当出现消息“在http://0.0.0.0:5000/上运行按CTRL + C退出”时，如何继续我的代码船构建

如何解决当出现消息“在http://0.0.0.0:5000/上运行按CTRL + C退出”时，如何继续我的代码船构建

使用代码构建我的flask应用程序。执行codeship-steps.yml并显示消息时，构建卡住了

(service: app) (step: build)  * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)

APP代码：

应用程序代码位于包含三个文件的名为app的文件夹中

__main__.py templates web.py

index.html位于templates

来自web.py的代码

app = Flask(__name__)

@app.route("/")
def home():
    return render_template("index.html")

来自__main__.py的代码

if __name__ == "__main__":
    app.run(host='0.0.0.0')

index.html

的输出

<h1>Hello</h1>

codeship-services.yml文件步骤

app:
  build:
    image: id/pythonapp
    dockerfile: Dockerfile
    args:
      build_env: production
  cached: true

codeship-steps.yml文件步骤：

- name: build
  service: app
  command: build-command
- name: test
  service: app
  tag: master
  command: test-command
- name: publish
  service: app
  type: push
  image_name: id/repo
  registry: https://index.docker.io/v1/
  encrypted_dockercfg_path: dockercfg.encrypted

Dockerfile内容：

FROM python:3.8-alpine

workdir /task/devops
ENV PATH="/task/devops:${PATH}"

copY . .
RUN mv secret.txt /var/secret.txt
RUN pip install -r requirements.txt

CMD [ "task-devops" ]     ## task-devops is a file

task-devops的内容：

#! /bin/sh

function help_menu {
    cat README.md
}

function tasks_display {
    cat TASKS.md
}

function unit_tests {
    py.test tests/*
}

function serve {
    python app/
}

if [[ $# -eq 0 ]] ; then
    help_menu
    exit 0
fi

case "$1" in
    help) help_menu & ;;
    test) unit_tests & ;;
    serve) serve & ;;
    tasks) tasks_display & ;;
    x) cat /var/secret.txt & ;;
    *) help_menu &;;
esac

child=$!
wait "$child"
#2> /dev/null

从日志中注意到，docker Image创建成功。但是我的应用程序卡住了。如何继续进行构建？
