roverdotcom/syslog repository overview

⁠One syslog to rule them all

1. Build the syslog container:

   docker build -t syslog .

2. Run it (replace logging.example.com with the fqdn of your central syslog server):

   docker run -e "SYSLOG_SERVER=logging.example.com" --name syslog -d -v /tmp/syslogdev:/dev syslog

3. Start another container to send logs:

   docker run -v /tmp/syslogdev/log:/dev/log ubuntu logger hello

4. Use the docker-exec command to inspect syslog container directly, after some logs have been generated

   docker exec -t syslog tail -f /var/log/syslog

5. See in the log message show up in the "tail" container.

⁠Env Vars

• LOGGLY_HOST - get from loggly
• LOGGLY_API_KEY - get from loggly
• LOGGLY_TAG - e.g., production, staging, docker-east
