1. 针对应用程序，使用以下Dockerfile来创建自定义运行时的映像：

FROM google/cloud-sdk:277.0.0-alpine
RUN apk --no-cache add openjdk8
ENV APP_HOME /app
WORKDIR $APP_HOME
COPY . .
CMD ["/usr/bin/java", "-jar", "/app/myapp.jar"]

注意：替换“myapp.jar”为应用程序的实际名称。

2. 确保已经安装了gcloud SDK，并且在启动Ansible之前配置好SDK。

---
- name: Ensure gcloud is installed
  shell: |
    curl https://sdk.cloud.google.com | bash
    exec -l $SHELL
    gcloud --version
  changed_when: false

- name: Authenticate to GCP
  shell: gcloud auth activate-service-account --key-file "{{ service_account_key_path }}"
  changed_when: false

- name: Deploy to App Engine
  shell: gcloud app deploy app.yaml --version="{{ app_version }}" --project="{{ project_id }}"

3. 之后，您需要为自定义运行时配置“app.yaml”文件，并指定您的Docker映像。

runtime: custom
env: flex
service: myapp
handlers:
  - url: /.*
    script: null
  # the app listens on port 8080 inside the container
  - url: ".*"
    script: auto
    secure: always
    redirect_http_response_code: 301
    # specify your Docker image here
    # the latest tag is used by default
    # you can also specify a different tag, e.g. my-image:v1
    # use the command 'docker push gcr.io/PROJECT_ID/your-image:your-tag' to push the image to GCR
    # substitute PROJECT_ID with your actual project ID
    # and your-image:your-tag with the actual image name and tag
    # to build and push the Docker image, use the command 'docker build -t gcr.io/PROJECT_ID/your-image:your
