ECS and ECS Fargate usage guide

这里将展示如何利用本项目的 ECR 镜像地址部署 ecsworkshop 演示用例, 这里以宁夏区 cn-northwest-1 ECS Fargate 为例

安装ecs-cli，jq

依照 ecscli 安装指南 安装 ecscli

sudo curl -so /usr/local/bin/ecs-cli https://s3.amazonaws.com/amazon-ecs-cli/ecs-cli-linux-amd64-latest
sudo chmod +x /usr/local/bin/ecs-cli
sudo yum -y install jq gettext

# Setting environment variables required to communicate with AWS API's via the cli tools
export AWS_REGION=cn-northwest-1
aws configure set default.region ${AWS_REGION}
aws configure get default.region

部署示例应用

部署 ECS fargate 集群

cd ~/workspace/
git clone https://github.com/brentley/container-demo
aws cloudformation deploy --stack-name container-demo --template-file cluster-fargate-private-vpc.yml --capabilities CAPABILITY_IAM --region ${AWS_REGION}
aws cloudformation deploy --stack-name container-demo-alb --template-file script/alb-external.yml --region ${AWS_REGION}

部署前端服务 ecsdemo-frontend

  1. git clone 前端服务
cd ~/workspace/
git clone https://github.com/brentley/ecsdemo-frontend
  1. 修改镜像地址 ecsdemo-frontend/docker-compose.yml
version: '3'
services:
  ecsdemo-frontend:
    environment:
      - CRYSTAL_URL=http://ecsdemo-crystal.service:3000/crystal
      - NODEJS_URL=http://ecsdemo-nodejs.service:3000
    image: 048912060910.dkr.ecr.cn-northwest-1.amazonaws.com.cn/dockerhub/brentley/ecsdemo-frontend
    ports:
      - "3000:3000"
    logging:

        awslogs-group: ecsdemo-frontend
        awslogs-region: ${AWS_REGION}
        awslogs-stream-prefix: ecsdemo-frontend
  1. 部署 ecsdemo-frontend 前端服务

部署后端服务 ecsdemo-nodejs

git clone https://github.com/brentley/ecsdemo-nodejs
version: '3'
services:
  ecsdemo-nodejs:
    image: 048912060910.dkr.ecr.cn-northwest-1.amazonaws.com.cn/dockerhub/brentley/ecsdemo-nodejs
    ports:
      - "3000:3000"
    logging:
      driver: awslogs
      options: 
        awslogs-group: ecsdemo-nodejs
        awslogs-region: ${AWS_REGION}
        awslogs-stream-prefix: ecsdemo-nodejs

部署后端服务 ecsdemo-crystal

git clone https://github.com/brentley/ecsdemo-crystal

services:
  ecsdemo-crystal:
    image: 048912060910.dkr.ecr.cn-northwest-1.amazonaws.com.cn/dockerhub/brentley/ecsdemo-crystal

最终前端效果

alb_url=$(aws cloudformation describe-stacks --stack-name container-demo-alb --query 'Stacks[0].Outputs[?OutputKey==`ExternalUrl`].OutputValue' --output text --region $AWS_REGION)
echo "Open $alb_url in your browser"
