Hi,

I am having issues with passing ec2 instance provisioning results to other tasks in a playbook.

I can launch instances, and then use "

register: ec2

" to register a dictionary of the results. But I cannot seem to extract the instance id later.

Using debug I can see i get valid results:

TASK [debug] ******************************************************************* ok: [localhost] => { "ec2.results": [ { "_ansible_no_log": false, "changed": true, "instance_ids": [ "i-5bbc7cee" ], "instances": [ { "ami_launch_index": "0", "architecture": "x86_64", "block_device_mapping": { "/dev/xvda": { "delete_on_termination": true, "status": "attached", "volume_id": "vol-352da188" } }, "dns_name": "", "ebs_optimized": false, "groups": { "sg-2b37d84f": "mongo" }, "hypervisor": "xen", "id": "i-5bbc7cee", "image_id": "ami-d1f482b1", "instance_type": "t2.micro", "kernel": null, "key_name": "keypair", "launch_time": "2016-03-11T13:33:09.000Z", "placement": "us-west-1c", "private_dns_name": "ip-172-x-x-x.us-west-1.compute.internal", "private_ip": "x.x.x.x", "public_dns_name": "", "public_ip": null, "ramdisk": null, "region": "us-west-1", "root_device_name": "/dev/xvda", "root_device_type": "ebs", "state": "running", "state_code": 16, "tags": { "Name": "mongo", }, "tenancy": "default", "virtualization_type": "hvm" } ], "invocation": { "module_args": { "assign_public_ip": false, "aws_access_key": "xxxxxxxxxxxxxxxxxxxxxx", "aws_secret_key": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "count": 1, "count_tag": { "volumes": "data" }, "ebs_optimized": false, "ec2_url": null, "exact_count": null, "group": [ "mongo" ], "group_id": null, "id": null, "image": "ami-d1f482b1", "instance_ids": null, "instance_profile_name": null, "instance_tags": { "Name": "mongo", }, "instance_type": "t2.micro", "kernel": null, "key_name": "keypair", "monitoring": false, "network_interfaces": null, "placement_group": null, "private_ip": null, "profile": null, "ramdisk": null, "region": "us-west-1", "security_token": null, "source_dest_check": true, "spot_price": null, "spot_type": "one-time", "spot_wait_timeout": 600, "state": "present", "tenancy": "default", "termination_protection": false, "user_data": null, "validate_certs": true, "volumes": null, "vpc_subnet_id": "subnet-703aa229", "wait": true, "wait_timeout": 300, "zone": null }, "module_name": "ec2" }, "item": "mongo", "tagged_instances": [] } ] } TASK [debug] ******************************************************************* ok: [localhost] => { "ec2.results.instances": "VARIABLE IS NOT DEFINED!" } TASK [debug] ******************************************************************* ok: [localhost] => { "ec2.results.instance_ids": "VARIABLE IS NOT DEFINED!" } TASK [debug] ******************************************************************* ok: [localhost] => { "ec2.results.tagged_instances": "VARIABLE IS NOT DEFINED!" } TASK [debug] ******************************************************************* ok: [localhost] => { "ec2.results.0.instances.0.id": "i-5bbc7cee" }

The ec2 examples show using:

- ec2_vol: 
   instance: "{{ item.id }} " 
   volume_size: 5 
  with_items: ec2.instances 
  register: ec2_vol

But that does not work, based on the above debugs, I tried:



 

    -  ec2_vol: 

       instance: "{{ item.id }}" 

       volume_size: 10 

      with_items: ec2.results.0.instances 

      register: ec2_vol

Well, after some more painful trial and error, and pissing Amazon off for sure, here's a working solution:

I hope this saves someone some pain in the future.

 - name: data volumes
         ec2_vol: 
         aws_access_key: "{{ key }}" 
         aws_secret_key: "{{ secret }}" 
         instance: "{{ item.instances.0.id }}" 
         region: "{{item.instances.0.region}}" 
         name: "{{ item.instances.0.tags.Name }}_data" 
         volume_size: {{data_vol_size}} 
         volume_type: gp2 
         device_name: /dev/xvdb 
         with_items: ec2.results 
         register: ec2_vol
