云构建无法找到DockerFile

Question

我试图使用谷歌云构建触发器构建我的docker容器。不幸的是，构建没有找到我的docker文件。它不在我的存储库的根目录下，但我认为我可以指定一个相对路径。显然我配置错误了。下面是我的cloudbuild.yaml和输出日志。

如果有关系的话——我的代码在github中，但我将触发器配置为从该回购中提取。

steps:
- name: 'gcr.io/cloud-builders/docker'
  args:
  - 'build'
  - '--tag=gcr.io/$PROJECT_ID/domain-session-test:$TAG_NAME'
  - '--file=session_server/deployments/DockerFiles/minimal.Dockerfile'
  - '.'
- name: 'gcr.io/cloud-builders/docker'
  args: ['run', 'gcr.io/$PROJECT_ID/domain-session-test:$TAG_NAME', 'go', 'test']
- name: 'gcr.io/cloud-builders/gsutil'
  args: ['cp', '-r', 'k8s/*', 'gs://$PROJECT_ID-kubernetes-manifests']
images: ['gcr.io/$PROJECT_ID/domain-session-test:$TAG_NAME']

日志：

当使用.作为Docker上下文时，我遇到了类似的情况。

我犯了这个错误。。。

unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /workspace/Dockerfile: no such file or directory

...当使用cloudbuild时。yaml与此类似：

steps:
# Build the container image
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'gcr.io/[PROJECT_ID]/[IMAGE]', '.']
# Push the image to Container Registry
- name: 'gcr.io/cloud-builders/docker'
  args: ['push', 'gcr.io/[PROJECT_ID]/[IMAGE]']
# Deploy image to Cloud Run
- name: 'gcr.io/cloud-builders/gcloud'
  args:
  - 'run'
  - 'deploy'
  - '[SERVICE_NAME]'
  - '--image'
  - 'gcr.io/[PROJECT_ID]/[IMAGE]'
  - '--region'
  - '[REGION]'
  - '--platform'
  - 'managed'
images:
- gcr.io/[PROJECT_ID]/[IMAGE]

而我的Cloud Build触发器定义知道在哪里可以找到cloudbuild。yaml文件，它显然使用repo根目录中的工作目录执行，而repo根目录不包含Dockerfile。

如果我使用类似于下面的构建步骤，问题就解决了。

# Build the container image
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'gcr.io/[PROJECT_ID]/[IMAGE]', '<DIR_CONTAINING_DOCKERFILE>']
