如何使用PHP在AWS上启动任务ECS

Question

我尝试用PHP SDK在ECS (Ec2容器服务)上启动我的"TaskDefinition"。

我创建了TaskDefinition。我创建了群集。我创建了服务。

我认为下一步将是"registerContainerInstance"，但当我调用这个方法，我有一个错误:

Aws Ecs 例外 [EcsException]
执行"RegisterContainerInstance"时出错"https://ecs.eu -西方- 1. amazonaws.com";AWS HTTP错误:客户端错误400 ClientException (client):提供了身份证件，但是不是有效的。—{" __type":"ClientException"，"message":"标识文件已提供，但无效。"}

这是因为我不发送"instanceIdentityDocument"one_answers"instanceIdentityDocumentSignature"。但是，我不知道如何得到这两个参数。

我应该之前手动启动EC2吗?

还有我不知道的方法吗?

我终于找到解决问题的办法了:

首先，你需要用"registerTaskDefinition"创建任务:

$file = file_get_contents('config/configEC2basic.json');
        $data = json_decode($file, true /* associative arrays */);
        $result = $this->ecsClient->registerTaskDefinition($data);
        if ($result['taskDefinition']['status'] == "ACTIVE")
        {
            $taskName = $result['taskDefinition']['containerDefinitions'][0]['name'];
            if ($result['taskDefinition']['revision'] == 1)
                echo "Task : '".$taskName."' has been createdn";
            else
                echo  "Task : '".$taskName."' has been updatedn";
        }
        else
            echo "Error : The task is not active.n";

文件config/configEC2basic。json:

{
    "containerDefinitions": [{
        "command": [],
        "cpu": 1,
        "entryPoint": ["/usr/sbin/apache2ctl -D FOREGROUND"],
        "environment": [],
        "essential": true,
        "image": "usernamedockerhub/dockercontainer",
        "links": [],
        "memory": 500,
        "mountPoints": [],
        "name": "nameTask",
        "portMappings": [{
            "containerPort": 80,
            "hostPort": 80,
            "protocol": "tcp"
        }],
        "volumesFrom": []
    }],
    "family": "familyTask",
    "volumes": []
}

然后，需要创建集群:

$clusterName = $this->ecsClient->createCluster([
            'clusterName' => 'test',
        ]);

然后，服务:

$result = $this->ecsClient->createService([
            'desiredCount' => 1,
            'serviceName' => 'serviceName',
            'taskDefinition' => 'taskName',
            'cluster' => 'test'
        ]);

之后，您必须启动EC2实例:

$result = $this->ec2Client->runInstances([
            'ImageId'        => 'ami-2aaef35d',
            'MinCount'       => 1,
            'MaxCount'       => 1,
            'InstanceType'   => 't2.micro',
            'UserData'       => base64_encode("#!/bin/bash rn echo ECS_CLUSTER=test >> /etc/ecs/ecs.config"),
            'IamInstanceProfile' => [
                'Arn' => 'ARNEC2'
            ],
        ]);

当你的EC2准备好了，你可以开始你的任务:

$result = $this->ecsClient->runTask([
            'taskDefinition' => 'taskName',
            'cluster' => 'test'
        ]);
