[Pulp-list] Issues with using S3 storage when running pulp on Amazon EC2 (pulp3)

[Dumont, Joey]

Turns out the issue was on my end. I had to add aws_default_acl: None to the pulp_settings section of the playbook. The public-read ACL was incompatible with the BlockPublicAccess settings that I had set on my S3 bucket. ?

I'm now encountering a different issue, but I'll start another thread for that one.

Thanks for the pointers, they were very helpful!

Unfortunately I don't know of a good way to debug the problem other than to dig into the code. If you want to debug from the Pulp code, you could stick a debugger in the artifact saver stage:

https://github.com/pulp/pulpcore/blob/2203fee1407738a4ddd8e644fcbc741aab0bca63/pulpcore/plugin/stages/artifact_stages.py#L179-L200

What I would probably do though is stick a debug statement here in django-storages to see what params it's passing to boto3:

https://github.com/jschneier/django-storages/blob/0ab2b1e3efd2bcaf0f24540a718993acc7742d9b/storages/backends/s3boto3.py#L511

You can see the location of django-storages with `pip show django-storages`.

Sorry I don't have a better answer for you. Perhaps this is something we can improve in the future. Also, I'd be curious as to what the issue is as it sounds like everything should work in theory.

I've installed the latest pulp3 using the Ansible installer using the following playbook:

      - django-storages
      - boto3
    pulp_use_system_wide_pkgs: True
    pulp_default_admin_password: !vault |

          ...
    pulp_settings:
      secret_key: !vault |
          $ANSIBLE_VAULT;1.1;AES256
          ...
      default_file_storage: 'storages.backends.s3boto3.S3Boto3Storage'

      aws_s3_region_name: 'ca-central-1'
      aws_s3_addressing_style: "path"
      media_root: '/pulp3/'
    pulp_install_plugins:
      pulp-file: {}
      pulp-rpm:
        prereq_role: "pulp.pulp_rpm_prerequisites"
        #      pulp-docker: {}
  roles:
    - pulp-database
    - pulp-workers
    - pulp-resource-manager
    - pulp-webserver
    - pulp-content
  environment:
    DJANGO_SETTINGS_MODULE: pulpcore.app.settings

I also set up an RPM repo that uses S3 for storage. However, when I try to sync, I get an AccessDenied error. I know the instance profile is correct, as I can upload objects from that instance using both the AWS CLI and Boto3 without specifying credentials.

How can I debug this further? Is there a way for me know what parameters are passed to the put_object boto3 call by the sync task?

Cheers,
