forward

Forwards StdIn data to a remote destination over UDP/TCP/TCP+TLS.
Defaults to connecting via TCP+TLS and teeing input to stdout

Data is buffered until reaching a newline char before being sent over the network. Should the connection fail to connect or the connection is lost, forward will not panic so the upstream process can continue uninterrupted.

Future work:
Possibly reconnect TCP connection if lost.

Why?

Papertrail's recommended approach is to use logger with rsyslogd. For the following reasons, it may be beneficial to use this instead.

1. You're using a small image of Alpine linux which doesn't have rsyslogd pre-installed
2. You need security but your version of netcat doesn't support TLS
3. You just want to log something quickly without syslog config
