我正在尝试将我的 Docker 映像从 Docker Hub 部署到 Rancher。当我这样做时，我只得到更新状态，然后过了一段时间，我得到了部署超时。我是 Rancher 的新手，正在尝试浏览文档但无法正确理解。谁能帮助我做到这一点？

我已经尝试拉取图像，一段时间后它显示“部署没有最低可用性”。

下面是我的 .gitlab-ci.yml 文件配置：

stages:
  - build
  - publish

.build: &build_template
  stage: build
  image: microsoft/dotnet:2.2-sdk-alpine
  cache:
    key: "$CI_PROJECT_NAMESPACE-$CI_PROJECT_NAME"
    paths:
      - .nuget/
  script:
    - dotnet restore -s https://api.nuget.org/v3/index.json --packages ./.nuget/
    - dotnet publish --no-restore -c Release -o ./docker/publish/

develop_build:
  <<: *build_template
  only:
    - develop
  artifacts:
    expire_in: 1 day
    paths:
      - docker/

.docker: &docker_template
  stage: publish
  image: docker:stable-dind
  script:
    - mkdir docker/app/
    - mv docker/publish/$ASSEMBLY_NAME.* docker/app/
    - mv docker/publish/*.config docker/app/
    - mv docker/publish/*.json docker/app/
    - cp Dockerfile docker/
    - docker build -t $TAG ./docker/
    - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
    - docker push $TAG

develop_docker:
  <<: *docker_template
  only:
    - develop
  dependencies:
    - develop_build
  variables:
    ASSEMBLY_NAME: app
    TAG: $CI_REGISTRY_IMAGE/$CI_COMMIT_REF_NAME:$CI_PIPELINE_ID

下面是我的 DockerFile：

# Dockerfile
FROM microsoft/dotnet:sdk AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers set
COPY ./DataStore/DataStore/*.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY *[^.csproj] ./
RUN dotnet publish -c Release -o out

# Build runtime images
FROM microsoft/dotnet:aspnetcore-runtime
ENTRYPOINT ["dotnet", "DataStore.dll"]

我想在将 C# Web API 部署到 Rancher 后运行它。
