Reopening because this may be a problem for Windows CouchDB servers. Thanks for the report.

Sorry, my mistake. Looking at this code, it's not changed in years - we probably have never been able to support Windows-hosted Docker containers where the data directory is mapped to a local file system under Windows.
This probably should be added to the Docker documentation.

@pavellzubkov How long did the problem persist?
`ebusy` means the file was busy and in use. The error message suggests the compactor was finishing up compacting your view by swapping files around. It should have been a transient error.

The error is coming from https://github.com/apache/couchdb/blob/master/src/couch_mrview/src/couch_mrview_compactor.erl#L232 which is where the compactor attempts to delete the index file after swapping.
One possible explanation is that you're running Docker on Windows, are mapping your data directory to a Windows file system, and something is still holding the file open. (File locking mechanisms on Windows differ from those on Unix.)
If this is Docker running on a Linux host, I'm not sure.
