amazon web services - How to launch a task ECS on AWS with PHP -

i try launch "taskdefinition" on ecs (ec2 container service) php sdk.

1. i created taskdefinition.
2. i created cluster.
3. i created service.

i thought next step "registercontainerinstance" when call method, have error :

[aws\ecs\exception\ecsexception]
error executing "registercontainerinstance" on "https://ecs.eu-west-1.amazonaws.com"; aws http error: client error: 400 clientexception (client): identity document provided, not valid. - {" __type":"clientexception","message":"an identity document provided, not valid."}

this because don't send "instanceidentitydocument" , "instanceidentitydocumentsignature". but, don't know how 2 parameters.

should launch ec2 manually before?

is there way do not know?

i found solution problem :

first, need create task "registertaskdefinition" :

$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 : '".$taskname."' has been created\n";             else                 echo  "task : '".$taskname."' has been updated\n";         }         else             echo "error : task not active.\n"; 

the file 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": [] } 

then, need create cluster :

$clustername = $this->ecsclient->createcluster([             'clustername' => 'test',         ]); 

then, service :

$result = $this->ecsclient->createservice([             'desiredcount' => 1,             'servicename' => 'servicename',             'taskdefinition' => 'taskname',             'cluster' => 'test'         ]); 

after that, have start ec2 instance :

$result = $this->ec2client->runinstances([             'imageid'        => 'ami-2aaef35d',             'mincount'       => 1,             'maxcount'       => 1,             'instancetype'   => 't2.micro',             'userdata'       => base64_encode("#!/bin/bash \r\n echo ecs_cluster=test >> /etc/ecs/ecs.config"),             'iaminstanceprofile' => [                 'arn' => 'arnec2'             ],          ]); 

when ec2 ready, can start task :

$result = $this->ecsclient->runtask([             'taskdefinition' => 'taskname',             'cluster' => 'test'         ]);
