aws elastic beanstalk docker部署期间出现内存不足错误答案

【问题描述】：

我尝试使用 Docker 映像在弹性 beanstalk 上创建环境。但是 Docker 映像需要大量内存进行部署。有办法减少吗？

它适用于“t2.medium”，但这对于节点项目来说太大了。我可以通过“t2.micro”处理吗？

EB 命令：

  export MY_APP=my-app-node
  export MY_ENV=my-environment-node
  eb init $MY_APP -r $AWS_DEFAULT_REGION -p "Docker"
  eb create $MY_ENV --single --instance-types t2.medium --envvars key1=val1 || echo "environment is already created."
  eb deploy $MY_ENV -l v-${BUILD_NUM}

Dockerfile 是：

FROM node:alpine
COPY package.json ./
RUN npm set progress=false && npm config set depth 0 && npm cache clean --force

## Storing node modules on a separate layer will prevent unnecessary npm installs at each build
RUN npm i && mkdir /ng-app && cp -R ./node_modules ./ng-app

WORKDIR /ng-app

COPY . .

## Build the angular app in production mode and store the artifacts in dist folder
RUN npm run config --configuration production && $(npm bin)/ng build --configuration production

FROM nginx:latest

## Copy our default nginx config
COPY nginx/default.conf /etc/nginx/conf.d/

## Remove default nginx website
RUN rm -rf /usr/share/nginx/html/*

EXPOSE 80

COPY --from=0 /ng-app/dist/demo-ng /usr/share/nginx/html

CMD ["nginx", "-g", "daemon off;"]

docker-compose.yml 文件：

version: '3.8'
services:
  web:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "80:80"
    env_file:
      - .env

【解决方案1】：

您的 Docker 映像似乎没有分配足够的内存：

在ElasticBeanstalk应用环境Dockerrun.aws.json，可以增加内存分配（"memory": 80到例如"memory": 100）：

"containerDefinitions": [
  {
  "name": "request_repeater",
  "image": "my/image",
  "essential": true,
  "memory": 80, <- change this

另外，也许您需要更改实例类型。例如t2.nano 的最大内存为0.5 GB

您可以在创建应用程序时在修改容量设置中执行此操作，或在当前环境配置的配置>容量设置中进行编辑。
