Does Docker Community Edition support secrets management in any form?

I was confused by this as well. I spoke to a developer at Docker and they stated the following:

The 'secrets mgmt' listed isn't 'secrets' itself. secrets is part of the open source project and definitely part of CE. The pricing page will be revised, sorry for the confusion.

So it looks like secrets will stay around and the EE version will have a more robust version.

Hope this helps.
