Couchbase Server comes in two editions: - [Community Edition](http://www.couchbase.com/community) -- free for unrestricted use. - [Enterprise Edition](http://www.couchbase.com/agreement/subscription) -- free for development, paid subscription required for production deployment. By default, the `latest` Docker tag points to the latest Enterprise Edition, as does the `enterprise` Docker tag. If you want the Community Edition instead, you should add the `community` tag, which will point to the latest available Community Edition. Docker run couchbase:community
