Instance Method Details

#auto_detection_choices ⇒ Object

Displays a prompt for known IaaS that are configured within .fog config file if found.

If no ~/.fog file found or user chooses “Alternate credentials” then no changes are made to settings.

For example:

  1. AWS (default)

  2. AWS (bosh)

  3. Alternate credentials

Choose infrastructure: 1

If .fog config only contains one provider, do not prompt.

fog config file looks like: :default:

:aws_access_key_id:     PERSONAL_ACCESS_KEY
:aws_secret_access_key: PERSONAL_SECRET

:bosh:

:aws_access_key_id:     SPECIAL_IAM_ACCESS_KEY
:aws_secret_access_key: SPECIAL_IAM_SECRET_KEY

Convert this into: { “AWS (default)” => => …, “AWS (bosh)” => … }

Then display options to user to choose.

Currently detects following fog providers:

  • AWS

  • OpenStack

If “Alternate credentials” is selected, then user is prompted for fog credentials:

  • provider?

  • access keys?

  • API URI or region?

Sets (unless ‘Alternate credentials’ is chosen)

  • settings.provider.name

  • settings.provider.credentials

For AWS, the latter has keys:

{:aws_access_key_id, :aws_secret_access_key}

For OpenStack, the latter has keys:

{:openstack_username, :openstack_api_key, :openstack_tenant
   :openstack_auth_url, :openstack_region }
