docker - 有关在 Google Cloud App Engine 上部署 Meteor 应用程序的问题：APP_CONTAINER_CRASHED

Question

TL;博士

克隆这个：https ://github.com/calvan-liang/radgrad2googlecloudissue 。

确保您安装了 meteor-google-cloud 和 gcloud CLI。如果不：

在 Powershell 上：

npm install meteor-google-cloud -g

在 Ubuntu 终端上：

echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] 
https://packages.cloud.google.com/apt cloud-sdk main" | sudo tee -a 
/etc/apt/sources.list.d/google-cloud-sdk.list

sudo apt-get install apt-transport-https ca-certificates gnupg

curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key --
keyring /usr/share/keyrings/cloud.google.gpg add -

sudo apt-get update && sudo apt-get install google-cloud-sdk

meteor-google-cloud --init

如果不成功或不是 Ubuntu：https ://cloud.google.com/sdk/install

要部署，在 app 目录中：

meteor-google-cloud --settings deploy/settings.json --app deploy/app.yml -- 
docker deploy/Dockerfile

APP_CONTAINER_CRASHED 的原因是什么，如何解决？

目前遵循https://github.com/EducationLink/meteor-google-cloud中的 README.md以使用 Google Cloud 部署预先存在的项目。在部署的第四步。默认服务正在更新时，我收到此错误：

使用的预先存在的项目是从https://github.com/radgrad/radgrad2克隆的。我在 radgrad2/app 中添加了一个部署目录。在部署目录中，有以下文件：

Dockerfile

FROM gcr.io/google_appengine/nodejs
RUN install_node {{ nodeVersion }}
RUN npm install npm@{{ npmVersion }}
RUN node -v
RUN npm -v
COPY . /app/
RUN (cd programs/server && npm install --unsafe-perm)
CMD node main.js

应用程序.yml

runtime: custom
service: default
env: flex
threadsafe: true
zones:
- us-west3-b
- us-west3-c
resources:
  cpu: 1
  memory_gb: 1
  disk_size_gb: 20
network:
  session_affinity: true
automatic_scaling:
  max_num_instances: 2
skip_files:
- ^(.*/)?\.dockerignore$
- ^(.*/)?\yarn-error.log$
- ^(.*/)?\.git$
- ^(.*/)?\.hg$
- ^(.*/)?\.svn$

设置.json

{
  "public": {},
  "private": {},
  "meteor-google-cloud": {
    "project": "radgrad2test",
    "stop-previous-version": "",
    "env_variables": {
      "MONGO_URL": "mongodb://user:[e-mail]",
      "ROOT_URL": "https://example.de"
    }
  }
}

请注意，我在 Windows 10 Home 上使用 WSL 2 和 Docker Desktop 运行它。

什么可能导致应用程序容器崩溃？我该如何解决这个问题，或者我应该在哪里寻找这个问题的根源？

MongoNetworkError：无法连接到服务器

这是最近在最新 Meteor 版本中修复的错误：

在一些 MongoDB 主机提供商（如 ScaleGrid 和 IBM Cloud）中，一些开发人员因为证书而收到此错误

MongoNetworkError：第一次连接时无法连接到服务器 [sg-meteorappdb-32194.servers.mongodirector.com:27017] [错误：自签名证书

所以为了解决这个问题，现在可以通过 Meteorsettings.json文件配置 Mongo 选项。它现在被添加到文档中：

"packages": {
  "mongo": {
    "options": {
      "tls": true,
      "tlsCAFileAsset": "certificate.pem"
    }
  }
}
