Several errors are seen across different Dataflow jobs.

- Failed to get event map[error:rpc error: code = Unavailable desc = transport is closing module:libcontainerd namespace:moby]
- Failed to create directory or subvolume "/root/.ssh": Read-only file system
- Failed to get event map[error:rpc error: code = Unavailable desc = error reading from server: EOF module:libcontainerd namespace:moby] 
- Failed to get event map[error:rpc error: code = Unavailable desc = error reading from server: EOF module:libcontainerd namespace:plugins.moby]

Although jobs are finished successfully, however, those messages are not well-documented on the document for determining whether they are ignorable or not.

Other information (workarounds you have tried, documentation consulted, etc):

The Dataflow product team has clarified that these messages are benign and not impact jobs running. In addition, the Dataflow product team has been working on improving the user experience of Dataflow logging.
