篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了[AWS][容器][ECS] ECS动手实验101相关的知识，希望对你有一定的参考价值。

实验目的，熟悉AWS Elastic Container Service

实验包括：

1. 创建和定义ECS的任务（Task）

2. 创建ECS Cluster

3. 部署应用到ECS Service中

实验前准备：

AWS账号
熟悉IAM role、EC2、Docker等知识

Task1：使用ecs-sample image注册和定义Task

进入到ECS服务，创建Task Definitions：

{
  "family": "myContainer",
  "containerDefinitions": [
    {
      "volumesFrom": [],
      "portMappings": [
        {
          "hostPort": 80,
          "containerPort": 80
        }
      ],
      "command": null,
      "environment": [],
      "essential": true,
      "entryPoint": null,
      "links": [],
      "mountPoints": [
        {
          "containerPath": "/usr/local/apache2/htdocs",
          "sourceVolume": "my-vol",
          "readOnly": null
        }
      ],
      "memory": 300,
      "name": "simple-app",
      "cpu": 10,
      "image": "httpd:2.4"
    },
    {
      "volumesFrom": [
        {
          "readOnly": null,
          "sourceContainer": "simple-app"
        }
      ],
      "portMappings": [],
      "command": [
        "/bin/sh -c "while true; do echo ‘<html> <head> <title>Amazon ECS Sample App</title> <style>body {margin-top: 40px; background-color: #333;} </style> </head><body> <div style=color:white;text-align:center> <h1>Amazon ECS Sample App</h1> <h2>Congratulations!</h2> <p>Your application is now running on a container in Amazon ECS.</p>‘ > top; /bin/date > date ; echo ‘</div></body></html>‘ > bottom; cat top date bottom > /usr/local/apache2/htdocs/index.html ; sleep 1; done""
      ],
      "environment": [],
      "essential": false,
      "entryPoint": [
        "sh",
        "-c"
      ],
      "links": [],
      "mountPoints": [],
      "memory": 200,
      "name": "busybox",
      "cpu": 10,
      "image": "busybox"
    }
  ],
  "volumes": [
    {
      "host": {
        "sourcePath": null
      },
      "name": "my-vol"
    }
  ]
}

导入之后，回头看Task Definition Name为：myContainer。然后Task size等信息也定义好了。
