我可以使用Container Registry触发器来进行GAE灵活的Node.js部署吗？

Question

我从以下教程学习了如何使用Container Registry触发器进行Google Cloud Functions部署。

Automatic serverless deployments with Cloud Source Repositories and Container Builder

我有Google App引擎灵活的应用。运行时是Node.js.我想部署由git push触发的应用程序。有什么好的参考资料吗？

我正在使用这些示例代码。手动部署正常。

* tree

├── app.js
├── app.yaml
└── package.json

* app.js

'use strict';
const express = require('express');
const app = express();
app.get('/', (req, res) => {
  res.status(200).send('Hello, world!').end();
});
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
  console.log(`App listening on port ${PORT}`);
console.log('Press Ctrl+C to quit.');
});

我发现了一个类似的问题。

How to auto deploy google app engine flexible using Container Registry with Build Trigger

我添加了cloudbuild.yaml。

steps:
# Build the Docker image.
- name: gcr.io/cloud-builders/docker
args: ['build', '-t', 'gcr.io/$PROJECT_ID/app', '.']
# Push it to GCR.
- name: gcr.io/cloud-builders/docker
args: ['push', 'gcr.io/$PROJECT_ID/app']
# Deploy your Flex app from the image in GCR.
- name: gcr.io/cloud-builders/gcloud
args: ['app', 'deploy', 'app.yaml', '--image-url=gcr.io/$PROJECT_ID/app']
# Note that this build pushes this image.
images: ['gcr.io/$PROJECT_ID/app']

然而，我收到了一个错误。错误消息是＆＃34; 错误加载模板：yaml：第5行：找不到预期的密钥＆＃34;。我正在研究它。

更新2

原因是yaml格式无效。我改变了它，如下所示。

steps:
  # Build the Docker image.
- name: gcr.io/cloud-builders/docker
  args: ['build', '-t', 'gcr.io/$PROJECT_ID/app', '.']
  # Push it to GCR.
- name: gcr.io/cloud-builders/docker
  args: ['push', 'gcr.io/$PROJECT_ID/app']
  # Deploy your Flex app from the image in GCR.
- name: gcr.io/cloud-builders/gcloud
  args: ['app', 'deploy', 'app.yaml', '--image-url=gcr.io/$PROJECT_ID/app']
  # Note that this build pushes this image.
  images: ['gcr.io/$PROJECT_ID/app']

我又出了一个错误。消息是＆＃34; 错误加载模板：未知字段＆＃34;图像＆＃34;在cloudbuild_go_proto.BuildStep ＆＃34;

更新3

我注意到＆＃34;图像＆＃34;缩进是错误的。

steps:
  ...
# Note that this build pushes this image.
images: ['gcr.io/$PROJECT_ID/app']

我遇到了新的错误。

是。我没有Dockerfile，因为我使用Google App Engine灵活的Environment Node.js运行时。这不是Docker。

更新4

我添加了Dockerfile

FROM gcr.io/google-appengine/nodejs

然后发生了新的错误。

Step #2: ERROR: (gcloud.app.deploy) User [xxxxxxx@cloudbuild.gserviceaccount.com] does not have permission to access app [xxxx] (or it may not exist): App Engine Admin API has not been used in project xxx before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/appengine.googleapis.com/overview?project=xxx then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

更新5

我启用了App Engine Admin API，然后出现了下一个错误。

Step #2: Do you want to continue (Y/n)? 
Step #2: WARNING: Unable to verify that the Appengine Flexible API is enabled for project [xxx]. You may not have permission to list enabled services on this project.

Step #2: Beginning deployment of service [default]...
Step #2: WARNING: Deployment of service [default] will ignore the skip_files field in the configuration file, because the image has already been built.

Step #2: npm ERR! enoent This is related to npm not being able to find a file.

我更改了我的代码树，但它没有用。我确认已启用Appengine Flexible API。我不知道接下来应该尝试什么。

.

├── app
│   ├── app.js
│   └── package.json
├── app.yaml
└── cloudbuild.yaml

更新6

当我手动部署时，工件如下所示。

us.gcr.io/xxxxx/appengine/default.20180316t000144

我应该使用这个神器......？我很困惑..

更新7

执行两个构建。我不知道这是否正确。

Answer 1

您的Dockerfile不会将源复制到图像。

您可以将所有内容移回同一目录，以便

.
├── app.js
├── app.yaml
├── cloudbuild.yaml
├── Dockerfile
└── package.json

但没关系。

将其粘贴到您的Dockerfile中，它应该可以工作：

FROM gcr.io/google-appengine/nodejs

# Working directory is where files are stored, npm is installed, and the application is launched
WORKDIR /app

# Copy application to the /app directory.
# Add only the package.json before running 'npm install' so 'npm install' is not run if there are only code changes, no package changes
COPY package.json /app/package.json
RUN npm install
COPY . /app

# Expose port so when container is launched you can curl/see it.
EXPOSE 8080

# The command to execute when Docker image launches.
CMD ["npm", "start"]

编辑：这是我使用的cloudbuild.yaml：

steps:
- name: gcr.io/cloud-builders/docker
  args: ['build', '-t', 'gcr.io/$PROJECT_ID/app', '.']
- name: gcr.io/cloud-builders/docker
  args: ['push', 'gcr.io/$PROJECT_ID/app']
- name: gcr.io/cloud-builders/gcloud
  args: ['app', 'deploy', 'app.yaml', '--image-url=gcr.io/$PROJECT_ID/app'] 
images: ['gcr.io/$PROJECT_ID/app']

Answer 2

一个技术人员帮助了我。我更改了目录结构和cloudbuild.yaml。然后它奏效了。感谢。
