由于“无监视界面”，GitLab无服务器部署失败

Question

部署到GitLab中创建的Kubernetes集群中，指定后具有默认值

stages:
- build
- deploy

build:
  stage: build
  image:
    name: gcr.io/kaniko-project/executor:debug
    entrypoint: [""]
  only:
    - master
  script:
    - echo "{\"auths\":{\"$CI_REGISTRY\":{\"username\":\"$CI_REGISTRY_USER\",\"password\":\"$CI_REGISTRY_PASSWORD\"}}}" > /kaniko/.docker/config.json
    - /kaniko/executor --context $CI_PROJECT_DIR --dockerfile $CI_PROJECT_DIR/Dockerfile --destination $CI_REGISTRY_IMAGE

deploy:
  stage: deploy
  image: gcr.io/triggermesh/tm
  only:
    - master
  environment: production
  script:
    - echo "$CI_REGISTRY_IMAGE"
    - tm -n "$KUBE_NAMESPACE" --config "$KUBECONFIG" deploy service "$CI_PROJECT_NAME" --from-image "$CI_REGISTRY_IMAGE" --wait

在.gitlab-ci.yml和

中

FROM maven:3-jdk-11
COPY . .
RUN mvn --batch-mode --update-snapshots install
ENV PORT=8080
EXPOSE 8080
CMD java -jar target/hello-world-0.1-SNAPSHOT.jar

在Dockerfile阶段

由于以下原因而失败

$ tm -n "$KUBE_NAMESPACE" --config "$KUBECONFIG" deploy service "$CI_PROJECT_NAME" --from-image "$CI_REGISTRY_IMAGE" --wait

该项目是一个Spring Boot应用程序。根据Google Cloud控制台，集群运行状况良好。
