I would like to post my application made in spring boot using docker for the first time. However, a problem arose while posting it.

So, the image I uploaded to the conter does not display.

Here are the steps I took, and I'll add right away that I used gradle.

1. I downloaded the Docker plugin to IntelliJ
2. I created a Dockerfile in which I put:

3. In the terminal, I typed the following commands to build the project:

4. Then I typed (to create an image and display it):

5. And here is where the problem arises, I entered the following commands:

   (I want to run on port 8081 because my app listens on port 8080. I don't know if it matters but that's how I did it)

I display the list using command: docker container ps

After typing the docker container ps command, no created container is displayed to me, I get an empty list, and after typing the first command I get logs (a string of characters and numbers, which probably indicates the success of the operation) but I do not know why the container is not created.

I have no idea what I'm doing wrong that it's not working, where I'm making a mistake. Is there something else I should do? In general, the spring boot application at this time should be running? What does it look like, I read some tutorials but unfortunately nothing helped, and I was doing the same way as them

You can also create a Docker image with Maven plugin by defining in pom.xml and run 'mvn install':

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <image>
                        <name>
                            ${project.groupId}/twitter.to.kafka.service:${project.version}
                        </name>
                    </image>
                </configuration>
                <executions>
                    <execution>
                        <!-- Create Docker image during mvn install -->
                        <phase>install</phase>
                        <goals>
                            <!-- Spring Boot use the Layered approach : to prevent creating a single fat jar, and use caching during image update -->
                            <goal>
                                build-image
                            </goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

Can you try this instead of manually creating a Dockerfile ?

try to run:

docker run -p 8081:8081 springreadyapp

i add a link to my repo which explain about that, in maven docker with spring
