Get all key from output

Hi all, I need to get the id of all available volumes in amazon aws, to make it I have created the following

2

You can use json_query to create a list of just the volume IDs.

3

When you say “aws_volume.volumes[0]”, you’re explicitly looking at only the first volume, so your statement “… and should show me all” is incorrect; it should show you only the first volume.

Try something like this (untested):

  • name: “show”
    debug:
    msg: “{{ item.id }}”
    loop: “{{ aws_volume.volumes }}”
4

I understand, I could make it work, but not by using the ec2 snapshot module.

I try to save a key as a variable but the result is empty

ok: [localhost] => {
“ansible_facts”: {
“snap_id”: “”
},
“changed”: false
}

You need to first look at the registered out snapshot_info to see what its dictionary looks like. After you snapshot the EC2, insert a debug: var=snapshot_info to see what you are being given back. With that you can to then construct a proper reference to the snapshot_id.

According to the ansible docs you get a single snapshot_id.

snapshot_info.snapshot_id should get you the reference you need. It isn’t clear from the docs whether that is a list if the EC2 has multiple EBS volumes attached.

Are you missing a parameter “snapshot_id” in your definition of “ec2_snapshot”?

9

Please change this:

  • name: “Debug”
    debug:
    msg: “{{ item.snapshot_id }}”
    with_items: “{{ snapshotid }}”

to this:

  • name: “Debug”
    debug: var=snapshotid

So you can see the entire registered result returned from the prior task.

ok: [localhost] => {
“msg”: “var=snapshotid"”
}

i think the “register” not work

11

I don’t know what I’m doing wrong, I’m desperate.
any help?

12

The register worked fine, but there’s a typo in your debug task, which you have not shown us.

13

i Try this tasks:

14
  • name: “mostrando”
    debug:
    msg: var=show_id_snapshot

should be

  • name: “mostrando”
    debug: var=show_id_snapshot

or

  • name: “mostrando”
    debug:
    var: show_id_snapshot

or

  • name: “mostrando”
    debug:
    msg: “{{ show_id_snapshot }}”

Walter

15

Ok, the output shows me what I have been showing in previous answers.

Here my playbook

16

Change this:

  • name: “mostrando”
    debug: var=show_id_snapshot.snapshot_id

to

  • name: “mostrando”
    debug: var=show_id_snapshot

so we can see the entirety of what is registered.

Looks like the reference to snapshot_id should be:

set_fact:
snap_id: “{{ show_id_snapshot.results[0].snapshot_id }}”

or to get a list if there are multiples:

set_fact:
snap_id: {{ show_id_snapshot.results | json_query(‘.snapshot_id’) | list }}

Thanks. I’m ashamed I hope you can forgive me for bothering so much.

We all learn from experience and the help of others. Nothing to be ashamed about.
