Unable to upload files to DigitalOcean Spaces using Ansible

Posted November 26, 2017 6k views

Using the Ansible 2.4.1.0 on a Ubuntu 16.04 target, I’m unable to upload files to DigitalOcean Spaces using aws_s3 module.

This is the playbook task:

    - name: Uploading backup
      aws_s3:
        aws_access_key: "..."
        aws_secret_key: "..."
        region: nyc3
        s3_url: "https://nyc3.digitaloceanspaces.com"
        bucket: "working-bucket"
        object: "my_file.tar.gz"
        src: "my_file.tar.gz"
        mode: put
        rgw: True

and this is the error:

   "changed":false,

   "msg":"MODULE FAILURE",
   "rc":0
}

Does anyone managed to make it work? I’m not sure if this a problem in Ansible or just something else because there’s a little of upload activity before the error happens.

(also reported in the Ansible repo)

I was running into this same issue myself, and was able to track down the problem. DigitalOcean Spaces does not support currently support the x-amz-server-side​-encryption header. Ansible is setting this by default. Adding encrypt: false to the put task allows it to proceed as expected.

Here is a full working example of creating a bucket, uploading a file to it, and then listing its contents:

---
- hosts: localhost
  vars:
    spaces_access_key: "{{ lookup('env','SPACES_ACCESS_KEY') }}"
    spaces_secret_key: "{{ lookup('env','SPACES_SECRET_KEY') }}"
    spaces_endpoint: https://nyc3.digitaloceanspaces.com
    spaces_region: nyc3
    space_name: my-ansible-bucket-001
    key_name: file.ext
    file_path: /path/to/my/file.ext

  tasks:
    - name: Creating Space
      aws_s3:
        aws_access_key: "{{ spaces_access_key }}"
        aws_secret_key: "{{ spaces_secret_key }}"
        s3_url: "{{ spaces_endpoint }}"
        bucket: "{{ space_name }}"
        mode: create
        rgw: True

    - name: Uploading object
      aws_s3:
        aws_access_key: "{{ spaces_access_key }}"
        aws_secret_key: "{{ spaces_secret_key }}"
        s3_url: "{{ spaces_endpoint }}"
        bucket: "{{ space_name }}"
        object: "{{ key_name }}"
        src: "{{ file_path }}"
        mode: put
        encrypt: false
        rgw: true

    - name: List objects in Space
      aws_s3:
        aws_access_key: "{{ spaces_access_key }}"
        aws_secret_key: "{{ spaces_secret_key }}"
        s3_url: "{{ spaces_endpoint }}"
        bucket: "{{ space_name }}"
        mode: list
        rgw: true
      register: spaces_items

    - debug:
        msg: "Contents of {{ space_name }}: {{ spaces_items.s3_keys }}"

Are you using Signature v4 for the API requests? I believe Spaces is currently not compatible with this.

    I’m not sure which version of the Signature is Ansible using.

    As other tasks works (listing and downloading files, for example), my guess is that they’re using v2.
