Google Cloud Build 在更新镜像时找不到 kubernetes 部署

Question

我正在尝试使用 Cloud Build 设置 CI 管道。我的构建文件构建并推送 Docker 图像，然后使用 kubectl 构建器更新 kubernetes 部署中的图像。但是我收到以下错误：

Error from server (NotFound): deployments.extensions "my-app" not found
Running: kubectl set image deployment my-app my-app-api=gcr.io/test-project-195004/my-app-api:ef53550e2ahy784a14iouyh79712c9f

我已经通过 UI 验证部署处于活动状态并且具有该名称。认为这可能是权限问题，但据我所知，Cloud Build 服务帐户具有 Kubernetes Engine 管理员角色，并且能够在上一步中成功拉取集群身份验证数据。

编辑：根据要求，这是我的构建脚本：

steps:
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'gcr.io/$PROJECT_ID/my-app-api:$COMMIT_SHA', '-f', 'deploy/api/Dockerfile', '--no-cache', '.']
- name: 'gcr.io/cloud-builders/kubectl'
  args:
  - set
  - image
  - deployment
  - my-app
  - my-app=gcr.io/$PROJECT_ID/my-app-api:$COMMIT_SHA
  env:
  - 'CLOUDSDK_COMPUTE_ZONE=${_ZONE}'
  - 'CLOUDSDK_CONTAINER_CLUSTER=${_CLUSTER}'
images: ['gcr.io/$PROJECT_ID/my-app-api:$COMMIT_SHA']
timeout: 5000s

还有 deployment.yaml --

    deployment.kubernetes.io/revision: "1"

使用 kubectl 时需要为部署定义命名空间如果您没有使用默认命名空间。

因为您正在为部署使用命名空间 namespace: my-app，您需要使用 --namspace 标志将其添加到命令中。

下面是如何在里面做 cloudbuild.yaml

steps:
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'gcr.io/$PROJECT_ID/my-app-api:$COMMIT_SHA', '-f', 'deploy/api/Dockerfile', '--no-cache', '.']
- name: 'gcr.io/cloud-builders/kubectl'
  args:
  - set
  - image
  - deployment
  - my-app
  - my-app=gcr.io/$PROJECT_ID/my-app-api:$COMMIT_SHA
  - --namespace
  - my-app
  env:
  - 'CLOUDSDK_COMPUTE_ZONE=${_ZONE}'
  - 'CLOUDSDK_CONTAINER_CLUSTER=${_CLUSTER}'
images: ['gcr.io/$PROJECT_ID/my-app-api:$COMMIT_SHA']
timeout: 5000s

Google Cloud Build can't find kubernetes deployment when updating image
