After running bash script (.sh) file, the process does not come back to the docker compose entry point

I have some spring boot microservices. I want to run them using docker compose. To be sure that services run in order, I have used a .sh file to run one of them before others because other microservices depend on it. The bash script file runs very well but it stops the caller container. I searched on Internet and realized that some commands must be added at the end of the bash script file: /cnb/process/web or ./cnb/lifecycle/launcher in order to continue the process. But this message is shown: /cnb/process/web: No such file or directory.

Spring boot version: 3.2.2

Docker compose: 3.8

.sh file:

#!/bin/bash
# check-config-server-started.sh

apt-get update -y
yes | apt-get install curl

curlResult=$(curl -s -o -I -w "%{http_code}" http://cloud-config-server:8888/actuator/health)

echo "result status code:" "$curlResult"

while [[ ! $curlResult == "200" ]]; do
  >&2 echo "Config server is not up yet!"
  sleep 2
  curlResult=$(curl -s -o -I -w "%{http_code}" http://cloud-config-server:8888/actuator/health)
done
/cnb/process/web
#./cnb/lifecycle/launcher

I have faced with the same problem. I mean keeping containers running after executing .sh files by adding /cnb/process/web to the .sh file. It seems the problem originates from the way you create your docker image. In the docker compose file instead of using

build: dockerfile: ./Dockerfile

I create docker images using spring boot pom.xml by adding these codes:

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>${spring-boot.version}</version>
                <configuration>
                    <image>
                        <name>${project.groupId}/my.service:${project.version}</name>
                    </image>
                </configuration>
                <executions>
                    <execution>
                        <phase>install</phase>
                        <goals>
                            <goal>build-image</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

then mvn clean install to create an image.

after that you can refer to the image in the docker compose:

image: your-image-name

instead of

build:
  dockerfile: ./Dockerfile
