Detailed Description

Describes how the containerizer redirects I/O for stdin/stdout/stderr of a container.

See process::Subprocess::IO.

NOTE: This wrapper prevents the containerizer from redirecting I/O via a Subprocess::PIPE. This is restricted because the IO of a container must not be affected by the status of the agent process:

• A Subprocess::PIPE will require the agent process to regularly read and empty the pipe. The agent does not do this. If the pipe fills up, the write-end of the pipe may become blocked on IO.
• Redirection must continue even if the agent dies.
