

1. Click Terminal below in IDEA and enter mvn clean install

When the following figure appears, it indicates success (the premise is that Maven must be installed locally and the Maven environment variables must be configured)

The packaged jar is in the target directory

2. Then create a new Dockerfile file with the following content

3. Build the image: Place the Dockerfile and project jar package in the same directory on the server, and then enter the directory

Enter: docker build -t app . (note there is a dot at the end, app is the custom image name) to build the image

Check if the image exists: docker images

4. Run the image just created: docker run -d -p 8888:8081 --name app app

illustrate:

-d runs the container in the background;

--name specifies the container name;

-p specifies the port where the service runs (the first one is the host mapping port number, and the second one is the project port number)

Open the browser IP:8888 to view

5. View container logs: docker logs -f -t --tail 500 app
